User Review-Based Change File Localization for Mobile Applications

In the current mobile app development, novel and emerging DevOps practices (e.g., Continuous Delivery, Integration, and user feedback analysis) and tools are becoming more widespread. For instance, the integration of user feedback (provided in the form of user reviews) in the software release cycle represents a valuable asset for the maintenance and evolution of mobile apps. To fully make use of these assets, it is highly desirable for developers to establish semantic links between the user reviews and the software artefacts to be changed (e.g., source code and documentation), and thus to localize the potential files to change for addressing the user feedback. In this paper, we propose RISING (Review Integration via claSsification, clusterIng, and linkiNG), an automated approach to support the continuous integration of user feedback via classification, clustering, and linking of user reviews. RISING leverages domain-specific constraint information and semi-supervised learning to group user reviews into multiple fine-grained clusters concerning similar users' requests. Then, by combining the textual information from both commit messages and source code, it automatically localizes potential change files to accommodate the users' requests. Our empirical studies demonstrate that the proposed approach outperforms the state-of-the-art baseline work in terms of clustering and localization accuracy, and thus produces more reliable results.Comment: 15 pages, 3 figures, 8 table

The Role of User Reviews in App Updates:A Preliminary Investigation on App Release Notes*

Release planning for mobile apps has recently become an area of active research. Prior research in this area concentrated on the analysis of release notes and on tracking user reviews to support app evolution with issue trackers. However, little is known about the impact of user reviews on the evolution of mobile apps. Our work explores the role of user reviews in app updates based on release notes. For this purpose, we collected user reviews and release notes of Spotify, the number one' app in the 'Music' category in Apple App Store, as the research data. Then, we manually removed non-informative parts of each release note, and manually determined the relevance of the app reviews with respect to the release notes. We did this by using Word2Vec calculation techniques based on the top 80 app release notes with the highest similarities. Our empirical results show that more than 60 % of the matched reviews are actually irrelevant to the corresponding release notes. When zooming in at these relevant user reviews, we found that around half of them were posted before the new release and referred to requests, suggestions, and complaints. Whereas, the other half of the relevant user reviews were posted after updating the apps and concentrated more on bug reports and praise.</p

The digitization of music and the accessibility of the artist

©Journal of Professional Communication, ISSN: 1920-685. All rights reservedThis article uses case studies to explore two ways in which technology can impact on artist production. First, technological innovations could facilitate many things that are not new by rather making existing processes better or cheaper in ways that might alter the situation meaningfully. Second, technology can change art through the more profound revision of the role of artist and art-perceiver (Fineberg, 2006). This article examines several examples of how the music industry has been impacted by new technology: Radiohead Rainbows, slicethepie.com, Ditto Music, Music Rainbow, YouTube Orchestra, micro-chunking and LiveFi. The article examines the impact of new technologies on classical music.Peer reviewe

The Influence of User Feedback on Complementary Innovation in Platform Ecosystems: NLP Evidence on the Value of Multihoming

We study how user feedback affects innovation of multihomed applications within and across platform ecosystems. Therefore, we conduct a quantitative NLP based case study. Our sample consists of 10 multihomed applications with more than 325,000 user reviews on Apple’s iOS and Google’s Android platform between January and March 2021. We analyze how user reviews translate into functional feature releases of the selected applications within and across platforms. We report three findings. First, we find that about 61% of the functional feature improvements on both platforms were previously demanded by users in the form of user feedback. Second, we show that user feedback of iOS users is more likely to be incorporated compared to Android users’ feedback. Finally, we observe that about 10% of feature releases are inspired by cross-platform feedback, providing initial evidence that user feedback from multihoming applications might stimulate cross-platform innovation and enhance the applications’ quality and innovativeness

RoseMatcher: Identifying the Impact of User Reviews on App Updates

Release planning for mobile apps has recently become an area of active research. Prior research concentrated on app analysis based on app release notes in App Store, or tracking user reviews to support app evolution with issue trackers. However, as a platform for development teams to communicate with users, Apple Store has not been studied for detecting the relevance between release notes and user reviews. In this paper, we introduce RoseMatcher, an automatic approach to match relevant user reviews with app release notes, and identify matched pairs with high confidence. We collected 944 release notes and 1,046,862 user reviews from 5 mobile apps in the Apple App Store as research data, and evaluated the effectiveness and accuracy of RoseMatcher. Our evaluation shows that RoseMatcher can reach a hit ratio of 0.718 for identifying relevant matched pairs. We further conducted manual labelling and content analysis on 984 relevant matched pairs, and defined 8 roles user reviews play in app update according to the relationship between release notes and user reviews in the relevant matched pairs. The study results show that release notes tend to respond and solve feature requests, bug reports, and complaints raised in user reviews, while user reviews also tend to give positive, negative, and constructive feedback on app updates. Additionally, in the time dimension, the relevant reviews of release notes tend to be posed in a small period of time before and after the release of release notes. In the matched pairs, the time interval between the post time of release notes and user reviews reaches a maximum of three years and an average of one year. These findings indicate that the development teams do adopt user reviews when updating apps, and users show their interest in app release notes.Comment: 18 pages, 7 figure

Culture and disaster risk management - synthesis of citizens’ reactions and opinions during 6 Citizen Summits : Romania, Malta, Italy, Germany, Portugal and the Netherlands

The analyses and results in this document are based on the data collected during six Citizen Summits held in A) Romania (Bucharest) on July 9th, 2016 B) Malta on July 16th, 2016 C) Italy (Rome) on June 17th, 2017 D) Germany (Frankfurt) on June 24th, 2017 E) Portugal (Lisbon) April 14th, 2018 F) The Netherlands (Utrecht)on May 12th, 2018. All Citizen Summits were designed as one-day events combining public information with feedback gathering through different methods of data collection, as laid out in Deliverable D5.1 (Structural design & methodology for Citizen Summits). A total of 619 citizens participated in the six events. In the morning session, the Citizen Summits started with a presentation of the CARISMAND project and its main goals and concepts. Then, several sets of questions with pre-defined answer options were posed to the audience and responses collected via an audience response system. All questions in this part of the event aimed to explore citizens’ attitudes, perceptions, and intended behaviours related to disasters and disaster risks. Between these sets of questions, additional presentations were held that informed the audience about state-of-the-art disaster preparedness and response topics (e.g., large-scale disaster scenario exercises, use of social media and mobile phone apps), as well as CARISMAND research findings. Furthermore, the last round of Citizen Summits (CS5 in Lisbon and CS6 in Utrecht) were organised and designed to additionally discuss and collect feedback on recommendations for citizens, which have all been formulated on the basis of Work Packages 2-10 results and in coordination with the Work Package 11 brief. These Toolkit recommendations will form one of the core elements of the Work Package 9 CARISMAND Toolkit. In the afternoon session of each event, small moderated group discussions (with 8-12 participants each) of approximately 2 hours’ duration were held, which aimed to gather citizens’ direct feedback on the topics presented in the morning sessions, following a detailed discussion guideline. For a detailed overview of all questions asked and topics discussed, please see Appendices A-1 to A-3. The rest of this report is structured in six main sections: After the executive summary and this introduction, the third section will present an overview of the different methods applied. The fourth section will provide a synthesis of quantitative and qualitative data collected during all Citizen Summits. The fifth section will present the evaluation of CARISMAND Toolkit recommendations for citizens, followed by a final concluding chapter.The project was co-funded by the European Commission within the Horizon2020 Programme (2014-2020).peer-reviewe

Using technology in service delivery to families, children and young people

This paper provides an overview of how the innovative use of technology can add value to service delivery in organisations working with families, children and young people.Key messages:Most Australians have access to the Internet and use mobile devices to connect from anywhere, at any time. Research suggests that even isolated and marginalised groups are using technology in their everyday lives.For some groups (e.g., young people), technology may be their preferred method of communication.There appears to be a difference between how people are using the Internet (regularly, from anywhere, connecting with social networks, investigating services) and how some organisations are engaging with it (infrequently, in one direction).Technology works best when used to augment or improve existing services for clients, or to offer innovative approaches to existing services.Technology can be used in diverse ways for organisational improvement (e.g., remote access, staff training, professional development) or client services (e.g., online counselling, SMS appointment reminders, access to resources).Using technology does not necessarily involve large monetary investments or reinventing the wheel in terms of policy and procedures. Often it is a matter of adapting and refining existing services and policies to better suit the online world.Incorporating technology into services takes time, and will need continued assessment and refinement to be successful
