Interactive retrieval of complex documents

摘要

Documents such as reports, articles, memos, and forms have complex structure and layout, as well as multimedia content. Information systems that represent these aspects of documents must be able to handle queries more complex than in typical database or text retrieval systems. In this paper, we describe an interface that allows the specification of uncertain queries and combines evidence about the relevance of documents to produce an overall ranking. We also report the results of an experiment that addresses some of the cognitive aspects of such an interface.
