Write a short note on WWW Mining (and its advantages).

WWW (web) mining is the use of data mining techniques to discover useful information and knowledge from the World Wide Web: from page content, hyperlink structure and usage logs.

Types

Web mining -> Content mining | Structure mining | Usage mining
  • Content mining: text, images and multimedia in pages (classification, clustering, summarisation).
  • Structure mining: link graph analysis (PageRank, HITS).
  • Usage mining: web log and click-stream analysis for user behaviour (association rules, sequential patterns).

Process

Resource finding (retrieval of pages) → information selection and pre-processing → generalisation (pattern discovery) → analysis and validation.

Advantages

  • Helps to find relevant information from a huge, unstructured web quickly (search and ranking).
  • Personalisation and recommendation to individual users, better user experience.
  • Gives businesses insight into customers for targeted marketing, cross-selling and improving sales.
  • Helps improve web site design and navigation, and server performance (caching, load balancing).
  • Detects fraud, spam and intrusions.
  • Supports social network analysis and opinion mining, and the discovery of new knowledge from web data.

Challenges

Huge, dynamic and unstructured data, noise and quality, privacy concerns.
