Existing application software perhaps has no requirements document or requirements document does not represent the application. The situation creates a problem in application software maintenance or reengineering. Thus, requirements document should be reconstructed from the existing application software. Effort on reconstructing a requirements document from the existing application software is similar to requirements document construction for new application software, needs requirements elicitation. Requirements elicitation can be done using an ontology model that captures end-to-end interaction between users and system.
