在本研究中，我们提出了一个方案，以探讨修改关系的情感关键字标注和情感类型识别的重要性。从汉语情感语料Ren-CECps中提取了程度词、否定词和连词三种修饰特征。除了词和词性外，本文还选取了三种修饰关系作为特征。我们进行了八个实验，不同的特征集的情感关键词标注和情感类型识别的句子水平。选取了八种基本的情感类型，并采用条件随机场作为算法。在评价部分，我们论证了修改特征的重要性，实验结果表明修改特征对于提高情感关键词标注和情感类型识别的性能是有效的。
In this study, we make a scheme to explore the importance of modification relation for the emotional keywords annotation and emotion types recognition. We extract three modification features which are degree words, negative words and conjunctions from the Chinese emotion corpus named Ren-CECps. Beside word and part-of- speech, three modification relations are adopted as feature in this study. We have carried out eight experiments with different feature sets for emotional keywords annotation and emotion types recognition in sentence level. Eight basic emotion types have been selected and Conditional Random Fields have been employed as the algorithm. In the part of evaluation, we demonstrate the importance of the modification features and our experiment results show the effective- ness of the modification features for improving the performance of emotional keywords annotation and emotion types recognition.
