    A Journey to comprehensible User Behavior Models
    (Softwaretechnik-Trends Band 40, Heft 3, 2020) Jung, Reiner; Jürgensen, Lars
    Engineers use workload models to estimate the future utilization of services, understand usage profiles of services, and drive plans to evolve software systems. We usually separate workloads in intensities and user behavior models in context of performance evaluations and forecasting. Outside of software engineering user behaviors are often collected in clickstreams. They may represent the complete history of a user at one site. Ideally, a number of clickstreams can be transformed into a user behavior model containing multiple typical behavior pattern usable for a workload model. While the collection of user behaviors is fairly simple, the extraction of behavioral patterns is complicated. Current approaches are tailored for specific domains, are only applicable for one purpose, and refuse to be understood and analyzed in a meaningful way. In this paper, we introduce our latest advances to identify a suitable identification approach and layout further obstacles which must overcome to have comprehensible user behavior models.

    Reflecting on Social Media Behavior by Structuring and Exploring Posts and Comments
    (i-com: Vol. 19, No. 3, 2021) Herder, Eelco; Roßner, Daniel; Atzenbeck, Claus
    Social networks use several user interaction techniques for enabling and soliciting user responses, such as posts, likes and comments. Some of these triggers may lead to posts or comments that a user may regret at a later stage. In this article, we investigate how users may be supported in reflecting upon their past activities, making use of an exploratory spatial hypertext tool. We discuss how we transform raw Facebook data dumps into a graph-based structure and reflect upon design decisions. First results provide insights in users motivations for using such a tool and confirm that the approach helps them in discovering past activities that they perceive as outdated or even embarrassing.

    A Technical Framework for Investigating the Impact of Design Elements in the Wild: Using Instagram as an Example
    (Mensch und Computer 2021 - Tagungsband, 2021) Helfenstein, Mischa; Zweig, Katharina Anna; Herrlich, Marc
    It is important to investigate effects of different interface designs not only for small sample systems but also for large real-world applications. However, it is not always possible for researchers to get direct access to these applications or relevant user data. Studies investigating possible negative effects such as keeping users occupied longer or making them spent more money might not get the consent of the application’s creator. We present a technical architecture and an open source implementation to conduct comparative studies on external apps by enabling researchers to turn specific interface elements on and off. The current implementation requires that the target app is available as a web app and that the study participants access it through a custom Android app. While the framework is not limited to a certain app, we use Instagram as an example and present results from a proof-of-concept study showcasing the framework.
