Frequently asked questions

Clarify preview scope, scale and permissions before delivery.

Does the kit contain the full dataset?

10 preview records · 2 image excerpts · dictionary and README. The public kit is for preview evaluation. Full data requires a confirmed version and delivery list.

Why does catalog scale differ from preview count?

Catalog scale comes from registered sources or official specifications. Public kits contain limited excerpts or references. Verify actual deliverable scale for your selected scope.

Can I use it for training or commercial projects?

Confirm the selected version’s license, provenance and permitted uses. Catalog listing and preview access do not grant training, commercial-use or redistribution rights to the full data.

Evaluation and acceptance checks

Check the actual samples before selecting a batch. These are suggested acceptance criteria, not quality guarantees for the full corpus.

01

Separate journal aggregates from paper records

Ask for verifiable examples or counting rules for your selected version and use.

02

Journal names, year ranges and counting rules

Ask for verifiable examples or counting rules for your selected version and use.

03

Verify article IDs, format and rights for any full text

Ask for verifiable examples or counting rules for your selected version and use.

Find the right scope for your project
