大数据环境下面向科研用户的移动视觉搜索模型研究

Research on the Mobile Visual Search Model for Scientific Research Users in Big Data Environment

大数据环境导致数据密集型科研范式产生,知识服务机构的服务模式也已转变为以用户为中心。在这种情况下,知识资源存在动态复杂的关系,科研用户需求更加多样,传统文本信息检索方式已不能完全满足用户需求。移动视觉搜索在搜索方式上可以满足泛在环境下用户对知识服务的要求,在检索内容上满足用户对图像资源以及与之相关的文本信息的需求。因此,本研究在分析移动视觉搜索模型构建动因的基础上,提出一种大数据环境下面向科研用户的移动视觉搜索模型,为移动视觉搜索理论的深入和其在知识服务领域中的应用拓展提供参考。

The big data environment leads to the generation of data intensive scientific research paradigm,and the service patterns of knowledge service organizations also start to orient to the users. Under this circumstance,knowledge resources become more complex and the demands of scientific research users become more diversified,so the traditional text-based information retrieval model can not fully meet the needs of users. Mobile visual search can meet the needs of users for knowledge services in the ubiquitous environment from the search mode,as well as for image resources and the associated text information from search content.Therefore,the paper proposes a mobile visual search model for scientific research users under the big data environment,which provides references for the further development of mobile visual search theories and related practices in knowledge service field.
