System and method for semantic service

A semantic service management server coupled to a semantic broker server and configured to support semantic services, the semantic service management server comprising:

• a semantic service management unit for collecting pieces of ontology-based semantic service information and ontology from a plurality of service servers, registering the pieces of ontology-based semantic service information and ontology with a semantic service repository or an ontology integration management unit, and managing the pieces of ontology-based semantic service information and ontology;
• an ontology integration management unit for registering and integrating the pieces of ontology, distributed among the respective service servers which is collected by the semantic service management unit, supporting reference to the integrated ontology when semantic services are registered, deleted, and edited, and supporting information search performed by the semantic broker server;
• and
• a semantic service repository for storing the pieces of semantic service information collected by the semantic service management unit and supporting the search of the semantic broker server.

A semantic service method of a system, comprising a semantic service management server, a semantic broker server, and a semantic service license server, providing ontology-based semantic services, the semantic service method comprising the steps of:

• a) the semantic service management server collecting pieces of ontology-based semantic service information and ontology distributed among a plurality of service servers and registering the pieces of ontology-based semantic service information and ontology;
• b) the semantic service license server outputting preset items so that an input factor is inputted and requesting classes and instances matched with an input factor inputted by a user by transmitting the input factor to the semantic broker server;
• c) the semantic broker server requesting class and instance information, matched with the input factor, from the semantic service management server when the request is received from the semantic service license server, receiving the class and instance information from the semantic service management server, and transmitting the received class and instance information to the semantic service license server;
• d) the semantic service license server outputting the preset items so that an output factor is inputted and requesting a result matched with a condition, including the input factor and the output factor, by transmitting the condition to the semantic broker server;
• e) the semantic broker server requesting semantic service information, matched with the condition, from the semantic service management server, receiving the semantic service information from the semantic service management server, generating semantic service pipelines based on the received semantic service information, and transmitting the semantic service pipelines to the semantic service license server;
• f) the semantic service license server outputting the semantic service pipelines received from the semantic broker server so that the user can check the semantic service pipelines and requesting the semantic broker server to execute a semantic service pipeline selected by the user;
• g) the semantic broker server receiving an Application Programming Interface (API) of the semantic service pipeline, requested to be executed by the semantic service license server, from the relevant service server by calling the API and transmitting a relevant result to the semantic service license server;
• and
• h) the semantic service license server outputting the relevant result received from the semantic broker server.

A semantic service method of a semantic service management server, performing communication with a semantic broker server, providing ontology-based semantic services, the semantic service method comprising the steps of:

• a) the semantic service management server collecting and registering pieces of ontology-based semantic service information and ontology distributed among a plurality of service servers;
• and
• b) the semantic service management server supporting search of the semantic broker server for ontology information or semantic service information,
• wherein the semantic service management server further collects an ontology reference Application Programming Interface (API) and separately stores the collected ontology reference API, if the ontology reference API exists, or the semantic service management server stores relevant instance information itself, if the ontology reference API does not exist, at the step a).

A semantic service method of a semantic service license server, performing communication with a semantic broker server, providing ontology-based semantic services, the semantic service method comprising the steps of:

• a) the semantic service license server outputting preset items so that an input factor is inputted and requesting classes and instances, matched with an input factor inputted by a user, by transmitting the input factor to the semantic broker server;
• b) the semantic service license server receiving class and instance information, matched with the input factor, from the semantic broker server;
• c) the semantic service license server outputting the preset items so that an output factor is inputted and requesting a result, matched with a condition including the input factor and the output factor, by transmitting the condition to the semantic broker server;
• d) the semantic service license server outputting semantic service pipelines transmitted by the semantic broker server so that the user can cheek the semantic service pipelines and requesting the semantic broker server to execute a semantic service pipeline selected by the user;
• and
• e) the semantic service license server outputting a result transmitted by the semantic broker server.
