📚 Compact OpenAIRE Citation Graph Based on OpenAIRE Graph v11.1.1 (source on Zenodo).

Citation graphs at this scale are usually locked behind multi-terabyte dumps and heavyweight infrastructure.

📚 Compact OpenAIRE Citation Graph
<!-- BASED-ON:START --> Based on OpenAIRE Graph v11.1.1 ([source on Zenodo](https://zenodo.org/records/20428976)). <!-- BASED-ON:END -->
The complete OpenAIRE citation graph, distilled into a handful of compact, analysis-ready files — the full scholarly citation network of the open-science ecosystem, small enough to actually work with.
Citation graphs at this scale are usually locked behind multi-terabyte dumps and heavyweight infrastructure. This dataset makes the entire OpenAIRE citation network loadable on a normal machine: publications as nodes, citations as edges, served as compressed Parquet with a memory-efficient loading path. A richer node file adds titles, abstracts, authors, dates, and a full set of persistent identifiers (DOI, PubMed, MAG, arXiv, and more) for text-attributed and metadata-driven work.

Dataset structure
The dataset is a directed citation graph: publications are nodes, citations are edges.
Features/columns in publications_large
Quickstart
import pandas as pd
from huggingface_hub import hf_hub_download
REPO = "Zmeos/Compact_OpenAIRE_citation_graph"
# citations (edges)
cites = pd.read_parquet(
hf_hub_download(REPO, "citations.parquet", repo_type="dataset"),
engine="pyarrow", dtype_backend="pyarrow",
)
# publications_large (nodes + metadata) — may not fit in memory;
# select only the columns you need
large = pd.read_parquet(
hf_hub_download(REPO, "publications_large.parquet", repo_type="dataset"),
columns=["nodeId", "title", "pid_dois"],
engine="pyarrow", dtype_backend="pyarrow",
)Reproducibility
The PySpark pipeline used to produce these files (with a Singularity/Apptainer container for portability) is archived on Zenodo as pipeline.tar.xz and maintained at Codeberg.
