That's AMAZING! I was just thinking about using Neo4j to store some extracted n-grams, I previously did it with a SQLite database but maybe using a graph an application could surf between nodes more efficiently. One question: is it possible to download the google ngram corpus release (or at least

[Neo4j] collation and wild card queries

If you were doing this in a single traversal, every time you encountered a node type C, you would have to ask for all it's relationships and dig inside the end node of those relationships to see if any of them have a property type for node B. In two traversals, you'd get an array of all the Cs
