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。

Abstract:

It is of great significance to study the cognitive influencing factors for information retrieval fusion based on the IIR model of Ingwersen for deepening theories and expanding methods. Based on IIR model, this paper systematically discusses and analyzes the factors that influence information retrieval fusion, including retrieval performance, cognitive differences, systematic comparison, sample distribution, system numbers and algorithm based information. This paper proposes a cognitive framework of influencing factors for information retrieval fusion based on IIR model. With some information retrieval schema, typical information fusion methods and experiments based on iSearch test collection, the authors systematically discuss and verify the proposed cognitive framework.In future research, the authors will focus on quantitative analysis and critical conditions of influencing factors, and try to find more excellent datasets to support the proposed conclusions.
