Sequence Labeling Dataset Route

Use this sub-skill when the user intent matches one of these signals:

• NER, named entity recognition, entity spans, BIO or BMEO labels
• Chinese medical or news entity extraction datasets
• CLUENER, CCKS, MSRA, Boson, CoNLL-2003, SIGHAN Bakeoff

Read references/dataset-selection.md for NER candidate comparison and references/troubleshooting.md for entity-task caveats.

Fast workflow

1. Restate the user's requested task, language, domain, and output need.
2. Search the bundled root index before recommending a row:

python ../../scripts/search_dataset_index.py --category ner --query cluener
python ../../scripts/search_dataset_index.py --category ner --query medical
python ../../scripts/search_dataset_index.py --category ner --language English

3. Compare title, category, description, keywords, provider, license, paper, and note fields.
4. Warn that CLUEDatasetSearch is a catalogue: no dataset files are bundled and external access must be verified.
5. If the request belongs to another family, route to the sibling sub-skill named below instead of forcing a weak match.

Boundary routes

• Root overview and cross-category search: ../../SKILL.md.
• Shared table schema and duplicate handling: ../../references/catalogue-overview.md.
• Access, license, privacy, and link caveats: ../../references/access-and-license-caveats.md.
• Full bundled index: ../../references/dataset-index.json.
• Cross-cutting troubleshooting: ../../references/troubleshooting.md.

Output pattern

When answering, include:

• candidate dataset title and category;
• why it fits the task;
• language/domain/scale hints from the catalogue;
• provider and source URL when present in the bundled index;
• license/access caveat, especially if blank or competition-hosted;
• what the user must verify upstream before download, redistribution, or benchmark use.

Do not tell future agents to open or run files from the original repository checkout.
