The Information Architecture Institute defines information architecture as
“the art and science of organizing andlabeling websites, intranets, online communities and software to support usability.”
Information Architecture work consists of:
- Defining website goals and target audiences.
- Identify content and functional requirements.
- Grouping and categorizing content
- Labeling content
- Designing navigation systems
Grouping and categorizing content
- Exact organizational schemes: alphabetical, chronological, geographical
- Ambiguous organizational schemes: topic, task, audience, metaphor, hybrid
- Ambiguity: we use language used to classify and label content, and language is often ambiguous.
- Heterogeneity: a website consists of content of different types and forms.
- Difference in perspective: Labeling and classifying are affected by personal perspectives
- Internal politics
