Abstract

The invention discloses a relation extraction data set construction method and device and electronic equipment. The method comprises the steps that a plurality of triples with relation types meeting a preset relation type are obtained; collecting an unstructured corpus in the same field as the triple from the target database by using a preset data search method; segmenting the paragraphs in the unstructured corpus according to the paragraph labels and preset types of sentence segmentation punctuation marks to obtain a sentence set, and performing word segmentation operation on the sentence set by utilizing a preset word segmentation tool; matching each statement in the statement set with a head entity and a tail entity in the triple in terms of word granularity; if any statement is matched with the head entity and the tail entity of any triad at the same time, judging that the triad exists in the statement and taking the combination of the statement and the corresponding triad as a marked sample; and when the entity in the triad corresponding to any marked sample is in the target parallel sequence, expanding the statement set by utilizing the entity in the triad.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a relation extraction data set construction method, device and electronic device. Background technique [0002] With the rapid development of Internet technology and the advent of the era of big data, the explosive growth of data, especially unstructured data accounts for more than 75% of them, how to extract effective knowledge from a large amount of unstructured data has become a subject Concerns. Entity relationship extraction technology is a technology that accurately extracts the relationship between entities from unstructured and semi-structured data such as text and web pages. At present, due to the scarcity of data sets and other reasons, the most commonly used method of entity relation extraction technology is the semi-supervised machine learning method based on remote supervision. [0003] Remote supervision assumes that if two entities are...
