User models are the set of beliefs a (software) system holds about a user. User-adapted applications, and increasingly, web sites, use a user model to help the interaction with a user. As these models start to contain more personal and sensitive information, and affect the experience of the software user, it becomes important for the user to be able to inspect and control that data. This thesis presents work that aims to help users see an overview of the data and beliefs contained in their user model. While there has been work on scrutable user models that support exploration and user control Kay99, ZRNG99, they have been focused on the inspection of individual model components. This thesis helps users quickly search for interesting features in models of several hundreds of components. This thesis presents the design and implementation of three iterations of the tool, and user tests of each design. The final implementation is evaluated in trial with more than 50 users. Much recent work on user-adapted systems has involved adaptive hypertext and services on the World Wide Web. An important feature of this work is its ability to work as a natural part of a web site. Furthermore, the user model format presented here leverages an Internet standard for complex metadata, allowing for inter-operation with a broad range of web services.
