The invention provides a
data annotation method and
system based on an industry word
library and a tag
library in the technical field of
data annotation, and the method comprises the steps: S1, obtaining a large amount of historical
annotation data, and grouping the historical
annotation data based on the industry; step S2, creating an industry word
library and a tag library based on each piece of historical
annotation data; s3, identifying the to-be-labeled file to obtain to-be-
labeled data, and identifying the industry and project numbers of the to-be-
labeled data; s4, through an industry word
bank corresponding to industry matching, the
natural language word segmentation tool performs word segmentation operation on the text data based on industry word segmentation of the industry word
bank to obtain a word segmentation result; matching a corresponding
label library through the item number, and pre-labeling the word segmentation result based on an item
label of the
label library to obtain a pre-labeling result; and S5, after the pre-labeling result is audited and corrected, a labeling result is generated. The method has the advantages that the
data annotation quality and efficiency are greatly improved, and the annotation cost is reduced.
