在这项工作中，我们介绍了SENTIWORDNET 3.0，这是一个明确为支持情感分类和观点挖掘应用程序而设计的词汇资源。SENTIWORDNET 3.0是SENTIWORDNET 1.0的改进版本，SENTIWORDNET 1.0是公开提供的用于研究目的的词汇资源，目前授权给300多个研究小组，并在世界各地的各种研究项目中使用。SENTIWORDNET 1.0和3.0都是根据所有Wordnet同义词集的积极、消极和中立程度自动注释它们的结果。SENTIWORDNET 1.0和3.0的不同之处在于：(A)它们注释的Wordnet的版本(分别为WordNet 2.0和3.0)，(B)用于自动注释Wordnet的算法，该算法现在包括(除了先前的半监督学习步骤之外)用于精炼分数的随机游走步骤。我们在这里讨论SENTIWORDNET 3.0，特别关注它相对于1.0版所体现的关于方面(B)的改进。我们还报告了针对手动注释的正性、负性和中立性的WordNet 3.0片段对SENTIWORDNET 3.0进行评估的结果；这些结果表明，与SENTIWORDNET 1.0相比，准确率提高了约20%。
In this work we present SENTIWORDNET 3.0, a lexical resource explicitly devised for supporting sentiment classification and opinion mining applications. SENTIWORDNET 3.0 is an improved version of SENTIWORDNET 1.0, a lexical resource publicly available for research purposes, now currently licensed to more than 300 research groups and used in a variety of research projects worldwide. Both SENTIWORDNET 1.0 and 3.0 are the result of automatically annotating all WORDNET synsets according to their degrees of positivity, negativity, and neutrality. SENTIWORDNET 1.0 and 3.0 differ (a) in the versions of WORDNET which they annotate (WORDNET 2.0 and 3.0, respectively), (b) in the algorithm used for automatically annotating WORDNET, which now includes (additionally to the previous semi-supervised learning step) a random-walk step for refining the scores. We here discuss SENTIWORDNET 3.0, especially focussing on the improvements concerning aspect (b) that it embodies with respect to version 1.0. We also report the results of evaluating SENTIWORDNET 3.0 against a fragment of WORDNET 3.0 manually annotated for positivity, negativity, and neutrality; these results indicate accuracy improvements of about 20% with respect to SENTIWORDNET 1.0.
