Conference track goals
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?


Outline1
Outline…

  • Introduction (ideas behind the track)

  • Evaluation

  • Discussion – interesting mappings


Evaluation
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


Evaluation1
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


Evaluation2
Evaluation…

  • Some statistics as a side-effect of processing



Evaluation4
Evaluation…

  • Distribution of similarity measures

    • for True Positive Mappings and

    • for False Positive Mappings
