Existing application software perhaps has no requirements document or unsuitable requirements document. It makes a problem in application maintenance or reengineering. As consequences, requirements document should be reconstructed from the existing application software. Creating requirements ontology of existing software is the fundamental strategy to the proposed requirements reconstruction method. This ontology is developed by capturing end-to-end interaction between users and system. Thus, without software documentation and source code, one still is able to reconstruct the requirements. The existing software should be executed and then observed its behavior in term of end-to-end interaction on each starting point in which identified on the interface.
