# Dataset Card for Statistical Uncertainty in Word Embeddings: GloVe-V

<!-- Provide a quick summary of the dataset. -->

This is the data repository for the paper "Statistical Uncertainty in Word Embeddings: GloVe-V". 
Our preprint is available [here](https://arxiv.org/abs/2406.12165).

**We introduce a method to obtain approximate, easy-to-use, and scalable uncertainty estimates for the GloVe word embeddings and 
demonstrate its usefulness in natural language tasks and computational social science analysis.**

## Dataset Details

This data repository contains pre-computed GloVe embeddings and GloVe-V variances for several corpora, including:

- **Toy Corpus (300-dim)**: a subset of 11 words from the Corpus of Historical American English (1900-1999). Downloadable as `Toy-Embeddings`
- **Corpus of Historical American English (COHA) (1900-1999) (300-dim)**: Downloadable as `COHA_1900-1999_300d`
- More to come!

### Dataset Description

<!-- Provide a longer summary of what this dataset is. -->

This dataset contains pre-computed GloVe embeddings and GloVe-V variances for the corpora listed above. 

Given a vocabulary of size $V$, the GloVe-V variances require storing $V \times (D x D)$ floating point numbers.
For this reason, we produce two versions of the variances:

1. **Approximation Variances**: These are approximations to the full GloVe-V variances that can use either a diagonal approximation to the full variance, or a low-rank Singular Value Decomposition (SVD) approximation. We optimize this approximation at the level of each word to guarantee at least 90% reconstruction of the original variance. These approximations require storing much fewer floating point numbers than the full variances.
2. **Complete Variances**: These are the full GloVe-V variances, which require storing $V \times (D x D)$ floating point numbers. For example, in the case of the 300-dimensional embeddings for the COHA (1900-1999) corpus, this would be approximately 6.4 billion floating point numbers!

## Dataset Structure

<!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->

The dataset for each corpus contains the following files (see the **Storage of GloVe-V Variances** section below for more details on the differences between the complete and approximated variances):
- `vocab.txt`: a list of the words in the corpus with associated frequencies
- `vectors.safetensors`: a safetensors file containing the embeddings for each word in the corpus
- `complete_chunk_{i}.safetensors`: a set of safetensors file containing the complete variances for each word in the corpus. These variances are size $D \times D$, where $D$ is the embedding dimensionality, and thus are very storage-intensive.
- `approx_info.txt`: a text file containing information on the approximation used to approximate the full variance of each word (diagonal approximation, or SVD approximation)
- `ApproximationVariances.safetensors`: a safetensors file containing the approximation variances for each word in the corpus. These approximations require storing much fewer floating point numbers than the full variances. If a word has been approximated by a diagonal approximation, then this file will contain only $D$ floating point numbers for each word. Alternatively, if a word has been approximated by an SVD approximation of rank $k$, then this file will contain $k(2D + 1)$ floating point numbers for each word.
