As shown in Wikipedia, tagging or cross-linking through major keywords in a document collection improves not only the readability of documents but also responsive and adaptive navigation among related documents. In recent years, the Semantic Web has increased the importance of social tagging as a key feature of the Web 2.0 and, as its crucial phenotype, Tag Cloud has emerged to the public. In this paper we provide an efficient method of automated in-text keyword tagging based on large-scale controlled term collection or keyword dictionary, where the computational complexity of O(mN) - if a pattern matching algorithm is used - can be reduced to O(mlogN) - if an Information Retrieval technique is adopted - while m is the length of target document and N is the total number of candidate terms to be tagged. The result shows that automatic in-text tagging with keywords filtered by Information Retrieval speeds up to about 6 $\sim$ 40 times compared with the fastest pattern matching algorithm.

Precision correction is the process of geometrically aligning images to a reference coordinate system using GCPs(Ground Control Points). Many applications of remote sensing data, such as change detection, mapping and environmental monitoring, rely on the accuracy of precision correction. However it is a very time consuming and laborious process. It requires GCP collection, the identification of image points and their corresponding reference coordinates. At typical satellite ground stations, GCP collection requires most of man-powers in processing satellite images. A method of automatic registration of satellite images is demanding. In this paper, we propose a new algorithm for automatic precision correction by GCP chips and RANSAC(Random Sample Consensus). The algorithm is divided into two major steps. The first one is the automated generation of ground control points. An automated stereo matching based on normalized cross correlation will be used. We have improved the accuracy of stereo matching by determining the size and shape of match windows according to incidence angle and scene orientation from ancillary data. The second one is the robust estimation of mapping function from control points. We used the RANSAC algorithm for this step and effectively removed the outliers of matching results. We carried out experiments with SPOT images over three test sites which were taken at different time and look-angle with each other. Left image was used to select UP chipsets and right image to match against GCP chipsets and perform automatic registration. In result, we could show that our approach of automated matching and robust estimation worked well for automated registration.

This study analyzed features in contemporary men's collection to provide data for characteristics of kitsch in men's collection. The research method was to see background of the concept of kitsch through the domestic and international publications, the Internet, paper. Five designers' collections that have characteristics of kitsch were selected. The range of collection is from the 2000 S/S to 2011 F/W in Men's collection. The results are as follows: kitsch characteristics could be classified by amusements, inappropriateness, satire. First, exaggerative amusements in men's collection appeared exaggerated form, large size, which is ridiculous at the same time. Infantile amusements represents the image of a pure concentric matching accessories such as toys to the children express. sensual amusements reveals the sexual instincts and desires and people can feel satisfaction through sensual amusements. Second, inappropriateness is characteristic of kitsch to escape from normal life. Clothing does not fit the body and destroyed the design or design of this feature appears. It looks clumsy and strange. Inappropriateness characteristic in men's collection can be divided into inadequate performance and sexual inappropriateness. Third, satire can be divided into resistant satire, imitative satire, and popular satire. Resistance satire with anti-social tendencies through their clothing is achieved by expressing their needs. It was affected by sub-culture like Hippie or Punk. Imitative satire is to imitate other culture, customs and race. It is to resolve complaints through the consumption of things in disparities of wealth and materialism in the society. Popular satire is to express emotions that are free using materials that can recycling like can, bottle or paper.

As the role of information collection becomes increasingly important in the enormous data environment, there is growing demand for more intelligent information technologies for managing complex data. On the other hand, it is difficult to find a solution because of the data complexity and big scaled amount. Accordingly, there is a need for a special intelligent knowledge base frame that can be operated by itself flexibly. In this paper, by adopting switching function for signal transmission in the synapse of the human brain, I/E selective activation based knowledge reconfiguring mechanism is proposed for building more intelligent information management system. In particular, knowledge network design, a special knowledge node structure, Type definition, I/E gauge definition and I/E matching scheme are provided. Using these concepts, the proposed system makes the functions of activation by I/E Gauge, selection and reconfiguration. In a more efficient manner, the routing and reasoning process was performed based on the knowledge reconfiguration network. In the experiments, the process of selection by I/E matching, knowledge reconfiguration and routing & reasoning results are described.

Geometric correction is a critical step to remove geometric distortions in satellite images. For correct geometric correction, Ground Control Points (GCPs) have to be chosen carefully to guarantee the quality of corrected satellite images. In this paper, we present an automatic approach for geometric correction by constructing GCP Chip database (GCP DB) that is a collection of pieces of images with geometric information. The GCP DB is constructed by exploiting Landsat's nadir-viewing property and the constructed GCP DB is combined with a simple block matching algorithm for efficient GCP matching. This approach reduces time and energy for tedious manual geometric correction and promotes usage of Landsat images.

With the growing usage of the networks, the world-wide Internet has become the main means to exchange data and carry out transactions. It has also become the main means to attack hosts. To solve the security problems which occur in the network such as Internet, we import software products of network security elements like an IDS (Intrusion Detection System) and a firewall. In this paper, we have designed and constructed the general simulation environment of network security model composed of multiple IDSes and a firewall which coordinate by CNP (Contract Net Protocol) for the effective detection of the intrusion. The CNP, the methodology for efficient integration of computer systems on heterogeneous environment such as distributed systems, is essentially a collection of agents, which cooperate to resolve a problem. Command console in the CNP is a manager who controls the execution of agents or a contractee, who performs intrusion detection. In the network security model, each model of simulation environment is hierarchically designed by DEVS(Discrete Event system Specification) formalism. The purpose of this simulation is that the application of rete pattern-matching algorithm speeds up the inference cycle phases of the intrusion detection expert system and we evaluate the characteristics and performance of CNP architecture with rete pattern-matching algorithm.

A time-series data is the collection of real numbers over the time intervals. One of the main tasks in time-series data is efficiently to find subsequences similar to a given query sequence. In this paper, we propose an efficient subsequence matching method, which is called Instance-Match (I-Match). I-Match constructs a virtual window in order to reduce false alarms. Through the experiment with real data set and query sets, we show that I-Match improves query processing time by up to 2.95 times and significantly reduces the number of candidates comparing to Dual Match.

This Study looks into increase of Match-ending type of 'Ureonggaksi' folktale and its secularization focusing on Match-ending types of 71 materials from "The Comprehensive Collection of Korean Folklore"(1979-1985) and 'The Revision And Enlargement project' (2008-2018). This study classifies 'Ureonggaksi' folktale into ones of 1910-70s, 80s, and 2000s. Match-ending types increase in "The Comprehensive Collection of Korean Folklore" and 'The Revision And Enlargement project'. Match-ending types constitute 60% of Ureonggaksi' folktale materials from "The Comprehensive Collection of Korean Folklore" and 'The Revision And Enlargement project', which is twice more than 34% of Parting-ending types. Firstly, taboo motif in Match-ending types is inclined to disappear. Even if taboo motif appears, materials with keeping its taboo are more than breaking one. It means that the function of taboo weakens, since the meaning of sacred wedding is emphasized when it is broken. Desacralization of Ureonggaksi figure is inclined to make the match of hero and heroin recognized as a common one. Increase of match type without taboo motif, and a new Ureonggaksi type in 'The Revision And Enlargement project', Underground monster-defeating type, with a character of Romantic matching narrative, mean Discoloration of Ureonggaksi folktale. Interest and recognition on sacred existence disappears, and there is found the conciousness to pursue happiness in real world through connection between man and woman by realistic world-view. This study contains 37 Ureonggaksi folktales recorded in 'The Revision And Enlargement project' (2008-2018) as material. Furthermore, there are found new Ureonggaksi types in 'The Revision And Enlargement project': Underground monster-defeating type, which is transformed from groom with bird-feather clothes type(a kind of matching-ending type of Ureonggaksi folktale), and the subjugated's resistance awareness weakens and shows a character of Romantic matching narrative.
