The invention provides a data information processing method and system based on visual features. The data information processing method based on the visual features comprises: collecting image-text data based on visual features through a network, conducting data preprocessing on the image-text data to obtain target data meeting a first requirement, conducting big data comprehensive processing on the target data to obtain effective data meeting a second requirement, and establishing an image-text database, updated and/or reset according to the effective data. In this way, a multi-level data cleaning processing process can be realized. By means of the method, the effects of accuracy, integrity, consistency, uniqueness, timeliness, effectiveness and the like can be achieved on the aspect of data. The problems of data loss, inconsistency, repetition and the like can be effectively solved, organic integration of image-text data is finally achieved, a comprehensive image-text database is obtained, and integration and transformation upgrading of the industry are facilitated.
