Search engine -final Presentation Transcript

  • 1.  
  • 2.
    • A software program that searches a database and gathers and reports information that contains or is related to specified terms.
    • A website whose primary function is providing a search engine for gathering and reporting information available on the Internet or a portion of the Internet.
  • 3.
    • Wanderer
    • Crawler
    • Robot
    • Worm
    • Spider
  • 4.
    • The documents and web addresses are collected and sent to the search engines indexing software.
    • The indexing software extracts information from the documents, storing it in a database.
  • 5.
    • When you perform a search by entering keywords, the database is searched for the document that match
  • 6.
    • Cuil (pronounced 'cool')
    • This search engine was founded by ex-Google staff. It is spartan, like Google and DuckDuckGo. But there are differences beyond the black background. Cuil uses a column format like a newspaper, and it offers both tabled and columned groups to help your searching. The results are not ranked in the same currents events/popularity sequence that Google is known for. But Cuil.com can really be helpful in choosing research directions when you are just discovering a topic for the first time.
  • 7.
    • Ask (aka 'Ask Jeeves')
    • The Ask/AJ/Ask Jeeves search engine is a longtime name in the World Wide Web. The super-clean interface rivals the other major search engines. The results groupings are what really make Ask.com stand out. The presentation is arguably cleaner and easier to read than Google or Yahoo! or Bing, and the results groups seem to be more relevant.
  • 8.
    • Duck Duck Go
    • At first, DuckDuckGo.com looks like Google. But there are many subtleties that make this spartan search engine different. DuckDuckGo has some slick features, like 'zero-click' information (all your answers are found on the first results page). DuckDuckgo offers disambiguation prompts (helps to clarify what question you are really asking). And the ad spam is much less than Google. Give DuckDuckGo.com a try... you might really like this clean and simple search engine.
  • 9.
    • Clusty (aka 'Yippy')
    • Clusty is a Deep Web engine that searches other search engines for you. Unlike the regular Web, which is indexed by robot spider programs, Deep Web pages are usually harder to locate by conventional search. That's where Clusty becomes very useful. If you are searching for obscure hobby interest blogs, obscure government information, tough-to-find obscure news, academic research and otherwise-obscure content, then Clusty is your tool.
  • 10.
    • Webopedia
    • Webopedia is one of the most useful websites on the World Wide Web. Webopedia is an encyclopedic resource dedicated to searching techno terminology and computer definitions. Teach yourself what 'domain name system' is, or teach yourself what 'DDRAM' means on your computer. Webopedia is absolutely a perfect resource for non-technical people to make more sense of the computers around them.
  • 11.
    • Yahoo!
    • Yahoo! is several things: it is a search engine, a news aggregator, a shopping center, an emailbox, a travel directory, a horoscope and games center, and more. This 'web portal' breadth of choice makes this a very helpful site for Internet beginners. Searching the Web should also be about discovery and exploration, and Yahoo! delivers that in wholesale quantities.
  • 12.
    • Bing
    • Bing is Microsoft's attempt at unseating Google. Bing used to be MSN search until it was updated in summer of 2009. Touted as a 'decision engine', Bing tries to support your researching by offering suggestions in the leftmost column, while also giving you various search options across the top of the screen. Things like 'wiki' suggestions, 'visual search', and 'related searches' might be very useful to you. Bing is not dethroning Google in the near future, no. But Bing is definitely worth trying.
  • 13.
    • Google
    • Google is the undisputed king of 'spartan searching'. While it doesn't offer all the shopping center features of Yahoo!, Google is fast, relevant, and the largest single catalogue of Web pages available today. Make sure you try the Google 'images', 'maps' and 'news' features... they are outstanding services for locating photos, geographic directions, and news headlines.
