About

What is the advantage of using Semantic Scholar instead of Google Scholar, PubMed or other academic searches?

Semantic Scholar helps researchers find better academic publications faster. Our engine analyzes publications and extracts important features using machine learning techniques. The resulting influential citations, images and key phrases allow our engine to “cut through the clutter” and give you results that are more relevant and impactful to your work.

Does Semantic Scholar share its data for research?

Semantic Scholar is committed to supporting high-impact research and engineering by providing universities and organizations access to our data. Please visit http://labs.semanticscholar.org/corpus/ to find data to support your research. We request that any published research that makes use of this data cites the paper provided.

How many articles does Semantic Scholar currently index?

We have millions of articles in our index and continually add more. We use a variety of carefully tuned mechanisms to make sure we only index high-quality publications.

If a valuable publication appears to be missing from our index please send us a publicly accessible link where we can access the publication in PDF form.

Please note, we are unable to add papers from social sites like ResearchGate and Google Scholar at this time.

If a publication seems to be low-quality or irrelevant, please

Does Semantic Scholar support the claims made within papers currently indexed?

The goal of Semantic Scholar is to leverage AI research and engineering to utilize methods from data mining, natural-language processing, and computer vision to make research more widely available to the global public. Semantic Scholar does not endorse or support any claims made within any papers currently available on the site.

What is a "Beta" feature?

A Beta feature is one that we make available early, while our engineers are still actively working on it. Beta features often still have rough edges and continue to evolve quickly, and we especially welcome on them.

Search

How are documents ranked?

We use a relevance function for ranking documents that takes into account many different aspects of the query and the publication details to provide the most relevant results.

You can sort your search results by selecting between the “relevance” and “recency” options in the dropdown menu in the upper-right on the search results page.

Does Semantic Scholar support Boolean search terms?

Yes, you may search for papers on Semantic Scholar using AND / OR query terms.

Do search terms and names need to be capitalized?

No. Our search engine is not case sensitive.

Does Semantic Scholar recognize abbreviations and acronyms? (i.e., KDD versus knowledge discovery and data mining)

We do some query expansion for author names, but otherwise we do not expand abbreviations and acronyms. For accurate results, please provide full keywords.

How do you extract topics from publications?

We use machine language techniques to analyze publications and extract topic keywords that balance diversity, relevance and coverage relative to our corpus.

Is there a publicly accessible API?

Yes, you can find it here.

We also provide access to a subset of the corpus as a single artifact at http://labs.semanticscholar.org/corpus/.

Citations

How does Semantic Scholar estimate citation counts?

Semantic Scholar estimates the number of citations for each publication based on the data in its corpus of several million publications. At times, our corpus omits obscure publications, publications from outside of Computer Science, etc. As a result, the number of citations per publication (and per author) shown is based on a statistical model that computes a range for the “true” number of citations.

What are Highly Influential Citations?

Semantic Scholar identifies citations where the cited publication has a significant impact on the citing publication, making it easier to understand how publications build upon and relate to each other. Influential citations are determined utilizing a machine-learning model analyzing a number of factors including the number of citations to a publication, and the surrounding context for each. You can read more about our approach in “Identifying Meaningful Citations”.

What is Citation Velocity?

Citation Velocity is a weighted average of the publication’s citations for the last 3 years and fewer for publications published in the last year or two, which indicates how popular and lasting the publication is. Out calculation is based off of estimated citation counts derived by Semantic Scholar. You can read more about this here.

What is Citation Acceleration?

Citation acceleration measures the change in a publication’s citation velocity over time, indicating whether the number of citations for a publication is increasing or decreasing. We divide the change in citation velocity over the last two years to calculate citation acceleration. You can read more about this here.

What is the Author Influence Score?

The influence score measures the impact of one author’s publications on another author’s work. The number is relative to the author whose profile is currently being viewed. The score is based on a weighted combination of citations and Highly Influential Citations.

How do I cite publications that I find on Semantic Scholar?

You can cite any papers that you find on Semantic Scholar by clicking the ”Cite” icon under the title and authors listed on a publication page or in the search results. A pop-up will offer you the option of multiple citation formats including BibTex, EndNote, MLA, APA or Chicago.

If there’s a citation format you’d like that we don’t offer, please
.

How do I add my publications to Semantic Scholar?

If you are an author that would like to see more of your content in Semantic Scholar, please a publicly accessible link where we can access a PDF or your paper(s).

Please note, we are unable to add papers from social sites like ResearchGate and Google Scholar at this time as well as hyperlinks designed for immediate download.

What types of content do you include in Semantic Scholar?

Our current corpus includes research publications related to computer science and biomedicine. We index content from PubMed, ArXiv, Springer Nature, and many more publishers.

How do I access the full text of a paper?

When you find a paper you’re interested in reading, click on the paper title. This will navigate you to the publication’s main page where you can find either a link to the PDF or to the paper’s source site.

On the publication main page, look for the blue and white buttons below the abstract of the paper. Here, you will see options to "Save," "Watch Paper," "Cite" and "View PDF" or "View on [Source]." [Source] can be research databases such as ArXiv, Pubmed, etc.

In order to access the full text of a paper, select the option that says "View PDF" or "View on [Source]." This will re-direct you to the full text of the paper or the source site where you may find the best options for accessing the paper you’re interested in.

Do you provide articles that are behind paywalls?

We have some articles that are only available behind paywalls, but the data we have for those articles is limited. We plan to expand our coverage and quality of paywalled content in the future. If you are a publisher that would like to see your content in Semantic Scholar, please .

What is a Lit Review and how do you determine that a publication is an overview?

Lit reviews are publications that provide a survey or high-level explanation of a field or topic. Our system utilizes a series of heuristics to determine if a publication is classified as an overview by analyzing the document’s content and wording.

Does Semantic Scholar include publications in other languages than English?

We currently offer publications published primarily in English, but we hope to support other languages in the future. If there’s a specific language you would like us to consider, please .

I’d like to have an author profile on Semantic Scholar. What can I do?

Author profiles are created automatically. Once Semantic Scholar discovers a publicly accessible publication on the internet, metadata is then extracted from the publication source and an author profile is automatically generated based on that metadata.

If you’d like to have an author profile on Semantic Scholar or if you already have publications available online but don’t see them on our site, please send us a publicly accessible link to your publication in PDF form and we’d be happy to add it to our site.

Corrections

I’ve noticed an error in the author citation for an article. How do I correct it?

If you notice an author correction needed on Semantic Scholar, there are two options for you to help resolve this:

First, if you don’t yet have an author profile on Semantic Scholar, you may send us publicly accessible links to PDF versions of your publications so we may submit index requests to add your papers. This would automatically generate an author profile for you and assist our machine-learning models in deciphering author-paper correlation.

Second, you may follow these steps to notify us of any corrections needed on the site.
  1. Visit the author page that has been incorrectly credited for the publication.
  2. Beneath the author’s name, you will find an option to "Suggest Changes." Follow this button to suggest corrections for specific publications.
  3. Scroll down the page until you see a field titled "Remove Papers."
  4. In this field, you can search through the publications currently credited to that author on our site. Search for the publication you’d like to suggest for removal.
  5. To suggest a publication for removal from a certain author, click the "X" icon to the left of the publication. You will then see this publication listed under "Papers to be removed."
  6. Complete this request by selecting "Submit Suggestions" at the bottom of the page.

I’ve noticed an error in the author name for an article. What is the reason for this error?

Due to the nature of citation formats, authors sharing similar names can provide a challenge for Semantic Scholar’s author disambiguation tool. We are working hard on improving the methods in which our machine-learning models decipher author/paper correlation given the citation format but sometimes these author corrections can take some time to correct. We sincerely appreciate your patience as we work to develop preventative measures for this.

My citation counts appear incorrect. How can I report this error and how can it be resolved?

Our citation count is weighted towards relevant articles in the index. If you are an author that would like to see more of your content in Semantic Scholar, please a publicly accessible link where we can access a PDF of your papers(s).

Please note, we are unable to add papers from social sites like ResearchGate and Google Scholar at this time.

If you find that we already index most of your content but you wish to make changes, please use the "Submit Suggestions" feature on your author profile to notify us of the changes you’d like to see.

I’ve noticed an error in the metadata provided for my articles. How do I correct it?

If you see a problem with our publication metadata, please so we can improve our disambiguation process in the future.
