Title: Welcome to the Open Relevance Project URL: openrelevance/index.html save_as: openrelevance/index.html template: lucene/openrelevance/index

The Open Relevance Project (ORP) was a small Apache LuceneTM sub-project aimed at making materials for doing relevance testing for Information Retrieval (IR), Machine Learning and Natural Language Processing (NLP) into open source.

Our initial focus was on creating collections, judgments, queries and tools for the Lucene ecosystem of projects (Lucene Java, SolrTM, NutchTM, MahoutTM, etc.) that can be used to judge relevance in a free, repeatable manner.

The Apache Lucene Project Management Committee decided in a vote, that the Apache Lucene sub-project “Open Relevance” will be discontinued.
