Dear Dimitris,
I'm happy to hear that more work will be invested into a reorganization of the
DBpedia ontology. As you might know, together with Magnus we have already
invested some thoughts (and publications) into the topic with the focus on data
cleansing based on an improved DBpedia ontology.[1,2] Unfortunately, Magnus
and I will not be able to participate live at the Dublin Meeting in Feb 9.
Nevertheless, we would like to contribute.
From our perspective we would like to apply the DBpedia ontology to detect
inconsistencies and flaws in DBpedia facts. This should not only be possible in
a retroactive way, but should take place much earlier. Besides the detection of
inconsistencies during the mapping process or afterwards in the extracted data,
this could already be possible right from the start when the user is changing
the wikipedia infobox content (in the sense of type checking for domain/range,
checking of class disjointness and further constraints, plausibility check for
dates in connection with basic axioms to be defined, etc.). Another possibility
would be a tool that makes inconsistencies/flaws in wikipedia data visible
directly in the wikipedia interface, where users could either correct them or
confirm facts that are originally in doubt. To achieve this, not only a
formally sound and semantically enrichedDBpedia ontology including a set of
basic axioms would be necessary, but also the applications and infrastructure
that make use of the ontology.
Also the relation of the DBpedia ontology to other ontologies would be a rather
interesting topic. This includes the already proposed schemata (schema.org,
facebook OG, etc) as well as established ontologies (yago, umbel, etc...) where
mapping to DBpedia entities already exist. Can we make use of these ontologies
(and existing mappings) to complement DBpedia ontology in som (semi-)automated
way?
Thanks and best regards,
Harald
