What is a Keyword?
Keywords are specific words which are found in the title and abstract. Keywords are also called textwords or natural language.
In this module, you will learn how to find relevant keywords, or natural language for our first, or P, element.
Remember, for each PICO element we will perform both a Subject Heading and a Keyword search. Each type of search has different advantages that will make our search more relevant.
Keywords are helpful when:
Be aware: In most databases the search engine is looking for a match of the keyword in the Title and Abstract, not the full text.
When using keywords or natural language we need to take into account:
Many of these can be addressed by using Wildcards. See: Using Wildcards below.
Now let's do the keyword search.
Consider again the research question: "What research has been done on the use of games such as Wii, Kinnect and others for improving balance in children and teenagers who have a traumatic brain injury including concussion."
In Step 2, we identified the subject headings Brain Concussion as well as Brain Injuries, Traumatic.
For each concept search we will perform a related keyword search in addition to the Subject Heading Search.
From the Used For list in the Scope Note for brain concussion and traumatic brain injury we noticed that related keywords for our subject headings are: Concussion and Brain Injury as well as their plural forms.
The adjacency, or proximity, operator is used to increase the relevancy and specificity of the keyword search
