C. Data Layer Data Layer is posed of three parts: ontology library, education resource Description Database and MySQL/DB2/oracle Database. As the storage medium of knowledge resource ontology, this layer is responsible for creating and refining a structural description of the OWLbased knowledge ontology, which is the direct source of knowledge retrieval. In addition, in order to achieve knowledge sharing and reuse, it will carry out semantic annotation to the relevant resources in the web page and store them in the ontology library by the data acquisition ponents. Fig 1. Ontologybased Framework for Network Education Resources Library IV. KEY TECHNOLOGIES OF FRAMEWORK In this section the key technologies of this framework are presented. It includes web services, processing of user request, semantic parsing and inference engine. A. Web Services Representation Layer may also be known as the Network Service Layer, its main task is to achieve interaction with the user. Under the case of a variety of the resource building ways, the web service technologies are selected in order to integrate distributed resource library of education effectively and share information between them. On the basis of a variety of heterogeneous platforms, Web Services are available to build a mon platformindependent, languageindependent technical level, which applications of different platform rely on to implement the connection and integration between them. Throughout the resource library, as a service provider, each local resource make their own services and features promulgate to the global system, which UDDI (Universal Description Discovery and Integration) on it. And then the UDDI is responsible for the registration and sending. In this, all the information is send to the entire system through the SOAP (Simple Object Access Protocol). B. Processing of user request In our framework, user takes on resource search by an ordinary bination method that fields are limited or natural statement. Learning objects belong to different local resources, they are geographically separated. Different resource libraries are usually built on different puter platforms, data formats and programming languages, which provide their own mechanisms to query and access resources. In this case, the central server needs a certain mechanism to orient local resource libraries that can provide server, and then user request will be sent to local servers. In the specific system design, we refer to a number of mathematical methods [8]. Figure 2 illustrates how a user request to be processed by these modules. C. Semantic parsing In our framework, semantic parsing is responsible for the transition from the user requests submitted by search engine to concepts of ontology. The conversional process of user semantic to machine presentation need query ontology library, analyze user intents and use Jena Owl inference mechanism to plete. As user query are uncertainty in a certain degree, it is feasible that expand the concept set of queries according to the needs of users. Semantic expansion rule is defined as: If O is Literlas type, then S is the center of expansion, the concepts for a query can be obtained according to the concepts and attribute relations of S. If S does not exist, the concepts are not to be taken. If
