analysis of implicit interest indicators for spatial data
Information overload is a pervasive problem in many application domains. One way of addressing this problem is to create user profiles that filter out irrelevant information while presenting the users with information matching their interests. This approach has not been widely exploited in GIS. In our spatial application, we log user interactions, and implicitly infer their interests from this information to generate a user interest model. In particular, mouse movements and map browsing behaviour are analysed. Experiments presented in this paper examine the accuracy of implicitly determined spatial interests. Personalisation techniques can subsequently be applied to provide users with the most relevant information with regard to their interests.
