【摘要】:該文主要識別產(chǎn)品評論中的條件句并分析其傾向性,判斷評論者對產(chǎn)品屬性持積極或是消極的態(tài)度。條件句中一般都含有條件連接詞,但是有些條件句中沒有條件連接詞,稱為隱式條件句。經(jīng)過觀察,發(fā)現(xiàn)隱式條件句中含有一些體現(xiàn)條件關系的詞,稱之為隱式條件詞。識別條件句時,主要依據(jù)條件連接詞和隱式條件詞及其詞性以及類序列規(guī)則進行分類;分析屬性傾向性時,依據(jù)條件連接詞和隱式條件詞把條件句分為假設條件句、讓步條件句、特定條件句和無條件句四類,并把條件句的類別用于SVM分類。通過實驗證明了該方法有助于條件句傾向性分類。
[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.
