8. A service consultation platform intelligent management system as claimed in claim 7, characterized in that: The semantic similarity matching algorithm includes parsing the semantics of user input through a multi-head attention mechanism, and combining image features, time decay weights and user portrait information to fuse multimodal data to construct a user demand representation. At the same time, in the semantic matching process, a similarity calculation method is used to improve the matching accuracy based on text content and combined with graph relationships and context information in the knowledge base. The semantic association between items is optimized through the graph neural network GNN, and context-aware similarity is introduced to aggregate the semantic information of the neighborhood of the knowledge base. The entries in the knowledge base are prioritized through a multi-factor scoring mechanism, and the historical usage frequency, expert ratings and time decay factors of the entries are comprehensively considered. The comparative learning method is used to optimize the answering process to ensure that the system can select the knowledge entries that best match user needs.
