Abstract

The invention discloses a text information extraction method and apparatus. The method comprises steps of obtaining a text feature vector corresponding to a to-be-processed text; dimension transformation being conducted on the text feature vectors according to the number of preset information features, and an information candidate vector matrix including the number of dimensions being obtained; traversing the information candidate vector matrix, and determining the position information of a character feature vector conforming to the preset information feature in the information candidate vector matrix; characters being extracted from the text to be processed according to the determined position information, and the information to be extracted being obtained according to the conformed preset information features. According to the method, the information candidate vector matrix can be constructed, and the position information of the character feature vectors conforming to the features ofthe information to be extracted in the information candidate vector matrix is determined by traversing the information candidate vector matrix. According to the method, automatic and efficient extraction of the information is realized, and a large amount of information meeting requirements can be conveniently obtained from the to-be-processed text.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a text information extraction method and device. Background technique [0002] Information Extraction (IE, Information Extraction) is a text processing technology that extracts factual information such as entities, attributes, relationships, and events from natural language texts. It is an important basis for artificial intelligence applications such as information retrieval, intelligent question answering, and intelligent dialogue. wide attention in the industry. Information extraction tasks involve complex technologies such as entity recognition and relationship classification, which are extremely challenging. At the same time, using information extraction methods to extract effective triplet information from natural language texts is the core step in building knowledge graphs. [0003] Traditional information extraction methods have low operating ...
