Information Retrieval

NUS SoC, 2015/2016, Semester II Video Conferencing Room (COM1 02 VCRm) / Fridays 11:00-13:00

Last updated: Thursday, December 14, 2017 - This iteration of the class has finished. Please refer to the current iteration of the class for detail and note that the lecturer has changed.

Module Description, Aims and Objectives:

Module Description, Aims and Objectives: This module discusses the basic concepts and methods of information retrieval including capturing, representing, storing, organizing, and retrieving unstructured or loosely structured information. The most well-known aspect of information retrieval is document retrieval: the process of indexing and retrieving text documents. However, the field of information retrieval includes almost any type of unstructured or semi-structured data, including newswire stories, transcribed speech, email, blogs, images, or video. Therefore, information retrieval is a critical aspect of Web search engines. This module also serves as the foundation for subsequent modules on the understanding, processing and retrieval of particular web media.

Starting this semester, I will also be maintaining a Facebook page (accessible from the FB link on the top menu) for this course across cohorts. Current students and alumni are welcome to contribute news and items of potential interest to the page (i.e., IR news, job openings specific to IR).

N.B. We will be teaching and using the Python programming language throughout this class.
Updated We will using Python 2.7.x or Python 3.4.x, as these versions also work for the NLTK library.
