【摘要】：该文主要识别产品评论中的条件句并分析其倾向性,判断评论者对产品属性持积极或是消极的态度。条件句中一般都含有条件连接词,但是有些条件句中没有条件连接词,称为隐式条件句。经过观察,发现隐式条件句中含有一些体现条件关系的词,称之为隐式条件词。识别条件句时,主要依据条件连接词和隐式条件词及其词性以及类序列规则进行分类;分析属性倾向性时,依据条件连接词和隐式条件词把条件句分为假设条件句、让步条件句、特定条件句和无条件句四类,并把条件句的类别用于SVM分类。通过实验证明了该方法有助于条件句倾向性分类。
[Abstract]:This paper identifies conditionals in product reviews and analyzes their tendency to judge whether reviewers have a positive or negative attitude towards product attributes. Conditional sentences generally contain conditional connectives, but in some conditional sentences there are no conditional connectives, which are called implicit conditional sentences. After observation, it is found that there are some words in implicit conditional sentences, which are called implicit conditional words. In identifying conditional sentences, they are mainly classified according to conditional connectors, implicit conditional words and their parts of speech and the rules of class sequence, and conditional sentences are classified into hypothetical conditional sentences according to conditional connectors and implicit conditional words when analyzing attribute tendency. Concessional conditional sentence, specific conditional sentence and unconditional sentence are divided into four categories, and the category of conditional sentence is used in SVM classification. It is proved by experiments that this method is helpful to conditional sentence tendency classification.
