oasnap-reader
Read a full OpenAlex snapshot and convert it to a reduced dataset for analysis.
The reduced dataset filters out paratext records and extracts bibliographic fields, topic classifications, authorship, and citation data into a compact format suitable for large-scale analysis.
Full conversion time depends on available hardware. The full conversion with >2000 files took ~2 hours with 24 workers and sufficient RAM.
Install
pip install oasnap-reader
Usage
from pathlib import Path
from oasnap_reader.reader import ReadGZ
reader = ReadGZ(
in_path=Path("/data/openalex/works"),
out_path=Path("/data/reduced"),
)
reader.read_all()
in_path should point to the root of the OpenAlex works snapshot directory.
Output is one gzip-compressed JSONL file per input file, written to out_path.
