Pharmaceutical intelligent information base products to build a medical intelligent library for pharmaceutical companies. The intelligent information base can manage integrated internal and external resources of the enterprise, including internal documents, images, and videos and resources crawled from outside, to form multi-modal intelligent knowledge management. Self-tagging and entity recognition of resource content forms a dynamic and maintainable tag library, and automatically constructs a resource-level knowledge map. Based on knowledge maps and tag information, semantic search, segment-level intelligent knowledge question-and-answer, and personalized push services are possible. The product recently created a large pharmaceutical compliance model based on enhanced knowledge maps. It differs from generic RAG in the form of GraphRag. It realizes intent recognition and standardization of terms based on large models and knowledge maps in user questions, then enhances semantic paragraph retrieval of large models with medical logic in the form of knowledge maps. Finally, the big model sorts paragraphs and optimizes traceability.
