# Dataset Card for Astro-HEP Corpus |
|
|
|
**Astro-HEP Corpus** consists of approximately 21.8 million paragraphs extracted from more than 600,000 scholarly articles related to astrophysics or high energy physics or both. All articles were published between 1986 and 2022 (inclusive) on the open-access archive <a target="_blank" rel="noopener noreferrer" href="http://arxiv.org/" >arXiv.org</a>. Note: Due to copyright uncertainties, I am unable to make the actual data available here. |

The primary purpose of the Astro-HEP Corpus, beyond its role as a training set for the for the <a target="_blank" rel="noopener noreferrer" href="https://huggingface.co/arnosimons/astro-hep-bert">Astro-HEP-BERT</a> model, lies in its use for analyzing the meaning of concepts in astrophysics and high energy physics. For further insights into the corpus, the model, and the underlying research project (<a target="_blank" rel="noopener noreferrer" href="https://doi.org/10.3030/101044932" >Network Epistemology in Practice</a>) please refer to this paper [link coming soon]. |

## Composition |
|
|
|
This figure shows the temporal distribution of articles in terms of initial publication year, category (ASTRO or HEP), and subcategory (six subcategories for |
|
ASTRO and four subcategories for HEP), all of which is metadata directly imported from arXiv.org: |

## Construction |
|
|
|
<!-- The articles were selected using the <a target="_blank" rel="noopener noreferrer" href="https://www.kaggle.com/datasets/Cornell-University/arxiv" >original arXiv metadata file</a> and the <a target="_blank" rel="noopener noreferrer" href="https://arxiv.org/category_taxonomy" >original arXiv taxonomy</a>, which comprises four primary categories for high energy physics (hep-ex, hep-lat, hep-ph, and hep-th) and one primary category for astrophysics (astro-ph). The latter includes six subcategories (astro-ph.CO, astro-ph.EP, astro-ph.GA, astro-ph.HE, astro-ph.IM, and astro-ph.SR). <a target="_blank" rel="noopener noreferrer" href="https://www.pandoc.org/" >Pandoc</a> was used to extract plain text from the original latex files sourced from arXiv.org. In addition, all in-text citations were replaced with the marker "[CIT]" and all multiline mathematical expressions were replaced with with "FORMULA". Mathematical expressions in the inline math mode (e.g. "$...$") remained unaltered. To parse the plain text versions of the articles into their respective paragraphs, no specialized parser was necessary because, owing to the requirements of the LaTeX markup language and the parsing already performed by Pandoc, all paragraphs could be parsed by straightforward newline splitting. Additional cleaning was performed to remove authorship and funding information as well as noisy paragraphs (see here [link coming soon]). --> |
