Web20 Presentation 1107 Web20 Presentation 1107 Presentation Transcript

  • Web 2.0 The New Internet generation Conference 2007 November Avi Rosenthal Strategic Technologies Consultant
  • Presentation Goals
    • Understanding what Web 2.0 is
    • Understanding the concepts and architecture
    • experiencing Web 2.0 by examples
  •   View slide
    • The Domino Fall Down Video slide shows a typical YouTube screen including:
    • The video was created by FlippyCat, probably an amateur and not a media expert.
    • Statistical information about FlippyCat
    • Options for the viewer e.g. adding to PlayList, downloading etc.
    • Flagging option in case of improper content or a content violating Copyrights. Flag is an alert for YouTube to delete the content.
    • The YouTube site could be perceived as a stage for every amateur to create multimedia content. It could be compared to a “Star was Born” style TV programs. The participants in these programs are non professionals performing publicly. The differences: internet communities are larger than TV audience and the content is accessible anytime.
    • I choose deliberately a video on collapsing (Domino Fall Down) by search engine available in YouTube. The reason for choosing a video clip on that topic will be revealed in one of the next slides.
    View slide
  •  
    • The previous video does not look like an amateur uploading content for a community.
    • It looks like a political initiative by Obama's headquarter and not an innocent supporter publishing her political view. It is not the only political video. The next slide includes the URL for Hillary Clinton’s response to Obama Girl song. Videos of politician presenting their views are available in YouTube as well. The point is that politicians think that YouTube is a valid channel for persuading voters to support them. For the younger generation the Web may be the most effective channel.
  •  
  •  
    • The forth video is neither an amateur post and nor a political post.
    • This is one of a group of real training films (black and white) during World War II.
    • The purpose of these films was to explain to people how to protect themselves against the unknown atomic bomb. Ridiculously, the protection method was “duck and cover”. We should remember that no atomic bomb was yet available. This specific film was designed for children.
    • This is an example of a video post that may have historical value .
  • Collapse (Fall down)
    • The year is 2001
    • DotCOM
    • Collapsed
  • Time perspective of The Fall down of 2001
    • Not all DotCom companies collapsed
    • Ebay, Amazon, Google, Ariba, CommerceOne,
    • Long Term: Internet use increased
    • In a brainstorm O’Reilly experts created the term
    • Web 2.0
    • The companies appearing in green were not harmed significantly by the DotCom collapse.
    • For example, Google was established in 1998 and still succeeding.
    • The companies appearing in red were harmed significantly by the DotCom collapse.
    • O’reilly is a company which publish books and e-books and organizes conferences .
    • The participants in this brainstorm were O’reilly experts (including Dale Dougherty the creator of this term) and MediaLive employees.
  • Key brainstorming questions
    • What is the common denominator to the DotCom survivor?
    • What differentiate between the companies which survived 2001 DotCom fall down and the others?
    • Is the 2001 crisis a sign for a new Internet generation? (technologically and culturally)
    • Previous example of a new generation: The change from hardware centered IT to Software centered IT in the 198X posed a huge challenge to the hardware companies like IBM, HP and Digital. Digital did not survive and after selling lines of products to other companies was finally acquired by Compaq.
  • NetScape
    • Webtop instead of Desktop
    • The leading browser of the nineties ( 199 x)
    • The browser was a commercial products
    • control of browser APIs
    • Browser market control as a basis for marketing and selling other software products.
    • Why this model failed?
    • Microsoft
    • The Browser turned into a commodity
    • Focus on layers above the browser infrastructure
    • Netscape is the representative case of Web 1.0 companies.
    • Its business model is similar to business models of non-Web infrastructure software companies. The company was acquired by AOL prior to the DotCom collapse of 2001.
    • The following slides presents the classical representative of Web 2.0: Google. The differences between their model and the classical software vendors model as well as Netscape model can be found easily.
    • Web as a Platform
    • Applications and Data interconnected
    • Applications value dependents upon the dynamic data
    • Services and not software products
    • Do not use model of payments for software products usage
    • Permanent Beta - no versions
    • Leveraging the Search engine service as a central portal for other services
    • Open Social API initiative
    • Innovative search algorithm: Page Rank
    • Page Rank is a Recursive Mathematical Algorithm developed by Larry Page as a student in Stanford University. The idea is to assign rank to a page during a search. The rank is based on weighted index. The index take into account two factors: the number of references to that page and importance.
    • .
    • Social API is a new initiative by Google for common API accessing Social Networks and communities sites.
    • MySpace, Linkidn, Bebo, Plaxo and Orkut joined to Google.
    • Non dedicated Web 2.0 vendors Oracle and Saleforce.com also joined.
    • Blog service as an example
    • A user creates content in Blogger site
    • Free Hosting services and tools for creating and formatting a Blog supplied by Google
    • Pages in Google services includes logo and information about Adsense service for advertisement publishing in the Blog.
    • Win-Win: Google and Blogger –receive money advertisers – advertisement
    • Critical success factors: Google’s ability to direct relevant advertisement, (clicks on advertisements as well as buying activity by readers) Blogger’s ability to attract readers.
    • Problems: inappropriate content (e.g. Phorno) and clicks on advertisements by the blogger and his friends (The prevailing method of payment is based upon the number of clicks on advertisements).
    • The Advertisement and the content are dynamic
  • Web 2.0 O’reilly Map
    • The previous slide depicts the Meme map build in O’reilly’s brainstorming.
    • This is the first and original Web 2.0 Meme map.
    • It should be noted that the model is a developing model with no explicit boundaries.
    • The central part includes the gravitational elements which are definitely the core of Web 2.0
    • The lower part in near to purple color includes principles, ideas and concepts.
    • The upper part (dark green) includes services examples and principles related specifically to some of them.
    • The next slide shows another Meme Map. I would not analyze this specific Meme Map. The purpose of inclusion of that map is to illustrate that there are many models and O’reilly’s model is not the only model.
    • The multitude of models together with the flexible boundaries enables many vendors to label their services and products as Web 2.0, although in some cases they are very far from the Web 2.0 model.
  • Another Meme Map
  • Web 2.0 characteristics
    • Uncontrolled standards based platform
    • Social Computing
    • Sharing Communities
    • Sharing ethics is build in
    • The Hyperlinks are the Network
    • The user controls his data
    • Multimedia
    • Mashups
    • Long tail
  • Mashups
    • The origin of Mashups is in Music : Creating a new song by combining songs.
    • Mashups are applications build by non IT Professionals
    • The User assembles and links services to create an application
    • The services could be data services or could include Business logic functionality
    • The user publish the application in the Web so other users may use it or expand it.
    • Technology: HTML APIs XML and simple Web Services
    • By using JavaScript or other scripting languages the API enables connecting applications or services.
    • The usage of mapping application especially Google Maps as a basic service for a Mashup is very common.
    • To the mapping service the user adds other information such as: whether casting, banking services, restaurant, apartments for rent or for sale etc. or locations for hobbies (see next slide), traveling: flights, cars to rent and landscapes
  • Mashups in action
    • site which includes information and usage statistics about Mashups
    • http://www.programmableweb.com/apis/directory/1?sort=mashups

  •  
  • Long Tail
    • The Web is the sum of all sites not only the sum of most popular sites
    • It is not based upon a principle of reproduced or clowned product
    • It is based upon services which may be used for many different purposes and will be bundled with other services in a Loosely Coupled style.
    • This principle enables implementation of a better advertising model by Google (Adsense) and Yahoo(Overtune)
    • eBay’s model of large number of small transactions utilizes the same principle
  • Characters in Virtual Worlds
    • Not all Wishes are fulfilled
    • Solution: Acquire a virtual identity which may fulfill your dreams
    • Avatar
    • in Hindu philosophy and religion ( and as defined here too ) , an avatar is the physical incarnation of the Supreme ( or an aspect thereof ). " It derives from the Sanskrit word daveed which means " descent " and usually implies a deliberate descent into lower realms of existence for special purposes
    • In virtual worlds the Avatar is 3D representation of a human being (or is his Alter Ego)
  • Virtual Worlds
    • Virtual World is computerized simulation to which Real World laws apply (e.g. Time, Gravitation etc.)

    • Checking, Restoring, Deleting
    • GFDL – GNU Free Documentation License
    • The dispute about the quality of the content of an open encyclopedia vs. the quality of the content of an encyclopedia written by experts is similar to the old dispute between Open Source products and commercial software product development practices (mainly Microsoft).
    • For example, Open Source supporters claim that their products (projects) Security is better than Close code Security, due to the number of people checking that source code. They also claim that the development team of Closed Source products is biased, so it will not be able to check its validity properly.
    • Microsoft’s supporters claim that professionals will develop more secure code than the Open Source community.
    • Research results do not disprove the Open Source community claims.

This method reveals contribution to the community without any content created by the community member. The only content he supplied includes identifying details enabling Alexa software to identify the user activities in other sites.
    • A site's ranking is based on a combined measure of reach and pageviews . Reach is determined by the number of unique Alexa users who visit a site on a given day . Pageviews are the total number of Alexa user URL requests for a site . However, multiple requests for the same URL on the same day by the same user are counted as a single pageview . The site with the highest combination of users and pageviews is ranked #1 .

    • The objectives of participation in Web 2.0 by commercial companies:
    • New advertisement channel of the business products and services
    • A huge number of teenagers and young people participate in Web 2.0 Social Networks. This channel could be the best channel for that purpose for those of them who do not read newspapers and watch TV.
    • example: IBM’s island in SecondLife
    • Customers preferences understanding
    • Reading Blogs and participating in Social Networks is done for understanding potential customers needs and way of thinking.
    • Business related Content creation

    • RDF - A recommendation from the W3C for creating meta - data structures that define data on the Web . It is designed to provide a method for classification of data on Web sites in order to improve searching and navigation
    • The Semantic Web is an extension of the current Web that will allow you to find, share, and combine information more easily . It relies on machine - readable information and metadata expressed in RDF .
    • Semantic Web project of the W3C in which automated methods based on quality metadata are envisaged to replace much human searching of the web . Relies on ontologies, XML and RDF .
