An ontology tree coding method based on the equal-length of the same parent and child nodes counting

Abstract

The invention belongs to the field of WEB service discovery, in particular to an ontology tree coding method based on the equal length of the same parent and child nodes. The method can be divided into three steps: A. describing and analyzing the concept of ontology for topological sorting; B. carrying out binary coding on the ontology tree of the same length as the parent and the child node countaccording to the topological sorting sequence; C. conceptual preservation of the corresponding encoding. The invention provides an ontology tree coding method based on the equal bit length of the same parent and child nodes, so as to overcome the inefficiency of the semantic-based Web service discovery method.

Description

technical field [0001] The invention belongs to the field of WEB service discovery, and can be used to quickly and accurately find services that meet user requirements and constraints. Specifically, it is an ontology tree coding method based on equal-length equal-length node counts of the same parent and child. Background technique [0002] With the continuous development of the world wide web (world wide web), the application programs on the network have grown explosively. Since the network is a distributed, dynamic and heterogeneous environment, how to make better use of these massive resources brings traditional information technology At the same time, the service-oriented architecture came into being, and its main purpose is how to make full use of a large amount of information that exists in a distributed, heterogeneous, and dynamic environment. As the mainstream technology of SOA (Service-Oriented Architecture), Web service has also been greatly developed and is gradua...

Problems solved by technology

Because the traditional Web service discovery is based on syntax and keyword matching, because of the lack of necessary semantic information, it cannot fully and accurately describe the relevant information of the service, and the description language has certain ambiguity and ambiguity, which will seriously affect the The accuracy rate and recall rate of service discovery make the promotion and application of SOA affected to a certain extent

Semantic-based Web services overcome the above shortcomings, but the current semantic-based service discovery still has certain problems in automatic service discovery, not only in terms of service discovery effects but also in terms of execution efficiency. There is still a lot of room for improvement
