NCU IISR System for NTCIR-11 MedNLP-2 Task
نویسندگان
چکیده
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. We also use CRFs to detect the modalities of the ICD-10 mentions. To resolve the problem of ICD-10 mention normalization, we use the Lucene engine to link mentions to the corresponding ICD-10 database entries. Evaluated on the MedNLP test set, our system achieved f-scores of 79.96% for ICD-10 term recognition, 67.64% for time expression and 69.4% for ICD10 mention normalization.

This paper describes our approach to the NTCIR-12 MobileClick task. First of all, we do some extra process on the baseline. Next, we try to use a totally different method from baseline which is machine learning. Finally, tune the two types into better situation and apply them to test data. Our system achieves an nDCG@3 score of 0.7415, nDCG@5 score of 0.764, nDCG@10 score of 0.8059, nDCG@20 sco...
متن کاملOverview of the NTCIR-11 MedNLP-2 Task
Electronic medical records are now often replacing paper documents, and thus the importance of information processing in medical fields has increased. We have already organized the NTCIR-10 MedNLP pilot task. It has been the very first shared task attempt to evaluate technologies to retrieve important information from medical reports written in Japanese, whereas the NTCIR-11 MedNLP-2 task has b...
