Welcome to the Open Relevance Project
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.

25 June 2009 - Apache Open Relevance Kickoff ¶
The Apache Lucene PMC has officially voted to add the Open Relevance Project (ORP) as a Lucene subproject. ORP's main goal is to build out collections, judgments and queries in an open environment to make it easier for Lucene developers and users to do relevance testing, much like one would get if using TREC or other evaluation conferences.
