PCI: Plants Classification & Identification Classification of Web pages for Constructing Plants Web-Directory

Despite the growth of the web in recent years, some portion of the web remains largely underdeveloped, as shown in lack of high quality contents. An example is the botany specific web directory, in which lack of well-structured web directories have limited user's ability to brows the necessary information. In this research we propose a improved framework for constructing a specific we directory. In pervious study web directory has been constructed by automatic component and filtered by experts. Our interest is to improve automatic component by using dynamic threshold for crawling. It also has been shown that manifold ranking is not useful in some domain like botany.
