摘要

通过研究有关基因的生物学文献特征

提出了一种能对生物基因文献进行自动标注与分类的方法.在K最邻近算法的基础上

采用了Chi-Square特征选择方案

并且在加权算法中突出了Chi-Square的选择特点.另外

采用文档逻辑分块法

将额外的生物受控词汇表中的信息所形成的向量直接引入到了分类算法中

以提高分类和标注的效果.实验表明

所提算法优于常用的单词频率/逆文档频率加权方法

其在文本检索大会(TREC)数据集上的分类、标注效果分别比TREC公布的最好结果提高了3.14%和4.12%.

Abstract

Based on the K nearest neighbor algorithm

an improved method was proposed for selecting genes-related documents from biology literature

and then automatically annotating and classifying. The method employs the Chi-Square feature selection plan and highlights the Chi-Square selections in weighted calculations. Furthermore

the effect of classification and annotation was improved by dividing the documents into logical blocks and introducing additional vectors from biological resources MeSH into the classification algorithm directly. Experiment results show that the proposed method is better than the commonly used TFIDF(term frequency and inverse document frequency)weighting method

and the results tested on TREC(text retrieval conference)data sets are 3.14% higher in classification and 4.13% higher in annotation comparing to the best results announced TREC.
