Presentation Transcript

  1. Consensus building workshop Conference track

  2. Outline • Introduction (ideas behind the track) • Evaluation • Discussion – interesting mappings

  3. Conference track - Features • Broadly understandable domain Conference Organisation • Free exploration by participants within 10 ontologies • No a priori reference alignment • Participants: 6 research groups

  4. Conference track - Dataset OWL, tool Protege

  5. Conference track - Participants • 6 participants • Automs • Coma++ • OWL-CtxMatch • Falcon • HMatch • RiMOM

  6. 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?

  7. Outline… • Introduction (ideas behind the track) • Evaluation • Discussion – interesting mappings

  8. 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

  9. 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

  10. Evaluation… • Some statistics as a side-effect of processing

  11. Evaluation…

  12. Evaluation… • Distribution of similarity measures • for True Positive Mappings and • for False Positive Mappings
