title = "Dynamic Facet Hierarchy constructing for Browsing web search results Efficiently",
abstract = "In this paper, a method is proposed to dynamically construct a faceted interface to help users navigate web search results for finding required data efficiently. The proposed method consists of two processing steps: 1) candidate facets extraction, and 2) facet hierarchy construction. At first, the category information of entities in Wikipedia and a learning model are used to select the query-dependent facet terms for constructing the facet hierarchy. Then an objective function is designed to estimate the average browsing cost of users when accessing the search results by a given facet hierarchy. Accordingly, two greedy based algorithms, one is a bottom-up approach and another one is a top-down approach, are proposed to construct a facet hierarchy for optimizing the objective function. A systematic performance study is performed to verify the effectiveness and the efficiency of the proposed algorithms.",
