Verb focused answering from cord-19

Abstract

At this time of a pandemic turning into an infodemic, it is significant to answer questions asked on the research related to that. This paper discusses a method of answering questions leveraging the syntactic structure of the sentences to find the verb of action in the context corresponding to the action in the question. This method generates correct answers for many factoid questions on descriptive context passages. The proposed method finds all the sentences in the passage, which has the same or synonymous verb as the verb in the question, processes the dependencies of the verbs obtained from the dependency parser and proceeds with further rule-based filtering for matching the other attributes of the answer span. We demonstrate this method on CORD-19 data [3] evaluated with free form natural language questions.
