+# Dataset Card for heuristic_classification-filtered-pile-50M

+## Dataset Description

+- **Point of Contact: Sang Michael Xie <xie@cs.stanford.edu>** 
+
+### Dataset Summary
+
+This dataset is a subset of The Pile, selected via the heuristic classification data selection method. The target distribution for heuristic classification are the Wikipedia and BookCorpus2 subsets of The Pile.
+
+
+### Languages
+
+English (EN)
+
+## Dataset Structure
+
+A train set is provided (51.2M examples) in jsonl format.
+
+### Data Instances

+### Data Fields
+
+```
+"contents": the text
+"metadata": contains information about the source(s) of text that the text comes from. Multiple sources means that the example is concatenated from two sources.
+"id": Ignore - a non-unique identifier
+```
+
+## Dataset Creation
+We first select 102.4M examples then concatenate every two examples to create 51.2M examples.
+This ensures that the examples are long enough for a max token length of 512 without much padding.
+We train the fasttext binary classifier for heuristic classification from The Pile validation set, where the target is Wikipedia + BookCorpus2 + Gutenberg + Books3 and the raw data come from the rest of the data sources in The Pile.
+We first select 98.4M examples from non-Wikipedia and book data, then randomly select 2M from Wikipedia and 0.66M each from BookCorpus2, Gutenberg, and Books3. 
+After this, we concatenate every two examples.
+
+### Source Data
+The Pile
+
+#### Initial Data Collection and Normalization
+We select data from The Pile, which comes in 30 random chunks. We reserve chunk 0 for validation purposes and only consider the last 29 chunks.
+We first divided the documents in The Pile into chunks of 128 words, according to whitespace tokenization.
+These chunks define the examples that we do data selection on, totaling 1.7B examples.
+Before heuristic classification, we first apply a manual quality filter (see paper for details) and only consider the examples that pass the filter.
+
+
+## Considerations for Using the Data
+
+The dataset is biased towards choosing data from non-Wikipedia and non-Books sources. A balanced approach would be to mix in more data from Wikipedia and books.
