RepliComment: Identifying clones in code comments

Code comments are the primary means to document implementation and facilitate program comprehension. Thus, their quality should be a concern improve maintenance. While much effort has been dedicated detecting bad smells, such as clones in code, little work focused on comments. In this paper we present our solution detect that developers fix. RepliComment can automatically analyze Java projects report instances of copy-and-paste errors comments, point which fixed. Moreover, it when signs poorly written Developers fix these too order code documentation. Our evaluation 10 well-known open source identified over 11K comment clones, 1,300 them potentially critical. We own previous Blasi Gorla (2018), could only find 36 issues same dataset. manual inspection 412 reported by reveals achieves precision 79% reporting critical clones. The 200 additional filters out being legitimate, not evince any false negative.
