Abstract

The invention provides a method and device for processing event roles in a text, electronic equipment and a storage medium. The method comprises the steps of encoding words in a text through an encoder in a role processing model to obtain encoding information of the words in the text; performing feature aggregation on the encoding information of the words in the text through an encoder to obtain aggregation features of the text; associating a plurality of upper-layer concepts of at least one event role with the encoding information of the words in the text through an attention model in the role processing model to obtain a semantic vector of the text facing the event role; and classifying at least one semantic vector, facing the event role, of the text and the aggregation feature of the text through a classifier in the role processing model to obtain the event role corresponding to the text. Through the method and the device, the event roles in the text can be automatically and accurately extracted according to the upper-layer concept of the event roles.

Description

technical field [0001] The invention relates to natural language processing technology of artificial intelligence, in particular to a method, device, electronic equipment and storage medium for processing event roles in text. Background technique [0002] Natural Language Processing (NLP) is an important direction in the field of computer science and artificial intelligence, which can realize effective communication between humans and computers using natural language. Natural language processing is a science that combines linguistics, computer science, and mathematics. So this field will deal with natural language, the language that people use every day, so it has a close connection with linguistics. Natural language processing technologies usually include text processing, semantic understanding, machine translation, robot question answering, knowledge graph and other technologies. [0003] The event role processing system is one of the important applications in the field ...
