RSS (Really Simple Syndication) is a format for describing and synchronizing website content, and is the most widely used XML application. RSS has built a technical platform for rapid information dissemination, making everyone a potential information provider. After publishing an RSS file, the information contained in the RSS feed can be directly called by other sites, and because the data is in standard XML format, it can also be used in other terminals and services. It is a kind of description and synchronization. The format of website content. [1] RSS can be one of the following three interpretations: Really Simple Syndication; RDF (Resource Description Framework) Site Summary; Rich Site Summary. But in fact, these three explanations all refer to the same Syndication technology.

Word segmentation is the process of recombining continuous word sequences into word sequences according to certain specifications. We know that in English writing, spaces are used as natural delimiters between words, while in Chinese, words, sentences and paragraphs can be simply delimited by obvious delimiters, but words do not have a formal delimiter. , although English also has the problem of dividing phrases, but at the word level, Chinese is much more complex and difficult than English.
