READFAST: Browsing large documents through unified famous objects (UFO)

While the problem to find needed information on the Web is being solved by the major search engines, access to the information in large text documents (e-books, conference proceedings, product manuals, etc) is still very rudimentary. Thus, keyword-search is often the only way to find the needle in the haystack. There is abundance of relevant research results in the Semantic Web research community that offers more robust access interfaces compared to keyword-search. Here we describe a new hybrid document browser that offers advanced user experience combining keyword-search with navigation over an automatically inferred hierarchical document index. The internal representation of the browsing index as a collection of UFOs yields more relevant search results and improves user experience.
