Abstract
Techniques are provided for creating and updating a entity hierarchy (taxonomy) based on information captured about user interaction with a system. Techniques are also provided for using the taxonomy to determine the nature of entities represented by terms submitted to a search engine. Search logs analyzed for related sets of entities, and used to improve the taxonomy for storing information. Once the taxonomy is created, information across data sources are fetched and aggregated based on the taxonomy. When the system is queried, the query is modified to a predefined template, and the best fit result is promptly returned. A feedback mechanism is also provided to enhance taxonomy and entity data based on search volumes. This system enables search engines to provide accurate answers when entities, their attributes and relationships are involved.
