Map frames and FEs to DBPO properties #64

Closed marfox closed 9 years ago

marfox commented 9 years ago

For each frame and FEs in our current definitions, try to find a suitable mapping to a DBpedia ontology property. If it doesn't exist, it may indicate that our approach found a new property, which can be proposed for addition. Otherwise, it would help to assess the knowledge base increase impact on already available properties.

I only found 7 mappings out of 22 items (frames + FEs).

The main DBPO issues preventing from finding a mapping are:

  1. Too many DataType properties, instead of Object properties. The labels may match, but the range are always literals, and we want entities;
  2. Too specific labels, e.g., stateOfOriginTeam, teamCoached, youthClub, continentalTournament, nationalTournament etc.;
  3. No suitable domain/range constraints.

The table below reports a recap of the findings:
