This is the podcast for the eighth class, in which we start looking at one of the core components of IR - evaluation. We begin our discussion by revisiting recall and precision, and then continue exploring R-precision, AP, and MAP. We see how these can be measured manually and then using TREC supplied tools.

INLS490-154W: Information Retrieval Systems Design and Implementation

Evaluation-1

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.
