    Abstract

    The usage of computer applications in the construction industry is increasing, as is the complexity of software applications and this makes it difficult for project personnel to maintain familiarity. Furthermore, the causes of practical problems, such as project delays and cost over-runs, are often not derivable from the output of most software. A question answering system provides a means for directly extracting knowledge from this output. This paper begins with an examination of issues involved in building such a system. An emerging industry standard, ifcXML, is adopted as the knowledge representation format, thereby reducing the effort that is necessary to build a knowledge base. We then explore the mechanisms that use information in the knowledge base for question understanding. A prototype system has been built and tested to illustrate usefulness for project management applications.
