NLP Knowledge Graph Tutorial

I'm going through the tutorial at Tutorial: Build a Knowledge Graph using NLP and Ontologies - Developer Guides

Once I get to slide 15 I'm getting a no changes, no records. Possibly something to do with HAS_ENTITY? Any help appreciated thanks:

MATCH (c:Category {name: "NoSQL database management system"})
CALL n10s.inference.nodesInCategory(c, {
inCatRel: "ABOUT",
subCatRel: "SUB_CAT_OF"
YIELD node
MATCH (node)<-[:HAS_ENTITY]-(article)
RETURN article.uri AS uri, article.title AS title, article.datetime AS date,
collect(n10s.rdf.getIRILocalName(node.uri)) as explicitTopics

  • neo4j desktop version 1.4.8
  • which plugins / extensions / procedures do you use: APOC, n10s


Please install GDS plugin that is compatible with desktop version that you have installed.

Thanking you

Also install neosemantics 10s plugin
and load RDF Taxonomy into Project DB engine. After that you can use sparkle Query to extract RDF triplets (documents from Marklogic). But may be you will need to apply transformation logic of your own embedded inside a plugin to achieve whatever your goal is.

Thanking you
