Course website: http://courses.fims.uwo.ca/rubin/9202/ (accessible to enrolled students)
Location: FIMS & Nursing Building, Room 4130
Time: Mondays, 9:00- 11:50 a.m.

Theory and practice in indexing and in constructing subject retrieval languages in thesaurus form. Distinguishing between controlled and natural language indexing, and between subject headings and index terms. Applying facet analysis to thesaurus construction. Selected topics in the theory of subject analysis. A new significant component of the course will overview current metadata and linked data initiatives and discuss how various metadata standards support subject access.

Students will complete three (3) reports and present in the practical workshop. The main class Project will have 5 sub-components that need to be accomplished and submitted in the course of 5-6 weeks.
- Report 1 (Analysis of ERIC indexing terms) - 15 %
- Mini-Thesaurus Construction Project - 50 % (total, with 5 sub-parts)
See sub-component below:
Part 2.1. Collection of complex subject descriptions & indexable terms (5%)
Part 2.2. Categorization of subject area by facets (10%)
Part 2.3. Demonstration of hierarchies and broad/narrow term relations in subject area (15%)
Part 2.4. Demonstration of associative relations and 2 types of thesaural displays (10%)
Part 2.5. Written analytical Report (2) (10%) and presentation in the class workshop
Report 3 (Metadata analysis & Reflection) - 25%
Participation - 10 %
The course is under considerable review as the new digital environments require new methods to be reviewed and taught. The original formal course objectives were (excluding the more innovative material in parts II and III):
- To teach students how to analyse the subject of a document, and to translate that expression into a suitable set of index terms.
- To expand students’ knowledge of the structure and use of indexing, the principles of thesaurus construction and theoretical topics in subject analysis.
- To provide students with an opportunity to practice indexing and thesaurus construction skills.

<Comments> This XML code is shared with the class as a simple example of how you could start building up an XML file containing your thesaurus bibliographic metadata (the description of who created it, when, for what purpose, audience, etc.) as well as your thesaurus main facets (or, top terms (TT), BT, NT, USE, UF relations and scope notes (SN). </Comments>
<Purpose> The purpose of this thesaurus is to act as a structured vocabulary... </Purpose>
<Audience> The target audience for this thesaurus is undergraduate students... </Audience>
<Agents> This facet contains concepts that may carry out an operation... </Agents>
<Space> This facet contains terms that refer to physical locations and places. </Space>
<!--Do you think YOU create a similar block of XML-encoded metadata for your own thesaurus based on this example? Feel free to start by copy-and-pasting the lines between bars into an editor (like the DreamWeaver, Notepad++, or FrontPage). You can delete any content between the tags, add new tags and content, or replace what's irrelevant with the right content for your project..-->
