Query: User Modeling Combining Access Logs, Page Content and Semantics   The paper proposes an approach to modeling users of large Web sites based on
combining different data sources: access logs and content of the accessed pages
are combined with semantic information about the Web pages, the users and the
accesses of the users to the Web site. The assumption is that we are dealing
with a large Web site providing content to a large number of users accessing
the site. The proposed approach represents each user by a set of features
derived from the different data sources, where some feature values may be
missing for some users. It further enables user modeling based on the provided
characteristics of the targeted user subset. The approach is evaluated on
real-world data where we compare performance of the automatic assignment of a
user to a predefined user segment when different data sources are used to
represent the users.
