Using Dictionaries for Biomedical Text Classification

摘要

The purpose of this paper is to study the use of dictionaries in the classification of biomedical texts. Experiments are conducted with three different dictionaries (BioCreative [13], NLPBA [8] and a subset of the UniProt database [4], named Protein) and three types of classifiers (KNN, SVM and Naive-Bayes) when they are applied to search on the PubMed database. Dictionaries have been used during the preprocessing and annotation of documents. The best results were obtained with the NLPBA and Protein dictionaries and the SVM classifier.
