Embodiment Construction

[0026] In order to make the objective technical solutions and advantages of the present invention clearer, the present invention will be further described below in conjunction with the embodiments and the drawings of the specification.

[0027] The method of the present invention includes the following seven steps:

[0028] Step 1) Construct a domain ontology. The content of the construction includes the concepts in the domain, the attributes of the concepts, the relations between the concepts, and the constraints of the attributes and relations. Ontology construction is an engineering work. This system uses the tool protégé developed by Stanford University to construct ontology. The model layer of the ontology is relatively small compared to the data layer. The model layer constructed includes classes, data attributes, object attributes, and the relationships between classes and attributes, including equivalence and inheritance. Such as figure 1 As an ontology constructed. Its s...

Abstract

The invention discloses an event publishing and subscribing method supporting fuzzy matching based on ontology, and the method allows a publisher and a subscriber to build an RDF event and an SPARQL statement with key word description through a browser on the basis of the domain ontology. The domain ontology stipulates the relationship between a concept in a certain field and a concept and is expressed by adopting the OWL; an event model stipulates the event expression means and is expressed by an RDF graph; a subscription request stipulates the subscription expression means and is expressed by the SPARQL statement and key words. In matching, firstly, events which meet the subscriber event type requirements are obtained by utilizing the upper and lower reasoning of the ontology; secondly, the relevancy score between the key words and the events is obtained through calculation by utilizing the relevancy measurement means in the information theory, and sequencing is performed on the events which meet the subscription requirements by utilizing the relevancy score; lastly, the sequenced event collection is returned to a user, and therefore fuzzy matching of event publishing and subscribing can be achieved.

Description

Technical field [0001] The invention belongs to the field of computer technology and relates to an ontology-based publishing and subscribing matching method. Background technique [0002] Publish and subscribe system refers to a middleware system that can provide users to participate in message forwarding in the roles of publisher and subscriber. The forwarded message is also called an event in this patent, where the publisher and subscriber are the systems The most basic role. Subscriber and publisher roles can be owned by the same system end user, that is, an end user can be both a subscriber and a publisher. The publisher is the producer of the event, and the subscriber is the consumer of the event. Subscribers express their interest in certain events through subscription statements, and the publisher publishes events in accordance with certain constraints in the publish-subscribe system, and the event passes through The matching algorithm is forwarded to a specific subscrib...
