Extraction of user specified web knowledge using Spatial Data Mining

Nowadays the World Wide Web has becoming one of the most comprehensive information resources. It probably, if not always, covers the information need for any user. Those differences make it challenging to fully use Web information in an effective and efficient manner. Web mining is the application of data mining techniques to extract knowledge from web data including web documents, hyperlinks, log usage of website etc. In this paper we extract data from web using spatial data mining. Spatial data mining is the process of trying to find patterns in geographic data. Spatial data mining is the application of data mining techniques. Spatial data mining follows along the same functions in data mining, with the end objective to find patterns in geography. In this paper we provide an introduction of spatial data mining as well as web. Then we focus on how data is extracted from web using some preprocessing techniques or some steps. It describes a method to extract useful information from a web page using spatial data mining. We are extracting hyperlinks and email from single and multiple websites that’s why it is using spatial data mining because in spatial mining data is extracted from different locations. Different websites will have different web servers means different locations. This method includes some preprocessing steps to extract information. That extracted information will be knowledge.
