# rubert-entity-embedder

RuBERT Entity Embedder \(Russian, cased, 12‑layer, 768‑hidden, 12‑heads, 180M parameters\) is based on [DeepPavlov's RuBERT-base-cased](https://huggingface.co/DeepPavlov/rubert-base-cased). It is fine-tuned as a Siamese neural network to build effective token embeddings of 29 entity classes on Russian [1]. The fine-tuning procedure is the first stage of two-stage fine-tuning of a BERT-based language model for more robust named entity recognition [2].
