Our results, based on an analysis of 11,537 apps from the Samsung Android and BlackBerry World app stores, indicate that the rating of 89% of these apps can be predicted with 100% accuracy. Our prediction model is built by using feature and rating information from the existing apps offered in the App Store and it yields highly accurate rating predictions, using only a few (11-12) existing apps for case-based prediction. These findings may have important implications for require- ments engineering in app stores: They indicate that app devel- opers may be able to obtain (very accurate) assessments of the customer reaction to their proposed feature sets (requirements), thereby providing new opportunities to support the requirements elicitation process for app developers. date: 2018-10-15 date_type: published publisher: IEEE official_url: https://doi.org/10.1109/RE.2018.00018 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1589680 doi: 10.1109/RE.2018.00018 isbn_13: 978-1-5386-7418-5 lyricists_name: Harman, Mark lyricists_name: Jia, Yue lyricists_name: Sarro, Federica lyricists_id: MHARM36 lyricists_id: YJIAX90 lyricists_id: FSSAR72 actors_name: Sarro, Federica actors_id: FSSAR72 actors_role: owner full_text_status: public place_of_pub: Banff, Alberta, Canada pagerange: 76-87 event_title: IEEE 26th International Requirements Engineering Conference, Banff, Alberta, Canada event_location: Banff, Canada event_dates: 20 August 2018 - 24 August 2018 institution: IEEE 26th International Requirements Engineering Conference (RE) issn: 2332-6441 book_title: Proceedings of the IEEE 26th International Requirements Engineering Conference :RE 18 citation: Sarro, F; Harman, M; Jia, Y; Zhang, Y; (2018) Customer Rating Reactions Can Be Predicted Purely Using App Features.
