Scenario
Scenario: Sharing of bibliographic metadata in a Peer-to-Peer network Bibliographic metadata is created and maintained in a
decentralized manner Researchers are willing to share their data Use of semantics is crucial in this setting
The Bibster system allows to: Easily share bibliographic data Save work in finding this data Avoid re-typing this data by hand

Semantic Methods in Bibster
Semantic representation and querying of metadata Extraction and classification from e.g. BibTeX files Semantic Web Research Community Ontology and
ACM Topic hierarchy as light-weight ontologies
Peer selection using semantic topologies Scalability requires intelligent query routing Semantic descriptions of peers´ expertise to
build semantic topologies as basis for peer selection Peers with similar expertise are clustered
Semantic duplicate detection Highly redundant and inconsistent representation of bibliographic
metadata Semantic similarity measures to detect duplicates
