Transcript of "T L W Smart Searching"

  1. 1. Finding the Needle in a Haystack “ Smart Internet Searching” Pam Krambeck Papillion-La Vista Schools [email_address] Web site: plv . ishareinfo . org/pkrambeck (handout, docs & presentation under documents)
  2. 2. Gathering Internet Resources & Information With Students: <ul><ul><li>Finding information on the internet is not unlike using a rake to find a needle in a field full of haystacks. </li></ul></ul><ul><ul><li>Now, imagine the haystacks getting bigger by the day!   </li></ul></ul><ul><ul><li>If you could you would use a special magnet that would automatically, quickly and effortlessly attract that needle for you. </li></ul></ul>
  3. 3. Gathering Internet Resources & Information With Students: <ul><ul><li>The &quot;needles&quot; in this metaphor are the key information pieces you or your students seek for a project or research. </li></ul></ul><ul><ul><li>“ Smart Searching Techniques” will be the magnet that attracts the information you are seeking &quot;from the enormous haystack of information&quot; . </li></ul></ul>
  4. 4. Search Engines Serve a Role— A Limited Role <ul><ul><li>Commonly referred to as &quot;spiders&quot; or &quot;crawlers&quot; </li></ul></ul><ul><ul><li>Search the web for new pages at all times </li></ul></ul><ul><ul><li>Are automated and index many sites </li></ul></ul><ul><ul><li>Often find information not listed in directories </li></ul></ul><ul><ul><li>Often pull up unrelated information for the topics </li></ul></ul><ul><ul><li>Web Search Engines Include: </li></ul></ul><ul><ul><ul><li>Yahoo Search Engine (it also has a directory) </li></ul></ul></ul><ul><ul><ul><li>Lycos </li></ul></ul></ul><ul><ul><ul><li>Ask.com </li></ul></ul></ul><ul><ul><ul><li>Google </li></ul></ul></ul><ul><ul><ul><li>MSN Search </li></ul></ul></ul><ul><ul><ul><li>Alta Vista </li></ul></ul></ul>
  5. 5. Public Search Engines <ul><ul><li>Use advertising to finance their sites </li></ul></ul><ul><ul><li>Display search results based on predetermined factors--could be advertising dollars </li></ul></ul>
  6. 6. Search Directories <ul><li>index a site based on an independent description </li></ul><ul><li>do not spider your site to gather information about it </li></ul><ul><li>organizes sites by subject </li></ul><ul><li>usually maintained by humans instead of software </li></ul><ul><li>web search directories include: </li></ul><ul><ul><ul><li>Yahoo Search Directory </li></ul></ul></ul><ul><ul><ul><li>Yahoo! Kids (formerly Yahooligans!) </li></ul></ul></ul><ul><ul><ul><li>About.com </li></ul></ul></ul>
  7. 7. Refine Your Search--Use Advanced Features <ul><li>narrow search results </li></ul><ul><li>located to the right of the search blank at most sites </li></ul><ul><li>provide a number of options </li></ul><ul><li>specify an exact phrase to include or exclude </li></ul><ul><li>examples: Google , Yahoo </li></ul>
  8. 8. Search Engine Math <ul><li>Addition: Using the + Symbol </li></ul><ul><li>For example, to find pages that have references to both Nebraska and Buffalo Bill Cody on the same page. You could search this way: </li></ul><ul><li>+Nebraska +Buffalo Bill Cody </li></ul><ul><ul><li>Results: 1,020,000 vs 233,000 </li></ul></ul><ul><li>Subtraction: Using The - Symbol to Subtract Using the - symbol will find pages that have one word but not another. </li></ul><ul><ul><li>For example, to find information about penguins </li></ul></ul><ul><ul><li>not including pages relating to the hockey team. You could search this way : penguins -hockey </li></ul></ul><ul><ul><li>Results: 13,400,000 vs 2,270,000 add “macaroni penguin”+ habitat (683) </li></ul></ul><ul><li>Multiplication: Quotation marks “ ” work like multiplication--they allow you to combine words into a searchable phrase </li></ul><ul><ul><li>For example, if you were looking for information on Platte River State Park the easiest way to find information that contains this phrase is to search: </li></ul></ul><ul><ul><li>“ Platte River State Park” </li></ul></ul><ul><ul><li>Results: 1,280,000 vs 777 </li></ul></ul>
  9. 9. Boolean Searching <ul><li>used for searching through traditional databases </li></ul><ul><li>comfort level in using what is already familiar </li></ul><ul><li>Boolean commands must be in uppercase </li></ul><ul><li>OR: used to allow any of the specified search terms to be present on the web page </li></ul><ul><li>Buffalo Bill Cody OR William Cody OR Buffalo Bill </li></ul><ul><li>AND: used to require that all search terms be present on the web page--using the + symbol is generally a good alternative. </li></ul><ul><li>Wild West Show AND Buffalo Bill </li></ul><ul><li>NOT: used to require that a search term NOT be present on web pages listed in results. It can also be described as an Exclude search. </li></ul><ul><li>Buffalo Bill Cody NOT Wyoming </li></ul><ul><li>More Resources </li></ul><ul><ul><li>http://www. searchengineshowdown .com/newsarchive/000629.shtml </li></ul></ul><ul><ul><li>http://library.albany.edu/internet/boolean.html </li></ul></ul><ul><ul><li>http://www.infotoday.com/searcher/feb98/story1.htm </li></ul></ul>
  10. 10. Domain Specific Searches <ul><li>Searching specific domains is helpful if you want to exclude .com sites </li></ul><ul><li>Know your domains: .edu, .gov, .org, com </li></ul><ul><li>Google & Others: use site:domain in the search box </li></ul><ul><ul><li>Example for Google: “Marzano’s Strategies” + site:edu </li></ul></ul><ul><li>Alta Vista : use host:domain in the search box </li></ul><ul><ul><li>Example for Alta Vista: “Marzano’s Strategies” + host:edu </li></ul></ul>
  11. 11. What’s in a (Domain) Name <ul><li>.com and .net are examples of extensions </li></ul><ul><li>extensions are an important part of domain name </li></ul><ul><li>extensions shows who publishes the domain </li></ul><ul><li>common extensions </li></ul><ul><ul><li>.edu Educational organization (most US universities) </li></ul></ul><ul><ul><li>.k12 US school site (not all US schools use this) </li></ul></ul><ul><ul><li>.ac Academic institution (outside of US) </li></ul></ul><ul><ul><li>.sch School site (some schools outside of the US use this) </li></ul></ul><ul><ul><li>.com Company (usually .co in the UK) </li></ul></ul><ul><ul><li>.org Any organization </li></ul></ul><ul><ul><li>.gov Government agency </li></ul></ul><ul><ul><li>.net Network </li></ul></ul><ul><ul><li>.mil Military institution </li></ul></ul><ul><li>extensions can also include country codes </li></ul><ul><ul><li>.uk, .ca, .za </li></ul></ul><ul><ul><li>For a complete list refer to the Computer User High-Tech Dictionary: http://www.computeruser.com/resources/dictionary/noframes/nf.domains.html </li></ul></ul>
