[2.2] Identifying and Defining Research Gaps

• RESEARCH GAP


  The primary basis in the investigation of any problem, phenomenon, or scientific question.
• KNOWLEDGE GAP


  This is the overall lack of information on a topic or specific issue.
• THEORETICAL GAP


  This occurs when there is a missing or underdeveloped theoretical framework to explain a phenomenon.
• METHODOLOGICAL GAP


  A variation of research methods is necessary to generate new insights or to avoid distorted findings.
• EMPIRICAL GAP


  This gap indicates the need for more empirical data (i.e., observable and measurable evidence) on a topic.
• EVIDENCE GAP


  Results from studies allow for conclusions but are contradictory when examined from an abstract point of view.
• POPULATION GAP


  This gap emerges when a specific population (e.g., age group, ethnicity, socioeconomic group) is underrepresented in the research.
• LITERATURE MINING


  a method used to extract information from scientific literature
• SYSTEMATIC REVIEW


  Type of research study that collects, critically analyzes, and synthesizes all available evidence on a specific research question or topic.
• RECENT WORKS


  Studies, research papers, or scholarly articles that have been published within the last 5 to 10 years reflect the latest evidence or advancements in their field.
• SEMINAL WORKS


  Foundational pieces of research that introduce new concepts, theories, or methodologies, and significantly advance understanding in a particular field.
• CHART METHOD OR CONCEPT MATRIX


  Methods of identifying research gaps according to predetermined categories (variables examined, level of analysis, theoretical issues, scope & limitations)
