Semantic Scholar
Semantic Scholar is a free, AI-powered search engine for academic literature, developed by the Allen Institute for AI to identify influential citations and connections.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
AI-Driven Citation Analysis
Unlike legacy databases that only count total citations, Semantic Scholar analyses the context of each citation. It uses machine learning to identify highly influential citations, which are instances where the citing author builds directly on the referenced paper's methodology or results. This allows researchers to distinguish between passing references and genuine intellectual lineage, saving time when mapping literature. The platform categorises citations by their intent, showing whether a paper is cited for background information, methodology comparison, or result discussion. This context-aware approach helps academics identify which publications have truly shaped subsequent research in their field. By filtering out superficial citations, scholars can focus their reviews on the most impactful articles, improving the overall quality and rigour of their literature synthesis.
Semantic Reader and Key Extractions
The platform features the Semantic Reader, an enhanced PDF reader designed to make reading scientific papers more efficient. It highlights inline citations, definitions, and mathematical symbols, providing pop-up previews so readers do not have to scroll to the bibliography. It also automatically extracts figures, tables, and key findings, displaying them on the paper's profile page. This interactive reading experience allows researchers to assess the validity of supporting evidence without losing their place in the text. By surfacing critical data visualisations and equations directly, the reader helps scholars quickly evaluate the experimental design and statistical results. This tool is particularly beneficial for interdisciplinary researchers who need to comprehend technical details outside their primary area of expertise.
Research Corpus and API Integration
Semantic Scholar provides the Semantic Scholar Academic Graph (S2AG), a massive dataset of academic papers, authors, and citations. Through its open API, the platform serves as the foundational data source for numerous third-party AI research assistants, search engines, and bibliometric tools. This open-science approach encourages the development of novel utilities for the global academic community. Researchers can access this dataset to conduct bibliometric studies, analyse collaboration networks, or build custom recommendation systems. By providing free and open access to high-quality metadata, Semantic Scholar supports the democratisation of research tools. It allows developers and researchers alike to explore large-scale academic trends without the financial barriers associated with commercial citation databases.

Common misconceptions
What people often get wrong
Often heard: Semantic Scholar requires a paid subscription to access its citation database.
Actually: Semantic Scholar is entirely free and non-profit, funded as part of the Allen Institute's commitment to advancing open science.
Often heard: A higher citation count on Semantic Scholar always indicates a better paper.
Actually: While total citations are displayed, the platform encourages looking at "highly influential citations" to assess actual academic impact.
Often heard: Semantic Scholar hosts full-text versions of all indexed papers on its servers.
Actually: It indexes metadata and abstracts, providing links to publisher sites, open-access repositories, and PDF archives where available.
Common questions
FAQ
How does Semantic Scholar determine if a citation is highly influential?+
It uses a machine learning model that analyses the context of the citation in the citing paper. Citations are deemed influential if the paper uses the cited methodology, reproduces the results, or explicitly builds upon the findings.
Can I add my missing publications to Semantic Scholar?+
Yes. Authors can claim their profile on Semantic Scholar and manually request the indexation of missing papers by submitting their DOIs or publisher URLs to the support system.
