Fundamentally, you must create a schema representing your corpus of data (from any domain), send the corpus of documents to Solr (script to do this is included), and then you can send queries to the Semantic Knowledge Graph request handler to discover and/or score relationships. This talk will describe how to overcome this by leveraging Lucene/Solr to power a knowledge graph that can extract phrases, understand and weight the semantic relationships between those phrases and known entities, and expand the query to include those additional conceptual relationships. In this talk, we'll do a deep dive into the internals of how the Semantic Knowledge Graph works and will walk you through how to get up and running with an example dataset to explore the meaningful relationships hidden within your data.
