+# 🌐 Essential-Web: Complete 24-Trillion Token Dataset (Upload in-progress...)
+
+[🏆 Website](https://www.essential.ai/)  |  [🖥️ Code](https://github.com/Essential-AI/eai-taxonomy)  |  [📖 Paper](https://huggingface.co/papers/2506.14111)
+
+## 📋 Dataset Description
+
+Essential-Web is a 24-trillion-token web dataset with document-level metadata designed for flexible dataset curation. The dataset provides metadata including subject matter classification, web page type, content complexity, and document quality scores for each of the 23.6 billion documents.
+
+Researchers can filter and curate specialized datasets using the provided metadata, reducing the need for custom preprocessing pipelines and domain-specific classifiers.
+
+## 🔍 Free Decimal Correspondence (FDC) Taxonomy
+
+Essential-Web uses the Free Decimal Correspondence, a Dewey Decimal-inspired open taxonomy with 12 main categories for classifying web content. This systematic approach enables precise domain filtering and dataset curation.
+
+For help navigating FDC codes, see: https://www.librarything.com/mds
+
+## ⚙️ Dataset Creation
+
+Essential-Web was created using a comprehensive processing pipeline starting from Common Crawl data:
+
+### 📥 Source Data
+- **DCLM Pool**: 89 resiliparse-extracted Common Crawl WARC snapshots (CC-MAIN-2013-20 to CC-MAIN-2022-49)
+- **Additional Snapshots**: 12 additional snapshots extracted from CC-MAIN-2023-06 to CC-MAIN-2024-38 using resiliparse
+- **Total**: 101 Common Crawl snapshots processed
+
+### 🔧 Processing Pipeline
+1. **Document ID Generation**: Using xxhash.xxh3_64_intdigest for unique document identification
+2. **Global Deduplication**: Hash-based deduplication across all 101 snapshots
+3. **Minhash LSH Deduplication**: Snapshot-level deduplication with Jaccard threshold of 0.7 (14 bands, 9 rows per band)
+4. **Quality Annotation**: Statistical and model-based quality signals using RedPajama-Data-V2 pipeline variant, including DCLM-baseline fastText classifier
+5. **Quality Filtering**: Manual tuned filters to retain high-quality English documents while preserving math and code content
+6. **Taxonomy Labeling**: Classification of every document using EAI-Taxonomy-0.5b (~90,000 AMD MI300x GPU-hours)
+
+## 🎯 Performance & Validation
+
+We've curated example domain-specific datasets from Essential-Web using simple metadata filters, showing competitive performance relative to top performing web-curated datasets:
+
+- 🧮 **Math**: within 8.0% of web-curated baselines
+- 💻 **Web Code**: 14.3% above web-curated baselines  
+- 🔬 **STEM**: 24.5% above web-curated baselines
+- 🩺 **Medical**: 8.6% above web-curated baselines
+
+*Note: These represent initial examples with significant room for further curation and improvement. Comparisons are against web-sourced datasets rather than specialized synthetic datasets.*

+## 🎯 Intended Use
+
+Essential-Web enables researchers to:
+- 🚀 **Rapid Curation**: Create multi-billion-token domain-specific datasets in minutes using SQL-like filters
+- 🔍 **Flexible Exploration**: Explore web content across subjects, quality levels, and content types
+- 🏗️ **Custom Pipelines**: Build specialized training corpora without custom classification infrastructure
+- 🔄 **Iterative Improvement**: Easily modify and refine dataset composition based on training results
+- 📊 **Quality Control**: Filter out low-quality content (ads, product listings) while preserving reasoning-dense documents

+# Dataset Schema Documentation
+
+## Overview
+
+This dataset contains web-crawled text data with comprehensive metadata, quality signals, and taxonomic classifications. Each record represents a document extracted from web archives with detailed provenance tracking and quality assessment metrics.
+
+## Core Fields
+
+| Field | Type | Description | Path |
+|-------|------|-------------|------|
+| `id` | `Int64` | Unique identifier based on document hash | `id` |
+| `text` | `String` | The main textual content of the document | `text` |
+
+## EAI Taxonomy Classification
+
+Comprehensive hierarchical classification system with primary and secondary labels - the most important feature of this dataset. The taxonomy is designed to provide detailed subject categorization, document type identification, content quality assessment, and extraction quality indicators.
+
+<details>
+<summary><strong>Free Decimal Correspondence (FDC)</strong></summary>
+
+A Dewey Decimal-inspired classification system with 3-level hierarchical labels. The FDC provides nested categories where each successive level refines its parent category. It's designed to be compatible with the Dewey Decimal System for library cataloging.
+
+**Level Structure:**
+- **Level 1**: Top-level categories (0-9) covering broad subject areas like General works, Philosophy, Religion, Social Sciences, etc.
+- **Level 2**: Sub-divisions (00-99) that refine Level 1 categories
+- **Level 3**: Specific categories (000-999) that further refine Level 2 categories

+## How to Load the Dataset
+
+This section provides examples of how to load the `EssentialAI/essential-web-v1.0` dataset using different Python libraries and frameworks.
+
+### Using Hugging Face Datasets (Standard Method)
+
+The simplest way to load the dataset is using the Hugging Face `datasets` library:
+
+```python
+from datasets import load_dataset
+
+# Load the entire dataset
+dataset = load_dataset("EssentialAI/essential-web-v1.0")
+
+# View dataset structure
+print(dataset)
+print(f"Number of examples: {len(dataset['train'])}")
+```
+
+You can also load the dataset in streaming mode to avoid downloading the entire dataset at once:
+
+```python
+from datasets import load_dataset
+
+# Load in streaming mode
+dataset = load_dataset("EssentialAI/essential-web-v1.0", streaming=True)
+data_stream = dataset["train"]
+
+# Iterate through examples
+for example in data_stream.take(5):
+    print(example)
+```
+
+### Using PySpark
+
+For large-scale distributed processing, you can load the dataset using PySpark with the `pyspark_huggingface` library:
+
+```python
+# First install the required library:
+# pip install pyspark_huggingface
+
+import pyspark_huggingface
+from pyspark.sql import SparkSession
+
+# Initialize Spark session
+spark = SparkSession.builder.appName("EAI-Taxonomy-Web").getOrCreate()
+
+# Load the dataset using the "huggingface" data source
+df = spark.read.format("huggingface").load("EssentialAI/essential-web-v1.0")
+
+# Basic dataset exploration
+print(f"Dataset shape: {df.count()} rows, {len(df.columns)} columns")
+df.show(10)
+df.printSchema()
+
+# Load only specific columns for efficiency
+df_subset = (
+    spark.read.format("huggingface")
+    .option("columns", '["column1", "column2"]')  # Replace with actual column names
+    .load("EssentialAI/essential-web-v1.0")
+)
+
+# Run SQL queries on the dataset
+df.createOrReplaceTempView("eai_web_dataset")
+result = spark.sql("""
+    SELECT COUNT(*) as total_examples
+    FROM eai_web_dataset
+""")
+result.show()
+```
+
+### Using Daft
+
+Daft provides a modern DataFrame library optimized for machine learning workloads. You can load the dataset directly from Hugging Face:
+
+```python
+import daft
+
+# Load the entire dataset
+df = daft.read_parquet("hf://datasets/EssentialAI/essential-web-v1.0")
+
+# Basic exploration
+print("Dataset schema:")
+df.schema()
+
+print("First 5 rows:")
+df.show(5)
+```
+
+If you need to access private datasets or use authentication:
+
+```python
+import daft
+from daft.io import IOConfig, HTTPConfig
+
+io_config = IOConfig(http=HTTPConfig(bearer_token="your_token"))
+df = daft.read_parquet("hf://datasets/EssentialAI/essential-web-v1.0", io_config=io_config)
+```
+
+### Installation Requirements
+
+Make sure you have the required libraries installed:
+
+```bash
+# For Hugging Face datasets
+pip install datasets
+
+# For PySpark with Hugging Face integration
+pip install pyspark_huggingface
+
+# For Daft
+pip install daft
+```
