Citation Edges, Topics, Venues and Matching Records to DOI or PubMed
Citation edges come as their own records rather than as a count. Each edge links a citing and a cited paper and carries the contexts - the sentences around the reference in the citing paper's body - the intents drawn from Background, Method and Result, and the isInfluential flag, so a citation graph arrives ready to query instead of needing to be read.
Topic and venue pages add two layers the paper record lacks. A topic page carries a definition with the ontology that supplied it, and a venue page holds the full publication list with filters for fields of study, date range and PDF availability, which turns a journal or conference into a complete list of its papers.
Author records carry authorId, name, affiliations with ROR identifiers, paperCount, citationCount, hIndex and ORCID or DBLP ids, and we build no named researcher profiles or contact lists from them.
Matching runs on identifiers, not titles. Every paper record carries its externalIds - DOI, ArXiv, PubMed, PubMedCentral, Medline, MAG, ACL, DBLP and CorpusId - which is how a Semantic Scholar extract joins onto PubMed, arXiv or an internal DOI list.
