- What do you want your CV to accomplish?
- Do you want the CV to integrate with your navigation system?
- Are you planning on using the CV to improve searching? To improve browsing? Both?
- Are you planning to show term relationships in your search results?
- How much vocabulary control do you want to provide? Synonym ring? Facets? What level of vocabulary control is appropriate?
-
Specificity
-
Stability
-
What will be your method for keeping up with changing terminology?
-
Who is the target audience for the site?
-
identify the terms that will bring the most success to your user population, enabling them to find exactly the information they need
-
review competitors’ sites, journals or magazines on your subject matter, or discussions by subject experts on the web
-
display search results (as in 8 hits, 0 hits, etc.), you can see how successful people are. Or, reproduce the searches yourself to determine if people are getting relevant hits
-
Is there a way to ask users what they look for on your site? How would they describe your site’s contents?
-
For each term, ask what is the broader (more general) term? What are the narrower (more specific) terms? If you are using terms to establish a navigation system, is this a preferred term or a variant? Your controlled vocabulary will start to come together as context is added to each term.
-
a good CV design process is essentially a user-centered process
-
Identify the “see also” terms. What else might be interesting to your target audience?
-
Try to strike the right balance between suggesting options and overwhelming a user with choices.
-
Establish a record of the rules you are using if you are creating a large thesaurus.
-
Remember all those decisions about what term goes where? Review the decisions you made and record what the decision was and why you made it. This will enable you to maintain consistency as your CV changes and expands.
-
When do you include a new term? What constitutes a relationship or RT? When do you delete terms? What is the basis for choosing a preferred term? When are terms singular or plural? Nouns or verbs? How will you deal with punctuation?
-
using your controlled vocabulary for searching, get ready for more work: Tweaking the algorithms for a search engine is a difficult job involving lots of tradeoffs.
-
Start with yourself. Use the site to find various types of information based on assumptions you made earlier. Can you identify which content goes in which slot pretty easily? Can you search and get the results you expect? If using your CV to improve searching, enter a term and carefully look at the first page of returns. Are these the results you want your users to get for this search term?
-
However, maintenance is required to keep your CV viable and usable. Constant monitoring, evaluation, and tweaking are critical.

Allard Strijker"You have probably heard IAs discussing the benefits of their latest taxonomy project and how you should be implementing one. But how, you might wonder, can you get started? This article describes a process for building your own controlled vocabulary (CV). A
previous article discussed the concept of a CV—the “what.” This article focuses on the “how.” In this article we are looking at a process for creating any kind of controlled vocabulary. While our ultimate goal in this series is to explain facets, the details of facet analysis will be described in a future article. At this point, we are still exploring fundamental concepts and techniques."vocabulaire classification metadata controlled vocabulary Development
