Web Mining

Definition
Web mining, an application of data mining is the process of discovering patterns from the web. It can be also stated as the process of analyzing the data or information about a small quantity of data from the web.

Introduction

  • Web mining is the integration of information gathered from the conventional data mining methodologies and techniques to recognize or discover patterns from the large data sets.

  • It involves the parameters of traditional data mining such as clustering, classification, association and examination of sequential parameters.

Types

Web mining is further classified into three types

  • Web usage mining.
  • Web structure mining.
  • Web content mining.

Web Usage Mining

Web usage mining is the process of extracting useful information from server logs. It’s the application of data mining techniques to discover interesting usage patterns from web data in order to serve the needs of web-based applications.

Web Structure Mining

Web structure mining is the process of using graph theory to analyze the structure of a website. It is further divided into two types. 1. Extracting patterns and 2. Mining the structure of the document.
