Just noticed this as an error with the processing directive inputs;
For "outputFormat" I should have been using "Application/JSON" instead of the 
default "XML/RDF".

Please feel free to disregard this issue.

However, I think it would make sense to include the below line as part of the 
Calais class declaration...

    processing_directives = {"contentType":None, "outputFormat":"Application/JSON", "reltagBaseURL":None, "calculateRelevanceScore":"true", "enableMetadataType":None,"docRDFaccessible":"false"}
