Embodiment Construction

[0059] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein.

[0060] Unstructured data: The data structure is irregular or incomplete, there is no predefined data model, and it is difficult to express the data with the two-dimensional logic table of the database. It cannot be clearly expressed with a unified structure, so it is difficult to follow a unified model. Information structuring and information extraction.

[0061] BERT model: Bidirectional Encoder Representations from Transformer, which is a bidirectional encoder representation based on Transformer. BERT uses Transformer, and when processing a word, it can also consider the words before and after the word to get its meani...

Abstract

The embodiment of the invention relates to the technical field of data processing, and discloses an information extraction method, device and apparatus and a computer readable storage medium, and the method comprises the steps: obtaining to-be-extracted data; determining a word vector matrix corresponding to the to-be-extracted data; determining head entity prediction information according to the word vector matrix and a head entity prediction model; determining intermediate word prediction information according to the word vector matrix, the head entity prediction information and an intermediate word prediction model; determining triple information contained in the to-be-extracted data according to the word vector matrix, the head entity prediction information, the intermediate word prediction information and a tail entity prediction model; wherein the triple information comprises position information and grammatical relations of the head entity, the intermediate word and the tail entity. By means of the mode, the accuracy of information extraction is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to an information extraction method, device, equipment, and computer-readable storage medium. Background technique [0002] How to extract information from massive unstructured data and convert it into structured information is the main problem solved by information extraction technology. Relational extraction is an integral part of information extraction, which aims to determine whether there is a semantic relationship between entities. It includes technologies such as data mining, machine learning, and natural language processing. Has a wide range of applications. [0003] In the process of implementing the present invention, the inventors found that most of the existing relation extraction methods rely on predetermined relation systems, and corpus labeling and model training are performed according to these relations, which are suitable for ...
