Bibliographic search is one of the most important basic services of digital library.It is increasingly difficult for the existing bibliographic search system to meet uses'needs along with the development of mobile Internet and the accumulation of web data,.First of all,search results of current bibliographic search systems are not conducive to the user's resource discovery be'cause they are usually organized by MARC,which is a linear data organization method and makes the results data has almost no connection with each other.Secondly,the search form of current bibliographic search system is basically a traditional text input type and most systems don't adapt their search page to mobile device,which makes the search operation on mobile device inconveniently.The emergence of linked data and mobile visual search provided a new opportunity for digital library.On this occasion,this paper conductes a research on improving the quality of digital library bibliographic search service with linked data and mobile visual search.Firstly,this paper summarizes the research status of converting bibliographic information into linked data and mobile visual search of digital library.Then introduces the related concepts and key technologies of linked data and mobile visual search.After that,a framework of mobile visual search platform of digital library bibliographic resource are introduced and the components of the framework are also introduced.Finally,taken bibliography cover as example,the platform of bibliography cover search by mobile visual search is developed and tested.The main contributions of this paper are confined as follows:(1)This paper analyzes the problems existing in the current bibliographic search platform in digital library,and provides the development direction for the construction of the bibliographic search platform.Digital library should try to convert their bibliographic information to linked data and enrich the search form of bibliographic resource by mobile visual search.(2)This paper presentes a framework of bibliographic mobile visual search platform in digital library,which can provide practical reference for digital library to construct their mobile visual search service.(3)The complete implementation of the proposed platform framework is a tentative exploration of the practical of constructing digital library mobile visual search service.The limitations of this research are mainly embodied in the implementation part of the search platform.For the implementation of mobile visual search,the quality of the cover picture is not good,which makes the image matching accuracy still has to be improved.Besides,the response speed of the search system could not be verified because we had limited bibliographic data.Besides,the bibliographic ontology model is not perfect because of the small number of bibliographic information metadata fields.Moreover,only the link between internal resources is realized and the link between internal resource and external resource still remains to be realized.
