Metrology Information Data Push System Based on Crawler and Deep Learning

The National Metrology Data Center has developed a metrology information data push system. The system first uses the web crawler technology to capture the latest metrology information data from authoritative metrology websites at home and abroad. Then the data is integrated to a three-dimensional topic map after being preprocessed by AI and manually curated, which is further published to the website and pushed to the corresponding subscribers with corresponding subject terms. Researchers can subscribe to the information according to the three dimensional topic maps or custom subject terms to obtain the latest metrology information data in real time. The system has been deployed on the website of the National Metrology Data Center, and the actual operation is good, which verifies the feasibility and development potential of the program.
