ENRICH: A Query Rewriting Service Powered by Wikipedia Graph Structure

The search for relevant information in websites can be very frustrating for users who, unintentionally, use too general or inappropriate keywords to express their requests. To overcome this situation, query rewriting techniques aim at transforming the users requests to better describe the real intent of the users. However, to the best of our knowledge, current search tools either are too generic or require resources not available for everyone such as query log processors, natural language engines, etc. To supply this need, we present ENRICH, which is a query rewriting cloud service that is automatically tailored to each website and it is powered by an available, accessible and open resource: Wikipedia.
