How to Validate a Taxonomy

  • Taxonomy is the key to being able to supply the appropriate content in dynamic user interfacesand supporting information services such as personalization (e.g., portals), syndication (e.g., RSS feeds), and harvesting (e.g., search). Taxonomy development and validation is on the application development critical path. Effective methods to provide confidence that the taxonomy is good enough to develop against is very important.

    Benefits

    The goal of taxonomy testing is to confirm that a taxonomy will work for tagging content, publishing content, and finding and using content in user-facing applications. This workshop will discuss taxonomy validation methods, present case studies that go beyond typical card sorting, and conduct hands-on activities for participants.

    The validation methods include:

    • Working with most popular queries
    • Delphi card sorting
    • Task-based usability
