pattern recognition for technical communicators
DESCRIPTION
Pattern recognition is an essential mental strategy for acquiring and disseminating knowledge, though we are usually not aware that we do it. By understanding what pattern recognition is and how it works, technical communicators can employ it to efficiently acquire information, structure deliverables and help their users to use effective documentation efficiently.TRANSCRIPT

WHAT IS PATTERN RECOGNITION?
Part of human perception:
1. Receive sensation and organize it.
2. Recognize patterns.
3. Formalize patterns as rules to interpret and decide.

HOW ABOUT AN EXAMPLE?
Aardvark, J.R. (1980). Ants, and how to eat them. Journal of Orycteropodidae Studies, 80, 11-17.
Barker, R. (1982). Rum babas, and what to do if you’ve got them. Reading: Goodnight From Him. …
Rule set
1. Last name, initial(s). (Year of publication).
2. If it’s an article: Title, journal title, volume, pages.
3. If it’s a book: Title. City: Publisher.
We learn patterns by examples – or by rules.

WHY SHOULD TECH COMMUNICATORS CARE?
We do it anyway…
1. When we gather information Reading specs and designs Interviewing subject-matter experts
2. When we create and order information Write topics Structure topics into deliverables

WHY SHOULD TECH COMMUNICATORS CARE?
We do it anyway, so we might as well do it smartly!
If we make sense of our subject more efficiently…
If we structure better what we need to convey…
… we can provide better documentation!

HOW DOES PATTERN RECOGNITION WORK?
Bottom-up processing
1. Experience and organize
2. Match similarities
3. Segment into groups
… building up a representation from elements.
![Page 20: Pattern recognition for technical communicators](https://reader033.vdocuments.net/reader033/viewer/2022060108/554dc79eb4c905c7488b51c2/html5/thumbnails/20.jpg)
HOW DOES PATTERN RECOGNITION WORK?
What is this? How do you know?
![Page 21: Pattern recognition for technical communicators](https://reader033.vdocuments.net/reader033/viewer/2022060108/554dc79eb4c905c7488b51c2/html5/thumbnails/21.jpg)
HOW DOES PATTERN RECOGNITION WORK?
Top-down processing
1. Know general concept and rules
2. Contextualize them
3. Apply them
… searching for confirmation by “template matching”.
![Page 22: Pattern recognition for technical communicators](https://reader033.vdocuments.net/reader033/viewer/2022060108/554dc79eb4c905c7488b51c2/html5/thumbnails/22.jpg)
HOW DOES PATTERN RECOGNITION WORK?
Top-down
Uses prior knowledge
Concepts elements
Emphasizes context
Quick, but sometimes wrong
Bottom-up
No prior knowledge
Elements concepts
Emphasizes relations
Slow, but usually correct

PATTERN RECOGNITION IN TECH COMM
To overcome writer’s block and start writing
Incomplete, inconsistent information?
Start bottom-up with similar items as “seeds”.

PATTERN RECOGNITION IN TECH COMM
To help your readers navigate and understand.
Segment and structure topics.
Phrase headings in a consistent, recognizable way.
Table of contents is top-down.
Search and index are bottom-up, template matching aids.
![Page 34: Pattern recognition for technical communicators](https://reader033.vdocuments.net/reader033/viewer/2022060108/554dc79eb4c905c7488b51c2/html5/thumbnails/34.jpg)
FINAL WORDS OF ADVICE AND WARNING
Patternicity: Humans are addicted to meaning.
Some patterns refuse to be recognized
Pattern recognition occurs in contexts
Creating tech comm is often a top-down process … ... but using it is often bottom-up searching!
