Automatic Transformation of Clinical Narratives into Structured Format

no code implementations RANLP 2021 Sylvia Vassileva, Gergana Todorova, Kristina Ivanova, Boris Velichkov, Ivan Koychev, Galia Angelova, Svetla Boytcheva

For the “Diagnosis” section a deep learning text-based encoding into ICD-10 codes is applied using MBG-ClinicalBERT - a fine-tuned ClinicalBERT model for Bulgarian medical text.

Comparative Analysis of Fine-tuned Deep Learning Language Models for ICD-10 Classification Task for Bulgarian Language

no code implementations RANLP 2021 Boris Velichkov, Sylvia Vassileva, Simeon Gerginov, Boris Kraychev, Ivaylo Ivanov, Philip Ivanov, Ivan Koychev, Svetla Boytcheva

In our research study all BERT models are fine-tuned with additional medical texts in Bulgarian and then applied to the classification task for encoding medical diagnoses in Bulgarian into ICD-10 codes.

Deep learning contextual models for prediction of sport event outcome from sportsman's interviews

no code implementations RANLP 2019 Boris Velichkov, Ivan Koychev, Svetla Boytcheva

We test the hypothesis that the sports results can be predicted by using natural language processing and machine learning techniques applied over interviews with the players shortly before the sport events.

Risk Factors Extraction from Clinical Texts based on Linked Open Data

no code implementations RANLP 2019 Svetla Boytcheva, Galia Angelova, Zhivko Angelov

The idea is to determine whether a patient has risk factors for a specific disease analyzing only his/her outpatient records.

Mining Association Rules from Clinical Narratives

no code implementations RANLP 2017 Svetla Boytcheva, Ivelina Nikolova, Galia Angelova

Unfortunately, most frequent pattern mining approaches do not use contextual information for extracted patterns: general patterns are extracted regardless of the context.

Identification of Risk Factors in Clinical Texts through Association Rules

no code implementations RANLP 2017 Svetla Boytcheva, Ivelina Nikolova, Galia Angelova, Zhivko Angelov

We describe a method which extracts Association Rules from texts in order to recognise verbalisations of risk factors.
