Hey Yury, You may also want to try Falcons Ontology Search: http://ws.nju.edu.cn/falcons/ontologysearch/result.jsp?query=has+Owner or Falcons Concept Search: http://ws.nju.edu.cn/falcons/conceptsearch/result.jsp?query=has+Owner Cheers, Gong >From: semantic-web-request@w3.org [mailto:semantic-web-request@w3.org] On Behalf Of Juriy Katkov >Sent: Saturday, October 30, 2010 10:40 PM >To: Semantic Web >Subject: How to find a proper ontology for my classes and properties? > >Hello everyone! >I have 2 questions about rdf data. > >1. Suppose I started describing something in triples and I want to use a property 'hasOwner'. I understand that it's much better to use this property from one of the existing ontologies rather than use property from my own namespace. >The question is: what is the easyest and the most right way to search for this property? I know, there is Swoogle and sometimes it helps me with that. I wonder if there is something better that fulltext search. > >2. Suppose I face the dataset I never use before. What do you usually do first to get a first impression about the dataset? At the moment I first make some SPARQL queries to this dataset, such as: >select COUNT(?x) WHERE >{ >?x a ?z . >} > >than I use Marbles or Sig.ma to surf randomly over this data and finally I come up with a opinion where I need data from the dataset or not. >Again, what do you usually do? Is there a tools or useful queries that can help Semantic Web user in browsing data and getting useful info about datasets? > >Thank you in advance! > >Yury Katkov
