Abstract

The invention discloses an information extraction method and device and electronic equipment. The method comprises the steps of obtaining a semantic vector of a to-be-extracted text, and predicting a main body element in the to-be-extracted text and first position information of the main body element based on the semantic vector; obtaining a first semantic vector of the main body element from the semantic vector based on the first position information of the main body element; predicting an object element in the text to be extracted and second position information of the object element based on the first semantic vector and the semantic vector of the main body element; according to the first position information and the second position information, extracting a text fragment from the to-be-extracted text to generate structured information of the to-be-extracted text. Therefore, according to the first position information and the second position information, the information can be automatically extracted, manual intervention is not needed, the labor cost is saved, the extraction time consumption is shortened, the accuracy of an information extraction result is ensured, and the efficiency, accuracy and reliability in the information extraction process are improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to an information extraction method, device and electronic equipment. Background technique [0002] In recent years, with the explosive growth of Internet data, various resources have also grown exponentially. Especially for investment research and other fields, it has a huge amount of data. In this case, investment researchers need to obtain relevant factors from massive information to assist in analysis and prediction. [0003] However, the information extraction methods in related technologies often rely on manual extraction, which inevitably leads to technical problems of low efficiency, low accuracy, and poor reliability in the process of information extraction. Therefore, how to improve the efficiency and accuracy in the process of information extraction has become one of the important research directions. Contents of the invention [0004] This appl...
