The World-Wide-Web contains a large amount of information. Everyone can store and retrieve the information from web. It is difficult to find the relevant piece of information from web. Extracting the important information from web is called Web Mining. Web mining technologies are best suited for web information extraction and information retrieval. Web mining is one of the mining technologies, which applies data mining techniques in large amount of web data to improve the web services. We are going to give a brief description of web mining and its categorization namely: web content mining, web structure mining and web usage mining. This paper also reports the web data mining with applications. Keywords: Web Mining, Information Extraction, Information Retrieval, Web content mining, Web structure mining, Web usage mining and Web crawling
