Abstract

The invention discloses a method and system for radio and television public opinion analysis based on a deep learning technology. The method comprises the process of extraction and identification of public opinion information data based on the deep learning technology: first a data model is generated by repeated learning and training of plenty of material data (including images, videos, voices and optical character recognition (OCR) optical characters), and an image feature library is generated in combination with a computer vision technology (local feature grabbing and matching). To-be-monitored data (including audios, videos and pictures) is obtained from communication media such as cable digital television, wired radio television, satellite television and wireless radio television to serve as input of a deep learning data model, and the established data model is utilized to identify the to-be-monitored data. The plenty of material data forms a characteristic fingerprint database in combination with a computer vision technology, characteristic values of the to-be-monitored data are compared with data in the characteristic fingerprint database, and if the comparison is successful, it is thought that the to-be-monitored data contains public opinion information.

Description

technical field [0001] The invention relates to the field of public opinion monitoring, in particular to a radio and television public opinion analysis method and system based on deep learning technology. Background technique [0002] With the rapid development of network technology and the diversification of radio and television transmission means, radio and television has formed a transmission and coverage network that runs through wireless broadcasting, satellite coverage, cable transmission, and network connectivity simultaneously across the country. The supervision of radio and television has been paid more and more attention by the relevant state departments. Traditional radio and television supervision is mainly limited to signal quality monitoring and broadcast content comparison and verification. Since the supervision has not been fully automated, the manual workload is relatively large. With the development of information technology and the deepening of supervisio...
