Abstract
This paper aims to evaluate the previous entity extraction methods and semantic similarity metrics in order to improve the entity extraction and semantic analysis process for narrative text in electronic medical records. With the dataset collected from Medical Information Mart for Intensive Care III (MIMIC-III), our results showed that WordNet-based lemmatization and Part of Speech tagging have more of a significant influence in medical text analysis. For the sematic similarity metrics, the experimental results show that the measure proposed by Lin, which is based on IC, has the highest correlation coefficient with the artificial dataset of r = 0.727. The metric combining Resnik and Tversky’s measures, which is based on features as well as IC, also has relatively stable performance, which indicates that IC and feature are the factors should be particularly considered for the future research.
