Large-scale scientific research on historical documents — particularly medieval Arabic manuscripts — remains challenging due to the need for advanced paleographic and linguistic training, the large volume of hand-written materials, and the absence of assisting software. In this paper, we propose InkSight, the first end-to-end Arabic manuscript analysis tool for manuscript-based analytics and research hypothesis testing. InkSight integrates three key components: (i) an Optical Character Recognition (OCR) module utilizing a Large Visual Language Model (LVLM); (ii) a lightweight document indexing and information retrieval module that enables query-based evidence retrieval from book-length manuscripts; and (iii) a flexible Large Language Model (LLM) prompting interface factually grounded to the given manuscript via Retrieval-Augmented Generation (RAG). Empirical evaluation on the existing KITAB OCR benchmark and our in-house dataset of ancient Arabic manuscripts has revealed that historical research can be effectively supported using smaller fine-tuned LVLMs without relying on larger proprietary models. The live web demo for InkSight is available freely at: https://inksight.ru and the source code for InkSight is publicly available at Github: https://github.com/ds-hub-sochi/InkSight-tool.

We present RuCCoN, a new dataset for clinical concept normalization in Russian manually annotated by medical professionals. It contains over 16,028 entity mentions manually linked to over 2,409 unique concepts from the Russian language part of the UMLS ontology. We provide train/test splits for different settings (stratified, zero-shot, and CUI-less) and present strong baselines obtained with state-of-the-art models such as SapBERT. At present, Russian medical NLP is lacking in both datasets and trained models, and we view this work as an important step towards filling this gap. Our dataset and annotation guidelines are available at https://github.com/AIRI-Institute/RuCCoN.

Medical data annotation requires highly qualified expertise. Despite the efforts devoted to medical entity linking in different languages, available data is very sparse in terms of both data volume and languages. In this work, we establish benchmarks for cross-lingual medical entity linking using clinical reports, clinical guidelines, and medical research papers. We present a test set filtering procedure designed to analyze the “hard cases” of entity linking approaching zero-shot cross-lingual transfer learning, evaluate state-of-the-art models, and draw several interesting conclusions based on our evaluation results.
