Problems solved by technology
Evaluation objects contain great value. There are many ways to extract evaluation objects from massive evaluation texts in related technologies, such as frequency statistics methods, template rule methods, graph theory methods, natural language basic task models, deep learning methods, etc. , but these methods can only extract clearly expressed evaluation objects from evaluation texts, that is, explicit evaluation objects. For some implicitly expressed evaluation objects, it is difficult to extract them, resulting in incomplete evaluation objects that are difficult to truly reflect. The user's experience with a specific evaluation entity reduces the value of the evaluation object

The invention provides an evaluation object extraction method and device, and electronic equipment. The method comprises the steps: extracting text features of a target text; based on the text features, identifying the type of an evaluation word contained in the target text, and based on the type of the evaluation word, determining a first evaluation object contained in the target text, wherein the first evaluation object is used for evaluating at least one evaluation entity contained in the target text. According to the method, by identifying the type of the evaluation word, extracting the evaluation object implied in the target text and combining with the explicit evaluation object, the more comprehensive evaluation object can be obtained from the target text, the comprehensive evaluation object can truly reflect the experience of a user for a specific evaluation entity, and the value of the evaluation object is improved.
Description
technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to an evaluation object extraction method, device and electronic equipment. Background technique [0002] The evaluation object refers to the subject involved in the evaluation text, which is specifically expressed as the object modified by the evaluation words in the evaluation text, and the evaluation object is used to describe a certain aspect of the evaluation entity. For example, if the evaluation entity is a commodity, the evaluation object of the commodity can be the components, functions, etc. of the commodity; for another example, if the evaluation entity is a certain movie, the evaluation object of the movie can be the script, special effects, etc. of the movie. Evaluation objects contain great value. There are many ways to extract evaluation objects from massive evaluation texts in related technologies, such as frequency statistics methods, templat...
