With the rapid development of AI technology, Amazon, Alibaba and other e-commerce leaders have also applied AI to shopping, customer service and other work processes, hoping to speed up the search results and through more accurate product recommendations to stimulate consumption. Ai in the E-commerce application of the outbreak so that online retail giants in addition to continue to meet customer demand, the introduction of automation systems, simplified operations also become a priority investment projects. According to Martech today, British net supermarket Ocado has already used the algorithmic robotics to control the company's logistics, speed up delivery and plan to invest $232 billion in robotics and automation systems, with Amazon spending $5 billion in India alone, Alibaba is planning to invest $15 billion in research and development over the next 3 years, and Forester has predicted that AI-related investments will grow by 300% in 2017. The most popular AI applications include: using chat bots to enhance customer service quality, faster access to search results through image and speech recognition, using advanced algorithms to recommend engines, and increasing the accuracy of product recommendations. Amazon acquired Kiva Systems in 2012 and set up its subsidiary, Amazon Robotics, to develop robotic technology for machine learning, object identification and computer vision. Amazon sales growth of 34% to 43.7 billion U.S. dollars in the 3rd quarter, the product recommended work is not. But the accuracy of the system is not yet up to 100%, but researchers at the University of Toronto predict that once Amazon gets more data, it will be possible to upgrade the accuracy to customers who can directly deliver the predicted goods. AI can also be used against false comments. Product reviews can help with marketing, but they also make it possible to use false comments to sell their products or to discourage opponents. To avoid misuse of the comment mechanism, Amazon has introduced machine learning algorithms to sift through real online commentary. But the development of AI technology has also contributed to the misuse of false criticism because companies can use AI to make comments, and researchers at the University of Chicago found that the use of neural networks to write comments was indistinguishable from human commentary. AI can also be used for styling recommendations, Amazon launched in April 2017 Echo look is a free hand-held camera and personal modeling Assistant, users can voice assistant Alexa under the instructions, camera or video and posted to social media. Cloud computing platform AWS has developed these plans into deep learning tools, such as the chat robot Amazon Lex, Amazon Polly for Cloud text-to-speech services, and the deep learning image analysis technique of Amazon rekognition. Mainland power giant Alibaba is developing its own software commerce Brain Support website's product recommendation, and using instant content consumption, buying behavior and other information, as well as from Alibaba ecosystem such as Alipay, Youku data to build a predictive model. Alibaba's AI technology can help stores match goods and buyers and increase the chances of selling goods. These recommendations are based mainly on the buyer's purchase history, background and location. In addition, Alibaba also launched a word-type chat robot ' shop small ', to help business customers manage virtual stores. In 2015, Alibaba launched the first AI platform in the mainland known as the DT-pai cloud service, allowing enterprises to use a large number of data, analysis of the target market for products, Alibaba in the development phase more planning to use image recognition technology, according to the user took pictures of the product to guide specific pages.
