ABSTRACT
Information discovery and analysis can be enabled by a wide-range
of technologies. Typically analysts have to perform data searches against
very large heterogeneous repositories, extract information from result
sets, summarize and interpret the results, and form conclusions based
on the results. In intelligent information access, tools can facilitate
these activities for the analyst throughout the process, decreasing
task time and increasing comprehensiveness and accuracy of search if
tools are appropriately chosen and applied. The purpose of this paper
is to provide an overview of five intelligent information access technologies:
information retrieval, summarization, information extraction, text
clustering, and question answering. We aim to provide a brief characterization
of state of the art in each area, point to some example tools, and indicate
the potential benefit of each of these areas to end users.
