The role of the coverage analysis during IR-based traceability recovery: A controlled experiment
Andrea De Lucia, Rocco Oliveto, Genoveffa Tortora · 2009
This paper presents a two-steps process aiming at improving the tracing performances of the software engineer when using an IR-based traceability recovery tool. In the first step the software engineer performs an incremental coarse-grained traceability recovery between a set of source artefacts and a set of target artefacts. During this step he/she traces as many links as possible keeping low the effort to discard false positives. In the second step he/she uses a coverage link analysis aiming at identifying source artefacts poorly traced and guiding focused fine-grained traceability recovery sessions to recover links missed in the first step. The results achieved in a reported controlled experiment demonstrate that the proposed approach significantly increases the amount of correct links traced by the software engineer with respect to a tradition process.
