Basic concepts such as retrieval evaluation, query languages, query operations, indexing and searching are introduced. Some advanced topics including parallel and distributed IR, and multimedia IR are discussed.
Upon successful completion of this course, students should be able to：
Upon successful completion of this course, students should be able to：
1. describe the basic concepts and models in information retrieval;
2. apply basic techniques in user relevance feedback, indexing and searching;
