WAAI: A Weighted Author Afliation Index for Journal Evaluation

Journal evaluation methodologies are often used to produce journal-ranking lists for various purposes. In this study, the authors present a modularity-based journal evaluation methodology based on the proportional contributions that journals receive from authors affiliated with globally ranked institutions. This empirically developed methodology draws on a stratification of institutions in the global rankings to allocate weights to article batches in a given journal. The authors apply the proposed methodology to evaluating 12,150 scholarly journals in different subject fields. The results show an elitist set of journals with a heavy tendency to publish mostly from authors affiliated with the top-ranked institutions. These journals have the highest weighted author affiliation index (WAAI) scores and are highly distinguished titles in different subject fields. However, the authors find a large population of journals that receive contributions mostly from institutions at lower ranks. They argue that the WAAI methodology provides a generic and objective evaluation technique for ranking journals across all disciplines.
