The invention belongs to the field of intelligent question-answering systems, and relates to a financial intelligent question-answering method and
system based on mixed retrieval and
dynamic query, and the method comprises the steps: constructing an FAQ
library and a financial office
database; receiving a user question, calling a historical chat
record of the user, and calling the large
language model to perform intention recognition; calling a large
language model to perform semantic
rewriting in combination with the real intention of the user to generate a standardized
query statement; obtaining a candidate
list from the FAQ
library by adopting a mixed retrieval mode; if no candidate
questions and answers exist in the candidate
list, replying the standardized answers; otherwise, screening candidate
questions and answers of Top-N, judging whether the candidate
questions and answers of Top-1 are personalized questions or not, if yes, calling a financial office
database to generate a query result, and replying according to the query result and the candidate questions and answers of Top-N; according to the method, semantic retrieval and keyword retrieval are mixed through the user intention
classification result and the conflict detection rule, the candidate
list is obtained according to the mixed retrieval mode, and the retrieval
recall rate is increased.
