Combining WordNet and ConceptNet in Neo4j

WordNet and ConceptNet are two popular databases of words and concepts that are used in a number of AI applications. This post will look at how we can combine the two of them into one searchable graph using Neo4j.

Before I start, some people may view this as a redundant task because ConceptNet already ingests WordNet, so why not just stick with loading ConceptNet into Neo4j?

While this is true, WordNet models its relationships at the synset level, while ConceptNet seeks to undo this (https://github.com/commonsense/conceptnet5/wiki/FAQ). This exercise is to combine both these types of abstractions into one large graph that we can use, allowing us to create graph queries against either network, or create queries that can combine both.

The rest of this post will give a quick overview of WordNet and ConceptNet, the graph model I’ve developer so far, a python script that will generate some import files for Neo4j, and finally some example cypher queries. For those just interested in the python script, you can find it at https://github.com/tomkdickinson/wordnet_conceptnet_neo4j.
