Bibliometrics

Bibliometrics is the quantitative analysis of published research literature, including citation patterns, authorship networks, keyword frequencies, and publication trends. In accessibility research, bibliometric methods help identify research gaps, map the evolution of topics over time, and reveal connections between different research communities. Common techniques include document bibliographic coupling (grouping papers by shared references), co-citation analysis, and keyword co-occurrence mapping. Tools like VOSviewer and bibliometrix support this analysis, enabling researchers to synthesize large bodies of literature systematically.
