基于相关性的情感分类方法

Correlation-Based Method for Sentiment Classification

Hussam Hamdan

摘要:

经典的监督分类算法是有效的,但耗时,复杂且不可解释,这使得难以分析其结果,从而限制了基于真实观察改进它们的可能性。在本文中,我们提出了一个新的和一个简单的分类器来预测一个简短的文本的情感标签。该模型保持了人类可解释的能力,并可以扩展到以更可解释的方式集成NLP技术。我们的模型是基于一个相关性度量,衡量情感标签和单词之间的关联程度。提出了十个相关性度量,并进行了内在评价。然后提出了一个分类器的基础上的每一个度量,评估和比较经典的分类算法,已经证明了他们的性能在许多研究。我们的模型优于这些算法与几个相关性指标。

英文摘要:

The classic supervised classification algorithms are efficient, but time-consuming, complicated and not interpretable, which makes it difficult to analyze their results that limits the possibility to improve them based on real observations. In this paper, we propose a new and a simple classifier to predict a sentiment label of a short text. This model keeps the capacity of human interpret-ability and can be extended to integrate NLP techniques in a more interpretable way. Our model is based on a correlation metric which measures the degree of association between a sentiment label and a word. Ten correlation metrics are proposed and evaluated intrinsically. And then a classifier based on each metric is proposed, evaluated and compared to the classic classification algorithms which have proved their performance in many studies. Our model outperforms these algorithms with several correlation metrics.
