Q: What does addressing a gap in knowledge mean?

Detailed Question -

When stating a problem in research, how can one really understand the area that is a gap in a given sphere of knowledge before conducting research to bridge the gap?

1 Answer to this question
Answer:

As you have rightly noted, research is conducted to bridge or address a gap in knowledge. However, to understand or identify a gap in knowledge, you need to do a literature search, which is done before conducting the research. In the course of a literature search, you first identify and then go through literature related to your topic. This may include previous studies, theoretical papers (that discuss only the conceptual aspects of a solution), and expert articles. In the case of a literature review paper, this may also include unpublished literature (also called grey literature). A thorough literature search typically reveals gaps in existing knowledge in the field. You may decide to address one, some, or all of these gaps in your research.
