The application discloses a kind of structured
knowledge extraction method,
system, equipment and storage medium of automobile
software design document, the method includes: to automobile
software design document is carried out format conversion and area division, obtains structured data block set;Through sequence mark model,
named entity recognition and type mark are carried out to text type data block, and obtain
entity type label list;According to preset automobile
software relationship rule, generate multiple groups of entity candidate relationship pairs according to
entity type label list;According to text type data block,
relationship extraction is carried out to each group of entity candidate relationship pairs by graph neural network, to generate relationship triple set;
Entity type label list, relationship triple set, the structured information in text type data block is stored.The present application is sequentially linked by the steps of file analysis, entity recognition,
relationship extraction and data storage, effectively solves the problem of intelligent extraction structured knowledge from automobile software multi-
modal design document.
