bergis universe of software, hardware and ideas

Many blog articles and LinkedIn posts claim that Knowledge Graphs and Language Models are a good match and that potential future products that combine both worlds will be even more powerful. I work in that field because I strongly believe in that idea, but it requires more than a blog post with theoretical claims to convince people. That’s why I wrote this blog post with easy-to-understand examples that will work in the upcoming 8.2 release of TopBraid EDG and only require a basic understanding of SPARQL, JavaScript, and SHACL. If I haven’t sparked your interest yet, let me tell you that everything will be explained based on examples with wombats!

Knowledge Graphs combined with modern language models is still a hot topic. We have seen many demos in the past, and increasingly, they have become features in products, but most of the time, they are connected inefficiently. In this blog post, I will take a closer look at the essential building blocks of both worlds, their features, what makes them unique, and how they could be combined on a native level.

I hoped the “Leaving the Sinking Zazuko Ship” blog post would be the last post about Zazuko, but then they stole my code.

While working on RDF/JS specifications, I fulfilled two roles.

As the chair, I had the goal that every feasible requirement submitted could be implemented based on what is written in the specification.

Being the author and maintainer of RDF-Ext, I contribute requirements to the group as well. In this blog post, I want to provide you with a closer look at one core idea I pushed forward - an idea that, until now, was spread over multiple discussions and comments on different GitHub issues.

After almost 9 years, I left Zazuko, the company I co-founded, for good at the end of June. Like I share my open-source libraries with you, I was hoping you could benefit from the lesson I learned about how a dark triad personality ruined a company.

Graph traversing with plain RDF/JS objects is no fun. Keeping track of the path walked while traversing a graph adds another layer of complexity. With Grapoi, graph traversing is fun again and makes code more readable.

I guess it was not only my social media stream that was flooded with GPT4 news in the last few days. The results are impressive but not surprising to me. A combination of events, which are more important from my point of view, didn’t get that much attention: The LLM LLaMA runs on a Raspberry Pi, and Stanford students fine-tuned the model for $100.

This year, RDF-Ext will turn ten years old. In this blog post, I will give a brief overview of recent updates, show the current plans, and explain how you can help improve RDF-Ext.

One of my projects encountered a performance problem with the available SHACL engines. Besides, I needed to know which triples had been processed (coverage/fragments), so I implemented a new SHACL engine in JavaScript from scratch.

In my last blog post, I wrote about how to detect LLM output, with the conclusion that machine-learning approaches are not the solution. Today I want to show how the recent news “Man beats machine at Go in human victory over AI” is related to that topic.
