The Internet is
ooded with Information and the last decade its size has
grown so many times that information search and presentation have become
tedious tasks even for experienced users. Minor changes to existing resources
can alter the situation and lead to major changes to the end user experi-
ence. In this manuscript we present the dynamic web personalization and
document grouping infrastructure for meta-portals and the evaluation of our
mechanism on a meta-portal. A meta-portal is an informational node where
articles from dierent sources are collected and presented in a categorized
and personalized manner. The web personalization mechanism is based on
dynamic creation and update of user proles according to the users prefer-
ences when browsing. In parallel a user's prole is aected by user grouping
details, which are constructed by users with similar proles. Assuming that
required information, such as article tagging, keywords to categories match-
ing and articles to categories relation is already part of the meta-portal we present a novel mechanism that can build and maintain a user prole which is
formed without disturbing the user. Furthermore, we describe the real-time
user-centred document grouping mechanism that is implemented to support
the web personalization system and present the experimental evaluation of
the whole system.
