Push technologies l.jpg
Push Technologies Portals, Search Engines, Web Servers, Bots, Shopping Carts…

  • An automated delivery of specific and current information from a Web server to the user’s computer’s hard drive (Webcasting is an implementation of push technology)

  • May be used to provide information on

    • Health benefit updates

    • Employee awards

    • Changes in corporate policies

    • Other relevant information


Bots or intelligent agents l.jpg
Bots or Intelligent Agents Portals, Search Engines, Web Servers, Bots, Shopping Carts…

  • The word Bot is derived from 'robot', and refers to a computer program performs functions such as information gathering, information filtering, or mediation (running in the background) on behalf of a person or entity.

    • A bot (sometimes called an agent) typically searches the Internet, gathers information relevant to your query or interest, and presents it on a scheduled basis, hourly, daily, weekly, etc.


Some examples of agents l.jpg
Some Examples of Agents Portals, Search Engines, Web Servers, Bots, Shopping Carts…

  • Bargain Finder - an intelligent agent for comparison music CD shopping

  • AdHound - searches the classifieds of hundreds of US newspapers daily with relevant ads emailed

  • AuctionBot - a multi-purpose Internet Auction server developed at the University of Michigan. The AuctionBot can be used to create automated Internet auctions according to your specifications, or bid in existing AuctionBot auctions.


Search engines l.jpg
Search Engines Portals, Search Engines, Web Servers, Bots, Shopping Carts…

  • A special kind of Web page software that finds other Web pages that match a word or phrase the user enters

  • Contains three major program parts:

    • Spider, crawler, or “bot” – a program that goes to every page or representative page on every web site that wants to be searched

    • Catalog – a program that creates a huge “index” of what is found

    • Search engine utility – a program that receives your search requests, compares it to the index, and provides search results to you

How Search Engines Work? Portals, Search Engines, Web Servers, Bots, Shopping Carts…

  • Crawler-based search engines

    • Create their listings automatically (e.g., Google, HotBot)

  • Human-Powered Directories

    • Depends on humans for its listings (e.g., Yahoo)

  • Hybrid search engines

    • Both types of results presented (e.g., Yahoo presents directories and Google results)


Internet portals l.jpg
Internet Portals Portals, Search Engines, Web Servers, Bots, Shopping Carts…

  • Portal is a new term, generally synonymous with gateway, for a World Wide Web site that is or proposes to be a major starting site for users when they get connected to the Web or that users tend to visit as an anchor site.

    • Typical services offered by portal sites include

      • a directory of Web sites, a facility to search for other sites, news, weather information, e-mail, stock quotes, phone and map information, and sometimes a community forum.

      • Excite is among the first portals to offer users the ability to create a site that is personalized for individual interests.

    • The term portal space is used to mean the total number of major sites competing to be one of the portals.


Types of portals l.jpg

  • Specialized or niche portals.

    • Examples of niche portals include Garden.com (for gardeners), Fool.com (for investors), and SearchNT.com (for Windows NT administrators).

    • Hsupply.com (hospitality management industry B2B portal)

  • Stickiness l.jpg
    Stickiness Portals, Search Engines, Web Servers, Bots, Shopping Carts…

    • "Stickiness" refers to a Web site's ability to attract engaged, repeat visitors who spend more and more of their time on a given site instead of briefly alighting and then flitting off to some other corner of cyberspace.

      • The two most important measurements of what a Web site has to offer advertisers are

        • ad views and the average time each visitor spends on the site.

          • If you can make your visitor spend more time at your site, they will view more ads and they can be considered more loyal to the site and presumably somewhat more likely to click on the ads and patronize advertisers.


    Common stickiness approaches l.jpg
    Common Stickiness Approaches Portals, Search Engines, Web Servers, Bots, Shopping Carts…

    • The most common stickiness approaches are:

      • Providing content that the user really wants

      • Allowing the user to personalize the site (Yahoo, Excite, and MSN Network, for example)

      • Building online communities in which users post information or form discussion groups (Yahoo, Geocities)

      • Inviting user feedback in response to columnists (ZDNet)

      • Adding games to the site (Yahoo)

      • Using extensive hypertext cross-references to other parts of the site (whatis.com and many others)
