Data Sources for Ono.Jepang.org
Ono.Jepang.org is built from filtered open data, prepared site data, and editorial explanations for learners. This page explains what comes from lexical sources, what is written by Ono.Jepang.org, and where the claim limits are.
1. JMdict on-mim
JMdict from the Electronic Dictionary Research and Development Group is the main lexical source for Japanese entries on Ono.Jepang.org. The Ono.Jepang.org corpus is limited to entries marked on-mim, a broad marker for onomatopoeia and mimetic words.
Forms, readings, parts of speech, and basic meanings come from that source. They are reorganized into learner-facing pages instead of being shown as unedited dictionary data.
2. Prebuilt Site Data
Heavy data such as entries, search indexes, category lists, type lists, and navigation maps is processed before the site is published. When you open a page or search, the site reads prepared static data instead of scanning the full corpus from scratch.
This keeps the site fast and suitable for lightweight infrastructure. Data updates go through curation and site preparation before being published as new site data.
3. Ono.Jepang.org Editorial Layer
Local definitions, semantic categories, search keywords, usage notes, comparison words, and onomatopoeia type labels are Ono.Jepang.org editorial explanations.
Giongo, giseigo, gitaigo, giyougo, and gijougo are learning labels for function. They are not etymology claims, source-language claims, or detailed labels supplied directly by JMdict.
4. Examples and Learning Aids
Examples, when available, are learning material for simple context. Ono.Jepang.org examples are created and reviewed editorially; they should not be read as corpus quotations or proof that an expression is the most common in every context.
Readings, romanization, translations, small notes, and browser audio features are learning aids. Corrections can be sent through the Corrections page.
5. Attribution and Claim Limits
Attribution helps readers distinguish base lexical data from Ono.Jepang.org explanations. A source name does not mean every explanation on the page comes directly from that source.
Ono.Jepang.org does not make source-language, etymology, or corpus-attestation claims when the available data does not support them. For academic or professional decisions, verify with appropriate dictionaries and reference sources.
