SciEmbed-BASE
Signal A only (citation edges), 7M pairs, 3 epochs. The citation-edge baseline that isolates what Signal B adds.
A 149M-parameter ModernBERT-base scientific document embedder trained with citation-context sentences as the primary contrastive signal. Part of the SciEmbed release (Findings of EMNLP 2026).
Usage
