Re: [ontolog-forum] entropy

Hi Paola, 

Please see the message below forwarded from Ravinder Thakur on Linking-open-data
at MIT. Will his problem be addressed in the framework? Does anyone
have suggestions for Mr. Thakur and his collaborators at linking open
data?

Thank you, 

Deborah

Subject: [Linking-open-data] RDF/SPARQL and consistent metadata about content/structure of ontologies

Hi,

 

For the past few days i have been trying to look at RDF/SPARQL from query designing point of view. What basically i have been trying to do is to take very simple /user/ queries ("e.g. Bill Gates net worth") and try to see if i can automatically create the corresponding queriers in SPARQL. The versatile nature of domain of data stored in RDF means that data from every domain would have its own ontology. And the knowledge/understanding of ontology is very much prerequisite to understanding the data based on that particular ontology.

 

This seems a little bit of problem to me. This means that we cannot build queries until we know that structure of ontologies and since there might be thousands of ontologies how are we supposed to know about all the ontologies. Moreover everyday new ontologies will be added to the web.? IS the assumption that the dust will settle after some time and we will have only very few good ontologies about the world ? This seems highly restrictive to me.

 

Obviously I want to write a query processor that is independent on the ontology that the data i am looking on is based upon. I don't want to know pre hand what ontology might correspond to the data i am looking . What i am looking for some consistent way to represent the /METADATA/ about the structure and content about ontologies so that from the metadata about the ontology, i can automatically know about the structure and relevance of the ontology for the query i have in hand.

 

Has anybody faced the problem i have highlighted ? or what i am saying is stupid :) and there is some simple way out there ?

 

 Thanks

Ravinder Thakur

I propose we add 'entropy' as a new dimension

Do I have to write something up? Or are the discussions so far on the
need to model
'change' sufficient?
