• Title: To remove or not remove Mobile Apps? A data-driven predictive model approach
• Authors: Fadi Mohsen, Dimka Karastoyanova, and George Azzopardi
• Abstract summary: We propose a data-driven predictive approach that determines whether the respective app will be removed or accepted. Our approach can support developers in improving their apps and users in downloading the ones that are less likely to be removed.

• Abstract: Mobile app stores are the key distributors of mobile applications. They regularly apply vetting processes to the deployed apps. Yet, some of these vetting processes might be inadequate or applied late. The late removal of applications might have unpleasant consequences for developers and users alike. Thus, in this work we propose a data-driven predictive approach that determines whether the respective app will be removed or accepted. It also indicates the features' relevance that help the stakeholders in the interpretation. In turn, our approach can support developers in improving their apps and users in downloading the ones that are less likely to be removed. We focus on the Google App store and we compile a new data set of 870,515 applications, 56% of which have actually been removed from the market. Our proposed approach is a bootstrap aggregating of multiple XGBoost machine learning classifiers. We propose two models: user-centered using 47 features, and developer-centered using 37 features, the ones only available before deployment. We achieve the following Areas Under the ROC Curves (AUCs) on the test set: user-centered = 0.792, developer-centered = 0.762.

  Evolving software with an increasing number of features poses challenges in terms of comprehensibility and usability. Previous work showed that the deletion of functionality is common and sometimes driven by user reviews. For most users, the removal of features is associated with negative sentiments, prompts changes in usage patterns, and may even result in user churn.

  This paper addresses the "what-if" problem of estimating the values of key performance indicators (KPIs) that would have been obtained if a different app had been implemented by the radio access network (RAN) We propose a conformal-prediction-based counterfactual analysis method for wireless systems that provides reliable "error bars" for the estimated, containing the true with a user-defined probability.

  Existing crawlers rely on app-specific, threshold-based, algorithms to assess state equivalence. We propose WEBEMBED, a novel abstraction function based on neural network embeddings and threshold-free classifiers. Our evaluation on nine web apps shows that WEBEMBED outperforms state-of-the-art techniques by detecting near-duplicates more accurately.

  Evolving software with an increasing number of features is harder to understand and thus harder to use. Too much functionality can easily impact usability, maintainability, and resource consumption. Previous work showed that the deletion of functionality is common and sometimes driven by user reviews.

Traditionally, user modeling from mobile app usage heavily relies on handcrafted feature engineering. We present a tailored AutoEncoder-coupled Transformer Network (AETN), by which we overcome these challenges and achieve the goals of reducing manual efforts and boosting performance.
