大數據環境導致數據密集型科研范式產生,知識服務機構的服務模式也已轉變為以用戶為中心。在這種情況下,知識資源存在動態復雜的關系,科研用戶需求更加多樣,傳統文本信息檢索方式已不能完全滿足用戶需求。移動視覺搜索在搜索方式上可以滿足泛在環境下用戶對知識服務的要求,在檢索內容上滿足用戶對圖像資源以及與之相關的文本信息的需求。因此,本研究在分析移動視覺搜索模型構建動因的基礎上,提出一種大數據環境下面向科研用戶的移動視覺搜索模型,為移動視覺搜索理論的深入和其在知識服務領域中的應用拓展提供參考。

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.
