The special action of "Clear Network Platform Algorithm Typical Problem Governance" is being carried out, and it is clearly required to focus on rectifying and using algorithms to implement big data "killing" and other issues. For some time, many consumers have been inadvertently "calculated" by the algorithm, and special actions have sent a signal to resolutely rectify this chaos. Algorithms quietly affect daily consumption patterns. The algorithm not only promotes the development of digital economy efficiently and accurately, but also erodes consumers' rights and interests in the form of big data "killing". Nowadays, the algorithm may know more about my consumption habits than consumers. Different people book the same flight and the same cabin ticket at different prices. After an APP is used many times, it can no longer receive a large amount of coupons, but it is more expensive for members to book hotels ... As the algorithm is deeply embedded in daily consumption, the "killing" method of big data is refurbished, becoming more and more hidden and complicated. "Killing customers" infringes on consumers' right to know and choose. Algorithms must be law-abiding. Pricing should be based on honesty, and the platform cannot "tailor-made" the price for consumers according to "user portraits" such as age, occupation and consumption level. The so-called "algorithms" that harm the legitimate rights and interests of consumers and undermine the normal and fair competition order in the market must be severely cracked down according to law. Algorithms are not profit-makers. The "killing" of big data is a technical problem and a procedural problem on the surface, but it is actually a social problem and a credit problem. Behind the algorithm is the value choice of the enterprise. Perhaps the cleverness and calculation of "random discount" can bring short-term benefits to business expansion, but in the long run, it will continue to erode the trust of consumers and damage the corporate image, which will lay a disaster for the sustainable development of the whole industry. The algorithm should be good. The use of the algorithm should find an appropriate balance between technological progress and ethical norms, and continue to explore the establishment and improvement of a normalized supervision mechanism. Properly protect users' privacy and experience, rebuild trust with consumers, and make good use of the platform of the algorithm to achieve long-term results. The application of new technologies will bring new products and new formats, as well as new impacts. "Clear network platform algorithm typical problem management" is not a gust of wind, but to continue to let everyone really feel the convenience of new technology. (Xinhua News Agency)
