Graph-Based Data Science: Hybrid AI meets data science process | Paco Nathan
6 januari 2025 · 36 min
Python offers excellent libraries for working with graphs: semantic technologies, graph queries, interactive visualizations, graph algorithms, probabilistic graph inference, as well as embedding and other integrations with deep learning. Lees meer
However, most of these approaches share little common ground, nor do many of them integrate effectively with popular data science tools (pandas, scikit-learn, spacy, pytorch), nor efficiently with popular data engineering infrastructure such as Spark, RAPIDS, Ray, Parquet, fsspect, etc.
In this podcast episode, Paco Nathan reviews kglab – an open source project that integrates most all of the above, and moreover provides ways to leverage disparate techniques in ways that complement each other, to produce Hybrid AI solutions for industry use cases.

Enterprise Knowledge Graphs: Breaking Through Organizational Inertia to Reimagine Data Management | Panel Discussion
2 december 2024 · 39 min
Industry leaders from Accenture, Johnson & Johnson, and the Enterprise Knowledge Graph Foundation dive deep into the transformative potential of knowledge graphs, exploring how these semantic technologies are revolutionizing enterprise data management. Lees meer
Featuring Mike Atkin, Laurent Alquier and Teresa Tung.
The conversation reveals a critical shift from traditional data processing to a more nuanced, context-rich approach that prioritizes data meaning and reusability. Participants discuss how organizations are moving beyond experimental pilots to enterprise-wide implementations, driven by a growing recognition that data incongruence is a significant liability in today's data-driven business landscape.
The discussion unveils the key challenges of knowledge graph adoption:
* Overcoming organizational inertia
* Bridging technological gaps, and
* Fundamentally changing mindsets about data representation.
Experts share insights into the importance of telling compelling stories about knowledge graphs, focusing on business value rather than technical complexity. They emphasize the need for incremental implementation, collaborative approaches, and the crucial role of knowledge engineers who can translate between technical capabilities and business needs.
We've arrived at a pivotal moment for enterprise knowledge graphs: the technology has matured, business leaders are increasingly receptive, and there's a growing understanding that these semantic technologies offer more than just another IT solution.
Knowledge graphs represent a fundamental reimagining of how organizations can capture, understand, and leverage their data—moving away from the myth of a single version of truth towards a more flexible, context-rich approach that allows multiple perspectives to coexist. For businesses looking to remain competitive in a data-driven world, the message is clear: the time to start building knowledge graphs is now.

Rebooting AI: Adding Knowledge to Deep Learning | Gary Marcus
3 november 2024 · 39 min
Gary Marcus argues for a shift in research priorities, towards four cognitive prerequisites for building robust artificial intelligence: Lees meer
Hybrid architectures that combine large-scale learning with the representational and computational powers of symbol-manipulation
Large-scale knowledge bases—likely leveraging innate frameworks—that incorporate symbolic knowledge along with other forms of knowledge
Reasoning mechanisms capable of leveraging those knowledge bases in tractable ways
And rich cognitive models that work together with those mechanisms and knowledge bases.
Although there are real problems to be solved here, and a great deal of effort must go into constraining symbolic search well enough to work in real time for complex problems, Google Knowledge Graph seems to be at least a partial counterexample to this objection, as do large scale recent successes in software and hardware verification.

Data Revolution: The Emergence of the Decentralized Enterprise Knowledge Graph | Tony Seale
2 juni 2024 · 32 min
An AI tsunami is on the rise, and the past few months have only amplified it. To survive it and thrive in tomorrow’s economy, organizations big and small must rethink the way they do business. To do this, a radical shift in the way they work with their data is needed. And no, we don’t mean Big Data. Lees meer
By now, most organizations have gotten their Big Data. And that is a problem. Not because we can’t accommodate Big Data, but because the more data you have, the harder it becomes to connect it and use it. We need to go beyond Big Data, towards Connected Data.
We’ll show how enterprises can use decentralized Knowledge Graphs to vastly increase the connectivity of their data, drawing on hard won experience of architecting and successfully delivering innovative technical projects for the world’s largest financial organisations.
Large enterprises that want to survive the AI tsunami must undergo a profound transformation in the way they think about their data. It starts by accepting that they need to link a large percentage of ALL their data together into a unified whole.
Achieving this will require a radical rethink of some established ideas about enterprise data integration. The truth is meaningful data doesn't exist in isolation; everything is positioned within the context of everything else.
That is why the future of data is graph shaped … but what are graphs and what is so great about them?
Knowledge Graphs are a really powerful tool, but on their own, they are not enough to transform enterprise data integration. We also need to get our heads around the complex idea of decentralisation. In a decentralised data mesh, the responsibility for data integration is pushed down to the individual applications.
Unbeknownst to most people, a third of all web pages now contain little islands of data that help the search engines build their knowledge graphs. Enterprises do not need to reinvent the wheel to build themselves a Decentralised Enterprise Knowledge Graph. They can …

Systems that learn and reason | Frank Van Harmelen
1 april 2024 · 28 min
After the amazing breakthroughs of machine learning (deep learning or otherwise) in the past decade, the shortcomings of machine learning are also becoming increasingly clear: unexplainable results, data hunger and limited generalisability are all becoming bottlenecks. Lees meer
In this talk we will look at how the combination with symbolic AI (in the form of very large knowledge graphs) can give us a way forward, towards machine learning systems that can explain their results, that need less data, and that generalise better outside their training set.

Novel AI Hardware Architectures for Graph Processing | Panel Discussion
4 maart 2024 · 1 uur 35 min
What do graphs have to do with novel hardware architectures for AI workloads? Lees meer
Graph processing is the key to unlocking new architectures, as much as new architectures can boost execution of graph-oriented workloads.
As machine learning-powered applications are proliferating, the workloads that are created in order to serve their requirements are taking up an ever increasing piece of the compute pie.
An IDC study found that Data Management, Application Development & Testing, and Data Analytics workloads represented more than half of all IaaS and PaaS spending already in 2018. IDC notes that this was driven in part by initial adoption of artificial intelligence and machine learning capabilities.
The rise of generative AI means that as adoption grows, data and AI workloads will dominate. This is why we see NVIDIA earnings skyrocket, as well as a renaissance of novel hardware architectures designed from the ground up to serve the needs of data and AI workloads.
More specifically for data analytics, understanding relationships among data points is a challenging but essential capability. Graph analytics has emerged as an approach by which analysts can efficiently examine the structure of the large networks and draw conclusions from the observed patterns. This is why DARPA set out to develop a graph analytics processor with the HIVE Project.
Furthermore, all machine learning models are best expressed as graphs. This is how machine learning libraries such as TensorFlow work. Efficient processing of graph-based networks involves large sparse data structures that consist of mostly zero values, and next generation architectures should avoid unnecessary processing.
This panel explores the interrelationship between graph processing and novel AI hardware architectures. Hosted by ZDNet's Tiernan Ray with panelists from some of the most groundbreaking AI hardware companies: Blaize, Determined AI / HPE, Graphcore, and SambaNova.

Graph Abstractions Matter | Ora Lassila
5 februari 2024 · 22 min
While mathematicians have used graph theory since the 18th century to solve problems, the software patterns for graph data are new to most developers. To enable "mass adoption" of graph technology, we need to establish the right abstractions, access APIs, and data models. Lees meer
RDF triples, while of paramount importance in establishing RDF graph semantics, are a low-level abstraction, much like using assembly language. For practical and productive “graph programming” we need something different.
Similarly, existing declarative graph query languages (such as SPARQL and Cypher) are not always the best way to access graph data, and sometimes you need a simpler interface (e.g., GraphQL), or even a different approach altogether (e.g., imperative traversals such as with Gremlin).

Ora Lassila is a Principal Graph Technologist in the Amazon Neptune graph database group. He has a long experience with graphs, graph databases, ontologies, and knowledge representation. He was a co-author of the original RDF specification as well as a co-author of the seminal article on the Semantic Web.

Taxonomies: Connecting Data with Duct Tape | Mike Dillinger
2 januari 2024 · 31 min
Taxonomies are the duct tape of connected data. They seem simple, flexible, and familiar. They are widely used. And they seem to work across many use cases and many domains. Lees meer
But when looked at in more detail, taxonomies turn out to be crude tools for knowledge organization that are very difficult to create, to scale, to adapt, to align, and to build on.
They don't work well for larger or more complex domains and use cases. Experienced talent and flexible tools for creating them are hard to find and to develop. Often taxonomies are built then abandoned for other, more robust approaches to knowledge organization.
It is essential to re-evaluate your connected data strategies in the context of alternative approaches to knowledge organization.

Graph Analytics vs Graph Machine Learning | Jörg Schad
5 juni 2023 · 29 min
Graph Analytics has long demonstrated that it solves real-world problems including Fraud, Ranking, Recommendation, text summarization and other NLP tasks. Lees meer
More recently, Graph Machine Learning applied directly on graphs using graph algorithms and machine learning, has been demonstrating significant advantages in solving the same problems as graph analytics as well as problems that are impractical to solve using graph analytics. Graph Machine Learning does this by training statistical models on the graph resulting in Graph Embeddings and Graph Neural Networks that are used to complex problems in a different way.
Jörg Schad, ArangoDB CTO, compares and contrasts these two approaches (spoiler: often complexity vs precision) in real-world scenarios. What factors should you consider when choosing one over the other and when do you even have a choice? Learn about exciting new developments in Graph ML and the graph techniques on which they are based.

1 mei 2023 · 2 uur 3 min
Are your personal data, documents, files and messages all over the place? Lees meer
Do you find yourself switching between applications, devices and files, unable to remember or find what you were looking for?
Would it make you feel better to know that it's not entirely your fault, and maybe there is a way out?
You know the stories about how the volume of data the world generates every day has gone through the roof. You know how most platforms want to lock you and your data in.
The volume and complexity of data each person has to manage today is comparable to what business owners and knowledge management professionals had to manage a few years ago.
What if each one of us could use the tools and practices professionals use to manage their data and build knowledge, while avoiding vendor lock-in?
A new generation of tools aiming to democratize access to knowledge management best practices and technology previously reserved for professional use is on the rise.
These tools, geared towards personal use, come in many shapes and forms. But they have one thing in common: they treat connections and context as first-class citizens, leveraging the graph paradigm.
Join us as we explore the rise of the Personal Knowledge Graph, and discuss use cases, tools, features and functionality, challenges and opportunities, and how to get started.
This panel will help define and explore the interplay between the most advanced technology for managing data and knowledge and user-oriented tools.

AI + Knowledge - a match made in heaven? | Panel Discussion
1 november 2021 · 1 uur 52 min
What does graph have to do with machine learning? Lees meer
A lot, actually. And it goes both ways
Machine learning can help bootstrap and populate knowledge graphs.
The information contained in graphs can boost the efficiency of machine learning approaches.
Machine learning, and its deep learning subdomain, make a great match for graphs. Machine learning on graphs is still a nascent technology, but one which is full of promise.
Amazon, Alibaba, Apple, Facebook and Twitter are just some of the organizations using this in production, and advancing the state of the art.
More than 25% of the research published in top AI conferences is graph-related.
Domain knowledge can effectively help a deep learning system bootstrap its knowledge, by encoding primitives instead of forcing the model to learn these from scratch.
Machine learning can effectively help the semantic modeling process needed to construct knowledge graphs, and consequently populate them with information.

To support ubiquitous AI, a Knowledge Graph system will have to fuse and integrate data, not just in representation, but in context (ontologies, metadata, domain knowledge, terminology systems), and time (temporal relationships between components of data).
Building from ‘Entities’ (e.g. Customers, Patients, Bill of Materials) requires a new data model approach that unifies typical enterprise data with knowledge bases such as industry terms and other domain knowledge.
Entity-Event Knowledge Graphs are about connecting the many dots, from different contexts and throughout time, to support and recommend industry-specific solutions that can take into account all the subtle differences and nuisances of entities and their relevant interactions to deliver insights and drive growth.
The Entity-Event Data Model we present puts core entities of interest at the center and then collects several layers of knowledge related to the entity as ‘Events’.
Franz Inc. is working with organizations across a broad range of industries to deploy large-scale, high-performance Entity-Event Knowledge Graphs that serve as the foundation for AI-driven applications for personalized medicine, predictive call centers, digital twins for IoT, predictive supply chain management and domain-specific Q&A applications—jus…

Does Connected Data need AI or AI need Connected Data | Panel Discussion
6 september 2021 · 38 min
Connected Data encompasses data acquisition and data management requirements from a range of areas including the Semantic Web, Linked Data, Knowledge Management, Knowledge Representation and many others. Lees meer
Yet for the true value of many of these visions to be realised both within the public domain and within organisations requires the assembly of often huge datasets. Thus far this has proven problematic for humans to achieve within acceptable timeframes, budgets and quality levels.
This panel discussion by Paul Groth, Spyros Kotoulas, Tara Rafaat, Freddy Lecue & moderator Szymon Klarman tackles these issues.

Κnowledge Architecture: Combining Strategy, Data Science and Information Architecture to Transform Data to Knowledge at NASA | David Meza
5 juli 2021 · 49 min
"The most important contribution management needs to make in the 21st Century is to increase the productivity of knowledge work and the knowledge worker", said Peter F. Drucker in 1999, and time has proven him right. Lees meer
Even NASA is no exception, as it faces a number of challenges. NASA has hundreds of millions of documents, reports, project data, lessons learned, scientific research, medical analysis, geospatial data, IT logs, and all kinds of other data stored nation-wide.
The data is growing in terms of variety, velocity, volume, value and veracity. NASA needs to provide accessibility to engineering data sources, whose visibility is currently limited. To convert data to knowledge a convergence of Knowledge Management, Information Architecture and Data Science is necessary.
This is what David Meza, Acting Branch Chief - People Analytics, Sr. Data Scientist at NASA, calls "Knowledge Architecture": the people, processes, and technology of designing, implementing, and applying the intellectual infrastructure of organizations.

Graph for Good: Empowering your NGO | Mario Bastande
3 mei 2021 · 32 min
May graph technology improve the deployment of humanitarian projects? The goal of using what we call “Graphs for good at Action Against Hunger” is to be more efficient and transparent, and this can have a crucial impact on people’s lives. Lees meer
Is there common behaviour factors between different projects? Can elements of different resources or projects be related? For example, security incidents in a city could influence the way other projects run in there.
The explained use case data comes from a project called Kit For Autonomous Cash Transfer in Humanitarian Emergencies (KACHE) whose goal is to deploy electronic cash transfers in emergency situations when no suitable infrastructure is available.
It also offers the opportunity to track transactions in order to better recognize crisis-affected population behaviours, understanding goods distribution network to improve recommendations, identifying the role of culture in transactional patterns, as well as most required items for every place.

Connecting People, Data, and Apps Without Centralization | Ruben Verborgh
6 april 2021 · 34 min
Big Data has transformed the world big time. It led many companies to strongly focus on data analytics, trying to collect and control gigantic amounts of data. After years in the rat race, several of them are slowly realizing that the continuous striving for having more data than others is maybe not the most meaningful business objective for everyone.

Knowledge Graphs and SEO: The next chapter | Panel Discussion
1 februari 2021 · 1 uur 56 min
“Knowledge Graph” is an overloaded term. Lees meer
Today Knowledge Graphs are becoming mainstream, and as this happens, more and more people associate Knowledge Graphs with data models, semantics, knowledge management, and ontologies
For many other people, however, Knowledge Graphs still mean Google Search Info Boxes, panels, SERPs, and SEO (Search Engine Optimization).
They are all right.
The term Knowledge Graph was introduced by Google to signify the huge improvement that semantic technology brought to its search engine.
Over time, the extended search capabilities and components enabled by semantic technology have become namesakes for Knowledge Graph.
While the term Knowledge Graph has more meanings than this, it’s useful to return to the source.
The evolution of Knowledge Graph-powered Google search now extends to voice, assimilates information from JSON-LD markup beyond Wikipedia, and advances the state of the art in NLP (Natural Language Processing).
Let’s explore how this influences, and is influenced by, advances in semantic technology, where the evolution of SEO is headed, and what this means for knowledge graphs at large.

One Ontology, One Data Set, Multiple Shapes with SHACL | Tara Raafat
7 september 2020 · 31 min
Data integration, data interoperation and data quality are major challenges that continue to haunt enterprises. Every enterprise either by choice or by chance has created massive silos of data in different formats, with duplications and quality issues. Lees meer
Knowledge graphs have proven to be a viable solution to address the integration and interoperation problem. Semantic technologies in particular provide an intelligent way of creating an abstract layer for the enterprise data model and mapping of siloed data to that model, allowing a smooth integration and a common view of the data.
Technologies like OWL (Web Ontology Language) and RDF (Resource Description Framework) are the back bone of semantics for knowledge graph implementation. Enterprises use OWL to build an ontology model to create a common definition for concepts and how they are connected to each other in their specific domain.
They then use RDF to create a triple format representation of their data by mapping it to the Ontology. This approach makes their data smart and machine understandable.
But how can enterprises control and validate the quality of this mapped data? Furthermore, how can they use this one abstract representation of data to meet all their different business requirements? Different departments, different LoBs and different business branches all have their own data needs, creating a new challenge to be tackled by the enterprise.
In this talk we will look at how the power of SHACL (SHAPES and Constraints Language), a W3C standard for defining constraint sets over data; complements the two core semantic technologies OWL and RDF. What are the similarities, the overlaps and the differences.
We will talk about how SHACL gives enterprises the power to reuse, customize and validate their data for various scenarios, uses cases and business requirements; making the application of semantics even more practical.

Knowledge graphs, meet Deep Learning | Andy Jefferson
3 augustus 2020 · 33 min
Knowledge graphs generation is outpacing the ability to intelligently use the information that they contain. Octavian's work is pioneering Graph Artificial Intelligence to provide the brains to make knowledge graphs useful. Lees meer
Our neural networks can take questions and knowledge graphs and return answers.
Imagine:
a google assistant that reads your own knowledge graph (and actually works)
a BI tool reads your business' knowledge graph
a legal assistant that reads the graph of your case
Taking a neural network approach is important because neural networks deal better with the noise in data and variety in schema. Using neural networks allows people to ask questions of the knowledge graph in their own words, not via code or query languages.
Octavian's approach is to develop neural networks that can learn to manipulate graph knowledge into answers. This approach is radically different to using networks to generate graph embeddings. We believe this approach could transform how we interact with databases.
Prior knowledge of Neural Networks is not required and the talk will include a simple demonstration of how a Neural Network can use graph data.
About the speaker: Andy Jefferson believes that graphs have the potential to provide both a representation of the world and a technical interface that allows us to develop better AI and to turn it rapidly into useful products. Andy combines expertise in machine learning with experience building and operating distributed software systems and an understanding of the scientific process. Before he worked as a software engineer, Andy was a chemist, and he enjoys using the tensor algebra that he learned in quantum chemistry when working on neural networks.

Graphs in Sustainable Finance | James Phare
15 juli 2020 · 41 min
In recent years graphs have been increasingly adopted in financial services for everything from fraud detection to Know Your Customer (KYC) to regulatory requirements. Lees meer
At the same time Environmental Social Governance (ESG) investing has become the fastest growing segment of financial services.
In this session James Phare, Neural Alpha CEO and Founder, discusses how many of these historical graph techniques are now being enhanced for the era of sustainable investing.
Going beyond definitions, let's identify use cases, discuss news and trends, and wrap up with an ask me anything session.
Graph Databases have been rapidly adopted within financial services since 2008 financial crisis as regulatory drivers have mandated Banks, Asset Managers and others to ramp up efforts to understand their customers better (KYC), report to regulators more precisely in areas such as data lineage and prevent fraud and sanctions breaches. In recent years there has also been a trend towards a ‘greening’ of financial services driven partly by regulators but also by a new generation of financial consumers demanding investments that no longer damage the environment or society at large. Environmental Social Governance (ESG) investing is now the fastest growing segment of the Fund Management industry with the number of funds growing 80% since 2012 to now exceed $1.8tn in assets.
In this talk James discusses what he’s been up to recently in his day job as CEO of Neural Alpha – a sustainable fintech based in London. He will give an overview of why he sees graphs as an essential part of the technologists’ toolkit for making the financial industry more sustainable, some of the challenges in large scale, graph centric data integration projects and some of the unique analyses possible from leveraging the power of the graph.
James will give a deep dive into how the team are using graph technology to develop tools for the financial industry to more thoroughly screen investments and develop new pr…

The Years of the Graph: The Future of the Future is here | George Anadiotis
8 juli 2020 · 29 min
What is graph all about, and why should you care? Graphs come in many shapes and forms, and can be used for different applications: Graph Analytics, Graph AI, Knowledge Graphs, and Graph Databases. Lees meer
Up until the beginning of the 2010s, the world was mostly running on spreadsheets and relational databases. To a large extent, it still does. But the NoSQL wave of databases has largely succeeded in instilling the “best tool for the job” mindset.
After relational, key-value, document, and columnar, the latest link in this evolutionary proliferation of data structures is graph. Graph analytics, Graph AI, Knowledge Graphs and Graph Databases have been making waves, included in hype cycles for the last couple of years.
The Year of the Graph marked the beginning of it all before the Gartners of the world got in the game. The Year of the Graph is a term coined to convey the fact that the time has come for this technology to flourish.
The eponymous article that set the tone was published in January 2018 on ZDNet by domain expert George Anadiotis. George has been working with, and keeping an eye on, all things Graph since the early 2000s. He was one of the first to note the continuing rise of Graph Databases, and to bring this technology in front of a mainstream audience.
The Year of the Graph has been going strong since 2018. In August 2018, Gartner started including Graph in its hype cycles. Ever since, Graph has been riding the upward slope of the Hype Cycle.
The need for knowledge on these technologies is constantly growing. To respond to that need, the Year of the Graph newsletter was released in April 2018. In addition, a constant flow of graph-related news and resources is being shared on social media.
To help people make educated choices, the Year of the Graph Database Report was released. The report has been hailed as the most comprehensive of its kind in the market, consistently helping people choose the most appropriate solution for their use case since 2018.

From Semantics and SEO to Knowledge Graphs, and Back Again | Panel Discussion
1 juli 2020 · 28 min
Knowledge graphs are all the rage these days, but for many they are still an exotic notion which is hard to come to terms with. In this panel, experts who have been working with knowledge graphs before it was cool will share their experience. Lees meer
More specifically, we’ll be looking into the interplay between semantics, SEO, schema.org, JSON-LD, and knowledge graphs.
Though it may not be obvious, if you are doing SEO today, you are working with knowledge graphs. Ever since Google popularized the notion of knowledge graphs, it’s been things, not strings. The “things” that search engines can understand are all in schema.org, which is, you guessed it, a framework for building knowledge graphs.
Semantic SEO experts Jono Alderson and Andrea Volpini, and expert knowledge graph builder Panos Alexopoulos will share how to onboard yourself to knowledge graphs via schema.org and JSON-LD, as well as the specifics of working with these technologies, and how they can be used to kick-start your own knowledge graphs.
We’ll also look at the other direction in this equation: how you can use your knowledge graphs to boost your SEO. Last but not least, we will examine the evolution of schema.org

A 2020 Semantic Web vision for the real world | Panel Discussion
1 juli 2020 · 58 min
David Amerland, George Anadiotis, Panos Alexopoulos, and Teodora Petkova, have a few things in common. Besides being successful professionals, each in their own way, they also share a passion not many people share: the Semantic Web. As the Semantic Web is turning 20, they come together to talk about the passion. Lees meer
The first rule of the Semantic Web in the 2020's is, you don't talk about the Semantic Web. Most people don't. For most people, the Semantic Web is something they may be vaguely familiar with, and perhaps something that has been tried, and failed. Truth is, you may not know it, but you use the Semantic Web every day, and you love it.
The Semantic Web, soon to celebrate its 20th anniversary, may not enjoy the kind of universal acclaim the WWW got on its 30th birthday, although both were kickstarted by Tim Berners Lee. It does, however, underpin Knowledge Graphs, and in that sense, it is in its heyday. We have known, loved, and used the Semantic Web for a long time, and we'll share why we think you should, too.

Connecting data, decentralizing the web, making it sustainable: can the semantic web do this? | Panel Discussion
4 mei 2020 · 42 min
Whether we call it Semantic Web or Linked Data, Tim Berner Lee’s vision never really caught on among users and developers. Although part of this vision is about decentralization, and this is something a few people are working on, Semantic Web technology remains largely underutilized by them. In this panel, we will explore how the Semantic Web and decentralization can benefit each other. Lees meer
Getting together people from both communities, and exploring questions such as:
Is the Semantic Web technological stack really as complex as it is perceived to be? How can it be made more accessible, and align better with today’s realities in software development?
What are the issues facing people working in decentralization, and how could Semantic Web technology provide solutions?
What about sustainability? How can efforts aiming to provide services to the public at large find a way to sustain themselves, navigating a challenging business landscape?

Facilitating COVID-19 research with Graph Analytics and Knowledge Graphs
27 april 2020 · 53 min
Scientists, health researchers and policymakers are using all the tools they can get their hands on to try and beat the current global pandemic. Lees meer
Germany’s National Centre for Diabetes Research (DZD) is one of the organizations turning to Artificial Intelligence, advanced visualisation techniques and other tools to aid the search for a vaccine and effective treatments.
Graph technology is key in this effort. DZD is integrating data from various sources and linking them in a dedicated COVID-19 Knowledge Graph to help researchers and scientists quickly and efficiently find their way through the more than 40,000 publications out there on the problem.
DZD's Head of Data Management and Knowledge Management, Dr. Alexander Jarasch, notes that, “Graph enables a new dimension of data analysis by helping us to connect highly heterogeneous data from various disciplines.”
The COVID GRAPH project is a voluntary initiative of graph enthusiasts and companies with the goal to build a knowledge graph with relevant information about the COVID-19 virus. It's a knowledge graph on COVID-19 that integrates various public datasets. This includes relevant publications, case statistics, genes and functions, molecular data and much more.
Still, the global scientific knowledge base is little more than a collection of documents. It is written by humans for humans, and we have done so for a long time. This makes perfect sense, after all it is people that make up the audience, and researchers in particular.
Yet, with the monumental progress in information technologies over the more recent decades, one may wonder why it is that the scientific knowledge communicated in scholarly literature remains largely inaccessible to machines. Surely it would be useful if some of that knowledge is more available to automated processing.
The Open Research Knowledge Graph (ORKG) project is working on answers and solutions. The project, recently initiated, and coordinated by TIB (Leibniz Information Centre…

In Search of the Universal Data Model | Joshua Shinavier
2 april 2020 · 32 min
For as long as people have been thinking about thinking, we have imagined that somewhere in the inner reaches of our minds there are ghostly, intangible things called ideas which can be linked together to create representations of the world around us — a world that has a certain structure, conforms to certain rules, and to a certain extent, can be predicted and manipulated on the basis of our ideas. Lees meer
Rationalist philosophers have struggled for centuries to make a solid case for this intuitive, almost inborn view of human experience, but it is only with the advent of modern computing that we have the opportunity to build machines which truly think the way we think we think.
For the first time, we can give concrete form to our mental representations as graphs or hypergraphs, explicitly specify our mental schemas as ontologies, and formally define the rules by which we reason and act on new information. If we so choose, we can even use these human-like building blocks to construct systems that carry far more information than any single human brain, and that connect and serve millions of people in real time.
As enterprise knowledge graphs become increasingly mainstream, we appear to be headed in that direction, although there is no guarantee that the momentum will continue unless actively sustained. Where knowledge graphs are likely to be the most essential, in the long run, is at the interface between human and machine; mental representation versus formal knowledge representation.
In this talk, we will take a step back from the many practical and social challenges of building large-scale knowledge graphs, which at this point are well-known. Instead, we will take up the quest for an ideal data model for knowledge representation and data integration, seeking common ground among the most popular data models used in industry and open source software, surveying what we suspect to be true of our own inner models, and previewing structure and process in Apache TinkerPop, …

Graph Databases Will Rule the World in the 2020s. But Why, and How? | Panel Discussion
24 maart 2020 · 25 min
Some of us may have been saying that for years, but now the Gartners of the world are picking up on it too. So, the oracles have spoken: Lees meer
“The application of graph processing and graph DBMSs will grow at 100 percent annually through 2022 to continuously accelerate data preparation and enable more complex and adaptive data science”.
That all sounds great, in theory. In practice, however, things are messy. If you’re out to shop for a graph database, you will soon realize that there are no universally supported standards, performance evaluation is a dark art, and the vendor space seems to be expanding by the minute.
Recently, the W3C initiated an effort to brings the various strands of graph databases closer together, but it’s still a long way from fruition.
So, what’s all the fuss about? What are some of the things graph databases are being used for, what are they good at, and what are they not so good at?
Property graphs and RDF are the 2 prevalent ways to model the world in graph; What is each of these good at, specifically? What problems does each of these have, and how are they being addressed?
RDF* is a proposal that could help bridge graph models across property graphs and RDF. What is it, how does it work, and when will it be available to use in production?
What about query languages? In the RDF world, SPARQL rules, but what about property graphs? Can Gremlin be the one graph virtual machine to unite them all?
What about the future of graph databases? Could graph turn out to be a way to model data universally?
