The paper describes a set of approaches for representing and
accessing information within a semantically structured information
portal, while offering the possibility to integrate own
information. It discusses research performed within the project
`Semantic Methods and Tools for Information Portals (SemIPort)'.
In particular, it focuses on (1) the development of scalable
storing, processing and querying methods for semantic data, (2)
visualization and browsing of complex data inventories, (3)
personalization and agent-based interaction, and (4) the
enhancement of web mining approaches for use within a
semantics-based portal.
