An ontologically driven method and a system for constructing a fish knowledge graph in a target region, including: combing a fish data source in the target region, constructing a fish knowledge ontology in the target region, and collecting text data and image data; according to the fish knowledge ontology of the target region, performing knowledge extraction on the text data, and measuring information content of knowledge extraction results to obtain text information weights; according to the fish knowledge ontology in the target region, performing the knowledge extraction on the image data, and measuring information content of the knowledge extraction results to obtain image information weights; according to the text information weights and the image information weights, matching the first knowledge extraction results with the fish knowledge ontology in the target region, and constructing a multi-modal knowledge graph. The processing accuracy and efficiency of the unstructured fish information can be improved.
