The invention discloses a multi-
modal data dynamic
reasoning system and method based on a
cognitive map, and relates to the technical field of map
data management.The method comprises the steps that text, voice and image
data input by a user are extracted, user data are analyzed, and a structured interaction
record is generated in combination with a
user identifier and a
timestamp; analyzing historical interaction records, detecting continuous query events of the same user for similar questions, gathering
negative feedback signals, analyzing repetition frequencies of
repeated events in the used user, and analyzing feedback intensity coefficients of output repeated behaviors; positioning corresponding nodes in the
cognitive map according to the repeated behavior characteristics, analyzing attenuation coefficients, activating associated alternative reasoning paths, and outputting a to-be-updated node set and candidate paths; and adjusting the node weight based on the
attenuation coefficient, updating the weight according to the semantic relevancy of the candidate path, updating the atlas connection relationship, and outputting the optimized cognitive atlas. Abnormal conditions are identified, the
knowledge graph node weight is adjusted, and the analysis accuracy is improved.
