Given a user query and candidate passages corresponding to each, the task is to mark the most relevant passage which contains the answer to the user query.
The problem is in the domain of Machine Reading Comprehension (MRC). MRC is an area of research in AI which is about answering a question, given a passage of text containing the answer. As search engines evolve to respond to speech inputs and as usage ambient devices like speakers grow in the society etc. returning 10 blue links to a search query is not always desirable. For instance, try searching “what is cricket ball made of” in Bing.com and a direct answer pops up. There is a lot of progress that still needs to be made in this field, and this is one of the exciting areas of research.
I am looking for some state-of-the-art approaches for this problem. Thanks in advance. This is a part of Microsoft's AI challenge 2018 (https://microsoft.com/en-in/campaign/artificial-intelligence/microsoft-ai-challenge-india-2018.aspx)
