+# High Quality Text Dataset
+
+A curated collection of English-language texts for AI training and research.
+
+### Sources
+- [HuggingFaceFW/fineweb-edu](https://huggingface.co/datasets/HuggingFaceFW/fineweb-edu)  
+- [openbmb/Ultra-FineWeb](https://huggingface.co/datasets/openbmb/Ultra-FineWeb)  
+- [Zyphra/Zyda-2](https://huggingface.co/datasets/Zyphra/Zyda-2)  
+
+Each dataset was
+1. Split into ~2 000-token chunks using the [LLaMA 3.1 tokenizer](https://huggingface.co/meta-llama/Llama-3.1-8B-Instruct)
+2. Cleaned (normalized spaces, punctuation, and characters, replaced emails and phone numbers with placeholders)
+3. Scored using the [`agentlans/GIST-all-MiniLM-L6-v2-quality-v3`](https://huggingface.co/agentlans/GIST-all-MiniLM-L6-v2-quality-v3) classifier
+4. Exact duplicates removed
+
+100 000 chunks per source were included.
+
+### Clustering
+Agglomerative clustering was applied using embeddings from the [`Snowflake/snowflake-arctic-embed-xs`](https://huggingface.co/Snowflake/snowflake-arctic-embed-xs) 
+model at multiple cluster counts: 100, 200, 500, 1 000, 2 000, 5 000, 10 000, 20 000, 50 000, 100 000, and 200 000 clusters, enabling flexible dataset configurations.
+
+### Example Entry
+
+```json
+{
+  "text": "Dr. Louise Glew has been appointed the Global Lead Scientist for WWF's Global Science Team. Louise's research focuses on understanding the social and ecological impacts of conservation interventions [...]",
+  "quality": 2.0699,
+  "source": "openbmb/Ultra-FineWeb"
+}
+```
+
+### Limitations
+- Focused on academic, educational, and pedagogical content for a general audience.  
+- May contain outdated or unreliable information (including self-published material, pseudoscience, conspiracy theories).  
+- Quality scores reflect syntax and tone, not factual accuracy.  
+- Some repetition may occur (for example, dictionary entries, geographic distance calculations).
+- The entries may be broken in the middle of a word or sentence.
