The invention belongs to the field of
artificial intelligence and
knowledge engineering, and discloses a dynamic knowledge
distillation method and
system based on a
knowledge graph, which are used for extracting and reconstructing high-value knowledge from structured or unstructured documents. Aiming at the existing problems of static
processing, semantic segmentation, recombination stiffness, cross-document association missing and the like, the method realizes dynamic
distillation through the following steps: generating separators in real
time based on
a domain knowledge graph core entity set, breaking through a fixed partitioning rule, and adapting to multi-type document structures; a concept is utilized to trigger a correlation
decision model to filter non-correlation texts, and semantic fragmentization is reduced; loading an adaptive prompt template according to the domain attribute of the
knowledge graph, and fitting the characteristics of the fields of
medical treatment, education and the like; knowledge is dynamically reconstructed through a logic framework defined by a knowledge graph, and cross-document knowledge point
semantic association (such as policy document complementary clause linkage) is achieved. According to the
system, through dynamic blocking, semantic filtering, field
adaptation and logic recombination, the limitation of a traditional technology is solved, the flexibility and field adaptability of knowledge purification are remarkably improved, and the
system is suitable for high-value
knowledge mining and structured output of massive documents.
