Knowledge gaps refer to areas within a particular field of research where there is limited information, understanding, or consensus. These gaps can be identified through literature reviews, empirical studies, and expert opinions. They indicate areas where further research is needed to fill in missing pieces of knowledge or to address unanswered questions. Research in knowledge gaps involves identifying, categorizing, and prioritizing the gaps in existing knowledge within a specific field or subfield. This process helps researchers and policymakers determine where to focus their efforts and resources to advance the understanding of a topic or issue. By identifying and addressing knowledge gaps, researchers can contribute new insights, theories, and evidence to the existing body of knowledge. This can lead to advancements in scientific understanding, technology development, policy formulation, and practical solutions to complex problems.
