摘要
在基于词典和规则的文本褒贬分析过程中,常常会出现一些多极性的形容词,例如"大"、"小"、"轻"、"重"、"长"、"短"等等。由于此类形容词的褒贬性具有极强的上下文相关性,因此,只能通过上下文搭配关系来确定其褒贬性。通过多种途径从语料中收集与多极性形容词的搭配词,构建搭配词表,解决多极性形容词的褒贬倾向性问题。实验表明,所使用的方法能够提高多极性形容词褒贬性判别的准确率,并进一步提高文本褒贬分类的准确率。
Frequently there will be some multipolar adjectives such as ＂big＂,＂small＂,＂light＂,＂heavy＂,＂long＂ and ＂short＂,etc.encountered in the process of text appraisement analysis based on dictionary and rules.Since the appraising property of such kind of adjectives has strong context correlation,therefore only by the context collocation can them be determined the appraising property.We collect the words collocating with multipolar adjectives through a variety of ways from the corpus and build a collocation table to solve the appraising inclination problem of multipolar adjectives.Experiments show that the method we used is able to improve the accuracy of judgement on appraising property of multipolar adjectives and further the accuracy of the text appraisement classification.
