Designing Structure

Information Architecture

A SHORT HISTORY OF ARCHITECTURE

Cave

Hut

Stone Age City

VITRUVIUS

firmitas, utilitas, venustas : : durability, convenience, beauty 

Durability

“Durability will be assured when foundations are carried down to the solid ground and materials wisely and liberally selected” Vitruvius

The hotel had several design features that made up for its foundation:The reflecting pool (visible in the picture above) also provided a source of water for fire-fighting, saving the building from the post-earthquake firestorm;[1]

Cantilevered floors and balconies provided extra support for the floors;A copper roof, which cannot fall on people below the way a tile roof can;Seismic separation joints, located about every 20 m along the building;Tapered walls, thicker on lower floors, increasing their strength;Suspended piping and wiring, instead of being encased in concrete, as well as smooth curves, making them more resistant to fracture.[2]

Technical Earthquakes

I’m searching for “my architect, not

“movies, directors, actors”

Social Earthquakes

If people post jobs in discussion areas, any user can

move them to job board

If people use connection invites to spam/market, they

can be reported.

Convenience

“When the arrangement of the apartments is faultless and presents no hindrance to use, and when each class of building is assigned to its suitable and appropriate exposure” Vitruvius

Sound familiar? We’re talking

usability!

Rackspace headquarters in in a former mall. The building is so usable for moving people around, it's easily repurposed. Robert Venturi calls this a “decorated shed”

Malls online epitomize convenience, and are typically extremely usable. Anthropologie is elegant and functional.This simple model could be repurposed for any side dealing with objects and metadata

Bilbao did not leak. I was so

proud.

The MIT project, they were interviewing me for MIT and they sent their facilities people to Bilbao. I met them in Bilbao. They came for three days.W: This is the computer building.G: They were there for three days and it rained every day. And they kept walking around. I noticed they were looking under things and looking for things, and they wanted to know where the buckets were hidden, people putting buckets out. I was clean. There wasn't a bloody leak in the place. It was just fantastic. But you've got to -- yeah, well, up until then, every building leaked.W: Frank had a sort of -- sort of had a fame -- his -- his fame was built on that in L.A. for a while. You know, Frank, you've all heard the Frank Lloyd Wright story when the guy -- the woman called and said, "Mr. Wright, my -- I'm sitting in the couch and the water's pouring in on my head," and he said, "Madame, move your chair."G: So, some years later I was doing a little house on the beach for Norton Simon, and his secretary was kind of a hell-on-wheels type lady -- called me and said, Mr. Simon's sitting at his desk, and the water's coming in on his head, and I told him the Frank Lloyd Wright story.W: Didn't get a laugh.G: No. Not now either. http://www.ted.com/talks/frank_gehry_asks_then_what.html

I call it the "Then What?" Okay, you solved all the problems, you did all the stuff, you made nice, you loved your clients, you loved the materials, you loved the city, you're a good guy, you're a good person... and then what? What do you bring to it?

See his great TED talk http://www.ted.com/talks/frank_gehry_asks_then_what.html

“Early in life I had to choose between honest arrogance and hypocritical humility. I chose honest arrogance and have seen no occasion to change.” Frank Lloyd Wright

Beauty (delight)

“when the appearance of the work is pleasing and in good taste, and when its members are in due proportion according to correct principles of symmetry.” Vitrvius

“Less is more.” ~ Mies

SEAGRAM BUILDING (Philip Johnson did interiors, 1957)

This logical and elegant 38-story skyscraper (525' H) has alternating horizontal bands of bronze plating and bronze-tinted glass and decorative bronze I-beams which emphasize its verticality. Placed to the rear of its site and set back from Park Avenue, it incorporates a large plaza in the front as part of the design--thus avoiding the need for set-backs. It uses granite pillars at the base and has a two-story glass-enclosed lobby.

Is this Beautiful?

“Less is a bore.” ~ Venturi

Is this Beautiful?

Do we dictate what is beautiful by constraining

user choice?

Or support passionate use that may not meet our

aesthetic standards?

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.

1. Observe others

2. Study Competitors and similar sites

3. Review your search logs

4. Do a card sort

75

Now what?

• Organize your information so it makes sense to your audience

• Structure your information to help users find it

• …using metadata

METADATA

Pictures of you

81

Metadata: what is it?

“metadata is data about data"

82

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.

Descriptive

• Ham• Cheese• Honey• Olivia’s

Intrinsic

What does the camera know? What does the system know?

Administrative

86

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

87

Exercise

• BALL• Write as many descriptive words (or short

phrases) on your post-it• One word (or phrase) per post-it

• Don’t share– yet! Hold on!

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?

And need help

101

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…

102

I define them as

Documented relationships of words and concepts to assist people finding stuff.

• 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?

108

• On the internet you want to be found

• Plus users use short queries– Average queries are 2.5

words– 30% of searches are one word queries

• On large scale sites, there is enough data to do this programmatically, but on small sites, not.

I want a cannon camera.

Is that all?

NO!

Life beyond enumerative classification….

134

Faceted Classification

was developed, prior to the existence of computers, by S. R. Ranganathan, a Hindu mathematician working as a librarian.

135

Ranganathan’s 5 Facets

• who: personality• what: matter• how: energy• where: space• when: time

136

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…)

138

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

143

FACETS, ANYONE?Create ball facets

144

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….)
