This course will cover the theory, design and implementation of text-based information retrieval systems, including algorithms and techniques at the core of modern search systems. Specifically, we will learn the key concepts and models relevant to information retrieval and storage, including efficient text indexing, boolean and probabilistic retrieval models, retrieval evaluation, relevance feedback, document classification, learning to rank, document clustering and link analysis. We will implement key retrieval models on top of an open-source search engine system. Prerequisites: students should have had some exposure to basic probability, statistics, data structures and algorithms. You should be able to learn new software libraries on your own and design and develop functions on top.
Course GoalThrough this course, students will gain solid theoretical knowledge and enough practical experience to develop and diagnose their own search systems in the future.

Attendance and Make-up Policies
Every student should attend the class, unless you have an accepted excuse. Please check student rule 7 http://student-rules.tamu.edu/rule07 for details.
Homework Late Policies
For the programming/written homework assignments, you have a total of 5 late days that you can use during the semester. However, a single assignment can be submitted up to 2 days late only. For the purposes of the class, a late day is an indivisible 24-hour unit. Once you exhaust your 5 late days, we will not accept any late submissions.
Students should have taken the course Data Structure and Algorithms (CSCE 221).
Textbook and Material
The primary textbook: Introduction to Information Retrieval, Christopher D. Manning, Prabhakar Raghavan, and Hinrich Schutze, Cambridge University Press. 2008. Relevant tutorials and papers will also be handed out during the class.

Upon accepting admission to Texas A&M University, a student immediately assumes a commitment to uphold the Honor Code, to accept responsibility for learning, and to follow the philosophy and rules of the Honor System. Students will be required to state their commitment on examinations, research papers, and other academic work. Ignorance of the rules does not exclude any member of the TAMU community from the requirements or the processes of the Honor System.
