摘要:

配对比较法是心理学中的一种既定方法。在这篇文章中,它被应用到获得连续的情感分数的话,从测试人员的比较。我们创建了一个初始的词汇与$n=199$德语单词从一个双重的所有对比较实验与10个不同的测试人员。从考虑的概率模型,逻辑模型显示出最好的协议与比较实验的结果。最初的词典可以以不同的方式使用。一种是通过添加任意词来创建专用情感词典,这些词由测试人员与一些初始词进行比较。一个交叉验证实验表明,只有大约18个双重比较是必要的,以估计一个新的,但未知的词的分数,提供这些词是由Silverstein & Farrell的方法的修改选择。初始词典的另一个应用是评估自动创建的基于语料库的词典。通过这样的评估,我们比较了基于语料库的词典SentiWS,SenticNet和SentiWordNet,其中SenticNet 4表现最好。本技术报告是2016年ICDM Sentire研讨会上所做演示的更正和扩展版本。

英文摘要:

The method of paired comparisons is an established method in psychology. In this article, it is applied to obtain continuous sentiment scores for words from comparisons made by test persons. We created an initial lexicon with $n=199$ German words from a two-fold all-pair comparison experiment with ten different test persons. From the probabilistic models taken into account, the logistic model showed the best agreement with the results of the comparison experiment. The initial lexicon can then be used in different ways. One is to create special purpose sentiment lexica through the addition of arbitrary words that are compared with some of the initial words by test persons. A cross-validation experiment suggests that only about 18 two-fold comparisons are necessary to estimate the score of a new, yet unknown word, provided these words are selected by a modification of a method by Silverstein & Farrell. Another application of the initial lexicon is the evaluation of automatically created corpus-based lexica. By such an evaluation, we compared the corpus-based lexica SentiWS, SenticNet, and SentiWordNet, of which SenticNet 4 performed best. This technical report is a corrected and extended version of a presentation made at the ICDM Sentire workshop in 2016.
