Before we start to write or conduct a research, in this case PhD research, one should write a literature review.
Before we do the actual writing, first we search for any previous researches or papers. To do this we must choose the database that we are going to use. You can use Google Scholar or in this case we use Scopus. The main tools for us is keyword filtering.
In this case we use:
- tools: filter
- field: title and abstract
- results: number of publication
This pic shows results of keyword or string filtering in Scopus (as off 23 Oct 2014). I will elaborate more on this.
