Abstract: The present invention provides methods and apparatuses for processing a gateway device fault. According to one embodiment, when a fault on a gateway device is detected, computing tasks currently executed by the faulty gateway device are acquired; to-be-allocated computing tasks are screened out according to parameters configured when the computing tasks are issued; the computing tasks running on the faulty gateway device are terminated, and the to-be-allocated computing tasks are scheduled to other gateway devices in a normal state according to a preset scheduling strategy. Further, task states of the to-be-allocated computing tasks are recovered, and the to-be-allocated computing tasks are executed by the other gateway devices. Embodiments of the present application can help avoid the problem that computing tasks fail due to a fault occurring in the gateway device, thereby the overall execution efficiency of the computing tasks and ensuring system stability.

Abstract: A method for semantic service registration and query based on WordNet is disclosed. The method includes the following steps: (1) semantic service registration: a service provider registers a service and uploads the Web Service Description Language (WSDL) document corresponding to the service, and a system parses the WSDL document to form a service description tree, then constructs a WordNet ontology tree according to the input of the service, performs a semantic annotation on the input/output of the service to form a Web Service Semantic Description Document (WSDL-S), and finally stores it in a register library; (2) semantic service discovery: a service requester inputs the information of service type, semantic information of the service input/output and other user-defined information to the register library to retrieve the services meeting the requirements; and (3) similarity sorting: the services meeting a certain threshold are sorted in descending order.
