+# 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:** 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
+
+Suitable for grammar analysis, linguistic studies, and natural language processing (NLP) tasks.
