چکیده

This year’s MedNLP-2 [1] has two tasks: Extraction task (Task 1) and Normalization task (Task 2). We tested both machine learning based methods and an ad-hoc rule-based method for the two tasks. For the Extraction Task, a two-stage approach (first, the machine learning based method is applied to identify c tags, and second, the rule-based method is applied to modality features) obtained higher results. For the Normalization Task, the machine learning based method obtained higher results for training data, but the simple pattern-matching method obtained higher results for test data.

NCU IISR System for NTCIR-11 MedNLP-2 Task

This paper describes NCU IISR’s Japanese ICD-10 Code Linking system for NTCIR-11 MedNLP. Our system uses Conditional Random Fields (CRFs) to label ICD-10 mentions and temporal expressions.
