    Personalization today has wide spread use on many Web sites. Systems and applications store preferences and information about users in order to provide personalized access. However, these systems store user profiles in proprietary formats. Although some of these systems store similar information about the user., exchange or reuse of information is not possible and information is duplicated. Additionally, since user profiles tend to be deeply buried inside such systems, users have little control over them. This paper proposes the use of a common ontology-based user context model as a basis for the exchange of user profiles between multiple systems and, thus, as a foundation for cross-system personalization.

    Algorithms designed to support users in retrieving relevant information base their relevance computations on user profiles, in which representations of the users interests are maintained. This paper focuses on the use of supervised machine learning techniques to induce user profiles for Intelligent Information Access. The access must be personalized by profiles allowing users to retrieve information on the basis of conceptual content. To address this issue, we propose a method to learn sense-based user profiles based on WordNet, a lexical database.

    Personalization in digital libraries?

    Although digital libraries are tailored to the information needs of a specific community, they are large and broad enough in scope to create individual information overload. Digital library personalization reduces the gap between the content offered by the library and individual information needs. Based on an extended view on personalization in digital libraries, this paper discusses various personalization methods for digital libraries. The advantages and challenges of founding personalization on a better understanding of the library user is illustrated by three advanced personalization approaches: Personal Reference Libraries, Collaborative Content Annotation, and modeling and exploitation of Personal Web Context. Each of these approaches focuses on another individual aspect in the interaction between the library and its user. In addition, we also take a closer look at the limitations and challenges of personalization in digital library.
