Problems solved by technology

Existing information extraction methods are mostly information extraction based on plain text, but for documents such as pdf, there are often complex and diverse formats such as columns, blocks, and nested tables in the document. If you only rely on plain text-based Information extraction will lead to incomplete and inaccurate results of key information extracted

Abstract

The invention provides an information extraction method and device. The information extraction method comprises the following steps: obtaining a to-be-processed document; identifying a text and a table in the to-be-processed document; performing key information identification on the text based on a keyword identification algorithm, and determining document text key information; analyzing characters of cells in the table to obtain key information of the document table; fusing the document text key information and the document table key information, and determining an information extraction result of the to-be-processed document. According to the scheme, not only can the key information of a document text be extracted, but also the key information of a document table can be extracted; in a same to-be-processed document, document text key information and document table key information may be associated, and individual document text key information or individual document table key information may be incomplete, so that the document text key information and the document table key information can be fused to an obtain information extraction result of the to-be-processed document, the information extraction efficiency of the to-be-processed document is improved, and the integrity and accuracy of information extraction can be improved.

Description

technical field [0001] The present application relates to data processing technology in the technical field of artificial intelligence, and in particular to an information extraction method. The present application also relates to an information extraction device, a computing device, and a computer-readable storage medium. Background technique [0002] Artificial intelligence (AI) refers to the ability of an engineered (that is, designed and manufactured) system to perceive the environment, as well as the ability to acquire, process, apply, and represent knowledge. Natural language processing refers to the use of computers to process information such as shape, sound, and meaning of natural language, that is, the operation and processing of input, output, recognition, analysis, understanding, and generation of words, words, sentences, and texts. Realizing information exchange between human and computer is an important issue of common concern in artificial intelligence, compu...
