1. Introduce students to the basic concepts and techniques of Information Retrieval, Web
Search, Machine Learning for extracting knowledge from the web.
2. Develop skills of using recent data mining software for solving practical problems of
Web Mining.
3. Gain experience of doing independent study and research.
Outcomes:
After the course is completed student should be able to:
1. Describe key concepts such as web log, hypertext, social network, information
synthesis, corpora and evaluation measures such as precision and recall.
2. Discuss the use of methods and techniques such as word frequency and co-occurrence
statistics, normalization of data, machine learning, clustering and vector space
models.
3. Analyze and explain what web mining problems are satisfiably solved, what is
worked upon at the research frontier and what still lies beyond the current state-ofthe-art.
