Knowledge Representation of Software Faults Based on Open Bug Repository

摘要

Bug repository of open source software contains a mass of historical data about behaviors of software failure and life-cycle of bug process. By surveying and analyzing three kinds of open source software as Apache, Eclipse, and Firefox, a practical knowledge representation of software faults is properly depicted in this paper. An algorithm is further given to transfer a software bug report to a software fault case, greatly reducing cost and time for constructing case base of software fault from scratch. All of these results have significant advantages for developing an intelligent fault diagnosis system based on case-reasoning.
