摘要
网络信息可信度关乎决策的有效性程度。社会化媒体、移动互联及大数据环境下的网络信息具有用户主动参与、信息多源异构及海量动态等新的特征。新的网络环境下，信息交流过程越来越扑朔迷离，信息的真实性或可信度越来越受到人们的关注，特别是针对信息质量中信息可信度评估及测度的研究越来越多。本文尝试基于相关研究文献，梳理网络信息质量及其可信度的含义、可信度的影响因素及相应的评估方法等方面的相关研究成果，分析现有研究在可信度测度、随机样本选择、可信度评估设计模型构建及标准语料库构建等方面的不足，进而提出相应的可能研究方向。
It is important to improve Web information credibility for the validity of decision.
