BioinformaticsUA: Machine Learning and Rule-Based Recognition of Disorders and Clinical Attributes from Patient Notes
نویسندگان
چکیده
Natural language processing and text analysis methods offer the potential of uncovering hidden associations from large amounts of unprocessed texts. The SemEval-2015 Analysis of Clinical Text task aimed at fostering research on the application of these methods in the clinical domain. The proposed task consisted of disorder identification with normalization to SNOMED-CT concepts, and disorder attribute identification, or template filling. We participated in both sub-tasks, using a combination of machine-learning and rules for recognizing and normalizing disease mentions, and rule-based methods for template filling. We achieved an F-score of 71.2% in the entity recognition and normalization task, and a slot weighted accuracy of 69.5% in the template filling task.

A Novel Approach to Conditional Random Field-based Named Entity Recognition using Persian Specific Features
Named Entity Recognition is an information extraction technique that identifies name entities in a text. Three popular methods have been conventionally used namely: rule-based, machine-learning-based and hybrid of them to extract named entities from a text. Machine-learning-based methods have good performance in the Persian language if they are trained with good features. To get good performanc...

متن کاملMachine learning based Visual Evoked Potential (VEP) Signals Recognition
Introduction: Visual evoked potentials contain certain diagnostic information which have proved to be of importance in the visual systems functional integrity. Due to substantial decrease of amplitude in extra macular stimulation in commonly used pattern VEPs, differentiating normal and abnormal signals can prove to be quite an obstacle. Due to developments of use of machine l...
