用户认知对标签使用行为的影响分析——基于电影社会化标注数据的实证分析

Analysis of the Influence of User Cognition on Tag Use Behavior

为分析用户认知对标签使用行为的影响,文章从资源特征认知难度和用户认知风格两个方面展开分析,基于认知心理学的研究成果提出相应假设,并将其转化为可以量化分析的标签统计特征,以更直接、客观地加以检验。在此基础上,基于Movielens社区中81部影片的高频标签和675351位豆瓣电影社区用户的标签数据对假设进行了检验。结果表明,用户认知对其标签使用行为具有显著影响,其中资源特征认知难度的增加会显著降低该特征被标注的可能性,而用户认知风格则会导致其在标注上具有明显的个人倾向。该结论对社会化标签的应用研究和社会化标注系统的设计均具有启发意义。

In order to analyze the influence of user cognition on tag use behavior,this paper carries on the analysis from two aspects,including cognitive difficulty and user＇ s cognitive style. The paper proposes hypotheses based on the cognitive psychology achievements,and transforms into the quantitative analyzed tag statistics,which in order to test more directly and objectively. On the basis of this,the paper tests the hypotheses based on the high-frequency tags of 81 movies in the Movielens community and675351 data tags in the Douban movie community. The result shows that user＇ s cognition has great impact on tag use behavior： the increase of the cognitive difficulty of resource features can significantly reduce the label possibility of the feature; and user cognitive style can lead to a significant personal tendency on the label. The conclusion is instructive for the application of social tagging and the design of social tagging system.
