What is Semantic Scholar?
Semantic Scholar is an academic search tool launched by the Allen Institute for Artificial Intelligence (Ai2). Its official website defines it as a free tool that uses AI and engineering methods to understand the semantics of scientific literature and help researchers discover relevant research. It is more than just title search: the results page comes with AI-generated TLDR short summaries, the paper page allows viewing high-impact citations and related topics, and you can directly ask questions about a single paper. The official homepage shows that the number of retrievable papers exceeds 200 million, covering all scientific fields. There are also APIs and an API Gallery for developers.
Who is it for?
- Graduate students and researchers who are embarking on a new direction and need to quickly grasp the context of the field
- People doing literature reviews who use high-impact citations and research alerts to narrow their reading scope
- Writers who need to batch export citations in formats such as BibTeX
- Researchers who track the latest citations of a specific author or a particular paper
- Engineers who want to perform secondary development using large-scale literature data
- Researchers looking for interdisciplinary sources who can't think of the right keywords to search with
Key features
6Semantic Search
The official website states that it can search papers across all scientific fields and supports filtering by journals and conferences, authors, publication types, and time ranges.
TLDR Summary
An ultra-short abstract generated by AI that summarizes the main objectives and findings of the paper. According to the official, it covers nearly 60 million papers in the fields of computer science, biology and medicine.
High-Impact Citations
The official states that machine learning models are used to filter out citations that have a significant impact on the citing papers, helping users prioritize important ones among a large number of citations.
Library & Research Alerts
After logging in, you can save papers to an online library, organize them into folders, export citations in bulk, share folders for collaborators to copy with one click, and enable AI-powered research alerts for folders to receive regular recommendations of new papers.
Alerts & Author Pages
You can set up new citation alerts for a specific paper, or follow authors to get alerts about their new papers; after claiming your author page, you can view the latest citation status of your own papers.
Paper Q&A and Topic Pages
The Ask This Paper feature on the paper page allows you to ask questions about the article with supporting sentences from the original text attached; the Topics page compiles AI-generated definitions, highly cited papers, and related topics, and the official states that it is currently only open to the computer science field.
How to use Semantic Scholar
- First, filter out irrelevant content using TLDR and summaries, then read the full text.
- Do not get stuck in full-text perusal during the retrieval stage.
- After identifying several core papers, place them in the same literature library folder and enable research alerts.
- The official recommendation is to include 5 relevant papers and mark 3 irrelevant ones as irrelevant to train the recommendation system, which will significantly speed up the convergence rate.
- For citation lists, prioritize high-impact citations, then trace back along the chain.
- Ask This Paper is officially stated to be currently available only on some papers and has mainly been tested on English papers, so exercise caution when using it across languages.
- Topics and some capabilities are in beta or limited scope, and the coverage may change, subject to the current official website instructions.
- Note that it does not include the full texts of all paid databases.
- access the original text through institutional subscriptions or publisher channels when off-campus.
