[open-linguistics] Google Refine + RDF export

[hellmann at informatik.uni-leipzig.de]

Hi Steven,
actually it should be me, who bootstraps a list with best practices  
for converting data to RDF, but I am leaving for the jungle/beach in a  
few days until End of March. Last year I was involved in an EU  
Deliverable named Knowledge Extraction from Structured Sources. As a  
result we bootstrapped the Knowledge Extraction Wikipedia Article:
http://en.wikipedia.org/wiki/Knowledge_extraction  which is supposed  
to serve as an entry point for triplification aid.

Also the LATC project (who is responsible for the Google Refine  
extension) has a list with recommended tools , see  
http://www4.wiwiss.fu-berlin.de/latc/toollibrary/

We should not ignore the most basic problem: the lack of open access  
and download links. So first we should draft a list of recommended  
services and guidelines for Linguists to publish their data online. As  
programmers we use GitHub, Bitbucket, Sourceforge or Google Code and  
they are also appropriate for data/ontology projects. Then if it is  
published, we can add it to CKAN and maybe think about licenses and  
privacy and then we can focus on RDF conversion. RDF and Linked Data  
are the last two stars and I think we are having the most problems  
with the first three, currently. We should focus on this and have a  
simple goal: A download link collection of the resources presented on  
the LDL2012 workshop (ignoring data format and licencing issues for  
now ).

All the best,
Sebastian
