INTELLIGENT QUESTION ANSWERING METHOD AND APPARATUS FOR MULTI-ROUND DIALOG IN MEDICAL FIELD, AND COMPUTER DEVICE

摘要

An intelligent question answering method for multi-round dialog in the medical field. The method comprises: acquiring an Nth question description statement; inputting the Nth question description statement into a natural-language understanding model, and extracting entity information and intention information; and if no entity information or intention information is extracted, taking the entity information or the intention information in an (N-1)th question description statement as the entity information or intention information, so as to perform completion to obtain a completed question description statement, and outputting a dialog answer. According to the method, extracting entity information and intention information of a previous round of dialog can better simulate human communication, so that even if a user uses a demonstrative pronoun or hides some entities or intentions, the dialog can still be made more natural and smooth by means of inheriting context, and the user experience is better. The method further relates to blockchain technology, and the intelligent question answering method for multi-round dialog in the medical field is realized in a blockchain.
