Information Retrieval
NUS SoC, AY 2022/23, Semester II, Fridays 12:00-14:00
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.
There is 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 using the Python 3 and the NLTK library throughout this class.
Course Characteristics:
- Modular credits: 4.
- Prerequisites: (CS2010 or its equivalent) or CS2020 or (CS2040 or its equivalent). Important: It is highly suggested to have some advanced mathematics background such as probability and statistics, and/or linear algebra. Exceptions to these pre-requisites can be made on a case-by-case basis only. See instructor for details.
