Hi,
a short note on DBpedia. As a whole DBpedia provides:
- Data sets for Download
- Web Service for SPARQL (so you can query the data right away)
- A software for parsing Wikis ( about 10-20 developers, all of them volunteers except 2 or 3 ): http://wiki.dbpedia.org/Documentation
- We started to extract data from all Wikipedia Languages: http://wiki.dbpedia.org/Internationalization

Regards,
Sebastian

Hi everyone,
 
This is a follow up on a previous thread (Wikipedia data sets) related to the Wikipedia literature review (Chitu Okoli). As I mentioned in my previous email, part of our study is to identify the data collection methods and data sets used for Wikipedia studies. Therefore, we searched for online tools used to extract Wikipedia articles and for pre-compiled Wikipedia articles data sets; we were able to identify the following list. Please let us know of any other sources you know about. Also, we would like to know if there is any existing Wikipedia page that includes such a list so we can add to it. Otherwise, where do you suggest adding this list so it is noticeable and useful for the community?
