Abstract

The term traceability is an important concept regarding software development. It enables software engineers to trace requirements from their origin to fulfillment. Maintaining traceability manually is a time consuming and expensive job. Information retrieval methods provide a mean of automation for requirement traceability. A visible number of IR based traceability techniques have been proposed in the literature, but the adoption of these techniques in the industry is limited. In this paper, we examine the information retrieval-based traceability recovery approaches through systematic literature review. We presented a synthesis of these techniques. We also identified challenges that are potentially limiting the adoption of IR based traceability recovery approaches. We conclude that term mismatch is a major barrier faced by IR based approaches. We also did classify the approaches that are attempting to solve the term mismatch problem.
