Facebook Graph Search with Cypher and Neo4j | Max De Marzi

January 31st, 2013

Facebook Graph Search has given the Graph Database community a simpler way to explain what it is we do and why it matters. I wanted to drive the point home by building a proof of concept of how you could do this with Neo4j. However, I don’t have six months or much experience with NLP (natural language processing). What I do have is Cypher. Cypher is Neo4j’s graph language and it makes it easy to express what we are looking for in the graph. I needed a way to take “natural language” and create Cypher from it. This was going to be a problem.

The article is an interesting introduction to treetop (a “language for describing languages” used in Semr, a “framework to [support] natural language processing”) and how Mr. De Marzi uses it to create a simple Facebook Graph-like search using Neo4j. Very slick.

How Google and Facebook are using R : Dataspora Blog

May 12th, 2009

I’m a little behind the times, but I just saw this posting of how Google and Facebook are using R, my favorite new tool: How Google and Facebook are using R : Dataspora Blog. From the CRAN network to the easy chart/graph construction, R makes data analysis dangerously easy. Maybe too easy??? I mean, all those formulae have to mean something, right? I just scratch the surface of R with my tinkering, but it is clearly a very potent tool for crunching lots of numbers. And who has more data to crunch than Google? I mean, with a database called “Big Table” who doubts that they’re the biggest brother on the block.

Anyway, I plan on using R more and more in the coming months. Maybe I’ll be able to hear more about how Google is using it, too.
