3rd International Workshop on App Market Analytics, WAMA 2019

Co-located with ESEC/FSE 2019, Tallin, Estonia

Software applications (or apps) are distributed very differently these days than how they were once distributed - through centralized market places (which has changed the way developers interact with users, the way software is released, and consumed). These app markets, which are now standard for mobile apps, are getting popular now for desktop apps, games, and even open source apps. Such markets make it easier for app developers to release their new apps and update their existing apps. It also makes it easier for users to search, compare and download new apps and keep their existing apps up to date. Additionally, the app markets provide useful guidance to developers so that end users have the best quality apps. Finally, the market is public facing and has unique data like user comments, release notes, app popularity, besides just the app itself. Hence, app markets can be mined and the resulting data analyzed by researchers and analytics companies. Therefore, in this workshop (happening in conjunction with ESEC/FSE 2019), we seek to bring together researchers and practitioners to discuss research challenges, ideas, initiatives and results that leverages such app market data to answer pertinent software engineering questions using analytical and empirical approaches. Furthermore, we want to incorporate interdisciplinary collaborations regarding economic aspects.

News: We are delighted to announce that Prof. Guenther Ruhe will give a keynote at WAMA 2019 on "How Much (App Market) Analytics is Enough?"

Call for Papers

We will seek original articles on studies that are related to app markets, with the end goal of making concrete recommendations to the app developers, app market developers, or other developers who provide libraries and frameworks for building apps, and end users. We especially encourage articles on:

  • Requirements in app markets (e.g., elicitation from descriptions and user reviews)
  • Feedback & reputation in app markets
    • Mining and classifying app reviews
    • Impact of app reviews
    • Interactions of reviews and pricing
  • App market design
    • App store policy compliance
    • Market mechanisms in app stores
  • App Development
    • Cross platform app development
    • App evolution and maintenance
    • Best practices
  • App project management
    • App deployment and release management
    • Challenges faced by small teams
    • Monetizing apps (e.g., optimal pricing, assessment of costs)
  • Quality of apps
    • User experience
    • Consumer perception
    • Legal and privacy issues
    • Resource utilization & power management
    • App recommendation
  • General software markets
    • Applicability of app market concepts to general software markets


We invite authors to submit any of the following kinds of workshop papers:

  • Full papers with 7 pages maximum
  • Data/Tool/Position papers with 4 pages maximum
  • Practitioner talk abstracts (500 words) are only open to practitioners and should describe in 500 words or less, a talk on a key aspect or challenge of app market analytics (primarily experience-based)
  • Posters along with a 2 page paper

Workshop papers must follow the ESEC/FSE 2019 Format and Submission Guidelines (but they do not have to be "double blind").

Please submit your papers here here.

All accepted contributions will be published in the conference electronic proceedings and in the ACM Digital Library.

At least one author of each accepted paper must register and present the paper at the workshop in order for the paper to be published in the proceedings (note that student registrations do NOT satisfy the registration requirement). See registration info here.


  • Submission Deadline: June 10, 2019 (extended)
  • Notifications: June 26, 2019
  • Camera Ready Deadline: July 1, 2019 (strict)
  • Workshop: Tuesday, August, 27 2019

"How Much (App Market) Analytics is Enough?" by Prof. Guenther Ruhe

Abstract: Given the unprecedented access to data, there is the opportunity to analyze, understand, and optimize the mechanism of the emerging app market. Needs elicitation from analyzing app reviews and social media, providing recommendations to developers, developing strategies for app deployments and release management are just a few examples of the new insights possible. But how much analytics is enough. Is “the more, the better”? The famous Aristotle (384 to 322 BC) is widely attributed with saying “It is the mark of an educated mind to rest satisfied with the degree of precision which the nature of the subject admits and not to seek exactness where only an approximation is possible.” This talk intends to discuss the question of “Return on investment” in the context of (App Market) analytics.

About the speaker: Prof. Guenther Ruhe holds an Industrial Research Chair in Software Engineering at The University of Calgary. This is a joint position between department of Computer Science and department of Electrical and Computer Engineering. Dr. Ruhe is proud to lead a research team whose primary aim is to establish and demonstrate scientific excellence in the area of Software Engineering Decision Support (SEDS) and to collaborate with industry. Ruhe owns the US patent 8,006,222 on software release planning. He won various awards such as the Alberta iCORE (Informatics Center of Research Excellence) award, an IBM research award, a Mobility Award for foreign researchers at University of Bolzano, and a Microsoft Research Software Engineering Innovation award in 2012. Ruhe was in chairing positions for various conferences such as ESEM, RE, SEKE, and SSBSE. He was a Visiting Professor at the Chinese Academy of Sciences, Institute for Software, Beijing. Since 2016, he serves as the Editor in Chief of the journal of Information and Software Technology, published by Elsevier. His main research interests are in the areas of Product Release Planning, Software Project Management, Decision Support, Open Innovation, Data Analytics, Empirical Software Engineering as well as Search-based Software Engineering. He is a Senior member of IEEE and a member of the ACM. Dr. Ruhe is the Founder and CEO of Expert Decisions Inc., a University of Calgary spin-off company created in 2003.
