Research area measures are tools or indicators used to quantify and evaluate the impact, productivity, and visibility of research within a specific field or discipline. These measures help researchers and institutions assess the quality and significance of research outputs, such as publications, patents, and citations. Some common research area measures include citation counts, h-index, journal impact factor, and altmetrics. These measures are used by researchers, funders, and institutions to gauge the influence of research and make informed decisions about funding, collaborations, and career advancement.
