Tagging: People-powered metadata for the social web



Another innovative use of tagging comes from weable. a persona finance web site.
where you can tag your financial transactions. Wesabe analyzes tagging patterns
fo come up with recommendation fro merchants. Thus,if you made a purchase at
starbucks, you might see the "coffee" aor "food" as suggestions based on the tags of
other Wesabe users.

Blogging tools suchas WordPress use tags so users have aquick and easy
way to categorize their posts. These tags are picked up by blog aggregators such as
Technorati, whichuses them to discover trends across the blogosphere. At the end of
the book you will find case studie on three kinds of tagging systems: social bookmarking,
personal information management, and media sharing.

Three Perspective on Tagging

Tagging sits at the intersection of three established fields

Information architecture
Social software
Personal information management(PIM)


Like many other disciplines, these three have their frames ofreference through which they view the world.



1) Information Architecture

"the structural design of shared information environments" and "the art and scient of organizing and labeling websites, intranets, online communicaties, and software to support usablitity and finablity.

Information archiectures have focused on using controlled vocabularies, search-and -browse systems, and consistent navigation schemes to achieve this success.

2) Social Software

Social software has a vriety of definitions, ranging from the clincial
("software that enables people to connect through computer-mediated communication")
to the pragmatic("stuff that gets spammed)

As application that people use to communiacate, collaborate, and share online.

It is interested in facilitating group interaction within the system.
They often delight in unanticpiated uses of social application.
of course, it is important for peple to able to find and use information in social software
system too).

3)PERSONAL INFORMATION MANAGEMENT

"refer to both the practice and the study of the activites people perform in order to acquire,
organize, maintaink, retrieve, and use information items such as documents(paper-based and digitial). Web pages, and e-mail messages for everyday used to complete tasks(work-related and not) and fullfill a person's various roles(as parent, employee,friend, member of community,etc)"

In the world of PIM, what's good is what works for you. There are popular computer programs for managing information and methods for keeping yourself on track. These systems help you file, track, and find your information when you need it.


Why Tagging Matters

Humans are organizing machines. our earliest forms of writing were metadata accounts of livestock, stored food, tributes, and other goods etched onto clay tablets.

And since then we've been grouping, sorting, tracking ,and organizing just about everythign we encounter.

crawled, indexed,and organized by search engine.

Over time all communities develop their own vocaularies to describe their members,
their concerns, and their activities

Summary:

Tagging is when users apply keword metadata-or tags to resources sucha s
photos or web pages within a system.

Tagging sits at the intersection of three important fields:

information archiecture, social software, and personal information manamgent.

Recent debates on tagging illustrate the tension points in most tagging systems-
personal verusus social uses, individual versus standard tags, freedom versus control,
and amateur opinions versus those of experts.

Tagging matters because it's popular , multifaced, flexible, and social
It's also made for the stream- the constant flow of information we experience online.
