Information Architecture Designing and Organising Digital Information SpacesPart II. IA Building Blocks
organization structures
Organization Structures
  • Hierarchy: taxonomies, top levels, mental model
  • Database:structured content, metadata, facets, relationships
  • Hypertext:cross-references, contextual

hierarchy

hypertext

database

organization schemes
Organization Schemes
  • Exact
  • Everything has a place.
  • Easy to create and maintain.
  • Great for known-item searches.
  • e.g., white pages, geography, chronology
  • Ambiguous
  • Fuzzy and full of overlap.
  • Hard to create and maintain.
  • Great for subject searches, associative learning.
  • e.g., yellow pages, topic, audience

  • “Consider for example the proceedings we call games. I mean board games, card games, ball games, Olympic games, and so on. What is common to them all?”

Most categorization is automatic and unconscious.

olive blocks

small spheres

orange circles

glass marbles

big mountains

When we define categories, we choose which attributes or properties to surface.

hollow shapes

“Categorization is not a matter to be taken lightly. There is nothing more basic than categorization to our thought, perception, action, and speech.”

George Lakoff

Professor, Cognitive Linguistics

UC Berkeley

slide12

Prototype Theory

  • Prototype-based categories defined by fuzzy cognitive models rather than objective rules.
  • Family Resemblances
  • Members may be related without all members sharing any common property.
  • Centrality
  • Some members may be better examples
  • Membership Gradience
  • Some categories have degrees of membership and no clear boundaries
  • Basic Level Primacy
  • A psychologically basic (folk-generic) level in the hierarchy. Optimal for learning, recognition, memory, knowledge organization.

Descriptive Name
  • A name which describes a product, service, or company. Descriptive names, such as Workgroup Server and Pacific Gas and Electric, have content, but often are not protectable and typically are not favored by trademark attorneys.
  • Proprietary NameA protectable name which one is able to own and trademark, as opposed to a descriptive name, which is not protectable or ownable. See Brand Name.
  • Suggestive NameA name built on or utilizing words or word parts which suggest or refer to the goods or services, but do not literally describe them. Oracle and Safeway are suggestive. Suggestive names are often protectable (unlike descriptive names), but may be weaker as trademarks than coined/fanciful or arbitrary names.
  • PsycholinguisticsThe study of how language is understood and interpreted and how and why the individual responds to discrete aspects of language.

Navigation
  • Support task flow
  • Provide context and flexibility
  • Avoid drowning content

supplemental navigation
Supplemental Navigation
  • Sitemaps
    • Table of contents
    • Top few levels of hierarchy
    • Scope / organization
    • Exploratory browsing
  • Indexes
    • A-Z index (back-of-book)
    • Finely grained
    • Relatively non-hierarchical
    • Known-item finding
search
Search
  • “…studies show that search is still the primary usability problem in web site design.”
  • Vividence Research: Common Usability Problems
  • Poorly organized search results
  • Poor information architecture
  • Source: Flexible Search and Navigation using Faceted Metadata (UC Berkeley SIMS)

“Most of the complaints we get are due to the way users search; they use the wrong keywords.”
  • Manufacturing Manager in Must Search Stink? by Forrester Research
slide37
“I really do see the future in terms of categories and clicking. The more I watch what\'s happening with the evolution of web sites, the more I believe that Search is essentially an experiment that has failed.”
