Evaluating the Effectiveness of Various IR Models for Requirements Traceability
Manpreet Kaur, Harpreet Kaur · 2021
A frequently asked question during software development life cycle is: “Which source code document(s) implement requirement X?” Requirements traceability (RT) involves uncovering links between source code entities and requirement specification documents. Information Retrieval (IR) techniques are used to perform requirements traceability. There are not many studies that determine the effectiveness of various IR techniques in terms of precision, recall and ranking on big data. In this paper, we compare standard vector space model, probabilistic approach based Jensen-Shannon similarity model and dimensionality reduction based Latent Semantic Indexing model on 10 open source software systems in terms of precision, recall and ranking.
