Using the summarization evaluation system developed by this research to build the semantic space consist of three factors above. Then we analyze the correlation between cosine value cacluated by each semantic space and two teachers’s scoring. The participants are the 107 students of Er-Chong elementary school. After analysis of two summarizing experiments, the results of the research are: In experiment I, the correlation between two teachers’ grades and the LSA cosine is significant. But in experiment II, the correlation between two teachers’ grades and the LSA cosine is inconsistent. Therefore, base on the LSA cosine, we could not get the consistent results in different literary forms.摘要摘要寫作評量潛在語意分析奇異值分解語意空間summariessummaries evaluationLSASVDsemantic space
