Yes/No and List answers #57

Open Johntec opened 8 years ago

Johntec commented 8 years ago

Hi,

I would like to ask if it is possible to add functionality for yes and No questions? ex: is Florida in America ? Yes

And to see a list of answers which have the same weight for an question, ex: who are the children of Peter? Jan in A son of Peter, Mike is the son of Peter.

and how we would change the Sparql to search for items in Blank nodes?

Thank you!

I have thought about this for some time and it's not totally straightforward to insert in YodaQA. It seems to me that the strategies for answering such questions will be quite different. A most straightforward way would be to rephrase a yes/no question to (a set of) factoid question and then try to match the answers to the fact mentioned in the question... research efforts in this area are welcome!

Regarding list answers, we are working on this actively. @pichljan is checking whether we could improve F1 score by having a dummy "don't know" answer, then its position in the answer candidates list could naturally determine a list cut-off point.
