多模态信息搜索行为实验研究

Experimental Research on Multi-modal Information Search Behavior

[目的/意义]研究多模态信息搜索特征有利于发现用户在图文音频信息搜索过程中的特征,进一步丰富多模态信息搜索以及信息行为的理论研究,为多模态信息系统建设和多模态信息素养提升提供依据。[方法/过程]本研究依托经典的信息搜索行为理论,通过实验法和统计分析法,分析受过高等教育群体的多模态信息搜索行为特征,提出多模态信息系统开发与设计和多模态信息素养提升建议。[结果/结论]通过实验研究,发现目前多模态信息搜索在准确性上表现较好,而完整性上则表现较差。在需求阶段需求理解上比较费时,普遍存在重复确认现象。在搜索方式上仍以文字搜索和跨平台搜索为主,且搜索策略调整次数较多,在搜索模态上转变较频繁。在信息收集上集中于百科类网页,特别是百度百科占了绝大多数,而社交媒体和电商应用软件也成为用户的多模态信息来源之一。

[Objective/Significance]Research on the characteristics of multimodal information search is helpful to discover the characteristics of users in the process of audio-visual information search,and further enrich the multimodal information.The theoretical research of information search and information behavior provides the basis for the construction of multimodal information system and the improvement of multimodal information literacy.[Method/process]This study is based on Based on the classical information search behavior theory,this paper analyzes the multi-modal information search behavior characteristics of the group with higher education through experimental method and statistical analysis,and puts forward multi-modal.The development and design of the state information system and the suggestion of improving multimodal information literacy.[Result/Conclusion]Through experimental research,the accuracy of current multimodal information search is shown in the table above The present is better,but the integrity of the performance is poor.It takes a long time to understand the requirements in the requirement stage,and there is a common phenomenon of duplicate confirmation.The search method is still text search.The cross-platform search is mainly based on cable and cross-platform search,and the search strategy is adjusted more frequently,and the search mode changes more frequently.Focus on encyclopedic web pages for information collection,especially.Baidu Encyclopedia accounts for the vast majority,while social media and e-commerce applications have also become one of the multimodal sources of information for users.
