  1. Beyond Google Sean Barr Bernie MathiasJan 30th, 2013

  2. Outline of Session • Using Google to the fullest/ Google Scholar • Alternatives to Google • The Deep Web • Directories & Subject Gateways

  3. Overview of the Web • Hundreds of millions of sites- Billions of pages • Browsers –Firefox, Chrome, Safari, IE etc • Search Engines such as Google – use Spiders and Crawlers to extract data • Indexed and Stored in the Search Engine database • You search the database -not the web.

  4. Search engines • Use a search engine when you have a clear idea what you are looking for on a specific subject. • Use more search terms and more specific terms to give you more specific results. • Search engines usually link your search terms with AND (i.e. search for all terms). • Use quote marks to search for a specific phrase (e.g. “climate change”).

  5. Search tips • filetype :ppt e.g. Horsemeat:ppt • Site :nhs.uk e.g. Horsemeat :site:nhs.uk • ~ tilde for synonyms e.g ~Horsemeat • - minus . Exclude pages that contain it e.g. • burgers –Horsemeat • 5. Verbatim • 6. Instant

  6. More search tips • Repeat your key search terms: • chocolate production UK francebelgium • chocolate production UK francebelgiumbelgiumbelgium • different results • Change the order of your terms: • chocolate production Belgium Switzerland • production Belgium Switzerland chocolate • different results

  7. Google is now more than just Google

  8. Two Worlds Collide • Facebook'sGraph Search is as much a search engine as Google's Google+ is a social network. • “Social Search” • Google coming at it from the “Search”side. • Facebook from the “Social” side

  9. Facebook Graph Search –Privacy fears

  10. Google Scholar Provides a search of scholarly literature across many disciplines and sources, including theses, books, abstracts and articles Also features Alerts, Metrics and Citations

  11. Google Scholar Use with caution! • searches “scholarly literature” not the whole web • not restricted to peer-reviewed content • includes “cited by” and “Related Articles” links • secrecy about coverage; important exclusions • “library links” option (in Preferences) • “import into EndNote” option (in Preferences)

  12. More Academic Options • Iseek - Clusters results into topics, people, places, organisations, date & time. • “Education” option – more research oriented pages

  13. All Googled out ? DDG for example doesn’t personalize, filter or track. Some report better results than with Google.

  14. Multi-search engines or ‘One site to Search them all’ • Zuula • http://www.zuula.com • Runs your search through a range of search tools one by one • Order can be customised • MrSapo • http://www.mrsapo.com • Similar to Zuula but with more options

  15. The Deep Web

  16. The Deep Web • Visible Web: the web pages that a standard search engine can find and index. • Deep Web: everything else.aka: The Invisible Web; The Hidden Web;Deepnet; DarkNet; Undernet

  17. Deep Web resources • Dynamic content • Unlinked content • Subscription / password-protected content • Limited access / robot exclusions • Multimedia content • Gopher / FTP content

  18. Searching the Deep Web • You have probably used the invisible web without being aware of it. • Library catalogues • Electronic journals • Bibliographic databases

  19. Web Directories & Subject Gateways • Useful for finding web sites rather than specific pages or pieces of text. • Manually compiled. • Quality control: academics & librarians. • Open Directory Project: http://www.dmoz.org/ • Yahoo Directory: http://dir.yahoo.com/

  20. Mailing Lists • JISCmailhttp://www.jiscmail.ac.uk/ has thousands of groups covering many categories. • Useful way to keep up to date with developments in your subject areas. • Can subscribe to groups on a very wide range of topics and join in debates and discussions.

  21. Science/Academic Search Engines • RefSeek – http://www.refseek.com Scirus – http://www.scirus.com Scientific WebPlus - http://scientific.thomsonwebplus.com Science.gov – http://www.science.gov WorldWideScience.org - http://worldwidescience.org Science Accelerator - http://www.scienceaccelerator.gov
