Consensus building workshop Conference track
Outline • Introduction (ideas behind the track) • Evaluation • Discussion – interesting mappings
Conference track - Features • Broadly understandable domain Conference Organisation • Free exploration by participants within 10 ontologies • No a priori reference alignment • Participants: 6 research groups
Conference track - Dataset OWL, tool Protege
Conference track - Participants • 6 participants • Automs • Coma++ • OWL-CtxMatch • Falcon • HMatch • RiMOM
Conference track - Goals • Focus on interesting mappings and unclear mappings • Why should they be mapped? • Arguments: against and for • Which systems did discover them? • Differences in similarity measures • Underlying techniques?
Outline… • Introduction (ideas behind the track) • Evaluation • Discussion – interesting mappings
Evaluation • Processing all mappings by hand • Assessment based on personal judgement of organisers (consistency problem) • Tags: TP, FP, interesting, ?, heterogenous mapping • Types of errors and phenomena: • subsumption, inverseproperty, siblings, lexical confusion
Evaluation… • Subsumption mistaken for equivalence • Author,Paper_Author • Conference_Trip, Conference_part • Inverseproperty • has_author,authorOf • Siblings mistaken for equivalence • ProgramCommittee,Technical_commitee • Lexical confusion error • program,Program_chair • Relation – Class mapping • has_abstract,Abstract • Topic,coversTopic; read_paper,Paper
Evaluation… • Some statistics as a side-effect of processing
Evaluation… • Distribution of similarity measures • for True Positive Mappings and • for False Positive Mappings
Outline… • Introduction (ideas behind the track) • Evaluation • Discussion – interesting mappings
Discussion • Focus on interesting mappings and unclear mappings • Why should they be mapped? • Arguments: against and for • Which systems discover them? • Differences in similarity measures • Underlying techniques?
