Towards Leveraging Fine-Grained Dependencies to Check Requirements Traceability Correctness

Efficient software maintenance and evolution rely heavily on effective software traceability, which is crucial for understanding the relationships between code elements and their corresponding requirements. However, ensuring the accuracy of trace links, whether manually or automatically, is a significant challenge due to the labor-intensive and error-prone nature of traceability tasks. The granularity issue in traceability compounds this challenge, as most existing research focuses on class-level traceability, while fine-grained dependencies (e.g., method-level traces) are more pertinent in daily development practices. Our primary aim is to facilitate the checking of requirement-to-method traces. To this end, we investigate an approach that utilizes the method's calling information and textual embeddings of requirement-to-method traces to identify inaccuracies in trace links. Our preliminary results are promising. By leveraging a Ran-dom Forest (RF) classifier, we have achieved notable improvements in both precision
$(\approx 10\%)$
and recall
$(\approx 30\%)$
compared to existing methods. This advancement highlights the potential of our method in enhancing the accuracy and efficiency of traceability processes in software development.
