This document discusses identifying research gaps through literature review. It defines a research gap as a topic or area that has not been fully explored, limiting researchers' ability to answer a question. Common challenges in identifying gaps include getting overwhelmed by information, difficulty organizing findings, and hesitating to question established ideas. The document recommends systematically analyzing gaps by identifying a broad research area, thoroughly researching the gap's viability with an expected outcome, and using an evidence-based scientific method. Overall, the key to identifying gaps is asking ontological, epistemological, and methodological questions about existing literature.
