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:
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:

Abstract:
A method for providing a technology trend displayed on a technology lifecycle graph, which is performed by a technology trend providing system, is provided. The method includes (a) obtaining year-specific stages or year-specific representative principal agents with respect to a specific technology displayed on the technology lifecycle graph; and (b) displaying the year-specific stages or the representative principal agent in each year with respect to the specific technology on the technology lifecycle graph. Thus, according to the present invention, it is possible to provide the year-specific stages and the year-specific representative principal agents with respect to each technology displayed on the technology lifecycle graph.
Abstract:
An apparatus and method of searching and visualizing an instance path. The method includes receiving two or more keywords and path search condition; generating a pair of instances with respect to the keywords, extracting a pair of classes corresponding to each of the pairs of instances from ontology instance database; obtaining an ontology schema path with respect to each of the pairs of classes from ontology schema path database; replacing start and end classes with corresponding first and second instances in each of the ontology schema paths and searching for instance path corresponding to the path search condition from the instance paths connected between the first instance and the second instance; outputting instance path display screen on which the searched instance paths are displayed; and if the path search condition changes through the instance path display screen, obtaining and visualizing instance paths corresponding to the changed path search condition.
