Traceability links can assist in software maintenance tasks. There are some automatic traceability recovery methods. Most of them are similarity-based methods recovering links by comparing representation similarity between requirements and code. They cannot work well if there are some links indepen-dent of the representation similarity. Herein to cover weakness of them and im-prove the accuracy of recovery, we propose a method that extends the similari-ty-based method using two elemental techniques: a log-based traceability re-covery method using the configuration management log and a link recommen-dation from user feedback. These techniques are independent of the representa-tion similarity between requirements and code. As a result of applying our me-thod to a large enterprise system, we successfully improved both recall and pre-cision by more than a 20 percent point in comparison with singly applying the similarity-based method (recall: 60.2% to 80.4%, precision: 41.1% to 64.8%).
