As an "information company", Amazon not only obtains information from each user's purchase behavior, but also records all the behaviors of each user on its website.
2. Google's intention: If a technology company accurately defines the concept of "big data", it must be Google. According to the data of search research company comScore, in March 2065.438+02, the number of search words handled by Google reached 65.438+0.22 billion. Compared with most other companies, Google's scale and scope give it more ways to apply big data.
3. Target's "data association mining": With the help of advanced statistical methods, merchants can establish a model through the analysis of users' purchase history, predict future purchase behavior, and then design promotional activities and personalized services to prevent users from losing to other competitors.
