Don't miss Marple & classification with Solr

Mar 23, 2017 · Greater London, United Kingdom

We're back with another Meetup! This time the Flax team are going to present a project we've been working on for a while, a RESTful API for Lucene index inspection - Marple.

Our second talk is from Alessandro Benedetti, a Search Consultant and R&D Software Engineer at Sease Ltd., on Classification with Solr. His focus is on information retrieval, information extraction, natural language processing, and machine learning. When he isn't on client projects, he is actively contributing to the open source community.

This presentation will start by introducing how Apache Lucene can be used to classify documents using data structures that already exist in your index instead of having to generate and supply external training sets. The focus will be on extensions of the Lucene Classification module that come in Lucene 6.0 and the Lucene Classification module's incorporation into Solr 6.1. These extensions will allow you to classify at a document level with individual field weighting, numeric field support, lat/lon fields etc. The Solr ClassificationUpdateProcessor will be explored and how to use it including basic and advanced features like multi class support and classification context filtering. The presentation will include practical examples and real world use cases.

Barclays have kindly offered to host in their Canary Wharf building - we'll be in Plaza Room 9. Please note that there will be no food or drink in the meeting room itself, but we will organise a meal or pub snacks somewhere else afterwards (probably in the Tea Merchant).,

Please note we will starting as soon as possible after 6pm - don't be late!

You *must* supply your real name when RSVPing for Barclays security.
