I am trying to use the Watson Discovery service to build a virtual customer support agent. We have many documents with tons of Q and A in various formats. In the simplest case, we just have a doc, with an array of:
Q:.. A:...
Q:... A:...
etc. When we upload these PDF files and then try to query it, it returns the full document that included the relevant answer. Is there a way to instruct Discover service, so that it will only return the relevant question and answer pair instead of the full document?
To have Discovery return the individual relevant QA pairs, they should be split up and passed to the service as separate documents. Discovery does not have a method to split a single document on it's own.
If your primary requirement is Q&A, you might probably look into Retrieve-Rank
Discovery is used to deal with complex unstructured data, in your case you have data in a consistent format.
Have a look at this sample app here
