Abstract

Abstract: Against to the shortcoming of strong subjectivity and the lack of deep-layer semantic information in existing internal evaluation of automatic summarization，by using probability latent semantic analysis to calculate the contribution on semantics including the original document and summaries，and then the similarity is compared.The summary which matches to semantic information of original document is got.Without human intervention，the results show that the evaluation method based on the semantic similarity has the feature of simplicity and stability and is closer to the natural model.

Key words: automatic summarization, evaluation method, probabilistic latent semantic analysis, similarity

摘要： 针对现有自动文摘内部评价方法存在主观性强，无法体现深层语义的缺陷，提出利用概率潜在语义分析计算原文和待评价摘要在潜在语义上的贡献，通过相似度的比较，得出符合原文语义的文摘。整个评价方法无需人为干预，实验表明，基于语义相似度的评价方法实现简单、效果稳定，是一种更接近自然模型的评价方法。
