Dataset Description

Dataset Summary

This dataset is one of the two datasets published by "Honey, I Shrunk the Language: Language Model Behavior at Reduced Scale" (https://arxiv.org/abs/2305.17266). The dataset available at this link is the pre-training data constrained by vocabulary. The other published data i.e. the pre-training data that is not constrained by vocabulary is available at https://huggingface.co/datasets/text-machine-lab/unconstrained_language.

The vocabulary used for curating the data is constructed from the AOChildes corpus (https://www.sciencedirect.com/science/article/abs/pii/S0079742121000256). The AOChildes corpus consists of transcripts of child-directed speech. Hence, the vocabulary constructed from AOChildes corpus consists of words spoken or heard by children of age six years or younger.

The vocabulary is then used to filter the widely used text corpora,

From the above corpora, only those spans are included that contain words only from the predefined vocabulary. The dataset includes 44 million sentences (~6 million sequences, each with ~128 tokens) and 3 million contiguous spans (each with ~128 tokens). Refer to Table 1 of the paper for data distribution over different corpora.

Languages

The dataset contains the English language only.

Dataset Structure

The dataset is available in the arrow dataset format with three splits namely, train, validation, and test. Every data instance has only one key "Text" that included a text span of approximately 128 tokens.
