- Abstract
- In this paper, we present Dynamic Category Sets, a novel approach that addresses the vocabulary problem for faceted data. In their paper on the vocabulary problem, Furnas et al. note that "the keywords that are assigned by indexers are often at odds with those tried by searchers." Faceted search systems exhibit an interesting aspect of this problem: users do not necessarily understand an information space in terms of the same facets as the indexers who designed it. Our approach addresses this problem by employing a data-driven approach to discover sets of values across multiple facets that best match the query. When there are multiple candidates, we offer a clarification dialog that allows the user to disambiguate them.

- 1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).
