Abstract: A knowledge representation expansion apparatus includes: a predicate-argument structure analyzing unit for extracting a predicate and at least one argument from a text using a meaning representation language; an ontology unit for representing knowledge using a knowledge representation language, which is a structured format understandable by a computer, and for extracting a second predicate corresponding to a first predicate, which is extracted from the predicate-argument structure analyzing unit; and a knowledge representation unit for representing knowledge extracted from the text using the first predicate, when the similarity of the first predicate and the second predicate is equal to or less than a threshold value.

Abstract: Disclosed is an SNS based auto schedule management service system that detects and extracts event information from SNS messages and records corresponding events in a personal schedule management system.

Abstract: Disclosed herein are a real-time semantic annotation system and a method of converting user-entered natural language strings into semantically-readable knowledge structure documents using the system in real time. The real-time semantic annotation system includes a natural language character string input device for enabling a user to enter natural language character strings, a character string pattern triplet-mapping table for storing natural language character string patterns and their corresponding triplets, a triplet extraction device for converting the entered natural language character strings into triplets by analyzing and processing the entered natural language character strings using the pattern-triplet mapping table, an alternative word recommendation device for providing notification that a user should enter an alternative word, and a machine-readable document generation device for generating machine-readable documents from the triplets using a semantically-readable knowledge structure.

Abstract: The present invention relates to an Internet-based information search apparatus for searching for information by accessing web resources through the Internet using both a method of representing the identifier of a web resource and the identifier. The Internet-based information search apparatus includes an ROAR name server for managing a resource name and a URL corresponding to the resource name, and transmitting URL information corresponding to contextual information, which contains the resource name, to a domain name server when the contextual information is received, the domain name server for receiving the URL information and then transmitting an IP address corresponding to the URL information to the ROAR name server; and an input module for receiving the contextual information, transmitting the contextual information to the ROAR name server through a web browser, receiving the IP address from the ROAR name server, and requesting corresponding information from a web server.

Abstract: Provided are a document classification method and a computer readable record medium having a program for executing the document classification method by a computer. The method for providing a classification code to a document, and classifying the document, includes a document indexing process of re-organizing contents of training documents using structure information of the training documents provided with classification codes, and generating an index list; a document retrieval process of searching the training documents for similar documents similar with an input document, using the index list; and a classification code generating process of generating a classification code list of the input document, using the classification codes of the similar documents.

Abstract: The method described herein provides for comparing a similarity between various phonetic transcriptions of a specific foreign word on the basis of an English pronunciation similarity comparison algorithm.

Abstract: A phonetic distance calculation method for similarity comparison between phonetic transcriptions of foreign words. A system manager defines character element transformation patterns occurrable between phonetic transcriptions derived from the same foreign language. A system generates new phonetic transcriptions according to the defined character element transformation patterns and assigns a demerit mark to each of the generated phonetic transcriptions according to a phonetic distance. A minimum phonetic distance between each of the generated phonetic transcriptions and a given phonetic transcription is calculated on the basis of a minimum edit distance calculation method. Any one of the generated phonetic transcriptions with a smallest one of the calculated minimum phonetic distances is determined to be most similar to the given phonetic transcription.

Abstract: Disclosed is a method of paying an electronic settlement in an electronic commerce by assigning a payment settlement agency between a payer and a payee. The method includes a first step of the payer obtaining an electronic catalog from the payee through Internet; a second step of the payer approving an access of a payer's bank account by a payment settlement agency server; a third step of the payer ordering goods to a payee server and paying a settlement through of the payment settlement agency; a fourth step of the payment settlement agency server providing confirmation of an effect of transaction between the payer and the payee to concerned parties of the transaction; and a fifth step of transferring a deposit from the payer's bank account to a payee's bank account through a financial network.
