Evaluating Information Retrieval Techniques in the Intellectual Property Domain

After an interesting and rewarding first year, the Intellectual Property evaluation campaign (CLEF-IP) continues in 2010 as a benchmarking activity of the forthcoming "Conference on Multilingual and Multimodal Information Access Evaluation", CLEF 2010.


The main goals of the CLEF-IP campaign are to create a large test collection of multi-lingual European patents and to evaluate retrieval techniques in the patent domain.

This year, CLEF-IP puts to use a collection of almost 2 million patent documents in XML format with text in English, German, and French.
The track contains two tasks:

  • Prior Art Candidate Search: find patent documents that are likely to constitute prior art to a given patent application
  • Classification: classify a given patent document according to the IPC and/or ECLA classification schemes

Participants are invited to apply their favourite retrieval method and/or classifier on given sets of topics and submit their results. Relevance assessment will be done using patent citations for the first task and current patent classifications for the second task.
