Noun Phrases Dataset

This dataset contains noun phrases extracted from allenai/c4.

It includes two configurations: uncased and cased, with 1 895 908 and 2 000 002 entries, respectively.

JSONL Fields

Each entry contains:

noun_phrase: The extracted noun phrase.
count: Frequency of occurrence.

Example Rows

{"noun_phrase": "ship invoices", "count": 1}
{"noun_phrase": "\"river", "count": 1}
{"noun_phrase": "no boiler system", "count": 1}

Construction

Cased Data: Original noun phrases with preserved casing.
Uncased Data: Constructed by normalizing cased data to lowercase, aggregating counts for identical phrases, and retaining the original phrase with the highest count.

Preprocessing and Extraction

Preprocessing: Unicode normalization, bracket removal, bullet point standardization, quotation mark normalization, and whitespace normalization.
SpaCy: Noun phrase extraction using the "en_core_web_sm" model. Articles such as "a" or "the" were removed.

Original Data Source

The C4 dataset is a cleaned version of the Common Crawl dataset, providing a comprehensive source of English text for linguistic analysis and NLP tasks.

Applications
