Abstract

The invention relates to the technical field of artificial intelligence, and particularly discloses a triple information extraction method and device, electronic equipment and a storage medium, and the method comprises: performing semantic segmentation on a to-be-extracted text to obtain n words, wherein n is an integer greater than or equal to 1; according to the n words, performing semantic information extraction on the to-be-extracted text to obtain a semantic vector of the to-be-extracted text; determining a main entity word in the n words according to the semantic vector; according to the main entity word and the semantic vector, determining guest entity words corresponding to the main entity word in remaining words, wherein the remaining words are all words except the main entity word in the n words; determining a relation word between the main entity word and the guest entity word according to the main entity word, the guest entity word, the semantic vector and a preset relation database; and taking the main entity words, the guest entity words and the relational words as triple information of the to-be-extracted text.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a triplet information extraction method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of big data technology, massive heterogeneous or unstructured documents that were difficult to use, such as various WEB pages, office documents, PPT, etc., have been paid attention to. Therefore, structured mining of unstructured texts is becoming more and more important, and information extraction is an important means of mining information. At present, information extraction has been able to extract the category of triples with a certain relationship from the text, which is often expressed in the form of (S, P, O). Among them, S means Subject, which means the main object; P means Predict, which means the relationship; O means Object, which means the passive object. [0003] The traditional triple inform...
