A weak fuzzy description logic with aggregation


  • Peter Vojtáš, KSI MFF UK Praha

In semantic web a query can contain several vague concepts of user’s preferences. This particular preferences need to be combined to get an overal ordering of results. We discuss extensions of description logic with existential restrictions and fuzzy aggregation. We give some motivating examples, discuss formal models, possible extensions of OWL and implications to web services.
