基于摘要聚类的二语教育领域知识结构研究

An Analysis of Knowledge Structure in Second Language Education by Clustering Research Paper Abstracts

本文旨在分析二语教育领域的研究现状。通过对该领域30种期刊在1999—2007年间发表的4931篇论文的摘要进行聚类分析,从而得出了可以反映该领域主要研究方向的20个类团。借助这些类团的特征词和特征短语,笔者对各研究方向的研究内涵以及二语教育的主要知识结构进行了分析。研究结果表明,摘要聚类是一种有效的描述领域知识结构的方法。

This study aims to depict a panorama of the knowledge structure within the field of Second Language Education.A cluster analysis was conducted on the abstracts of 4931 research papers published in 30 journals from 1999 to 2007,yielding a 20-cluster division of this knowledge domain.The key topics of each cluster and the topical structure of Second Language Education as a discipline were analyzed based on the features(words and phrases) extracted from each cluster.The results indicate that cluster analysis of paper abstracts is a reliable method for describing the structure of a knowledge domain.
