A computer monitoring system is tracking outlandish claims made in commercials Beijing authorities are using computer technology to keep tabs on advertisers who make illegal claims about their products, saving human monitors the task of scanning print, television and radio commercials. The Beijing Industry and Commerce Bureau launched the mainland's first computer-based advertisement monitoring system on Monday. It will sort through 30,000 commercials aired and published in the capital each day. The Beijing Morning Post reported that the system will monitor 26 television programmes, 13 radio shows, three mobile telecommunication companies, and dozens of newspapers, magazines and internet websites. Proponents maintain it will be able to differentiate advertising from editorial, all the time looking for ads that claim a product is the best or better than a rival's offering. Using a database of illegal text and pictures, the system is designed to spot the illicit messages and alert staff. For example, it is designed to detect pharmaceutical advertisements containing the characters for 'number one' or '100 per cent cure rate'. When the characters crop up, they will be highlighted in red, eliminating the need for staff to scan an entire page of advertising. Similar alerts will be issued when television commercials show a person drinking beer, because it is illegal for commercials to display people consuming alcohol. Instances of illegal advertisements will be reported to authorities. The bureau said it detected more than 3,100 illegal advertisements last year. Xinhua quoted bureau chief Zhang Zhikuan as saying people put great trust in advertising and illegal ads were harmful. Ou Shufang , director of the bureau's advertisement department, said the system would be able to spot more than 70 per cent of illegal characters and videos. During a one-month test run, the system monitored 4,796 advertisements and picked up about 100 illegal examples. In Beijing, there are 10,471 advertising companies, employing more than 100,000 people. About 2.5 billion yuan is spent each year on promotions.
