Some prerequisite reading for your use case:
The first link will describe the AbstractionLayer...:
In your case I think the type you need is "http://s.opencalais.com/1/type/tag/SocialTag"
and the literal is "name"
The second link above will take to a Python example.
If you have a specific coding issue you can try to paste the relevant code here and I will try to help you further.
@Eyal.Kenigsvain, your reply turned out to be useful for me too. I took a bit different path for parsing the response - namely, parsed the JSON file. Although the response gets parsed fine, I have encountered an issue with this _typeGroup : "socialTag". The problem is that companies and organizations are tagged as belonging to this group. As far as I understood, this type presupposes linking its members to URLs rather than giving exact position in text.
This format of output (with no offsets specified) doesn't allow me to map the extracted entity to the text. Do you happen to know if there is a way to get offsets for such entities?
