As the volume and diversity of scientific resources grows, trend detection and analysis have become much more important issues. A variety of trend detection, characterization, evaluation and visualization methodologies have been introduced for various application domains. In this paper, we consider detection of temporal trends for topics using feature(More)
This paper presents an automatic mapping method among large-scale heterogeneous language resources: Sejong Semantic Classes (SJSC) and KorLex. KorLex is a large-scale Korean Word-Net, but it lacks specific syntactic & semantic information. Sejong Electronic Dictionary (SJD), of which semantic segmentation depends on SJSC, has much lower lexical coverage(More)
This paper presents an efficient parallel information retrieval (IR) system which provides fast information service for the Internet users on low-cost high-performance PC-NOW environment. The IR system is implemented on a PC cluster based on the Scalable Coherent Interface (SCI), a powerful interconnecting mechanism for both shared memory models and message(More)
We developed Cyber Forensics Ontology for the criminal investigation in cyber space. Cyber crime is classified into cyber terror and general cyber crime, and those two classes are connected with each other. The investigation of cyber terror requires high technology, system environment and experts, and general cyber crime is connected with general crime by(More)
This paper presents extended Relief algorithms and their use in instance-based feature filtering for document feature selection. The Relief algorithms are general and successful feature estimators that detect conditional dependencies of features between instances, and are applied in the preprocessing step for document classification and regression. Since(More)
The EPCglobal Network is a network providing a shared view of the disposition of EPC-bearing objects between EPCglobal subscribers, within a relevant business context. In the EPCglobal Network, product data is distributed to several EPCISes(EPC Information Services) via movement of the product. The ONS (Object Naming Service) and the EPCISDS (EPCIS(More)
We have proposed Auto-TAN, an automatic transcription system of Arabic numerals into Korean alphabetic letters using linguistic rules and clues. Few previous studies have previously discussed the problems in transcribing Arabic numerals into Korean text. We have suggested detailed NRF (number reading formula) paradigms, analyzed the structure of NUMEs(More)
Determining the situation within logistics process is a key goal of smart the professional logistical support research. Using ontology to model situation enables multiple entities to have common understanding of the situation during collaboration. In order to deliver relevant products at the right time to the right place, the event notification systems need(More)
This paper describes the implementation and performance of M-VIA on the AceNIC Gigabit Ethernet card. The AceNIC adapter has several notable hardware features for high-speed communication, such as jumbo frames and interrupt coalescing. The M-VIA performance characteristics were measured and evaluated based on these hardware features. Our results show that(More)
