Abstract

With the development of science and technology such as the Internet, and the explosive growth of the amount of information, we generate data all the time every day. Obviously we have come to the era of big data. Because we have a sufficiently powerful amount of data, our research can not only be carried out in the main part of the normal distribution, but also makes it possible for the long tail part to become a part of our research. Therefore, data mining is particularly important among them, and it has become one of the main directions of research today. Combined with the current hottest employment issues, this article mainly studies how to use Python, a programming language with a rich language library and powerful computing functions, to crawl the recruitment information process of the largest recruitment website 51job, based on the large amount of information crawled You can find effective information and conduct specific research on employment positions, regions, positions, salary and other directions.
