Open Social Science Citation Index (OpenSSCI)

Description: 

The dataset OpenSSCI comprises reference metadata and citation links derived from 63,070 full-text academic documents archived in the SSOAR (Social Science Open Access Repository). The data has been curated within the OUTCITE project for downstream ingestion into OpenCitations. The main goal of OUTCITE is to research, develop, and deploy an open-source toolchain for linking literature references—including non-source items—to their sources. Demo system: <https://demo-outcite.gesis.org/>

Extracted and validated data in OpenSSCI (date: 26/11/2025):

Metadata: 2,306,779 (references after validation)

Citations: 3,126,779 (links citing–cited ID pairs)

Purpose:

Making bibliographic data available is important in all disciplines to ensure easy and fast access to the literature and other scientific resources such as research datasets. To this end, many publishers strive to index their publications in bibliographic databases enabling the linking of publications in a citation graph. Still, a significant part of citation data in disciplines such as social science is not accessible via bibliographic databases.

To provide validated reference metadata and citation links from SSOAR for ingestion into OpenCitations, enabling open, reproducible citation analysis and to support research in bibliometrics, IR, and open science by offering a reusable dataset.

Dataset Structure:

# 数据集描述
OpenSSCI数据集包含源自存档于SSOAR（Social Science Open Access Repository，社会科学开放获取知识库）的63070篇全文学术文献的参考文献元数据与引用链接。该数据集由OUTCITE项目整理，以供后续导入至OpenCitations平台。OUTCITE项目的核心目标是研发并部署一套开源工具链，用于将各类文献参考文献（包括非源文献条目）与其源文献建立关联。
演示系统：<https://demo-outcite.gesis.org/>

OpenSSCI数据集的提取与验证数据（日期：2025年11月26日）：
- 元数据：2,306,779条（验证后的参考文献条目）
- 引用链接：3,126,779条（引用方-被引用方ID对链接）

## 数据集用途
在所有学科领域中，开放书目数据均具有重要意义，可确保用户便捷快速地获取文献及研究数据集等其他科学资源。为此，众多出版商致力于将其出版物编入书目数据库，以实现文献在引用网络中的关联。但诸如社会科学等学科的大量引用数据仍无法通过书目数据库获取。
本数据集旨在提供源自SSOAR的经验证参考文献元数据与引用链接，以供导入至OpenCitations平台，从而支持可开放、可复现的引用分析，并通过提供可复用数据集，助力文献计量学、信息检索（Information Retrieval）及开放科学领域的研究。
