| description | Extract named entities (persons, organizations, dates, locations) from text and provide them in structured JSON-LD format. |
The NLP Expert skill uses Gemini 3 to perform advanced Named Entity Recognition (NER). It identifies key entities within dataset descriptions, transcripts, or web results and maps them to standard Schema.org types in JSON-LD.
This is critical for establishing provenance, identifying dataset creators, and mapping geographic and temporal coverage in the Croissant specification.
Analyzes text or a file and returns all detected entities as JSON-LD. Results are stored in ./data/nlp/.
Usage:
# Process raw text
python3 nlp_expert/scripts/extract_entities.py "Sergei Bodrov was born in Moscow in 1971."
# Process a file (e.g., a transcript)
python3 nlp_expert/scripts/extract_entities.py data/transcripts/6cWcZ2G53gE.txt
