Requirements traceability provides critical support throughout all phases of a software development project. However practice has repeatedly shown the difficulties involved in long-term maintenance of traditional traceability matrices. Dynamic retrieval methods minimize the need for creating and maintaining explicit links and can significantly reduce the(More)
This paper describes a technique for automating the detection and classification of non-functional requirements related to properties such as security, performance , and usability. Early detection of non-functional requirements enables them to be incorporated into the initial architectural design instead of being refactored in at a later date. The approach(More)
This paper introduces an information retrieval based approach for automating the detection and classification of non-functional requirements (NFRs). Early detection of NFRs is useful because it enables system level constraints to be considered and incorporated into early architectural designs as opposed to being refactored in at a later time. Candidate NFRs(More)
Dynamic trace retrieval provides an alternate option to traditional traceability methods such as matrices, hyperlinks, and manual link construction. Instead of relying upon manually constructed and maintained traces, links are generated dynamically on an 'as-needed' basis using information retrieval techniques. Prior work in this area has indicated that in(More)
Requirements traceability provides critical support in helping manage the evolution of software systems. Establishing and maintaining trace links is an arduous problem requiring intensive human effort when traces need to be established manually. Automatic retrieval tools can help maintain traceability links by dynamically identifying traces between(More)
Novelty detection system is used to extract documents with new or novel information from list of documents. Without looking for lot of redundant information, we can get useful information in a limited time. Cosine similarity and Language modeling are the two emerging techniques of information retrieval in today's scenario. The current study performs the(More)
