Facts, not a score: Melola does not rate authors or compute credit points. The summary counts only articles linked through OpenAlex; articles matched by name alone are listed separately and not counted. Melola covers Indonesian journals harvested through OAI-PMH, so publications elsewhere may be missing. How notices are checked.
