  • SIGIR - User Interaction in Mobile Web Search
    Proceedings of the 39th International ACM SIGIR conference on Research and Development in Information Retrieval, 2016
    Co-Authors: Jaewon Kim
    Abstract:

    From previous studies, we believe that search behaviour on touch-enabled mobile devices is different from the behaviour with desktop screens. In the proposed research, we intend to explore User Interaction while searching with the aim of improving search experience on mobile devices.

  • UMAP - Improving Mobile Recommendations through Context-Aware User Interaction
    User Modeling Adaptation and Personalization, 2014
    Co-Authors: Béatrice Lamche
    Abstract:

    Mobile recommender systems provide personalized recommendations to help deal with today’s information overload. However, due to spatial limitations in mobile interfaces and uncertainty of the User’s preferences in the beginning, the improvement of the User experience remains one of the main challenges when designing these systems and has not been investigated thoroughly. This paper describes the aim and progress of the author’s PhD studies on the User Interaction, usability and accuracy of mobile recommender systems. The approach aims to combine different User Interaction methods with context-awareness to allow User-friendly personalized mobile recommendations.

  • Decisions@RecSys - Selecting Gestural User Interaction Patterns for Recommender Applications on Smartphones
    2013
    Co-Authors: Wolfgang Wörndl, Jan Weicker, Béatrice Lamche
    Abstract:

    Modern smartphones allow for gestural touchscreen and free-form User Interaction such as swiping across the touchscreen or shaking the device. However, User acceptance of motion gestures in recommender systems have not been studied much. In this work, we investigated the usage of gestural Interaction patterns for mobile recommender systems. We designed a prototype that implemented at least two input methods for each available function: standard on-screen buttons or menu options, and also a gestural Interaction pattern. In a User study, we then compared what input method Users would choose for a given function. Results showed that gesture usage depended on the specific task. In general, Users preferred simpler gestures and rarely switched their input method for a function during the test.

  • SIGIR - User Interaction Sequences for Search Satisfaction Prediction
    Proceedings of the 40th International ACM SIGIR Conference on Research and Development in Information Retrieval, 2017
    Co-Authors: Rishabh Mehrotra, Imed Zitouni, Ahmed Hassan Awadallah, Ahmed El Kholy, Madian Khabsa
    Abstract:

    Detecting and understanding implicit measures of User satisfaction are essential for meaningful experimentation aimed at enhancing web search quality. While most existing studies on satisfaction prediction rely on Users' click activity and query reformulation behavior, often such signals are not available for all search sessions and as a result, not useful in predicting satisfaction. On the other hand, User Interaction data (such as mouse cursor movement) is far richer than just click data and can provide useful signals for predicting User satisfaction. In this work, we focus on considering holistic view of User Interaction with the search engine result page (SERP) and construct detailed universal Interaction sequences of their activity. We propose novel ways of leveraging the universal Interaction sequences to automatically extract informative, interpretable subsequences. In addition to extracting frequent, discriminatory and interleaved subsequences, we propose a Hawkes process model to incorporate temporal aspects of User Interaction. Through extensive experimentation we show that encoding the extracted subsequences as features enables us to achieve significant improvements in predicting User satisfaction. We additionally present an analysis of the correlation between various subsequences and User satisfaction. Finally, we demonstrate the usefulness of the proposed approach in covering abandonment cases. Our findings provide a valuable tool for fine-grained analysis of User Interaction behavior for metric development.
