Abstract

The invention discloses a chemical information extraction method and device, equipment and a storage medium. The method comprises the steps of obtaining a chemical document, separating an image and a text from the chemical document, extracting a chemical structure and a label used for labeling the chemical structure from the image, establishing a mapping relation between the chemical structure and the label to obtain first storage information, extracting chemical entities and an incidence relation between the chemical entities from the text, and obtaining second storage information; and obtaining second storage information, and storing the first storage information and the second storage information in a chemical database. According to the technical scheme, chemical documents can be automatically scanned, structured data can be extracted from unstructured or semi-structured data, data management is facilitated, and great help is provided for scientific research, production and experiments in the chemical industry. In addition, manual operation is not needed, so that the labor cost is saved, input errors are reduced, and the data updating speed is increased.

Description

technical field [0001] Embodiments of the present invention relate to chemical information technology, and in particular to a method, device, equipment and storage medium for extracting chemical information. Background technique [0002] Accurate chemical data management is essential for cheminformatics. Today, researchers or discovery software can access internal or external public databases to retrieve the necessary information, although the main source of knowledge is the scientific literature. However, since the information in the literature is unstructured or semi-structured, it is written in natural language. Chemical structures are embedded as images in reports, journals and patents. These cannot be entered directly into chemical databases or chemical software. Copying information manually is time-consuming and error-prone. Furthermore, the rapid growth of publications makes it difficult to maintain up-to-date datasets. Contents of the invention [0003] The in...
