Basics of Information Retrieval: From topic to search terms

Plan ahead what you are doing

Information retrieval begins with defining the research topic or problem.  As an information seeker, you will have to clarify to yourself what information you are looking for and where you may be able to find it. When planning your information retrieval, the following research questions may help you define your topic:

  • What is the topic you need information on?
  • What do you need the information for?
  • Is the information you need generic or scientific?
  • How much do you have time and resources?
  • What do you already know about the topic?
  • What is your angle of approach to the topic?
  • How old should the information be?
  • What language do you need the information in?

After piecing together your topic, consider concepts, terms and words which describe it. Remember the alternatives (synonyms, abbreviations).

Mind map

Mind maps etc. offer ways of specifying and outlining the research problem. A mind map is a tree-like figure where the topic is divided into sections and further into their subsections.
