摘要
提出一种体验评价性文章判定、抽取模型,并构造原型系统完成博客体验评价文章抽取的评价实验。该模型基于文章的基本表现特征和简单的规则,不需要进行详细的语法语义分析,只需以文章中出现的体验对象、体验行为、体验评价描述短语三者搭配强度和距离来计算、判定文章是否为体验评价性文章。评价实验结果表明基于该模型的系统具有较高的抽取精度。
In this paper, an extraction model of experience and evaluation article is proposed, and an evaluation experiment about experience and evaluation article extraction from blogs is achieved. This model depends on collocation degree and distance of experience object, experience action, and experience evaluation instead of syntax analysis. The results of the experiment show that, the system based on this model achive high extraction precision.
