+# SEA-PILE v2
+
+SEA-PILE v2 is a large, multilingual language modelling dataset of 120 billion tokens, sourced from a diverse array of web content.
+
+**Languages supported:** Vietnamese, Bahasa Indonesia, Tamil, Malay, Thai, Tagalog, Khmer, Lao, Burmese
+
+## Summary Statistics
+
+The total number of tokens in the dataset has been calculated using the Gemma3 tokenizer
+| **Language** | **ISO 639-1 Code** | **Total Number of Tokens (Billions)** | **Percentage** |
+|--|:--:|:--:|:--:|
+| Vietnamese | vi | 51.4 | 42.13% |
+| Bahasa Indonesia | id | 41.9 | 34.34% |
+| Tamil | ta | 9.3 | 7.62% |
+| Malay | ms | 9.3 | 7.62% |
+| Thai | th | 6.5 | 5.33% |
+| Tagalog | tl | 2.2 | 1.80% |
+| Khmer | km | 0.6 | 0.49% |
+| Lao | lo | 0.6 | 0.49% |
+| Burmese | my | 0.2 | 0.16% |
+
+`Please note that we are currently releasing only a portion of the dataset, with plans for future expansions.  These expansions will primarily involve adding more tokens for our Southeast Asian languages and incorporating additional languages, including Javanese and Sundanese.`
+
+## Data Pipeline
+
+This dataset was created by extracting text from 24 CommonCrawl snapshots, ranging from CC-MAIN-2020-45 to CC-MAIN-2024-18. To ensure uniqueness, we implemented a deduplication process within each snapshot, following the strategy outlined by CCNet. Additionally, we also applied heuristic quality filters and perplexity scoring, drawing on methodologies from Sailor and RedPajamav2. These techniques were developed in collaboration with native speakers to ensure cultural nuances are accurately captured.
+
+## Download
+
+To load this data using HuggingFace's `datasets` library, you can use the following code:
+```python
+from datasets import load_dataset
+
+seapilev2 = load_dataset("aisingapore/sea-pile-v2", "<ISO-639-1 code>")
+```
+For example, if you would like to download the Vietnamese data, you can specify the ISO 639-1 code (`vi`) as shown below:
+```python
+from datasets import load_dataset
+
+seapilev2_vi = load_dataset("aisingapore/sea-pile-v2", "vi")
+```
+If you wish to download all available datasets at once, you can use the following approach:
+```python
+languages = ['vi', 'id', 'ta', 'ms', 'th', 'tl', 'km', 'lo', 'my']
+
+seapilev2 = {}
+for language in languages:
+    seapilev2[language] = load_dataset('aisingapore/sea-pile-v2', language)
+```
+
+
+## Limitations
+
+Despite our best efforts to filter out undesirable (i.e NSFW, toxic and biased) content and personally identifiable information (PII), there is a possibility that some documents containing harmful, toxic, or private content may still pass through our pipeline. We are committed to continuously improving our filtering processes to minimize these occurrences.
