Question and answer robot training method capable of intelligently distributing privacy

The invention discloses a question and answer robot training method capable of intelligently distributing privacy. The method comprises the following steps: constructing a data weight of data generated when each user fills in data and uploads the data; preprocessing all chat records in the group by combining a keyword technology preprocessing technology and a data weight to obtain a sentence trunk and a data label of reference data; marking an uploader of the chat record, and uploading the chat record to a block chain as a chat robot training material when the system judges that the difference of privacy attention degrees between the two users who have pairwise chats is large; initializing user credibility according to the difference of privacy attention degrees between the users; and dynamically changing the credibility of the chat record uploader according to the similarity search technology and the scoring feedback of the user using the chat robot on the multi-dimensional scoring request, thereby protectin
