摘要
立足于Ingwersen的检索交互认知模型,进行基于认知论的信息检索融合影响因素研究,对于信息检索融合的理论深化和方法拓展具有重要意义。本文以检索交互认知模型为基础,系统地探讨和分析了信息检索融合的影响因素:检索性能、认知差异性、系统可比较性、样本分布、系统数量和算法基准信息等。根据检索交互认知模型的系统、信息对象(信息空间)和认知行动者这三大组件,对信息检索融合的影响因素进行统一归纳,提出了基于认知论视角的信息检索融合影响因素框架。与此同时,在iSearch测试集的基础上,利用多个信息检索模式和典型的信息融合方法,对信息检索融合的影响因素进行了统一实验探讨和验证,实验结果验证了这些影响因素的统一性和正确性。在后续的研究中,将加强对影响因素的定量分析以及临界条件的获取研究,更多优秀数据集的支撑,也是未来的研究方向。
