  7. What is Web 2.0? • New services and software – Collectively known as Web 2.0 • Transforming the web 1.0 from a predominately “READ ONLY” medium to one where anyone can publish and share content and easily collaborate with others Web 2.0

  11. Web 2.0 Web 2.0

  12. Web 2.0 Web 2.0

  13. Web 2.0 Web 2.0

  14. Web 2.0 • The more explicit synonym "Participatory Web", emphasizing tools and platforms that enable the user to: • tag, • blog, • comment, • modify, • augment, • select from, • rank, and • generally talk back to the contributions of other users and the general world community Web 2.0

  15. Web 2.0 • What was it that made us identify one application or approach as "Web 1.0" and another as "Web 2.0"? • You can visualize Web 2.0 as a set of principles and practices that tie together a veritable solar system of sites that demonstrate some or all of those principles, at a varying distance from that core. Web 2.0

  16. Web 2.0 Web 2.0

  17. Web 2.0 Web 2.0

  18. Web 2.0 Membership at social networking sites such as Facebook and MySpace is exploding. In June, 2 out of every 3 people online visited a social networking site. Since January 2004, the number of people visiting or taking part in one of the top online social networks has grown by over 109% (primarily driven by MySpace). Social networking sites are now close to eclipsing traffic to the giants - Google and Yahoo. Web 2.0

  19. Web 2.0 • The bursting of the dot-com bubble in the fall of 2001 marked a turning point for the web • 2004 - The concept of "Web 2.0" began with a conference brainstorming session between O'Reilly and MediaLive International • Some commentators regard reputation-based public wikis, such as Wikipedia, as pioneering examples of Web 2.0/Participatory Web technology. Web 2.0

  20. Web 2.0 • The phrase Web 2.0 in 2004 to refer to a supposed second-generationof Internet-based services that let people collaborate (participatory) and share information online in perceived new ways — such as:- • social networking sites, • wikis, • communication tools, • folksonomies Web 2.0

  21. Web 2.0 • Example: • Web 1.0  Web 2.0 • DoubleClick --> Google AdSense • Ofoto --> Flickr • Akamai --> BitTorrent • mp3.com --> Napster • Britannica Online --> Wikipedia • personal websites --> blogging • Evite --> upcoming.org and EVDB • domain name speculation --> search engine optimization page views --> cost per click • screen scraping --> web services • Publishing --> participation • content management systems --> wikis • directories (taxonomy) --> tagging ("folksonomy") • Stickiness --> syndication Web 2.0

  22. Web 2.0 • What was it that made us identify one application or approach as "Web 1.0" and another as "Web 2.0"? Web 2.0 - The Web As Platform • doesn't have a hard boundary, but rather, a gravitational core. • a set of principles and practices that tie together a veritable solar system of sites that demonstrate some or all of those principles, at a varying distance from that core. Web 2.0

  23. Web 2.0 • Netscape vs. Google • Netscape- the standard bearer for Web 1.0, • Google - the standard bearer for Web 2.0, • Netscape : • the web as platform" in terms of the old software paradigm: • Netscape navigator-web browser, a desktop application. • use their dominance in the browser market to establish a market for high-priced server products. Web 2.0

  24. Web 2.0 • Netscape vs. Google • In the end, both web browsers and web servers turned out to be commodities, and value moved "up the stack" to services delivered over the web platform. • At bottom, Google - database management. • Google isn't just a collection of software tools, it's a specialized database. Web 2.0

  25. Web 2.0 • The Web 2.0 lesson: • leverage customer-self service and algorithmic data management to reach out to the entire web, to the edges and not just the center, to the long tail and not just the head. Web 2.0

  26. Web 2.0 • Other web 2.0 success stories demonstrate this same behavior. • eBay enables occasional transactions of only a few dollars between single individuals, acting as an automated intermediary. • Napster (though shut down for legal reasons) built its network not by building a centralized song database, but by architecting a system in such a way that every downloader also became a server, and thus grew the network. Web 2.0

  27. Web 2.0 • 2. Harnessing Collective Intelligence • Akamai vs. BitTorrent • Akamai is optimized to do business with the head/center (big servers), not the tail/edges (PC). • While it serves the benefit of the individuals at the edge of the web by smoothing their access to the high-demand sites at the center, it collects its revenue from those central sites. • Akamai must add servers to improve service Web 2.0

  28. Web 2.0 • BitTorrent • P2P, takes a radical approach to Internet decentralization. • Every client is also a server, • Files are broken up into fragments that can be served from multiple locations, • The network of downloaders to provide both bandwidth and data to other users. • The more popular the file, in fact, the faster it can be served, as there are more users providing bandwidth and fragments of the complete file. Web 2.0

  29. Web 2.0 • BitTorrent thus demonstrates • a key Web 2.0 principle: the service automatically gets better the more people use it. • Every BitTorrent consumer brings his own resources to the party. • "architecture of participation", • a built-in ethic of cooperation, in which the service acts primarily as an intelligent broker, connecting the edges to each other and harnessing the power of the users themselves. Web 2.0

  30. Web 2.0 • The central principle behind the success of the giants born in the Web 1.0 era who have survived to lead the Web 2.0 era appears to be this, • that they have embraced the power of the web to harness collective intelligence: • Yahoo!,Web 1.0 success story, was born as a catalog/directoryof links, an aggregation of the best work of thousands, then millions of web users. • Yahoo!Web 2.0 - business of creating many types of content, a portal to the collective work of the net's users remains the core of its value. Web 2.0

  31. Web 2.0 • Amazon and Barnesandnoble.com sell :- • the same products • they receive the same product descriptions, cover images, and editorial content from their vendors. • But Amazon has made a science of user engagement. • more user reviews, • invitations to participate in varied ways on virtually every page. • use user activity to produce better search results. Web 2.0

  32. Web 2.0 • Barnesandnoble.com:- • search is likely to lead with the company's own products, or sponsored results. • With an order of magnitude more user participation, it's no surprise that Amazon's sales also outpace competitors. Web 2.0

  33. Web 2.0 • Now, innovative companies that pick up on this insight and perhaps extend it even further, are making their mark on the web: • Wikipedia, an online encyclopedia based on the unlikely notion that an entry can be added by any web user, and edited by any other, is a radical experiment in trust, • This is a profound change in the dynamics of content creation! – Information is transitional Web 2.0

  34. Web 2.0 • Sites like del.icio.us and Flickr, two companies that have received a great deal of attention of late, have pioneered a concept that some people call - folksonomy • Classifying Web sites by the user community rather than by taxonomy professionals. • provide a democratic tagging system that reflects the opinions of the general public • a style of collaborative categorization of sites using freely chosen keywords – Bully, Malaysia, students, often referred to as tags. • a taxonomy (controlled vocabulary ) in that the authors of the labeling system are often the main users (and sometimes originators) of the content to which the labels are applied.

  39. Web 2.0 • Folksonomy- a style of collaborative categorization of sites using freely chosen keywords, often referred to as tags. • Tagging allows for the kind of multiple, overlapping associations that the brain itself uses, rather than rigid categories. • In the canonical example, a Flickr photo of a puppy might be tagged both "puppy" and "cute"--allowing for retrieval along natural axes generated user activity Web 2.0

  40. Web 2.0 • What are tags?You can give your photos a "tag", which is like a keyword. • Tags help you find photos which have something in common. • You can assign as many tags as you wish to each photo. Web 2.0

  42. Web 2.0 • Blogging and the Wisdom of Crowds • A weblog, which is usually shortened to blog, is a type of website where entries are made (such as in a journal or diary), displayed in a reverse chronological order. • Blogs often provide commentary or news and information on a particular subject, such as food, politics, or local news; some function as more personal online diaries. Web 2.0

  43. Web 2.0 • A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. • Most blogs are primarily textual although some focus on:- • photographs (photoblog), • videos (vlog), • audio (podcasting).- Web 2.0
