Outline of Final Research Achievements

We developed a text mining method to extract feature words of search result using SVM (support vector machine). We succeeded to find small number of feature words that characterize the documents. We extended the bootstrap method for a measurement of generality and specificity of feature words.
We confirmed the effectiveness of the methods by applying them to analyze the real data of scientific articles, students' free comments, English writing errors, security reports, medical records and Web documents.
