Personalization in the EPOS project
Proceedings of the Semantic Web Personalization Workshop at the ESWC
2006 Conference, page 42 - 52. (2006)Abstract
In this work we present the results of the EPOS project
with regard to the needs of personalization in the Semantic Web. Focus
of this work is the subjective view of an individual person, expressed
in a
Personal Information Model (PIMO). It is matched both with personal
resources (files, e-mails, and websites) of the user and organizational
knowledge (ontologies). A user observation component gathers actions
of the user to calculate the current context with regards to current
goals
and matching elements in the user’s PIMO. Combined, the representation
of the user’s stored information and the current context provide a
thorough representation of the user. Desktop applications can use
this
representation to provide personalized services. Three special purpose
applications were implemented: a search engine, a context-sensitive
assistant,
and a tool for filing new information. An evaluation of this approach
showed that it increases productivity and indeed reflects the subjective
view of users. Also, the approach satisfies most of the requirements
of
an Adaptive Educational Hypermedia System AEHS. Parts of this work
are published as open source projects.
