Don't miss important references

  1. 1. Don’t Miss Important References! RDF InformationLiteracy
  2. 2. Don’t Miss Important References! • When you are new to literature searching it’s easy to miss important references. • Here’s a few simple techniques to use when searching databases that should help you to find most of the references you need. RDF InformationLiteracy
  3. 3. Wildcard Characters and Truncation RDF InformationLiteracy  Use wildcards (*, ?, $) for word variations, e.g.  singular / plural, nouns / verbs, UK / US spellings  The asterisk (*) represents any group of characters, including no character  The question mark (?) represents any single character  The dollar sign ($) represents zero or one character
  4. 4. Wildcard Characters and Truncation RDF InformationLiteracy Some Examples:
  5. 5. Phrase Searching RDF InformationLiteracy  To search for an exact phrase, enclose the phrase in quotation marks  For example, the search query "energy conservation" will retrieve all references that contain the exact phrase energy conservation
  6. 6. Boolean Operators RDF InformationLiteracy Use Boolean operators to combine your search terms (e.g. AND, OR, NOT, NEAR, etc)
  7. 7. Boolean Operators RDF InformationLiteracy
  8. 8. Controlled Vocabulary RDF InformationLiteracy Find any controlled vocabulary available for the subject area you are researching People who index information for a database will use controlled vocabulary from a list of keywords, often listed online, to: • Provide a consistent method of finding information that uses different terms for the same concepts • Find information on a broader or narrower aspect of a particular subject
  9. 9. Controlled Vocabulary RDF InformationLiteracy • There are two main kinds of controlled vocabulary tools used in databases: subject headings and thesaurus terms
  10. 10. Controlled Vocabulary RDF InformationLiteracy Subject Headings • Describe the main focus of the content of a publication • Provide terms which bring together different ways of defining a subject e.g. MESH subject headings from the PubMed database
  11. 11. Controlled Vocabulary RDF InformationLiteracy Thesaurus Terms • Thesauri list words grouped together according to similarity of meaning • Thesauri list not only equivalent terms but also narrower, broader terms and related terms e.g. Thesaurus terms from the Compendex database
  12. 12. Conclusion RDF InformationLiteracy In order to avoid missing important references, use these search techniques – either singly, or by combining them in a search: • Wildcard characters and truncation • Phrase searching • Boolean search operators • Controlled vocabulary (subject headings and thesaurus terms)
