Thanks all for the support and guidance given throughout the project, it was a great experience working with Stanbol community. > Please feel free to test both solutions.

I guess it is a framework to plugin custom vocabularies and configure disambiguation from those vocabularies? Please correct me if I have got the idea wrong. > 3.
