To effectively extract requirements from user comments, it is important to determine informative user comments. However, existing studies have mainly focused on NLP-based methods for analyzing user comments, rather than defining a set of user comments to be analyzed. If target user comments are not clearly determined, duplicate requirements can be discovered or new requirements cannot be discovered. To tackle this problem, we present a new method which defines a set of target corpora from user comments. Our method automatically defines a set of target corpora to be analyzed by identifying underlying temporal changes in user comments. We applied our method to real-world user comments collected from a mobile application store. We confirmed that our method successfully defined a set of corpora which aids the effective requirements elicitation, and facilitated discovering new requirements while avoiding the derivation of redundant requirements. <\/jats:p>","DOI":"10.1142\/s021819402250022x","type":"journal-article","created":{"date-parts":[[2022,4,29]],"date-time":"2022-04-29T14:24:46Z","timestamp":1651242286000},"page":"439-456","source":"Crossref","is-referenced-by-count":4,"title":["Identifying Temporal Corpus for Enhanced User Comments Analysis"],"prefix":"10.1142","volume":"32","author":[{"given":"Jongwook","family":"Jeong","sequence":"first","affiliation":[{"name":"Department of Computer Science, Korea Military Academy, 574 Hwarang-ro Gongneung 2-dong Nowon-gu, Seoul 01805, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youn Kyu","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Hongik University, 94 Wausan-ro Sangsu-dong Mapo-gu Seoul 04066, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2022,4,28]]},"reference":[{"key":"S021819402250022XBIB001","doi-asserted-by":"publisher","DOI":"10.1109\/RE.2013.6636712"},{"key":"S021819402250022XBIB002","doi-asserted-by":"publisher","DOI":"10.1145\/1935826.1935932"},{"key":"S021819402250022XBIB003","doi-asserted-by":"publisher","DOI":"10.1145\/2568225.2568263"},{"key":"S021819402250022XBIB004","doi-asserted-by":"publisher","DOI":"10.1109\/ASE.2015.57"},{"key":"S021819402250022XBIB005","doi-asserted-by":"publisher","DOI":"10.1109\/RE.2015.7320410"},{"key":"S021819402250022XBIB006","first-page":"382","volume-title":"IEEE 28th Int.
