Disclosed herein is a multi-entity-centric integrated search system and method. The multi-entity-centric integrated search system includes an entity information acquisition server for receiving and analyzing a query term and determining entities and types of entities, and an integrated search result provision server for configuring an integrated search results page using results acquired from unit service calling units, such as an external API calling unit, a search engine calling unit, and an inference engine calling unit, and presenting integrated search results. The present invention is advantageous in that precise search results can be shown more rapidly, satisfaction with search results for a query term in which multiple entities coexist can be improved, the ambiguity of query terms is overcome, and an open platform capable of operating in conjunction with various types of web services is provided.

A system and method for hybrid Rete reasoning based on memory and DBMS are provided. The system for hybrid Rete reasoning based on memory and DBMS includes a reasoning rule type classification means for classifying an input reasoning rule as one of one or more types. A network generation means generates a network depending on the classified reasoning rule type. A network execution means derives extended triples by applying a predetermined triple to the generated network.

An efficient reasoning system and method using a view in a DBMS-based RDF triple store are provided. The DBMS-based reasoning system includes a triple input unit for receiving a Resource Description Framework (RDF) triple. A triple examination unit examines whether the received triple conforms to RDFS subsumption relation entailment rules or Web Ontology Language (OWL) inverse relation rules. A view creation unit creates a table view when the received triple conforms to the RDFS subsumption relation entailment rules or the OWL inverse relation rules as a result of the examination. A triple storage unit stores the received triple. The DBMS-based triple store can efficiently perform reasoning based on rule rdfs7 or rdfs9, which is included in the RDFS subsumption relation entailment rules, and the OWL inverse relation rules.

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 (st step); determining whether the query is a previously-input query (nd step); receiving the converted query and the determination result to create a query result (rd step); receiving the query result of therd step and performing post-processing to create a post-processing result (th step); and creating a message and protocol suitable for a user interface by using the post-processing result and then presenting an inference result.

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.

The present invention relates to a system and method for managing connection between web services. The system includes an external web service connection setup server for determining an external web service to which connection is to be made, and establishing and verifying connection rules, and an external web service connection management server for conducting tests on connection to the external web service and storing the results of the tests. The system may further include a component for searching a connection target DB in which connection results are stored, and transmitting connection results to a main web service server, a component for removing a hyperlink to a failure page, and a component for sensing a sudden increase in a connection failure ratio. Accordingly, external web services belonging to all fields desired by a network manager can be easily, rapidly and efficiently connected.
