Abstract
In the face of the mature and popular development of Internet technology,digital library has become an important institution to provide people with information resources.However,in the face of the development environment of data isomerization and decentralization,the traditional information retrieval system of digital library can no longer adapt to the increasing information retrieval needs of users,and it is difficult to correctly judge the retrieval intention of users.there are some problems,such as low retrieval efficiency and inaccurate detection results.Based on this,combined with semantic web technology,this paper designs the module,process and system structure of the framework model of digital library information retrieval system.On this basis,it gives the methods of domain ontology integration and construction and semantic similarity algorithm optimization,in order to provide reference for the scientific construction of digital library information retrieval system,and thus maximize the utilization value of digital library information resources.关键词
