Research On Mobile Visual Search Of Digital Library Based On Service Mashup

With the rapid growth of digital visual resources,how to organize and manage massive and closely related visual resources has become the direction of research and practice of various information service organizations.The improvement of mobile terminal intelligence,mobile internet technology and mobile network communication technology has provided support for the development of mobile visual search organizations,and promoted the transformation and upgrading of various organizations'information services.As an emerging technology and service model,mobile visual search technology makes up for the simplification of information resources,management,and utilization through the convenient collection of real-world visual objects through mobile terminals,but it also brings information services to various information service organizations.New opportunities and challenges.Many scholars have conducted in-depth discussions on mobile visual search resource organization,service model,search mechanism and model construction in libraries,archives,museums,etc.,but due to the lack of digital visual library's ability to have mobile visual search related information technology,traditional The library organization structure and the mobile visual search architecture are not suitable,and the mobile visual search service cases that can be used for reference are less.The application of mobile visual search in the digital library and other fields is slow.In order to overcome the difficulties and challenges in the development of digital library mobile visual search organization,this paper proposes a service mashup-based approach to help digital libraries avoid the problems of related information technology development,technical development funding,and organizational structure.Service mashup refers to decomposing a target into a number of tasks or roles in order to achieve a certain service goal.The business process is determined according to the operational steps and the relationship between the tasks or roles.In the actual application process,according to the tasks in the business process or The role selects related resources,technologies,or service components,and uses computers to communicate information and documents between multiple participants to achieve communication between services,thereby generating new,value-added resource content or service products,and achieving service goals.The entire service mashup organization process reflects the core idea of the workflow,with flexibility and scalability.In the process of mobile visual search organization of digital library based on service mashup,according to the workflow of mobile visual search basic business process planning service mashup,flexibly call related visual technology to realize mobile visual search service,simplify the organization of digital library mobile visual search And technical requirements.This paper sorts out the connotation,basic framework,key technologies and specific applications of mobile visual search,and finds the opportunities and challenges faced by mobile visual search in digital libraries.On this basis,the research questions of this paper are put forward.In order to solve the difficulties and challenges faced by the digital library mobile visual search organization,this paper is based on the theory of service mashup and service quality evaluation,and analyzes the necessity and feasibility of using the service mashup method to organize the digital library mobile visual search service in an open environment.The mobile library visual search organization model based on service mashup is the empirical object of plant information mobile visual search.The feasibility and practicability of the model are verified.
