Applications of near infrared spectroscopy(NIRS) and the applied research and practice of “NIRS+Internet” mode in the field of tobacco are reviewed in this paper.In the network environment,influences of the NIRS equipment differences and the shortcomings of common chemometrics method(algorithms) in modeling and data processing on the deep applications of NIRS are briefly discussed,and the possible solutions for cloud computing of NIRS are proposed.Finally,the application prospect for NIRS networking in big data period is also outlooked.
