Search Relevance is my favorite topic to focus upon within the search and information retrieval domain. As such, I was elated when I found out that the team at Open Source Connections was putting together a conference this year called “Haystack” focused entirely on Relevance. I was honored to be invited to talk on the topic of “The Relevance of the Apache Solr Semantic Knowledge Graph.” If you’ve heard me present before on the Semantic Knowledge Graph, you’ll know that it is a really powerful tool for driving semantic understanding within search results. It was great getting to talk with some many like-minded relevance practitioners at Haystack, and to be able to share the below presentation with them, as well.
