Data Vetting & Methodology
At JournalsHub, we recognize that academic publishing decisions are high-stakes. To ensure our users have the most accurate information, we employ a multi-layered verification process for every journal in our database.
1. Primary Data Sources
Our database is built upon the aggregation of several authoritative, public-domain academic repositories. We do not "scrape" unofficial websites; instead, we pull structured data weekly from:
- OpenAlex: A massive open-source index of the global research system.
- DOAJ: The Directory of Open Access Journals, used to verify legitimate Open Access status.
- Crossref: Used for DOI and metadata consistency checks.
2. Impact Factor Verification
Impact factors are one of the most searched academic metrics. We categorize our metrics into two tiers:
- JCR (Journal Citation Reports): Impact factors sourced from official Clarivate analytics.
- OpenAlex Verified: 2-year mean citedness scores used as a real-time proxy for journals not yet tracked by Clarivate.
3. The JournalsHub 'Risk Alert' System
To protect researchers from predatory journals, we have implemented an automated monitoring system. If a journal's impact factor drops by more than 20% over a 2-year period, or if its indexing status in DOAJ changes, our system automatically flags the journal for manual review. This captures the high-anxiety search intent of researchers checking for "Scopus removed journals."
4. Integrity & Transparency
JournalsHub.online is an independent data aggregator. We are not affiliated with any specific publisher. This independence allows us to provide unbiased comparisons of APC fees and review speeds across competing titles like Elsevier, Springer, and Wiley.
