Enhanced Requirement Traceability Link Using Developer's Updated Activity

In the software development cycle, the requirement traceability link is one of the important factors. Information retrieval techniques typically produce links with low precision and/or recall because, due to their very nature, they depend on the textual similarity between requirements and source code. The developers may not evolve requirements in synchronization with source code. But, they frequently update other sources of information including CVS/SVN repositories, bug-tracking systems, mailing lists, forums, and blogs. These sources of information will be used to build improved requirement traceability-recovery approaches. After the source code was developed, the developer compiles the source code and commits the source code into versions. Then admin needs to compare the templates and versions based on similarity measurement. Based on textual comparison, the similarity is calculated. The admin can do the same process for the forum requirements.
