I wrote a blog post on the HNSW vector index design, perhaps the most popular vector index design adopted by databases at this point. The post is based on several lectures I gave in a graduate course at UWaterloo last fall. This is intended

I think having a version with a sample synthetic dataset makes sense.

That's correct though OWL also provides ways to constraint what can be encoded (e.g., the cardinality constraint example I gave). But yes, SHACL is primarily for constraints. I general, there are several other standards than RDFS and O

I wrote a blog post on something that I find is often misunderstood and under-appreciated: Resource Description Framework (RDF). I explain what RDF is, what it is not, when you may need it, and its virtues and vices. RDF is good to know abo

I think even on the LLMS + KGs space the depth is not very deep. In fact there is more technical depth in the text-to-SQL than anything else I have seen on LLMs. Maybe the COLBERT-like matrix-models is another topic where there is good tech

For entity extraction you can look at SpanMarker: https://tomaarsen.github.io/SpanMarkerNER/ . I'm sure other tools exists and others can hopefully point at more.

This is a post that summarizes some reading that I had done in the space of LLMs + Knowledge Graphs with the goal of identifying technically deep and interesting directions. The post cover retrieval augmented generation (RAG) systems that u

You seem to have done some research already but let me answer briefly: GNNs and what I covered in the blog post, "RAG over structured data", are not connected. They are approaches to solve 2 different problems. GNNs: Let's fo

This is the first blog post on a series of posts I plan to write on the role graph DBMSs and knowledge graphs play on LLM applications and recent text-to-high-level-query-language work I read up on over the holiday season. These blogs have

I might be wrong in the numbers as I just got them from Wikipedia. But to be clear: Istanbul is the name of both the city and the "province" in Turkiye. And I used the larger area number from Wikipedia, which is for the province:

This is a good point. There must be one though that other cities can look up to. I would guess Singapore does a good job on these problems. I would be curious to hear of the best examples of large cities that have done a better job on housi

I am also amused that Ontario, which is the most populous province has the following statistics: Area: 1,076,395 km square Population: 15.3M Istanbul, which is the biggest city in my home country Turkiye has these: Area: 5,343 (so 200x smal

I've been living in Canada for 8 years and I generally heard people referring to "35M people", which I believe will soon change to "40M" people. Interesting that there is apparently a population clock that model&#x2

I remember the Brown prof's demo video, which was about a paralyzed person drawing a circle on the screen. The way it was implemented was by capturing and learning the signals the brain sends (but unable to send to the spine of course)

About 15 years ago I had seen a paralyzed man control mouse and computer interfaces (was research from Brown university). This is a new step where the translated brain signals are controlling the spine directly! This is truly amazing, inspi
