 The primary goal of the NLP working group is to promote the use of textual information from Electronic Health Records (EHRs) for observational studies under the OHDSI umbrella. To facilitate this objective, the group will develop methods and software that can be implemented to utilize clinical text for studies by the OHDSI community. The primary goal of the NLP working group is to promote the use of textual information from Electronic Health Records (EHRs) for observational studies under the OHDSI umbrella.

-**Title: Leveraging longitudinal and multi-modal EHR in Survival Analysis**\\ +**Agenda**
-**Abstract:​** Survival analysis is a fundamental statistical tool that predicts the time of an event. It has multiple healthcare applications in areas, such as hospitalization and patient mortality. Clinicians predict patient outcomes by heterogeneous modalities (e.g., text, images, and lab values). Such data poses significant challenges for traditional survival analysis techniques. In this talk, we present our effort to expand the survival analysis using multimodal, longitudinal EHR data. Our results indicate that extracted high-dimensional features from text and image provide complementary information in addition to structured EHR, and incorporating longitudinal data is useful in time-to-event prediction.+

-Dr. Peng is an assistant professor at the Department ​of Population Health Sciences at Weill Cornell MedicineHis main research interests include BioNLP ​and medical image analysissuch as named entity recognition,​ information extraction, and eye disease diagnosis ​and prognosisBefore joining Cornell MedicineDr. Peng was research fellow at the National Center ​for Biotechnology Information (NCBI)National Library of Medicine (NLM)National Institutes ​of Health (NIH)He obtained his Ph.D. degree from the University ​of DelawareDuring his doctoral training, he investigated applications ​of machine learning ​in biomedical relation extractionwith focus on deep analysis of the linguistic structures ​of biomedical texts.+**Title:** LeafAI: query generator for clinical cohort discovery rivaling a human programmer\\ 
 +**Abstract:​** ​ Identifying study-eligible patients within clinical databases ​is a critical step in clinical research. However, accurate query design typically requires extensive technical and biomedical expertise. We sought to create a system capable ​of generating data model-agnostic queries while also providing novel logical reasoning capabilities for complex clinical trial eligibility criteriaWe incorporated hybrid deep learning ​and rule-based modules for these, as well as a knowledge base of the Unified Medical Language System (UMLS) ​and linked ontologiesTo enable data-model agnostic query creationwe introduce ​novel method ​for tagging database schema elements using UMLS concepts. To evaluate our systemcalled LeafAIwe compared the capability ​of LeafAI to a human database programmer to identify patients who had been enrolled in 8 clinical trials conducted at our institutionWe measured performance by the number ​of actual enrolled patients matched by generated queriesLeafAI matched a mean 43% of enrolled patients with 27,225 eligible across 8 clinical trials, compared to 27% matched and 14,587 eligible ​in queries by a human database programmer. The human programmer spent 26 total hours crafting queries compared to several minutes by LeafAI. Finallywe introduce ​novel multimodal user interface for interaction with LeafAI.\\
