Abstract:
A method and apparatus for storing a triple and an inference dependency indexing apparatus appropriate to the method and system are provided. The method of storing a triple related to an inference method for creating other triples by applying an inference rule to the triple includes: (a) adding a serial number to each of triples and inference rules related to inference and storing the triples and the inference rules into a plurality of triple tables and inference rule tables; (b) indexing a triple inferred by applying the triple and the inference rule, using a serial number of the triple and a serial number of the inference rule related to inference; and (c) creating a triple view which allows accessing the triples physically distributed and stored in a plurality of triple storage units (tables) as if the triples are stored in a virtual storage unit (table).
Abstract:
An apparatus and method of searching and visualizing an instance path, which can search for a path between class-based instances and effectively display a path between two or more instances in order to rapidly search for diverse and complex relationships and search for a relationship between instances based on a relationship between classes in order to avoid comparison between the relationship being searched and the relationship of unnecessary objects when comparing the relationship between instances, are provided.
Abstract:
The present invention provides an apparatus and method for detecting a location of an underground facility, which calculates a gauss value at each depth of a magnetic marker, measures a magnetic field at each depth through each sensor based on the calculated gauss values, extracts factors by performing a factor analysis on the measured magnetic fields, obtains extracted variable values by performing a regression analysis on the extracted factors, stores the extracted variable values in a database, and determines a location of the magnetic marker based on the stored extracted variable values and the values measured by the sensors in real time.
Abstract:
A named entity dictionary update apparatus using a named entity dictionary and a mining rule combined with an ontology schema includes: a named entity dictionary and mining rule database storage module storing the named entity dictionary and a mining rule database; a named entity and mining rule search module searching for a corresponding mining rule and a named entity from the mining rule database and the named entity dictionary using a terminology included in an inputted mining pattern and the mining pattern; and a named entity dictionary update module estimating a named entity of the terminology using the mining rule and storing the estimated named entity of the terminology in the named entity dictionary depending on user's selection, if a named entity corresponding to the terminology is not searched from the named entity dictionary and the mining rule corresponding to the mining pattern is searched from the mining rule database.
Abstract:
Question-answer service system and method based on RDF search are provided. The question-answer service method includes: extracting a subject. a predicate, and an object from a text document composed of the unstructured sentences not having the structured format; creating RDF models composed of the extracted one subject, one predicate, and one object; determining whether there is semantic collision by comparing the RDF models; receiving a question including the subject S, the predicate P, or the object O from a user and being requested to search, on the basis of the constructed RDF network; creating a question for search by interpreting the input question;. searching an RDF model matching with the question for search through the RDF network; and providing a subject S, a predicate P, or an object O. which corresponds to an answer for the question from the searched RDF model.
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:
Related search service system and method based on the RDF network are provided. The related search service method includes: extracting a subject, a predicate, and an object from a text document composed of the unstructured sentences not having the structured format; creating RDF models composed of the extracted one subject, one predicate, and one object: determining whether there is semantic collision by comparing the RDF models; constructing an RDF network by separating the RDF models when there is semantic collision in the RDF models, and integrating the RDF models when there is no semantic collision; and providing service for searching the subjects or the objects which have the same predicate on the basis of the created RDF network.
Abstract:
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.
Abstract:
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.
Abstract:
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.
