Neo4j: Building a topic graph with Prismatic Interest Graph API by Mark Needham.
From the post:
Over the last few weeks I’ve been using various NLP libraries to derive topics for my corpus of How I met your mother episodes without success and was therefore enthused to see the release of Prismatic’s Interest Graph API.
The Interest Graph API exposes a web service to which you feed a block of text and get back a set of topics and associated score.
It has been trained over the last few years with millions of articles that people share on their social media accounts and in my experience using Prismatic the topics have been very useful for finding new material to read.
…
A great walk through from accessing the Interest Graph API to loading the data into Neo4j and querying it with Cypher.
I can’t profess a lot of interest in How I Met Your Mother episodes but the techniques can be applied to other content. 😉
