The invention discloses an enterprise scientific and technological achievement
adaptation method based on
big data accurate retrieval and query, and relates to the technical field of
big data processing and knowledge maps, and the method comprises the steps: constructing an enterprise technical field knowledge map based on a standardized multi-
modal feature matrix, receiving incremental technical data in real time by adopting an Apache Flink streaming
processing framework, and carrying out the real-time retrieval and query of the enterprise technical field knowledge map. Dynamically updating a
graph node relationship, removing expired nodes through a
pruning algorithm, and outputting a dynamic
knowledge graph with a
timestamp; and receiving a query request of a user, extracting a query vector by utilizing the cross-
modal embedding model, retrieving a Top-N candidate node
list through a dynamic
knowledge graph, calculating a comprehensive similarity
score in combination with a graph relation weight, and outputting a sorted technical achievement
list. Multi-source heterogeneous data is mapped to a unified
semantic space through a cross-
modal embedding model, and the intelligent level and the actual application effect of scientific and technological achievement
adaptation are comprehensively improved in combination with construction and updating of a dynamic
knowledge graph.
