User interactions with search engines reveal three main underlying intents, namely <i>navigational, informational</i>, and <i>transactional.</i> By providing more accurate results depending on such query intents the performance of search engines can be greatly improved. Therefore, query classification has been an active research topic for the last years.(More)
One of the most important issues in Information Retrieval is inferring the intents underlying users' queries. Thus, any tool to enrich or to better contextualized queries can proof extremely valuable. Entity extraction, provided it is done fast, can be one of such tools. Such techniques usually rely on a prior training phase involving large datasets. That(More)
One of the main interests in the Web Information Retrieval research area is the identification of the user interests and needs so the search engines and tools can help the users to improve their efficiency. Some research has been done on automatically identifying the goals of the queries the user submits, but it is usually based in semantic or syntactic(More)
Search engines are nowadays one of the most important entry points for Internet users and a central tool to solve most of their information needs.
