| # Robin186/ISL |
|
|
| Public, provenance-first vocabulary index for Indian Sign Language. The 2026-07-17 |
| snapshot combines the public ISLRTC A-Z dictionary index with a small local INCLUDE |
| metadata snapshot, a validated motion catalog, and narrowly filtered SignSaarthi |
| lexicon annotations. It does not |
| download or contain dictionary videos, raw video corpora, audio, or signer media. |
|
|
| ## Coverage |
|
|
| | Measure | Count | |
| | --- | ---: | |
| | Dataset records | 12434 | |
| | Official ISLRTC entries preserved | 15560 | |
| | Canonical official terms | 12357 | |
| | Official duplicate-term groups consolidated | 2979 | |
| | INCLUDE vocabulary labels | 263 | |
| | Records with INCLUDE motion metadata | 262 | |
| | INCLUDE labels quarantined from motion playback | 1 | |
| | Official terms with INCLUDE motion metadata | 186 | |
| | Locally enriched admitted records | 12434 | |
|
|
| Repeated official terms are one dataset row with every distinct official entry ID and |
| detail URL retained under `official.entries`; they are not silently discarded. |
|
|
| ## Record fields |
|
|
| - `id`, `term`, `normalizedTerm`, `language`: stable vocabulary identity. |
| - `datasetIds`, `sourceUrls`, `official`, `include`: primary provenance, official |
| variants, source-split presence, and honest motion availability. |
| - `motion`: compact INCLUDE catalog metadata. The source catalog contains no landmark |
| frame arrays, so `framePayloadIncluded` is always `false` in this bundle. |
| - `lexicon`: safe local annotations only after the term independently matches ISLRTC |
| or INCLUDE. Aliases, token weights, source fields, and timestamps are not copied. |
| - `license`, `review`: per-row rights and expert-review status without certification claims. |
|
|
| ## Licensing and review |
|
|
| This dataset card uses `license: other` because it combines source-specific terms. |
| The official ISLRTC FAQ permits dictionary use for research, teaching, and technology |
| only when the data are not resold or used for profiteering and ISLRTC is properly |
| acknowledged. INCLUDE is tracked as CC-BY-4.0 based on its source metadata. This public |
| bundle contains metadata and source links only; it does not grant commercial rights or |
| permission to redistribute source media or derived landmark payloads. |
|
|
| The upstream INCLUDE metadata contains exact media-path overlap between its published |
| splits, so those split names are retained for provenance only and are not represented |
| as a leakage-safe evaluation benchmark. A label with no source-consistent training |
| path is kept as vocabulary but quarantined from motion playback. |
|
|
| An official dictionary listing establishes vocabulary provenance; it does not prove |
| that this merge or an INCLUDE motion clip received independent ISL expert review. |
| Motion review status is copied literally from the catalog and is currently represented |
| per record. |
|
|
| ## iSign exclusion |
|
|
| No iSign-only record or gated CSV content is included. The blended local lexicon may |
| enrich a term only after that term is independently admitted by ISLRTC or an INCLUDE |
| motion. Unmatched local terms are counted only in `metadata.json`; their text is not |
| written. The validator rejects iSign dataset provenance and gated local source paths. |
|
|
| ## Files |
|
|
| - `data/isl.jsonl`: deterministic records sorted by normalized term. |
| - `metadata.json`: input/page hashes, coverage, exclusions, licenses, and validation. |
| - `README.md`: this Hugging Face dataset card. |
|
|
| The bundle is intended for vocabulary lookup, coverage analysis, and motion |
| catalog joins. It is not a complete motion corpus, translation benchmark, or substitute |
| for review by qualified ISL users and experts. |
