The web has become an important medium to conduct business, communicate ideas and entertainment. It is essential to collect data from various data sources. The process of finding quality and useful information is tedious and a frustrating experience. Assembling and managing data from various sources produces reliable database in data warehouse. Data mining techniques are used in web mining applications to find interesting and potentially useful knowledge from web data. Data mining tools can mine the required information from mass web data and it is helpful for organizations to improve work efficiency. The aim of this paper is to give overview of web data mining categories and some of its applications.
