This is the podcast for the thirteenth class, in which we look at a couple of ways to organize and present information to the user. We see how a term-cloud interface can be created, allowing the user to get a quick glance at the underlying collection. We also talk about a number of clustering algorithms and see how they can be implemented with Lemur.

INLS490-154W: Information Retrieval Systems Design and Implementation

Information organization

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.
