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 i…

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 gen…

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…

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-…

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 po…

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 …

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 …

RIP the greatest Colombian artist of all time.

"More than 150 people were involved in efforts to save caver Mark Dickey after he developed stomach problems in the Morca Cave on 2 September. Organisers say it was one of the larg…

Found this interesting article from this news article: https://phys.org/news/2023-07-aftermath-china-survey-chinese...

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 …

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 e…

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 …

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 apparentl…

I think this article isn't very stimulating but here's a good summary of the case made by many "realists" about international relations on why Ukraine's entry into NATO and the US-…
