Abstract

The embodiment of the invention discloses an inundation sub-domain identification method and system, and relates to the technical field of computers. The inundation sub-domain identification method and system are applied to search engines. Inundation sub-domains are identified according to the dispersion or the concentration ratio of the fragment length of any valid fragment set of sub-domain names, and the identification degree of the inundation sub-domains can be effectively improved. The inundation sub-domain identification method in the embodiment includes the steps of collecting sub-domain names with the same main domain name, and if it is judged that the fragment length of any valid fragment set of the sub-domain names with the same main domain name is in dispersed distribution or concentrated distribution, identifying that the sub-domain names corresponding to any valid fragment set are the inundation sub-domains, wherein the valid fragment set is the same fragment set of a left-side domain name part and a right-side domain name part of the same-stage fragment in a same-stage fragment of the sub-domain names with the same main domain name.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for identifying flooded subdomains. Background technique [0002] The development of computer network technology has greatly improved the convenience for people to obtain information. There are massive amounts of information stored in computer networks. In order to enable people to find the information they need, search engines are widely used. Search engines include websites, Quality control is based on subdomains. Sub-domain names refer to multiple domain names extended by the webmaster on the basis of the main domain name according to different businesses. For example, bbs.163.com provides forum services, and blog.163.com is a sub-domain name of NetEase Blog. The subdomain name can be named arbitrarily, and it can even be a multi-level subdomain name, such as twocold.blog.sina.com.cn. The subdomain name is composed of the left part of the domain name pl...
