    A Probabilistic Precision Information Retrieval Model for Personalized Clinical Trial Recommendation based on Heterogeneous Data
    (Institute of Electrical and Electronics Engineers Inc., 2021) Kamath S․, S.; Veena Mayya; Priyadarshini, R.
    In modern healthcare practices, diagnosis and treatment for certain complex illnesses require specific information on the. patients' background, genealogy, heredity, demographic data etc. Even with a similar diagnosis, treatments may need to designed specifically to adapt well to the patients' genetic, cultural, and lifestyle aspects. Precision medicine mainly deals with enabling personalized care based on a given patient's conditions in a scientifically rigorous way. Because this entails recommending personalized therapies to patients and has the potential to affect the health of other people, the performance of a designed system must be accurate and exact. In this paper, a precision information retrieval system is proposed that leverages structured and unstructured data to retrieve. relevant knowledge for enabling personalized recommendations, The. proposed pipeline is validated with the cllnlcal trial dataset of the Precision medicine track of TREe 2017. A set of relevant ranked clinical trials for a given condition/disease that could not be cured using any of the traditional treatments suggested are retrieved using structured and unstructured patient data. 'We employ multiple IR techniques like Best Match 25, query reformulation and rearanking facilitated through deep neural networks, focusing on extracting highly accurate and relevant trials. The proposed pipeline achieved a high score of 0.58 in terms of Normalized Discounted Cumulative Gain (NDCG) score for ranking the relevant clinical trials, outperforming the state-of-the-art approaches. © 2021 IEEE.
