Abstract:
A system for managing outcome information based on URI comprises an outcome information managing unit that registers and manages outcome information; a URI managing unit that is connected to the outcome information managing unit and imparts a URI to the outcome information through a URI server so as to manage the outcome information; and a knowledge extending unit that is connected to the outcome information managing unit and the URI managing unit and extends knowledge by using an inference rule for an inference service based on the Semantic Web.

Abstract:
A DBMS-based knowledge extension and inference service method recorded on a computer-readable medium includes creating knowledge represented as a triple by using ontology schemas and instances (first step); receiving the knowledge and extending the knowledge by using a knowledge extension rule (second step); and providing an inference service by using the extended knowledge, converting a user query, and processing the query (third step). Further, the third step includes receiving and converting a user query to create the converted query (31st step); determining whether the query is a previously-input query (32nd step); receiving the converted query and the determination result to create a query result (33rd step); receiving the query result of the 33rd step and performing post-processing to create a post-processing result (34th step); and creating a message and protocol suitable for a user interface by using the post-processing result and then presenting an inference result.
Abstract:
A DBMS-based knowledge extension and inference service system comprises a knowledge creating unit that creates knowledge represented as a triple by using ontology schemas and instances; a knowledge extension processing unit that receives the knowledge created by the knowledge creating unit and extends the knowledge by using a knowledge extension rule; and an inference service providing unit that uses the knowledge extended by the knowledge extension processing unit and converts and processes a user query so as to provide an inference service. In the DBMS-based knowledge extension and inference service system, ontology is used to create knowledge, the knowledge is extended by using an extension rule, and an inference service is provided through query processing, thereby proposing a framework which is stable and effective in all fields where the Semantic Web is utilized and an inference service needs to be provided. Therefore, it is possible to achieve the common use of the Semantic Web service.
Abstract:
A system for managing sameAs relationships between ontology instances comprises a sameAs relationship managing unit that checks, sets, or cancels sameAs relationships between ontology instances; a sameAs group knowledge processing unit that receives an input for setting or canceling sameAs relationships from the sameAs relationship managing unit and then corrects related knowledge within ontology instance data; and a sameAs inference service providing unit that uses the knowledge corrected by the sameAs group knowledge processing unit, processes a user query, and performs sameAs post-processing so as to present the result.
Abstract:
A system for registering instances based on history is disclosed. An instance registration setting unit reads ontologies and storing them in memory, and provides an interface capable of editing one or more instances included in each of classes. The instances are provided through an ontology viewer for visualizing relationships between the stored ontologies. An instance registration editing unit edits, searches for, and registers the instances using the interface provided by the instance registration setting unit, and supports the editing by extracting one or more object names based on external information while managing the edited instances based on the history.
Abstract:
Provided is a system for providing integrated search using a URI database, the system including a URI database that stores associated information corresponding to a specific entity as object identifiers; an entity information processing unit that searches a URI database in accordance with a query input of a user so as to check the type of an entity and provides entity information; and an integrated-search result providing unit that provides an integrated-search result page for the corresponding entity, based on the entity information provided from the entity information processing unit.
