GNED008 Week 3 Forming Research Questions & Concept Mapping Catherine Kwok Library Reference

Outline Isn’t Google enough? Analyze a research topic How to convert a topic into keywords? – related terms, synonyms, broader terms, narrower terms Build search statement / complete a search form in a database – boolean connectors, truncation, etc. 2

Isn’t Google Enough? Google search results: best on top Not all good information comes free on the Web Often, the best information source is available via paid databases. Most databases do not support Google or natural language. You will get zero hits! 3

Develop Your Topic Understand the context & issues involved, look for inspiration: – Check out an overview in general or subject encyclopedias. – Grab a handbook/textbook and check out the table of contents. – SmartCat Type “air pollution” Expand Subject on the right. 4

Test the Water Try these databases to see how much or how little is there: – Library catalog for books and media – ProQuest / Academic Search Premier for general HSS topics – Business Source Premier for business topics – LexisNexis Academic for news Pick up new ideas and refine your topic. 5

Refine your Topic Choose a focus or angle with a manageable scope. – Narrow a topic, eg.,"air pollution"  "air pollution in Hong Kong“ or “air pollution and respiratory diseases in Hong Kong” – Broaden a topic, eg., "acid rain impact on Lamma Island in Hong Kong"  "acid rain impact on the environment in Hong Kong” 6

Drugs: Find a Focus Drug use among teenagers – social, education Drug addicts and psychology Athletes and drug use – sports ethics Drug trafficking – social, political, legal Drugs laws – legal Drugs research & development for bird flu – medicine, pharmacology Your focus will affect choice of databases. 7

Truncation Means "make something shorter". Use a symbol to retrieve the various endings of words beginning with a common word root. Different databases use different symbols for truncation. The most common symbols are * and ?. Some use ! or $ signs. Not applicable to Chinese. 16

Truncation- examples 17 Econom* will retrieve Economy Economic Economics Economical Economist Economists Pollut* will retrieve Pollutes Polluted Polluting Pollution Pollutant Pollutants Use it to catch all relevant records.
