EntEXPO: An Interactive Search System for Entity-Bearing Queries

The paper presents EntEXPO, a search system that aims to improve the search experience for entity-bearing queries. In particular, the system exploits the entities and their relations in the context of query to identify a list of related entities and leverage them in an entity-centric query expansion method to generate more effective search results. Moreover, EntEXPOi¾?displays the related entities along with the search results to allow search users explore entity relationship to further refine the query through an interactive interface.
