BioVITAI2TRetrieval

An MTEB dataset

Massive Text Embedding Benchmark

Measures fine-grained visual species recognition posed as retrieval. Each query is a wildlife photograph, and the model ranks 100 candidate taxa -- the photographed taxon plus 99 distractors -- represented by their taxon names in a 325-entry text index. A taxon scores the highest similarity over its own index entries and the 100 taxa are ranked by that score, so the reported taxon_top_k_accuracy is taxon-level rather than document-level. Runs 1,352 queries at species level and 992 at genus level over BioVITA's held-out unseen split: 325 species excluded from training and the 225 genera they belong to.
