This paper focuses on information extraction from one site rather than from one page. A new directed-acyclic graph based representation method is introduced for representing link structures on the Web sites. A rule based language is developed for writing extraction rules. The approach is examined and tested on 42 Web sites in six different domains. The results suggest that the system can successfully extract most relevant information from Web sites in different domains.
