Abstract:
An apparatus and method of searching for an instance path based on an ontology schema are provided. The method of searching for an instance path based on an ontology schema, which is performed by an instance path search apparatus, includes (a) receiving two or more keywords from a user and generating a pair of instances with respect to the keywords, respectively, (b) extracting a pair of classes corresponding to each of the pairs of instances from an ontology instance database, respectively, (c) obtaining an ontology schema path with respect to each of the pairs of classes from an ontology schema path database, respectively, and (d) replacing start and end classes with corresponding first and second instances in each of the ontology schema paths and searching for an instance path connected between the first instance and the second instance, respectively.
Abstract:
A module and method for determining a named entity of a terminology using a named entity dictionary and a mining rule combined with an ontology schema is provided. The module includes a named entity dictionary and mining rule database storing the named entity dictionary and a mining rule database; a mining pattern generation unit recognizing a terminology from a text and converting the terminology into a mining pattern; a named entity and mining rule search unit searching for a corresponding named entity and a mining rule respectively from the named entity dictionary and the mining rule database using the recognized terminology and the mining pattern; and a names entity selection unit selecting, if two or more named entities corresponding to the recognized terminology are searched, a named entity matching to the concept configuring the RDF triple of the searched mining rule as a named entity of the terminology among the searched named entities.

Abstract:
An apparatus and method for updating a named entity dictionary or a mining rule database using the named entity dictionary and a mining rule combined with an ontology schema is provided. The apparatus includes a named entity dictionary and mining rule database storage module storing the named entity dictionary and a mining rule database; a mining pattern generation module recognizing a terminology from a text and converting the terminology into the mining pattern; a named entity and mining rule search module searching for a corresponding named entity and a mining rule from the named entity dictionary and the mining rule database using the recognized terminology 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 a user's selection.
Abstract:
RDF network construction device and method using an ontology schema having class dictionaries and mining rules are provided. The RDF network construction device includes an ontology schema storing module, a class managing module, a mining rule managing module, a mining pattern creating module, and an RDF triple creating module.
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.
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.
Abstract:
The present invention relates to a melanin biosynthesis inhibitor containing terrein compound as an effective ingredient. The terrein compound can be easily separated from Penicillium sp KCTC 26245, a fungal strain inhabited in domestic soil. It does not directly inhibit tyrosinase but inhibits the expression of MITF (microphthalmia-associated transcription factor) by activating ERK (extracellular signal-regulated kinase) in melanin chromatocytes to give whitening effect. So, the melanin biosynthesis inhibiting effect of the compound is much greater than that of any other conventional inhibitors, and further the effect can be raised when the compound is used together with other inhibitors, owing to their different mechanisms. Thus, the compound of the present invention can be effectively used as a skin trouble treating agent, a skin whitening agent and a browning inhibitor.
Abstract:
Disclosed is a liquid crystal panel having a dual column spacer and a manufacturing method thereof. The liquid crystal panel includes a first substrate on which a polished organic insulation film is formed on the entire surface of a pixel region including a TFT. The first substrate includes a contact hole formed through the organic insulation film; a second substrate disposed opposite to the first substrate and having a black matrix and a color filter; a first column spacer formed on the second substrate to contact the first substrate to maintain a gap between the first substrate and the second substrate; and a second column spacer formed on the second substrate on an area of the second substrate corresponding to the contact hole on the first substrate. The second column spacer is separated from the first substrate by a predetermined distance.
