The invention discloses a cross-domain problem
processing method and device based on a large
language model, equipment and a medium. The method comprises the steps that a target problem of a target domain is received; performing
similarity matching on the target problem and a source problem of at least one
source field in an example
pool, wherein the example
pool stores source problems classified according to industries or technical fields, corresponding thinking chains and
source data source fields on which thinking chain reasoning depends; based on the matching result, obtaining or generating a thinking chain associated with the target question; identifying a
source data source field on which the obtained or generated thinking chain associated with the target question depends, and determining a corresponding target
data source field for the target question based on the
semantic similarity; constructing an enhancement instruction based on the obtained or generated thinking chain, the
source data source field and the target
data source field; and inputting the enhancement instruction into the large
language model to generate an answer to the target question. According to the method, the big
language model can generate answers which are logically coherent and reliable in data support.
