Structured Data: None / Some / All

Mad*Pow User Experience, May 2012

1995-2012 = Gazillions of Websites

Our design problem was an evolution of visual literacy

— Readers were trained to find information in printed books/magazines/newspapers

— Digital publications lack physical context

— Location and scope of information was invisible

Mad*Pow | May 2012 | 2

Clients = Publishers Users = Readers

Our Design Task was to connect Readers to content

— Adapt graphic language – type, color, image – from the page to the screen

— Create navigation systems that help users understand what they can find on a website

— Communicate the structure of content in flexible repeatable units


2012=Massive Pattern of Nodes

2012=Nodes with Geo Context

Today Users are

— Convinced they can find what they want “on the Internet”

— Producing & managing dematerialized content: photos, videos, music, email, compound documents

— Creators & consumers with storage/creation and retrieval/consumption needs

— Looking for something all the time


Today Users want to

— Record, share, publish

— Be convinced, amused, in control

— Find, sort, sift and copy

— Mix, reorder and arrange

They don’t explicitly know what metadata is

They are solving problems by implicitly manipulating metadata


Today’s IA/UX Problem

Every IA/UX problem is a Metadata Continuum

— No Structure Vacuum Raw

— Some Structure Marsh Eatable

— Complete Structure Field Cooked


Unstructured Data

Data Vacuum: no metadata has been added to items

Even Data Vacuums include content & context

The 50-year-old Information Retrieval / Library Science trade-off:

— Precision: finding only what you are looking for

— Recall: not missing anything that might contain what you are looking for


Data with no structure: Names

— A character-string a person, place or thing is known by

— People have many names: professional names, familiar

names, legal names

— Places and things have many names in different

languages

— As data, a name presents a major problem:

IT IS NOT UNIQUE

— For example: “paul kahn”

Use algorithms to surface what users might want

to see (and what we want them to see)

Where did I put that document?

The tools we use:

— Personal Memory

— Folder names

— Desktop search

What kinds of structure can we present?

Mad*Pow | May 2012 | 15

Implicit metadata:

— Document type

— File name

— Document content

INFORMATION ANXIETY 2

Semi-Structured Data

Data Marsh: some metadata without predefined language or requirements

— Tagging : users add uncontrolled keywords

— Profile: users intentionally add metadata about themselves

— Time / Location stamps: where and when

— Tracking: users unintentionally add metadata about themselves as interactions are tracked

Aggregation/Reproduction Sites

— Sites that aggregate user-provided content Slideshare / YouTube / Dailymotion / Vimeo / SoundCloud / Flickr

— Sites where users create and republish content to social networks LinkedIn / Facebook / Twitter

— Feature

— Categories + Time

— Common Focus

Implicit metadata:

— Time/Date stamp

— Document type

Structured Data

Data Fields: where metadata has been explicitly added

to items according to an agreed-upon standard

— The Content is made to fit a pre-defined structure

— The required parts of the structure are completed

— Each metadata dimension qualifies and reinforces the

meaning of the content

— Many kinds of relationships can be harvested

Would the world be a better place if

— Everything had a unique ID?

— Every digital object with a unique ID contained

structured data?

How does structured data affects quality of life questions?

A Proverb for User Centered Design

— Hwa is thet mei thet hors wettrien

the him self nule drinken

— Who can give water to the horse

that will not drink of its own accord?

Structured Data Value Proposition

— People want to find things, they don’t want to “learn” how to find things

— People understand how to use Structured Data

— No one wants to create Structured Data

— It is our task to leverage the Structured Data people already understand
