What Semantic Scholar covers
Semantic Scholar is Allen Institute for AI's cross-disciplinary corpus. It indexes more than 200 million papers with citation graphs, extracted key phrases, TLDR summaries, and influence scores, spanning computer science, neuroscience, biomedical sciences, and beyond.
Semantic Scholar's citation graph is ideal for finding influential papers and tracking research threads. Relaylit uses Semantic Scholar alongside discipline-specific sources (PubMed, arXiv) to catch cross-disciplinary papers that pure keyword search would miss.
