What kind of service is Watson Question and Answer?

This service uses Watson, IBM's cognitive computing system, and provides the appropriate response to inquiries in natural languages about a particular area of knowledge.

At this time, we can leverage the knowledge base (corpus) in two areas: Travel, Healthcare, and return answers after understanding the meaning of the pawn in the natural language.You can send a question through the API and receive an answer.

Results include candidate answer statements, credit scores, and links to the source of information on which the answer was based.

Currently, we only support English, and as mentioned above, we only support Travel and Healthcare.

Please refer to the following for usage and usage samples.
