Existing information retrieval-based change impact analysis methods select a single method to transform the source code corpus into vectors in a process known as indexing. The single method is chosen from two primary methods, known as the bag-of-words and word embedding models, each having their specific advantages and disadvantages. The bag-of-words model records every word in the source code but ignores contextual information in the corpus. The word embedding model records the contextual information but loses detail for individual words. To address this problem, we propose a structure-driven method for information retrieval-based change impact analysis (named SDM-CIA). SDM-CIA integrates the bag-of-words and word embedding models based on the software\u2019s structure. Our experiments using a standard benchmark shows that when compared with the existing methods, SDM-CIA improves on precision performance, recall performance, F-score performance, and MRR performance by an average of 3.65%, 3.82%, 3.6%, and 10.28%, respectively. Our experiments confirm the effectiveness of SDM-CIA.<\/jats:p>","DOI":"10.1155\/2018\/5494209","type":"journal-article","created":{"date-parts":[[2018,10,4]],"date-time":"2018-10-04T19:42:24Z","timestamp":1538682144000},"page":"1-16","source":"Crossref","is-referenced-by-count":2,"title":["A Structure-Driven Method for Information Retrieval-Based Software Change Impact Analysis"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9573-7678","authenticated-orcid":true,"given":"Yun","family":"He","sequence":"first","affiliation":[{"name":"Software School, Yunnan University, Kunming, Yunnan, China"},{"name":"Key Laboratory for Software Engineering of Yunnan Province, Kunming, Yunnan, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3257-213X","authenticated-orcid":true,"given":"Tong","family":"Li","sequence":"additional","affiliation":[{"name":"Software School, Yunnan University, Kunming, Yunnan, China"},{"name":"Key Laboratory for Software Engineering of Yunnan Province, Kunming, Yunnan, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2026-5378","authenticated-orcid":true,"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Software School, Yunnan University, Kunming, Yunnan, China"},{"name":"Key Laboratory for Software Engineering of Yunnan Province, Kunming, Yunnan, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4788-5593","authenticated-orcid":true,"given":"Wei","family":"Lan","sequence":"additional","affiliation":[{"name":"Software School, Yunnan University, Kunming, Yunnan, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8852-5685","authenticated-orcid":true,"given":"Xiang","family":"Li","sequence":"additional","affiliation":[{"name":"Software School, Yunnan University, Kunming, Yunnan, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1007\/s10664-016-9441-9"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1002\/smr.567"},{"issue":"1","key":"4","first-page":"17","volume":"33","year":"2017","journal-title":"Journal of Information Science and Engineering"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/s10664-012-9224-x"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1007\/s13042-010-0001-0"},{"key":"12","first-page":"3111","volume":"26","year":"2013","journal-title":"Advances in Neural Information Processing Systems"},{"year":"2015","key":"15"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1145\/3089649.3089657"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/tse.2016.2620458"},{"issue":"3","key":"21","first-page":"503","volume":"53","year":"2016","journal-title":"Journal of Computer Research and Development"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1145\/13487689.13487691"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1007\/s10664-011-9194-4"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.1002\/(sici)1097-4571(199009)41:6<391::aid-asi1>3.0.co;2-9"},{"key":"29","first-page":"993","volume":"3","year":"2003","journal-title":"Journal of Machine Learning Research"},{"key":"30","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2008.04.030"},{"issue":"6","key":"31","first-page":"843","volume":"10","year":"2015","journal-title":"CAAI Transactions on Intelligent Systems"},{"key":"32","doi-asserted-by":"publisher","DOI":"10.3724\/sp.j.1016.2012.01655"},{"key":"33","doi-asserted-by":"publisher","DOI":"10.1016\/j.infsof.2017.04.003"},{"key":"34","doi-asserted-by":"publisher","DOI":"10.1109\/tse.2007.1016"},{"issue":"2","key":"35","first-page":"139","volume":"1","year":"2012","journal-title":"Journal of Frontiers of Computer Science and Technology"}],"container-title":["Scientific Programming"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2018\/5494209.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2018\/5494209.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2018\/5494209.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,10,4]],"date-time":"2018-10-04T19:42:33Z","timestamp":1538682153000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/sp\/2018\/5494209\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,10,4]]},"references-count":20,"alternative-id":["5494209","5494209"],"URL":"https:\/\/doi.org\/10.1155\/2018\/5494209","relation":{},"ISSN":["1058-9244","1875-919X"],"issn-type":[{"type":"print","value":"1058-9244"},{"type":"electronic","value":"1875-919X"}],"subject":[],"published":{"date-parts":[[2018,10,4]]}}}
