Reflection on web2.0

  1. 1. Credible Sources of Info in Web2.0- A Reflection by Pray
  2. 2. Problem with Search Engine like Google and Yahoo <ul><li>Do not distinguish between academic and personal source </li></ul><ul><li>Search only key words or phrases and returns result. </li></ul><ul><li>Since anyone can post/edit anything in Wiki, it is not a reliable source; so is the most blogs and forums in the net. </li></ul><ul><li>Using a database, like EbscoHost or ProQuest, is the best way to find a credible source because these databases weed out articles that are not very reliable. </li></ul>
  3. 3. The way forward….. <ul><li>Instead of Google, one should use Google Scholar. </li></ul><ul><li>Still better is using research databases such as SciVerse Scopus, PubMed, ProQuest, EBSCOhost </li></ul><ul><li>These databases weed out articles that are not very reliable; hence above databases list reliable sources. </li></ul>
  4. 4. Google Scholar <ul><li>Technical reports, conference presentations, and journal articles are included, as are links to Google Books. </li></ul><ul><li>However, Google Scholar, like regular Google, is created by Google’s “robots” which scan different webpages for scholarly material, with less care going into the journals that publish these articles. </li></ul>
  5. 5. Google Scholar <ul><li>Incapable to list all of the articles as scholarly databases do. </li></ul><ul><li>Broken links and repetitive results are common. </li></ul><ul><li>A better approach is to use it, though, in combination with other subject-specific databases discussed hereafter. </li></ul>
  6. 6. SciVerse Scopus <ul><li>Provides authentic database containing abstracts and citations for scholarly journal articles. </li></ul><ul><li>SciVerse Scopus, as narrated by itself is, integrating ScienceDirect, Scopus, SciTopics and targeted Web content, with community developed applications SciVerse is a groundbreaking platform that gives you our data, your way . </li></ul><ul><li>Not free resource; one has to pay for search. </li></ul>
  7. 7. PubMed <ul><li>PubMed comprises over 20 million citations for biomedical literature from MEDLINE, life science journals, and online books. </li></ul><ul><li>It also provides access to additional relevant Web sites and links to the other NCBI molecular biology resources. </li></ul><ul><li>It is a free resource. </li></ul>
  8. 8. ProQuest <ul><li>Results vetted, reliable information. </li></ul><ul><li>One has three option to search: </li></ul><ul><ul><ul><ul><li>By Library Type: </li></ul></ul></ul></ul><ul><ul><ul><ul><li>By Product Line: </li></ul></ul></ul></ul><ul><ul><ul><ul><li>By Subject </li></ul></ul></ul></ul><ul><li>For more information one may visit </li></ul><ul><li>Not free resource; one has to pay for search. </li></ul>
  9. 9. EBSCOhost <ul><li>Online database. </li></ul><ul><li>Reliable. </li></ul><ul><li>Not free resource; one has to pay for search. </li></ul>
  10. 10. Who is creator? <ul><li>Check for name of author(s) and their affiliation. </li></ul><ul><li>Does search engine immediately spot them in the first page? </li></ul><ul><li>Check for “About us” page. </li></ul>
  11. 11. Scan the document & look for….. <ul><li>The reference list —good article usually cite references. </li></ul><ul><li>Also look for whether references are mostly from a single/common author(s). </li></ul>
  12. 12. Be cautious if….. <ul><li>The author(s) provide a one-sided view. </li></ul><ul><li>Discard if you identify any prejudiced content in the article. </li></ul><ul><li>Check for outdated references only. </li></ul>
  13. 13. Acknowledgements <ul><li>Sites of Google Scholar, SciVerse Scopus, PubMed, ProQuest, EBSCOhost. </li></ul>
