Abstract

The embodiment of the invention discloses a text data relationship extraction method, device and equipment and a readable storage medium. The method comprises the steps of obtaining text data with a keyword tag; constructing sentences according to the keyword tags and a predetermined entity relationship, and taking the sentences and text data as input data of a reading understanding model; and judging whether an answer output by the reading understanding model is a correct entity in the text data or not, and if so, marking the two entities and an entity relationship in the text data. Accordingto the technical scheme, sentences formed by keyword tags and predetermined entity relations and text data serve as input data of a reading understanding model, whether answers of the reading understanding model to the sentences are correct entities in the text data or not is judged, and if yes, the entities in the text data and the entity relations are marked; the problem of lack of training corpora in the application field of relation extraction is solved, and the cost is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of natural language processing, and in particular to a method, device, device and readable storage medium for extracting relations of text data. Background technique [0002] In the field of natural language processing, relationship extraction usually refers to the connection between entities in the text, such as grammatical relationship, semantic relationship, etc., and the relationship between entities is usually described as a relational triple <E1, R, E2 >, where E1 and E2 refer to the entity type, and R refers to the relationship description type. The main purpose of entity relationship extraction is to identify and determine the specific relationship between entity pairs from natural language texts. After the text undergoes two data preprocessing processes, named entity recognition and keyword recognition, the determined triplets <E1, R , E2> stored in the database for further ana...
