MatchBase: User-Driven Context Acquisition for Increased Efficiency of Computer-Mediated Communication


The aim of this thesis is to develop a system that supports the effectiveness communication of remote users by means of a user-driven approach for acquiring the contacter's preferences.

An interruption situation consists of two participants, a contactee (recipient) and a contacter (sender). The contacter wants to request or deliver information and the contactee receives the messages from the contacter. Prior work on analysing and improving the interruption problem, examine the aspect of avoiding interruptions being disruptive, but interruptions also can be advantageous for contacter as well as for contactee. We include both communication partners to improve effectiveness of interruption. Our approach gains context information of the contacter and the contactee, for matching their preferences. The contacter manually provides the system with his preferences and thus directly sets the parameters' values for the further matching calculation. A user-query enquires the user about specific attributes of the contacting situation. These attributes are for instance the importance and urgency of the message, its subject and additionally the relationship of the participants. The gathered preferences of the participants will be used to estimate how effective an interruption will be. To calculate this degree of effectiveness, which determines the further system behaviour, a Bayesian Network will be modelled and implemented. The suitability of this approach and the implemented system respectively will be tested and validated.
