Many high-valued free academic papers on the web are obscured by the large amount of other types of information because of the lack of a more pratical and specific tool for the retrieval of this type of documents.The study analyzes the characteristics of academic document pages and verifies the differences between the academic document pages and the non-academic pages.It found that the academic document pages could be distinguished from other web pages by their differences in keyword frequency,page total links and the proportion of related links.Those differences may be applied in the automatic identification of Chinese academic papers on the web.
