Natural language access to information systems. An evaluation study of its acceptance by end users

摘要

The question is asked whether it is feasible to use subsets of natural languages as query languages for data bases in actual applications using the question answering system “USER SPECIALTY LANGUAGES” (USL). Methods of evaluating a natural language based information system will be discussed. The results (error and language structure evaluation) suggest how to form the general architecture of application systems which use a subset of German as query language.
