When less is more: a traceability recovery paradox

Prof. Giuliano Antoniol | 19.04.2016 | 11:00 Uhr | I.2.35


The IEEE glossary defines traceability as “the degree to which a relationship can be established between two or more products of the development process.” Traceability underlies many important software and systems engineering activities, such as program understanding, change impact analysis, contractual agreement as well as verification and validation. Despite important research advances in the automated creation and maintenance of trace links, artifact traceability is still not completely understood.

This talk briefly introduces key traceability ideas; the basic information retrieval models and traceability recovery approaches. It briefly summarizes the state of the art in traceability recovery and recent advances. Finally it discusses an on going research effort to determine an optimal and minimal set of candidate links to build a robust traceability recovering recognizer. Surprisingly, it may happen that a system built with just a handful of carefully selected candidate links, outperforms systems built using much more information. The talk presents preliminary results on publicly available datasets and it discuss findings, implications and research directions.
