Abstract

The invention provides a method and device for extracting elements in a chemical reaction flow chart, and the method comprises the steps: obtaining a target image which comprises the chemical reaction flow chart; element information is extracted from the chemical reaction flow chart through a pre-trained extraction model, and the element information comprises types and coordinates of elements. Compared with the prior art that whether the target image contains the target element or not is determined on the basis of a predefined reference shape, the method has the advantages that the element information is extracted from the target image through the extraction model to determine whether the target image contains the target element or not, the accuracy of element extraction is greatly improved, and generalization is good.

Description

technical field [0001] The present disclosure relates to the technical field of chemical informatics, and in particular, to a method and device for extracting elements in chemical reaction flow diagrams. Background technique [0002] In electronic publications such as journals and patents, organic chemical reaction formulas are usually expressed in the form of reaction flow diagrams, which may contain arrows (such as unidirectional arrows, multi-directional arrows, etc.), indicators and other elements. The elements of , have a certain impact on the accuracy of subsequent extraction of chemical reaction formulas from electronic publications such as journals and patents. [0003] At present, there is a method for identifying arrow elements: a reference shape is pre-defined for a specific element, and after that, it is detected whether the specific image contains the pre-defined reference shape, and then it is determined whether the specific image contains the specific element....
