Learning Outcome :
By the end of this session you will be able to 1. Undertake a literature search2. Use the internet for research3. Find theses, conference papers and specialist
materials4. Understand primary sources such as data,
newspapers, official publications
Smart searching techniques
Why do we need a search strategy?
Promotes deeper learning about your question
Leads to better yield of quality researchSaves time in the long run
Smart searching techniques
Keywords may not be enough
If not, select more words by using:
synonyms alternate spelling, translations related terms / words / subjects narrower or broader terms
Smart searching techniques
Most databases offer Thesauri
Smart searching techniques
Examples:
corporate culture: organizational behavior/character
corporate identity merger: acquisition, take-over, fusion, combination
unification profitability: profit, advantage, return on investment, shareholder value
Smart searching techniques
1. Undertake a literature search
Principles, tips and techniques Quick one-stop-shop search Databases Example EbscoHost, Basic Search, Advanced Search,
• Alerts • Saved Searches
Scopus - European Bibliographic database containing abstracts and citations for academic journal
articles. It covers 53 million records | 21,915 titles | 5,000 publishers Web of Science – US Over 90 million records covering 5,300 social science publications in 55 disciplines
Smart searching techniques
Search tipsUse Boolean operators AND, OR, NOTUse truncation and symbols (*, ?) for finding
variant word forms and spellingsFor phrase searching use “ “
In some cases you can specify the fields to search in, e.g. title, subject, keywords

AND OR

Google Scholar -
Good to use in complement to Scopus
including books, conference papers, non-American journals, journals on the fields of strategy, management, international business, education
easy access to published articles, HOWEVER
offers results of inconsistent accuracy,
inadequate, and less often updated – no reliable impact factor
frequency of its updates is unknown
Google Scholar is vulnerable to spam
uses a PAGE RANK ALGORITHM
Smart searching techniques
PageRank is a link analysis algorithm and it assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within these.

GOOGLE SCHOLAR
• Free and accessible for scholarly research• Includes journal and conference papers, theses and
dissertations, academic books, pre-prints, abstracts, technical reports and other scholarly literature from all broad areas of research
• Login via EZProxy• UCT has access to online subscriptions
• Please consult the following Youtube video:• “What Google Scholar can do for you” http://www.youtube.com/watch?v=XcrM4sX5W8c
Smart searching techniques
GOOGLE SCHOLAR
Uses natural language Tips and tricks Automatic sorted by relevance Determined by the number of citations May not be most relevant to your search Refine by year – click on sort by date” or “since xxxx” or
“custom range”
Smart searching techniques
GOOGLE SCHOLAR
Inverted commas for phrase Boolean operators AND OR Google uses dash instead of NOT For specific authors: author:Smith (no spaces) similarly for specific formats Format:pdf and site:nytimes.com election SFX – availability on campus and logged in Librarylink allows to access digital repositories
Smart searching techniques
GOOGLE SCHOLAR
Underneath each result : useful links Closely related articles Cite – 3 different formats to copy and paste From here: Import directly to Endnote and/or Refworks Save : if you have created a Google account (gmail) You will have “MY Library” in which you can collect
Smart searching techniques
GOOGLE SCHOLAR
Such as electronic thesis collectionType in author’s surname and thesis titleE.g Fleishman “remembering in the
postcolony”Scroll down until you get the thesis linkTry authors surname and the affiliation, such
as University of Cape Town, University of Pretoria

2. Using the internet for your research
The following slides are taken from a “Web Searching workshop” which was facilitated by Peter Underwood (2012) and Mary Nassimbeni (2012)
Smart searching techniques
Internet SearchingThe information retrieval problem
• Mismatching of vocabularies – Synonyms: e.g. railway / railroad car / automobile– Polysemes: e.g. table (furniture) / table (data presentation)
• Queries are ambiguous, and are rarely complete – or accurate – statements of need
• Document descriptions and texts do not always reflect content and intended use accurately
• The user is the ultimate judge of what seems relevant -- but we don’t know much about how this judgment is made
Smart searching techniques
Search structure
• keywords describing important concepts– synonyms– phrases
• linkages between keywords• limits on what is retrieved
– language– time period– country– format
• quantity
Smart searching techniques
Search engine choice • South African-based search engine, useful for locating national and regional information

Master site for South African search engines: http://www.searchenginecolossus.com/SouthAfrica.html
• Focus on publication form http://www.bpubs.com

Meta Search Engine
• Allows searching of multiple search services• Do not normally hold their own data• May be customised to use selected services• Example:
http://www.dogpile.com

Evaluating web sites and web materialTraditional criteria to be applied– Accuracy– Authority– Objectivity– Currency– CoverageAdditional challenges
Smart searching techniques
How to go about evaluationAdvocacy, orgBusiness, comInformational, edu ac govNews, usu comPersonal, often a ~
Use the checklist: the more often you can answer ‘yes’ the more likely it is that the site/material is reliable
Smart searching techniques
Checklist
Authority• Can you identify organisation/company/person
responsible?• Is there a link describing goals, purpose, nature of
organisation?• Are there contact details?
Smart searching techniques
Accuracy• Are sources for any factual information listed so they can be
verified?• Can you detect some sort of quality control? – look at
grammar, spelling etc.• Are charts, graphs clearly labelled and easy to read?
Smart searching techniques
Objectivity• Are biases clearly stated?• Is it easy to distinguish between informational and
advertising content?
Smart searching techniques
CurrencyAre there dates to indicate
• When the page was written?• When it was placed on the web?• When it was last revised?
Smart searching techniques
Coverage• Is there an indication that the page has been completed?• Is there a print equivalent?• Is it clear what topics the page intends to address?
Smart searching techniques
Contemporary sources, but do remember the evaluation criteria
Blogs http://www.google.com/blogsearchhttp://www.findblogs.com/
Twitterhttp://www.twitter.com
Facebookhttp://www.facebook.com

– Accuracy– Authority– Objectivity– Currency– Coverage
