摘要:Search engines are the most commonly used type of tool for finding relevant information on the Internet. However, today's search engines are far from perfect. Typical search queries are short, often one or two words, and can be ambiguous therefore returning inappropriate results. A precise search engine adapted to professional environments which are characterized by a domain (e.g. medicine, law, sport, and so on). In our approach, each domain has its own terminology (i.e. a set of terms that denote its concepts: team, player, etc.) and it is organized along dimensions, such as person, location, etc. The dimensions, as described below, are made of concepts and semantic relationships. that represent a particular persp ective or point of view on the domain. We mainly use the notion of domain dimension to: i) precisely index document co ntent, and ii) develop an interactive interface which allows the user to precisely describe his or her information need and therefore precisely access the document collection. These evaluation initiatives have led to a considerable increase in system performance. Data for evaluation efforts include multilingual corpora, structured data, scientific documents, Web pages as well as multimedia objects. This paper gives an overview of the current activities of the major evaluation initiatives. Special attention is given to the current track s and developments within TREC, CLEF and NTCIR. The evaluation tasks and issues, as well as some results, will be presented
