This is the podcast for the third class, in which we go through indexing process by first doing tokenization, stop words removal, and stemming manually, and then with the help of Lemur Toolkit.

INLS490-154W: Information Retrieval Systems Design and Implementation

Learning to index

Tools for organizing and accessing information have become indispensable. It is critical, therefore, to understand their design and operational foundations. In this course students will have an opportunity to learn about search engines, web crawling, and some Web 2.0 technologies based on hands-on experience and with a focus on techniques that can be used to access, retrieve, organize, and present information. Students will work with practical developmental tools and learn relevant concepts through experimentation. For instance, students will employ an open source search engine and learn about indexing, retrieving, and ranking techniques.
