Overview

The fetch_arxiv_citation_count function retrieves the citation count for a given arXiv paper from the Semantic Scholar Graph API, returning 0 on any failure.

Description

This function is defined in the repository's automation script and serves as the core data retrieval component of the Automated Citation Tracking pipeline. It constructs a request URL using the provided arXiv ID, queries the Semantic Scholar Graph API for the citationCount field, and returns the integer citation count. The function is designed for resilience: any exception -- network timeout, HTTP error, JSON parsing failure, or missing field -- is caught, logged as a warning, and results in a return value of 0 rather than a pipeline crash.

The function is called iteratively for each arXiv paper tracked by the repository. The individual citation counts are then summed to produce a total that is written into the badge JSON file.

Usage

This function is called within the update_arxiv_citations.py script during the CI workflow. It is invoked once per tracked arXiv paper ID. The script iterates over a list of known paper IDs, calls this function for each, and aggregates the results.

Inputs

Input Type Description Example
arxiv_id str The arXiv identifier of the paper (without the ARXIV: prefix) "2503.24235"

Outputs

Output Type Description Example
Citation count int The number of citations for the paper. Returns 0 if the paper is not found or if any error occurs. 42

Usage Examples

Example 1: Basic usage 

count = fetch_arxiv_citation_count("2503.24235")
print(f"Citations: {count}")
# Output: Citations: 42

Example 2: Handling a non-existent paper 

count = fetch_arxiv_citation_count("0000.00000")
# [Warning] Failed to fetch citation for ArXiv:0000.00000 - 404 Client Error: Not Found
print(f"Citations: {count}")
# Output: Citations: 0

Example 3: Aggregating citations for multiple papers 

arxiv_ids = ["2503.24235", "2501.12345", "2502.67890"]
total = sum(fetch_arxiv_citation_count(aid) for aid in arxiv_ids)
print(f"Total citations: {total}")
