信息检索中的广义作用效应链应用研究

Study on the Generalized Function-effect Chain in Information Retrieval

广义作用句和广义效应句的划分是作用效应链思想在句类体系中的体现。这一划分是对自然语言语句的一个最基本的分类。如果结合信息检索中采取的统计学办法,在检索结果的基础上进行二次精筛选,则提供给查询用户的结果必将更符合实际需求,能更有效提高信息检索的正确率。从人为数据统计结果来看,这一思路有效地把统计方法和基本规则方法结合起来,提高了信息检索的检索准确率。

The division of the generalized function sentence and the generalized effect sentence is the embodiment of the function-effect chain thought in the sentence category system. The division is the most basic classification to the natural language sentence. If we combine the statistics method and the rule method in the information retrieval and carry on the second filter to the results, the final result will conform to the actual demand for the inquiry user＇s and effectively enhance the correct rate of the information retrieval. The artificial data statistics result proved that the method effectively combines the statistics means with the rule means and improves the correct rate of the information retrieval.
