[Abstract]:With the rapid development of Internet, professional search engines are more and more popular with the majority of users because they can accurately and quickly retrieve the thematic information needed by specific users. However, the maintenance and update of professional search engines takes too much time. In order to overcome this problem, we introduce machine learning mechanism into search engine, and design and implement a professional search engine BERSE, based on machine learning for basic education. The key technology is to track only the subject spider and text classifier of basic education information, so as to speed up the retrieval and updating of information, and has a high recall and precision.
