# Noun Phrases Dataset |
|
|
|
This dataset contains noun phrases extracted from [allenai/c4](https://huggingface.co/datasets/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 |
|
```json |
|
{"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:**](https://textacy.readthedocs.io/en/latest/api_reference/preprocessing.html) Unicode normalization, bracket removal, bullet point standardization, quotation mark normalization, and whitespace normalization. |
|
- [**SpaCy:**](https://spacy.io/) Noun phrase extraction using the `"en_core_web_sm"` model. Articles such as "a" or "the" were removed. |
|
|
|
