1 IntroductionThe most popular and basic techniques for accessing the Web are browse and search.Faceted search, also called faceted navigation or faceted browse, is a third technique thatenables users to access Web pages from different facets. A faceted search system can displaydifferent facets of the same set of Web pages at different steps in a search. Faceted search isalso a way to deal with the size of Web contents since it can locate the sought for contentthrough multi-step refinements on classifications from multiple facets [2, 5, 9]. Facetedsearch has been adopted in many applications such as e-learning, e-business, online library,and general search engines. However, research on its fundamental theory is neglected. Manyimportant problems are still open, such as the underlying theory for organizing resourcesfrom multiple dimensions, the generation of appropriate interactive query process, andadaptive interfaces. Research on the fundamental model and associated theory is criticalfor the development of faceted search.Classification and link are the most basic intelligent mechanisms for managing objectsand structuring space. Making use of classification and link is the natural way to manageWeb resources. Multi-dimensional classifications, called Resource Space Model, have beenused to manage various resources [13–16]. It is the theory, model and method that canorganize Web resources for faceted navigation.Classifications form and evolve with the evolution of society. Humans use words toindicate classifications to realize effective interaction [12]. Manually classifying Web re-sources is a straightforward approach to organize resources for faceted navigation. Togenerate facets automatically is the key to efficient faceted navigation. In Web navigationapplications, to extract the appropriate words that indicate classifications is the key togenerating facets for automatically faceted Web navigation.
