document: Personalized interactive faceted search Faceted search is becoming a popular method to allow users to interactively search and navigate complex information spaces . A faceted search system presents users with key-value metadata that is used for query refinement . While popular in e-commerce and digital libraries , not much research has been conducted on which metadata to present to a user in order to improve the search experience . Nor are there repeatable benchmarks for evaluating a faceted search engine . This paper proposes the use of collaborative filtering and personalization to customize the search interface to each user 's behavior . This paper also proposes a utility based framework to evaluate the faceted interface . In order to demonstrate these ideas and better understand personalized faceted search , several faceted search algorithms are proposed and evaluated using the novel evaluation methodology .
