INFORMATION RETRIEVAL CONCEPTS AND PRACTICES

PREREQUISITES:

MLIS and Dual MAS/MLIS: completion of the MLIS core

MAS: completion of MAS core and permission of the SLAIS Graduate Adviser. Basic knowledge of web design highly recommended.

GOAL: The primary focus of this course is on the techniques and strategies required to effectively and efficiently use online retrieval systems; it builds on the skills and techniques covered in the MLIS Core. Current research in online retrieval is also covered. Although an ability to conduct searches in one or more systems, such as Proquest or search engines such as Google, is an expected outcome of the course, it is not a major objective. Instead, the focus is on more conceptual issues, such as database structure, language issues, search strategies, and evaluation of results. Specific online systems serve as illustrations. The course is designed to provide students with a strong base to learn other systems, especially given today’s ever-changing information environment, in addition to knowledge of specific systems.

OBJECTIVES:

Upon completion of this course students will be able to:

  • Understand the research basis for selected information retrieval concepts, theories and models [1.1, 1.2, 1.3, 1.4, 2.1, 2.2, 4.1]*
  • Analyze and discuss current issues and research in information retrieval [1.3, 4.1]*
  • Understand and appreciate the capabilities and limitations of information retrieval systems and models [1.3, 2.1]*
  • Demonstrate appropriate search strategies and vocabularies for information retrieval [1.1, 1.3, 1.4]*
  • Demonstrate problem solving skills to handle a complex search problems [1.1, 1.3, 1.4]*
  • Identify and discuss problems, issues, and future developments in information retrieval 1.3, 1.4, 2.1, 2,2, 3.1, 4.1, 5.1]*

* Course objectives are stated in terms of student learning outcomes and reference the iSchool Statement on Graduate Competencies.
