Laurent Romary and Patrice Lopez: CLEF-IP winners 2010

For the second year in succession, Laurent Romary and Patrice Lopez have won the CLEF-IP information retrieval competition.

Their search system, PATATRAS (PATent and Article Tracking, Retrieval and AnalysiS), did not let them down, placing them far ahead of the other participating research teams.

Created in 2009 by the Information Retrieval Facility (Vienna, Austria), CLEF-IP is one of the competitions held as part of the CLEF conference (Conference on Multilingual and Multimodal Information Access Evaluation). The competition evaluates large-scale indexing and information retrieval techniques in multilingual collections of patent documents. The aim is to automate prior art searches by patent examiners with a view to refusing, revoking or restricting a patent.

The CLEF-IP 2010 document repository contains some 2.6 million documents corresponding to all of the patent applications made to the European Patent Office up until 2002 in three languages (English, French and German). The prior art search was made on a set of 2,000 documents.

Ranked first out of a total of nine participants this year, Laurent Romary and Patrice Lopez also won the competition last year, when 14 teams took part.

This kind of search is designed not only to analyse patent information, but also to help engineers and researchers to cope with the vast quantities of scientific and technical information available. One of the aims of eScience is to achieve a degree of automation of experimentation data and text mining techniques that makes it possible to automatically propose pertinent new scientific hypotheses and potentially innovative technical approaches.
