基于改进K-Means算法的教学反思文本聚类研究
Research on Text Clustering of Teaching Reflection Based on Improved K-Means Algorithm
摘要
Abstract
An accurate assessment of teaching reflection content is an important guarantee based on teachers' teaching reflection process to enhance their professional capabilities. Clustering the same theme of the teaching reflection text based on an improved K-Means algo-rithm,through given the initial cluster center K a value ranges,so that it can be automatically increased within the given range,during the clustering process,similarity threshold is introduced to limit the reflection texts' similarity ranges,realizing the teaching reflection text classification and the self-reflection text classification. The experiment result indicates the improved algorithm has a higher accuracy,bet-ter stability,and can accurately automatically classify according to the teaching reflection content.关键词
