Graduate students will be able to:

1. Explain KOS functions and structure and apply this knowledge
2. Find knowledge organization systems (KOS) that are candidates for a given application
3. Access and acquire KOS, especially through the Web
4. Analyze the structure of a KOS and evaluate its suitability for a given application
5. Develop / modify / maintain KOS
6. Assign subject indexing terms to a wide variety of resources (such as journal articles, books, images, websites, organizations, people)
7. Write indicative and informative abstracts and other summaries
8. Contribute to discussions on automatic subject metadata assignment, semantic enrichment, and automatic summarization
9. Contribute to discussions on the use of KOS in information retrieval systems, both behind-the-scenes component and user interface

KOS functions and KOS structure: Facets, hierarchy, concept combination, inference on concept relationships (optional for advanced students: description logic)
