中文摘要: 用户生成内容(UGC)既增加了网络信息的虚假及冗余程度,又为网络信息的真伪甄别及其需求相关性甄别提供了可能性。为了克服虚假及冗余信息的干扰,本研究拟从用户生成内容的大众标注视角,基于其内在的大众选择机制,运用社会选择理论、群体选择理论、社会网社区划分理论、统计推断及模拟理论,构建网络信息的语义性甄别模型。主要工作有:(1)基于协同选择的用户需求与信息内容的交互效应及其协同选择机制分析;(2)基于关联选择的社区或领域性概念空间形成模型构建及其关联选择机制分析;(3)特定社区或领域性概念空间中信息内容与用户需求的甄别及匹配模型构建;(4)基于学习性选择的概念空间更新模型构建及其学习性选择机制分析;(5)基于实证研究、行为实验及仿真模拟,对相关机制及模型进行有效性评价。相关研究成果可丰富集体智慧、社会选择及群体选择等理论,并可为社会化搜索、个性化推荐及网络舆情监测等应用提供相关理论及方法。

英文摘要: The approach of user generated content (UGC) can not only intensify the degree of false or redundant about Web information, but also provide possible condition for improving the objective reality and demand relevance in the process of Web information acquisition. To eliminate the interference of false or redundant Web information, this research try to construct semantical discrimination models by the theories of social choice, group selection, community partition of social network,and statistical inference and similation based on the related mechanisms of collective choice from the perspective of social annotation or comment about Web information in the process of user generated content.The main contents studied in this research are as follow: (1)Analyze the interactive effect between information content and user's demand based on collaberative choice, and analyze the mechanism of collaborative choice; (2)Construct the model about formation or evolution of community or domain concept space based on associative choice, and analyze the mechanism of associative choice; (3) Construct the model about discrimination or match of information content and user's demand in relevent community or domain concept space; (4)Constuct the model about evolutive update of concept space based on learning choice, and analyze the mec
