Abstract

The invention discloses a question and answer processing method and device, a language model training method and device, equipment and a storage medium, and relates to the field of natural language processing. The specific implementation scheme is as follows: obtaining at least one candidate table matched with a to-be-queried question, wherein each candidate table comprises a candidate answer corresponding to the question; processing the at least one candidate table to obtain at least one table text, the table text comprising text content of each domain in the candidate table, the domains comprising titles, headers and cells; respectively inputting the question and each table text into a preset language model to obtain a matching degree of the question and each candidate table; according to the matching degree of each candidate table, outputting a reply table, wherein the reply table is a candidate table of which the matching degree with the question is greater than a preset value or acandidate table corresponding to the maximum matching degree in the at least one candidate table. The language model is adopted to perform semantic matching on the questions and the texts, so that the matching accuracy and recall rate of the questions and the tables are improved.

Description

technical field [0001] The embodiments of the present application relate to natural language processing technology in data processing, and in particular to a method, device, device and storage medium for question answering processing and language model training. Background technique [0002] Question Answering System (QA) is an advanced form of information retrieval system, which can answer questions raised by users in natural language with accurate and concise natural language, and provide users with personalized services. When the question answering system answers the user's question, one of the ways is to match the question with a structured answer, such as an answer in the form of a table. However, how to obtain the table corresponding to the question is currently a major difficulty. [0003] At present, the question system mainly processes the information of each field in the table (including title, table header, table unit and context, etc.), and then text-matches the ...
