Course Times and Location
- Location: online
- Email should be the primary means of out-of-class communication; however
I can meet with students in person by appointment.
- Course Overview
- This course covers the storage and retrieval of unstructured digital
information. Topics include automatic index construction,
retrieval models, textual representations, efficiency issues,
search engines, text classification, and multilingual retrieval.
- Grading Policy
- Work for the class includes homework assignments, an independent research project, exams, and scholarly engagement.
Refer to the course outline and syllabus for details. I assign grades with plus/minus modifiers (e.g., A+, B-, etc...)
