Ontology: Do you know what you mean when you say what you say?

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?

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

Mental ModelsMatter

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.

One word, many meanings

Lexicography vs Ontology

• Lexicography is the practice of compiling dictionaries. Lexicographers collect different meanings for words• Ontology represents the knowledge of terms

and concepts within a domain

26

Page 32: Lessons from an Ontology Nerd

Reading Level Matters

27

• Words per sentence• Average grade level of words• Characters per word• Use of organizational devices

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”)
