Today digital libraries provide access to a vast, but lar-gely unstructured, amount of document collections.Facing the ever increasing challenge of the informationoverload content providers have to focus on new waysin user-centered retrieval, not only providing tools forsearching information, but tools for personalizing,managing, evaluating and working with the returnedsearch results.Within the ViFaChem II research project the TIB and

the L3S Research Center, Hannover, have developed anenhanced retrieval platform for chemical digital libraries.The prototypical interface processes full text and bib-

liographic metadata collections to create semanticallyenriched document collections with chemical metadata.Processing steps include text mining for chemical enti-ties, reaction types and chemical structure reconstruc-tion. However, the ViFaChem digital library does notonly offer the classical document access via a text orchemical structure search, but also semantic searchbased on the faceted browsing paradigm. In particular itincludes the Semantic GrowBag algorithm, which auto-matically creates facets for navigational access and queryrefinement using the relationship between documentsand author keywords. Based on higher-order co-occur-rences of keywords in documents these graphs hier-archically arrange all related topics dynamically withrespect to the underlying content collection. Having dif-ferent personal views on the document collection theuser now can search and navigate through search resultsusing individual retrieval strategies. Facets for chemicalreactions, chemical entities or topics combined with anunderlying ontology thus allow a semantic driven accessto documents.Combined with Web 2.0 features the interface of

ViFaChem II provides the user with a new experience in

searching large document collections, where the usercan navigate through query results based on his perso-nalized knowledge space.
