Most of the members of the Working Group data Retrieval and Evaluation (WG R&E) are patent information professionals involved in the day-to-day business of information retrieval and evaluation. The activities of the working group are exchanging experiences in the use and quality of databases, searching, internet, and supporting software. The working group aims to provide a forum for information professionals to meet and actively share ideas and experiences on this. This is done in dedicated Task Forces and WG meetings hosted by one of the member companies. External speakers are invited to give focused presentations and are consulted as dialogue partners. The WG R&E organises various inter-company tests, comparisons and evaluation studies and the results are presented to the members and information providers concerned objectively. This approach has proved to be very effective for drawing attention to the needs of information professionals in industry.
