Web 2.0 and the Emergence of Emergence

A New Version of the Web?

The concept of “Web 2.0” began with a conference brainstorming session between O’Reilly and MediaLive International. Dale Dougherty, web pioneer and O’Reilly VP, noted that far from having “crashed”, the web was more important than ever, with exciting new applications and sites popping up with surprising regularity. What’s more, the companies that had survived the collapse seemed to have some things in common. Could it be that the dotcom collapse seemed marked some kind of turning point for the web, such that a call to action such as “Web 2.0” might make sense. We agreed that it did….

Definition of Web 2.0

“Web 2.0 is the business revolution in the computer industry caused by the move to the Internet as platform, and an attempt to understand the rules for success on that new platform. Chief among those rules is this: Build applications that harness network effects to get better the more people use them.”

Three Trends Yield Better Tools

1. Free and Easy Platforms for Communication and Interaction

2. A Lack of Imposed Structure3. Mechanisms to Let Structure Emerge

Free and Easy Platforms for Communication and Interaction

Emails, mobile phone texting and some types of IM are channels.

Alternative to a channel is called a Platform, such as every Web site, whether on intranet, extranet, or the Internet

Free and easy platforms exist on the web; current popular Web 2.0 platforms like Facebook, MySpace and Blogger. Also Twitter.

A Lack of Imposed Structure

WorkflowsDecision rightInterdependenciesInformation

Throughout history the norm has been to use technology to impose these work structures To define workflows, interdependencies, decision

rights allocation, and information needsERP(enterprise resource planning)CRM(customer relationship management)SCM(supply chain management)

All experienced explosive growth in the mid 90’s By using software to define business processes

It becomes an almost unquestioned assumption that technology should impose the work structures This is reflected in the design of groupware and KM

systems.Software was originally designed to be a

moment by moment accomplishment It has become the most accomplished groupware in

use

Several arguments over the use of technology in workflows came about Whether it should be used to achieve the goal or

simply organize the flow of work Whether it is always appropriate is the key issue

The greatest online encyclopedia, Wikipedia, was created based off a web program called Nupedia.

This encyclopedia was created in a seven stage process

Nupedia Article assignment:

Each article was put through a content screening from whether the person was qualified for writing it to what its content really was.

Lead Review Was blind and confidential

Open Review Open for the general public to view

Lead Copyediting Once it passed open review copyeditors were asked to

copyedit the article Open Copyediting

The article was set aside for a member of the public to review Final Approval and markup

The article was finally posted on Nupedia after final approval

In the fall of 2000 the creators found wikis. Web pages read and edited by the reader

On wikis users and add or delete data from a website they create They are supported by databases which keep track

of all changes.As of 2008 Wikipedia is the largest

reference site in the world. They have 2.4 million articles in English and

hundreds of thousands in other languages.

Due to the advancements of web defined structures companies such as Yahoo! Don’t have to define their structure

The web will do that for them!!

John Allen Paulos

“The internet is the world’s largest library. It’s just that all the books are on the floor.”

Web I.O Search Engine

Web I.O search engines developed by Alta Vista, Infoseek, Excite, etc. provided as alternative to Yahoo’s hierarchy.

“Web Crawling”Analyzed the content of websites

Two Major Problems with Web I.O Search Engines

1. If several Web sites existed on the same topic, it was difficult to determine which was best.

2. It relied on the accuracy of the Web sites’ and pages’ own descriptions.

Google

Google’s Founders: Larry Page and Sergey Brin

Relied on other sites to determine how good a given site was.

First Search engine to view the Web as a community rather than a collection of in individual sites
