Information Architecture (IA) is a practice of making sense

Critical Components Of IA* Ontology: Do you know what you mean when you say what you say? Ontology Taxonomy Choreography Taxonomy: Have you provided logical structures that bring meaning to what you present? Choreography: How is meaning affected across various channels, over time and through usage? *HT  @DanKlyn

Ontology This is a fish. 6

Meaning is subjective Meaning is socio political Meaning is psychographic Meaning gets lost in translation Meaning is not talked about enough 7

...meaning gets further complicated at the intersection of humans & technology. 8

Good user experience is built on a foundation of shared meaning 9

Taxonomy is Rhetoric The way you choose to organize your vegetables says something about what kind of store you are 14

“It takes knowledge to know that a tomato is a fruit, and wisdom not to put it in a fruit salad.” – Miles Kington 15

Mental Models Matter A mental model is an explanation for the way someone makes sense of something. These models of perception shape our behavior and how we relate to information that we encounter. 16

Lesson #2 Avoid Poly-hierarchical overload 17

The more tomato-like objects, the less effective the taxonomy More Usefulness of Taxonomy Less “If everything is a vegetable, nothing is a vegetable.” Instances of Polyhierarchy More 18

Lesson #3 Cultural meaning matters 19

Which is a wedding? Which is a funeral? 20

Controlled Vocabularies • A controlled vocabulary is a list of approved terms and definitions for a particular context and/or setting • Frameworks like this can help teams to decide on things like: • Variant Spellings (i.e. American vs. British) • Scientific vs. Popular Term Use (i.e. Cockroaches vs. Periplaneta Americana) • Acceptable Synonyms (i.e. Automobile vs. Car) • Acceptable Acronyms (i.e. GE vs. General Electric) • Business vs. User Terms (i.e. What we say in meetings vs. what we say to customers) • Identification of homographs (i.e. the word “pool” can relate to “swimming pool” or “shooting”) 44
