A study of different web-crawler behaviour

摘要

The article deals with a study of web-crawler behaviour on different websites. A classification of web-robots, information gathering tools and their detection methods are provided. Well-known scrapers and their behaviour are analyzed on the base of large web-server log set. Experimental results demonstrate that web-robot can be distinguished from human by feature analysis. The results of the research can be used as a basis for comprehensive intrusion detection and prevention system development.
