Import Possible Answer Units into Watson Discovery

Question

I have a follow up question off of the question here:

How to get exact answers instead of the whole document using Watson Discovery?

One of the answers mentioned using the Document Conversion Service to create Possible Answer Units (PAUs) within my document. When I do this and upload this large JSON file that contains all of the PAUs, Discovery still returns the entire document that contains all of the PAUs, which I guess is expected.

To complete the solution, I assume I would have to break down each individual PAU into its own document. Does Discovery have a built in tool to do this, or do I need to write my own script?

(Ideally the script would contain some reference to the original file name/metadata and maintain the hierarchical structure that the Document Conversion Service created from my Header definitions)

Watson Discovery doesn't provide the service of giving some section of document as an answer to your query.

If you have such things in your mind, I would suggest you to use Retrieve and Rank service, which basically helps you to train watson and to get expected answer section from your provided documents.

Note: R&R service uses Document Conversion service internally

Thank you for answering, but this doesn't really answer my question. I understand the Retrieve and Rank tool is more apt for my situation currently. However, I would like to use the Discovery tool since it is the tool that will be getting more strategic focus and improvements. I imagine in the coming months there will be a lot of improvements and new features. I would like to take advantage of them as they come. With that in mind, I am trying to implement a work-around and was wondering if there is a built in utility to do so. In my research I haven't found one. Are you aware of any? – Tom J May 19 '17 at 19:52

Now you can use the new passage retrieval feature to do that. It is available as "Include matching passages" in the WDS tooling or in the API reference

Passages query boolean A boolean that specifies whether the service returns a set of the most relevant passages from the documents returned by a query. The default is false.

Note: The passages parameter works only on private collections. It does not work in the Watson Discovery News collection. "
