I have been quiet of late as I have been working on a Open Calais parser tool to enable people to work effectively with open calais output - the output is fairly complex RDF and my little tool should allow quick extraction of terms and values so you can plug open calais into your .NET apps etc. Its been a sharp learning curve in terms of how RDF works (and how to parse it) but the results now are working rather nicely.
I felt some of the other taggers / parsers let a lot great data slip by as they were just concentrating on the tags (which is fine and is probably what you want) but there can be a lot of rich relationships stored in the documents (such is the joy of RDF) and I wanted to enable people to get at that data if they wanted (which is why it took so bloody long hehe)
Quick sneak preview as you can see .. all entities resolve to real .NET objects populated with all the data and values.
It is on the sanity check stage and I will post some info about it very soon (I am tempted to write a live writer plugin but I think thats me getting disctracted and I just need to get the core thing finalised).
This may all be pointless work and Ive spent too much time getting it to extract data no one wants but it turned into a personal challenge so I had to finish it hehe :P
