It discusses research performed within the project 'Semantic Methods and Tools for Information Portals (SemI-Port)'. 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.enText/Conference Paper1617-5468
