Five retrieval models with six pre-processing strategies on different parts of medical records are explored on an NTUH medical record dataset. Both coarse-grained relevance evaluation on department level and fine-grained relevance evaluation on course and treatment level are conducted. Query accesses to the medical records in medical languages of smaller entropy tend to have better performance. The departments related to generic parts of body such as Departments of Internal Medicine and Surgery may confuse the retrieval, in particular, for Departments of Oncology and Neurology. Okapi model with stemming achieves the best performance on both department and course and treatment levels. Copyright ? by the paper's authors. |
