Firstly, external knowledge is used to enhance the role of emotional words in sentences, and the part-of-speech is used for information filtering to remove redundant dependencies in sentences to obtain pruned syntactic dependency trees. The two are combined by mult...

aspect的获取往往没有分离的提取和分类。最近也有一篇是利用RBM来同时提取aspect和sentiment,将aspect和sentiment作为RBM中分离的隐藏节点,然而这个模型依赖于先验知识,例如part-of-speech(POS) tagging词性标注和sentiment lexicons情感词典。 A biterm topic model(BTM)可以生成co-occurring word pairs。
位置(即句子中每个词相对于方面的相对位置)嵌入和词性(part-of-speech, POS)嵌入的维度设为30。因此,我们将单词、POS和位置嵌入连接起来,然后将它们输入到BiLSTM模型中,该模型的隐藏大小设置为50。为了减轻过拟合,我们在BiLSTM的输入词嵌入中采用了0.7的dropout。SynGCN和SemGCN模块的dropout率设置为0.1,SynGCN和...

过去的研究中:一个方法是从一组没有label的信息中累积aspect和opinion terms,通过使用句法规则或modification relation between them,但是这个方法太依赖于hand-coded rules并且is restricted to certain Part-of-Speech(POS)词性,例如:opinion words是形容词。 另一个方法是:基于定义好的lexicons词汇,句法分析。labeling...
One line of work on aspect extraction detects aspect expressions using linguistic patterns (e.g. part-of- speech and dependency relations) (Hu and Liu, 2004; Joshi and Rose, 2009; Zhuang et al., 2006; Wu et al., 2009; Qiu et al., 2011) or supervised sequence labeling such as CRFs...
Research on the development of aspect marking in four Chinese speaking children showed that le was the most frequently used aspect marker by the children at the age of 1;4 and remained so in their speech at the age of 3;5, accounting on average for nearly 90% of all aspect markers used...
