Information Architecture
Find Me
Data, Information, KnowledgeWe design for movement
From data
To information
To Knowledge
The Goal
• To go from fact
Estimated portion of all U.S. nuclear waste that Nevada's Yucca Mountain dumpsite will hold when it is full in 2046 :
3/5
The Goal
• To meaning
Estimated portion of all U.S. nuclear waste that Nevada's Yucca Mountain dumpsite will hold when it is full in 2046 :
3/5
Richter-scale magnitude of an earthquake last June twelve miles from the Yucca site :
4.4
Classification and Consequences
• A physician who doesn’t see a new cure• A poor student who can’t find financial
aid• A store where a product isn’t found
From fact to meaning
The right information at the right time in the right way
– Find information– Understand information– Use information
Special skills
• Information Architecture for Findability• Information Design for Understandability• Interaction Design for Usability
Information Architects specialize
• In Information Architecture– duh!
Unfortunate Seperation
Why the separation?

Information Architects
• What is IA?• IAI definition
1. The art and science of organizing and labeling web sites, intranets, online communities and software to support usability and findability.
2. The structural design of shared information environments.
3. An emerging community of practice focused on bringing principles of design and architecture to the digital landscape.
Findability
In the physical world
• Things that have fixed locations– We find with
maps and signs-- wayfinding
• Things that don’t– We find with
organization and wayfinding
In the digital world
• Nothing is fixed• Wayfinding and organization is the two
keys to findability• Role of IA is to shape the digital space to
enable findability.
Make things findable
• Organization– Build on Metadata– Browse systems– Search systems
• Wayfinding– Labels– Visual cues
Make things appear
• Serendipity systems– See also– Related– Popularity relationships– Also built on metadata
The structural design of an information space to facilitate task completion and intuitive access to content.
Definition
Information Architecture for the World-Wide Web Louis Rosenfeld & Peter Morville
Organizing info so
people can find stuff>
Who cares?
Once there were people with cowsAnd people without cowsThe people with no cows were hungry
They took to the roadAnd met at the marketAnd the people with no cows bought cowsThe people with cows had fewer cows, but money for other things
Now there are people with informationAnd people with no informationThe road is the computerAnd the market is the web
But the market is really bigAnd the people can’t find each otherSo we have ignorant peopleAnd people with no money
The cows are okay with this
Business is not.
The Goal
The players– Users, seeking information (cowless)– Businesses with information (with cows)– Intermediaries such as search engines and
directories, profiting on the exchange (marketplaces)
The goal is to get the users seeking the data to the businesses offering the data
Missing information
Lost sales -
Expensive support -
Duplicated effort -
Lost trust -
Lost lives?
Classification has Consequences
• A physician who doesn’t see a new cure• A poor student who can’t find financial aid• A store where a product isn’t found
IA has consequences
– Tagging with metadata– Organizing with CV’s– Creating navigation
systems – Optimizing search
Information Architecture manages information to make it findable
And IA can build brands.

Brian Collins’ Model of Brand
Brand and the User Experience
Hugh Dubberly’s Model of Brand
Creating a good customer experience is the essence of good branding
IA Realizes Brand
Product Quality = Brand LoyaltyI get asked a lot why Apple's customers are so loyal. It's not because they belong to the Church of Mac! That's ridiculous.It's because when you buy our products, and three months later you get stuck on something, you quickly figure out [how to get past it].
And you think, "Wow, someone over there at Apple actually thought of this!" And then three months later you try to do something you hadn't tried before, and it works, and you think "Hey, they thought of that, too." And
then six months later it happens again. There's almost no product in the world that you have that experience with, but you have it with a Mac.
And you have it with an iPod.

Football Fan?
51
Get to know your audience…
1. Who are they?
2. What do they care about?
Are the Patriots going to make the playoffs?
Show me photos!
What happened in the last game?
52
Get to know your audience…
1. Who are they?
2. What do they care about?
3. How do they think of the information and content?
Conference, division…
Schedules, standings…
53
Get to know your audience…
1. Observe others
2. Study Competitors and similar sites
3. Review your search logs
4. Do a card sort
54
Now what?
• Organize your information so it makes sense to your audience
• Structure your information to help users find it
• …using metadata
56
Metadata: what is it?
“metadata is data about data"
57
Metadata: what is it?
“Metadata tags are used to describe documents, pages, images, software, video and audio files, and other content objects for the purposes of improved navigation and retrieval”
‘Information Architecture for the World Wide Web’, 2nd ed., (2002) Rosenfeld, L. & Morville, P.
58
Types of Metadata
• Descriptive: the nature of the thing, what is it related to?…
• Intrinsic: composition of the thing, size, shape…
• Administrative: how can the thing be handled? Workflow…

Yahoo! Travel: Successful Meta Data
• Added Meta Data to page (descriptive meta tags, urls, titles in page)
• Was 2001: result # 300+ in Google/Yahoo Search
• 2002: result # 2• Users can find the content!
66
Not all Metadata is equal
• What are users interested in?• What do you want users to be able to find?• What metadata makes management
easy?
• Tag content for findability• Tag content for management
67
Exercise
• Listen• Write five descriptive words (or short
phrases) on your post-it• One word (or phrase) per post-it
• Don’t share– yet! Hold on!

The French Academy
• Founded in 1635• Multiple dialects• Goal: purify the French language• Goal: unify the nation (ensure that the
State and all citizens speak the same language)
73
The French Academy today
…but…
74
So what?
• How will you ensure they continue to do so?
• So what are your goals?
• How will you ensure that your users and your system speak the same language?

IA
And need help
80
Thus Controlled vocabularies (CV)Amy Warner defines a controlled vocabulary (CV)
as “organized lists of words and phrases, or notation systems, that are used to initially tag content, and then to find it through navigation or search.”
Of course, the IA can’t always be there…
82
I define them as
Documented relationships of words and concepts to assist people finding stuff.

• Acronyms: BBC, British Broadcasting Company; MPG, miles per gallon
• Variant spellings: cancelled, canceled; honor, honour
• Scientific terms versus popular use terms: acetylsalicylic acid, aspirin; lilioceris, lily beetle– From Synonym Rings and Authority Files
by Karl Fast, Fred Leise and Mike Steckel
Synonym rings include
87
• Sometimes on intranets, CV’s are skipped
• You think you can force people to use proper terms
• But people are lazy
I’m tired of typing “Controlled Vocabulary--- CV is shorter.
Why Bother?
88
• On the internet you want to be found
• You’ve got cows• But people can’t spell
“cows”• Plus users use short
queries– Average queries are 2.5
words– 30% of searches are one word queries

Exercise
Card sort
Take your keywords
Open your packets
Sort the items into similar piles.
Label the piles with post-its
Discuss
104
Building your own
1. Understand requirements
2. Harvest terms
3. Create groupings
4. Implement
5. Test
6. Maintain
105
What kind of CV do you need?
• What do you want your CV to accomplish? • To integrate with your navigation system? • To improve searching? To improve browsing?
Both? • How much vocabulary control do you want to
provide? Synonym ring? Facets? What level of vocabulary control is appropriate?
• What can your technology support?
106
Getting answers
• Content - specificity and stability• Technology - tools and integration. • Users – who are they• Maintenance- who will do it?
107
Content Inventory
• Link ID• ROT• Document type• Topics/
Keywords• Location
• Maintainer• Expiration• Access• Author• Existing/planned
Identify all content and attributes
108
Term harvesting
• Look Inward– Your site– Current keywords
• Look outward– Magazines– Competitors– Discussion lists
• Log harvesting– Search engines– Overture
• Ask people– Interviews– Card sorts– Free Listing
109
Sorting Terms
A Card Sort for Architects
• Multiple Groupings– Equivalent UF cheese=fromage– Broader terms BT cheese | dairy– Narrower terms NT cheese | cheddar– Related term RT cheese | crackers
110
Sleeping Bags BT Camping NT Down Sleeping Bags NT Synthetic Sleeping Bags NT Family Sleeping Bags NT Cold Weather Sleeping Bags NT 2-Season Sleeping Bags NT 3-Season Sleeping Bags NT Back Packing Sleeping Bags NT Expedition Class Sleeping Bags NT Ultralight Sleeping Bags RT Backpacks RT Ultralight Backpacking RT Sleeping Bag Liners RT Sleeping Pads RT Stuff Sacks RT Pillows
From Creating a Controlled Vocabularyby Karl Fast, Fred Leise and Mike Steckelhttp://www.boxesandarrows.com/archives/creating_a_controlled_vocabulary.php
111
Sorting conflicts
• Cheese goes in dairy or in sandwich materials?
• A cheese basket?• String cheese?
Choices fit strategy
112
Associations
• What is related• What is required?• What else is interesting?
Relevancy is king
113
Possible Relationships
• Process/agent (camp fires/matches)
• Action/product of action (baking/cakes) • Agent/counteragent
(allergies/antihistamine) • Raw material/product (wool/sweater).
114
Implement
• Implementation dependant on situation and tools.
• May be slow painful data entry– know this and prepare.
115
Test
• Test with users – did you get it right?
– Browse Testing– Search Testing– Monitor quantitative
– Refine, refine, refine
116
Maintain
• Who maintains it?• What the rules for new terms?• Document your decisions.
117
Is that all?
NO!
Life beyond enumerative classification….
118
Faceted Classification
was developed, prior to the existence of computers, by S. R. Ranganathan, a Hindu mathematician working as a librarian.
119
S. R. Ranganathan1892-1972
My dream:•to systematically describe, in detail,
the contents of complex documents discussing compound subjects, and to
• codify those descriptions into a sequenced numerical form that would
• make it possible to retrieve exactly what was needed from wherever it was located in the library
• in order to save the time of the reader.
120
And ... describe the entire universe of ideas using classification and notation.
121
S. R. Ranganathan1892-1972
The Five Laws of Library Science
1. Books are for use. 2. Every reader his or her book. 3. Every book its reader. 4. Save the time of the reader. 5. The Library is a growing organism.
122
Colon Classification System
Describing life, the universe, & everything, it used facets to classify. It affected the world of
• classification,• categorization, • information retrieval &• information architecture.
123
Ranganathan’s 5 Facets
• who: personality• what: matter• how: energy• where: space• when: time
Sound familiar?
124
Ranganathan’s 5 FacetsImagine a book about “the design of wooden furniture in 18th century America.”
Personality—furniture Matter—wood Energy—design Space—America Time—18th century
125
Essential Qualities of a Facet
• Mutually exclusive; represents a characteristic of division not found in any other facet
• Cannot be further sub-divided• Relationships between facets are non-
hierarchical (though within facets…)
126
The broad categories into which the subject area is divided. A facet consists “... of a group of terms that represents one, and only one, characteristic of division of a subject field....no two facets may contain terms that could represent the same concepts.” —Louise Spiteri
Facets
127
Heady stuff?
What does all this philosophical mumbo jumbo mean?
128
Heady stuff?
Yahoo! Shopping uses facets to help users select a camera
129
Ordinary stuff?
Epicurious uses facets to help users find recipes
130
Yahoo! Personals
• Faceted classification by Yahoo! Personas
• Content by the users
131
What’s the difference?
Electronics
Camera
Digital
Film
PDAs
Televisions
Camera facets
Pixels
Zoom
Price
132
Our Music example
Enumerative
• Modern– Rock
• Alternative– Seattle– Atlanta
Faceted
• Mood• Tempo• Artist• Use
133
Mix and match?
In Yahoo Shopping
• Electronics > Cameras > Digital
• Then choose by pixel, zoom and price
• Then offer camera bag, flash card, batteries?
134
Facets, anyone?
What facets would you use to describe the qualities of a song?
135
Making Facets
1. Consider the universe of documents to be indexed.
2. Consider user finding strategies.
3. Analyze each document to identify the facets.
4. Group isolates (simple-concept subjects) into the facets.
5. Apply the notational system.
(I skipped some steps, to avoid wonking out….)
136
Are Facets Hard?
Consider:– Facets for a knife store?– Facets for a kitchen store?– Facets for a book store?
137
Before jumping in…
Consider:• How various is your content?• How complex is your subject?• How do people find your content?• How much time do you have?
Is this all there is?
Information Architecture is:
Architecture in Information Spaces.
Dan Klyn (and TUG) is bringing Richard Saul Wurman’s and other architect’s views back to make better digital products
http://understandinggroup.com/
“Less is more.” ~ Mies
What does a digital product want?
• A librarian?• An urban planner?• An architect?
“Modern Systems! Yes indeed! To approach everything in a strictly methodical manner and not to waver a hair’s breath from preconceived patterns, until genius has been strangled to death and joie de vivre stifled by the system– that is the sign of our time.” Camillo Sitte
Homework
• Content inventory: what’s in your site?• Organizational Scheme
– Hierarchal?– Faceted?– Combination?
• Portfolio: Site map (a la Dan Brown’s Communicating design Chapter 5)
