Embodiment Construction

[0031] The input and output of the service composition are the parameters describing the functional requirements of the user, the input of the atomic service node that the user starts with the input constraint of the service composition, and the output of the atomic service that ends with the output constraint of the service composition. The abstract atomic service in the service composition does not exist in isolation, so in the matching process, it needs to constrain its input parameters through the output parameters of the service instance matched by its predecessor service, and at the same time use the output parameters of its matching service instance to control its successor The input parameters of the service are constrained. In the service composition model, when the output parameters of atomic service A and the input parameters of atomic service B have a direct data flow transfer relationship, in the present invention, service A is called the front service of service B...

Abstract

The invention provides a contextualized spatial information service combination semantic matching method and belongs to the technical field of spatial information service. The semantic matching method provided by the invention is used for dynamically matching atomic services in an abstract service combination model and accurately and efficiently converting the abstract spatial service model into an executable spatial information service chain, under the condition of fully taking account of the limitation of the spatial information service combination to the matching of the interior abstract atomic services and the mutual contextual influence of the abstract atomic services in the matching process.

Description

technical field [0001] The invention belongs to the technical field of spatial information service semantics, and in particular relates to a new semantic matching method for spatial information service combination in consideration of context. Background technique [0002] Driven by global networking and information digitization, new technologies and applications such as web services and semantic web are constantly emerging. Massive spatial data, powerful computing resources, and rich spatial information processing functions are being provided to users in the form of services. , so that GIS faces new opportunities and challenges. [0003] With the increasing demand of users, it is difficult for a single spatial information service to satisfy users, which makes the emergence of a combination of spatial information services inevitable. Spatial information service combination is to use the distributed spatial information services on the network, according to the user's applicat...
