Tags & Tagging
Tags• User-added descriptive metadata
Tagging• The practice of
– users adding descriptive metadata to resources– allowing users to add and share their own
descriptive metadata

Collaborative Categorization
• Tags are shared• Feedback loop
![Page 16: Access 2005 Tagging](https://reader033.vdocuments.us/reader033/viewer/2022061219/5483e162b4af9f1b5b8b4668/html5/thumbnails/16.jpg)
Simple Tags
• Flat namespace• No hierarchy• Simple interface (text box)• WordsSmashedTogether

“Folksonomies … don't support searching and other types of browsing nearly as well as tags from controlled vocabularies applied by professionals.”
- Lou Rosenfeld
“Building, maintaining, and enforcing a controlled vocabulary is, relative to folksonomies, enormously expensive… - Clay Shirky

Ontology is Overrated
• Classification of the web has failed• Classification itself is filled with bias
and error• Tagging is the solution
• http://www.shirky.com/writings/ontology_overrated.html

Two core questions
• What’s a sustainable way to classify the big messy web?
• Can a loosely organized network of individuals categorizing things for their own interest succeed where the librarians failed?

• “Yes, of course it would be easier. This is what is so radical about tagging — it would be easier because other people would do it for you.”

• “Yes, of course it would be easier. This is what is so radical about tagging — it would be easier because other people would do it for you.”
• Would they? Would you want them to?

• “Tagging bulldozes the cost of classification and piles it onto the price of discovery.”
– Ian Davis

The Big Messy Web
![Page 34: Access 2005 Tagging](https://reader033.vdocuments.us/reader033/viewer/2022061219/5483e162b4af9f1b5b8b4668/html5/thumbnails/34.jpg)
The Big Messy Web
• Ecosystem of Discovery– Email, Blogs, Search, News, Tags
• Constrained Domain– Security, privacy, content, community
• Big Messy Web– Pockets of local structure
![Page 35: Access 2005 Tagging](https://reader033.vdocuments.us/reader033/viewer/2022061219/5483e162b4af9f1b5b8b4668/html5/thumbnails/35.jpg)
Problems with Tagging
• Findability• Collection Management• Accuracy• Scalability
![Page 36: Access 2005 Tagging](https://reader033.vdocuments.us/reader033/viewer/2022061219/5483e162b4af9f1b5b8b4668/html5/thumbnails/36.jpg)
Benefits of Tagging
• Increased re-findability• User engagement & investment• Social interaction & community• Ad hoc user research• More metadata!

The Green Pages
• Expertise Directory• Intranet Application
– Name– Business contact information– Skills– Responsibilities
![Page 38: Access 2005 Tagging](https://reader033.vdocuments.us/reader033/viewer/2022061219/5483e162b4af9f1b5b8b4668/html5/thumbnails/38.jpg)
Features
• Synonyms– Basic authority file – “Tagging tags”– Adding descriptions
• Suggestions– Google Suggest * Flickr
![Page 39: Access 2005 Tagging](https://reader033.vdocuments.us/reader033/viewer/2022061219/5483e162b4af9f1b5b8b4668/html5/thumbnails/39.jpg)
What tagging means
• “I am describing my skills”• “I share skills with others in my
business unit”• “I am describing the skills of my
business unit”• “All/some/few of my skills are
relevant”
![Page 40: Access 2005 Tagging](https://reader033.vdocuments.us/reader033/viewer/2022061219/5483e162b4af9f1b5b8b4668/html5/thumbnails/40.jpg)
Authority, Accuracy and Trust
• “Knowledge is messy”• “There’s duplication/overlap in the skills
list”• “Can we group different kinds of skills?”• “How do you know someone has that skill?”• “How do you validate skills?”• “Are there liability issues?”
![Page 41: Access 2005 Tagging](https://reader033.vdocuments.us/reader033/viewer/2022061219/5483e162b4af9f1b5b8b4668/html5/thumbnails/41.jpg)
Approaches to managing tag sets
• Capture, contain, cleanse– Sacrifice agility in the long-term
• Semi-professionalization– Give engaged taggers tools to help
manage the tag cloud
• Algorithms– Scalable

Summary
• Tagging is augmentation– Re-findability, user engagement
• Tagging is an immature tool• Consider the ecosystem of discovery
– Search, taxonomies & tags playing together
