The invention discloses a relation extraction and knowledge graph construction method for text dependency syntactic analysis. The relation extraction and knowledge graph construction method specifically comprises the following steps: step 1, data preprocessing; step 2, pre-defining and extracting an entity; step 3, relation pre-definition and extraction; and step 4, constructing and applying the knowledge graph. The invention relates to the technical field of narrative text processing. According to the method, three models of a time event, a sentence trunk and sentence branches are constructed for a narrative text, specialists in a specific field do not need to formulate a template, mobility is high, a dependency syntax analysis method focuses on a syntactic structure of the sentence, corresponding dependency relationships in the sentence are extracted one by one, and the dependency relationships in the sentence are extracted one by one. And finally, the local dependency relationships are combined according t
