Course Description: |
This lecture-oriented course studies the theory, design, and implementation of
text-based search engines. The core components include statistical
characteristics of text, representation of information needs and
documents, several important retrieval models, and experimental
evaluation. The course also covers common elements of commercial
search engines, for example, integration of diverse search engines
into a single search service (federated search, vertical
search), personalized search results, and diverse search results.
The software architecture components include design and
implementation of large-scale, distributed search engines.
This is a full-semester course. The graduate sections (11-642 and 11-742) are worth 12 units. The undergraduate section (11-442) is worth 9 units. The main difference between the three sections (11-442, 11-642, 11-742) is the amount of analysis, writing, and time required to complete homework assignments. |

Advice From The Faculty: |
This course is a lot of work.
Take care of yourself. Do your best to maintain a healthy lifestyle this semester by eating well, exercising, avoiding drugs and alcohol, getting enough sleep and taking some time to relax. This will help you achieve your goals and cope with stress.
If you find yourself struggling with the material or workload, please ask for help. All of us benefit from support during times of struggle. You are not alone. There are many helpful resources available on campus and an important part of the college experience is learning how to ask for help. Asking for support sooner rather than later is often helpful. If you or anyone you know experiences any academic stress, difficult life events, or feelings like anxiety or depression, we strongly encourage you to seek support. Counseling and Psychological Services (CaPS) is here to help: call 412-268-2922 and visit their website at https://www.cmu.edu/counseling/. Consider reaching out to a friend, faculty or family member you trust for help getting connected to the support that can help. |
