  • An ontology consists of a set and definition of concepts that represents the characteristics of a given domain and relationship between the elements. To reduce time-consuming and cost in building ontology, this paper proposes a semiautomatic method to build a domain ontology using the results of text analysis. To do this, we Propose a terminology processing method and use the extracted concepts and semantic relations between them to build ontology. An experiment domain is selected by the pharmacy field and the built ontology is applied to document retrieval. In order to represent usefulness for retrieving a document using the hierarchical relations in ontology, we compared a typical keyword based retrieval method with an ontology based retrieval method, which uses related information in an ontology for a related feedback. As a result, the latter shows the improvement of precision and recall by $4.97\%$ and $0.78\%$ respectively.

  • The paper aims to study how to describe the rigorous position on which semantic elements are laid, within the visual space. This purpose is, first of all, for the construction of visual syntactical semantics of the visual space. For this aim, the preliminary research begins with some definitions on : 1) visual space, visual design, visual syntactical semantic meaning, 2) position, sequence of position, 2-dim. sequence of position, and 3) 2-dim. numerical series of position, harmonious dynamic values. Here, The main issue is to define the position in general. To solve this problem, the researcher surveyed the positions on which the sets of pixemes are set up. The results are as follows ; 1. As far as the positions in visual space are concerned, they are the possible locations permitted in the visual patches. They are not the factual but the possible positions. 2.The position value that the sequential point has is not arithmetical but harmonious-dynamic, for it is not permitted for its own sake, but for the person, that is to say, for the viewer's visual perception. 3. The harmonious-dynamic value of positional sequence can be composed of the 2-dimensional successive numerical series which is, in turn, composed of the primordial 3 values x0, $\mu0$, y0. Here, the $\mu0$ is the harmonious mean value of x0 and y0. The x0 and y0 are, therefore, of the mutual dynamic relationship. 4. From this, the 2-dim general $\Delta-TABLE$ of the numerical series of position in visual design could be acquired through development of the primordial 3 values into the $X_i,\;Y_i$, orbit values.

  • Ontology is the artifacts for representing the truth or the states of objects by defining objects and their relations. In this paper, we propose an agent that classifies Web documents and provides personalized information towards user`s information needs using ontology. the agent uses ontology in which semantic relations on Web documents are represented in ta hierarchical form to classify Web documents. In this paper, ontology consists of concepts, features(describing concepts), relations(among concepts) and constraints(among elements in a feature). The agent can capture user's information needs efficiently by using ontology and assist Web navigation by using users profiles and the results of identification of semantic relations in Web documents. Also, the agent obtains Web documents by a look-ahead search and represents them as concepts, therefore users can understand them easily by receiving recommendations expressed in the form of high-level concepts.

  • This study describes the semantic theoretic interpretation through the extensive use of semantic metaphors for intensive web interface with information and the metaphoric value of metaphors for interface design. Common factors that influence web design are empirical establishment and verification for generating web symbols and these are have important elemental perspectives that are used to assess the usefulness and key elements of the site. In addition, the structure of the screen has begun to change dynamically from the application of web technological functions, and the media functions have become important to make web standards when implementing visual structuring from the perspective of semiotic. Instead of using a technical expression approach to examine semiotic, a semiotic approach is applied to create aesthetic codes through the human-computer interface in terms of semiotic in a variety of natural and universal fields. Based on this, it is used as means of communication to convey the intended meaning to users so as to highlight the importance of the usability issues and metaphors user interface.

  • The main goal of this paper is to describe and analyse intensifiers, especially non-head-bound-intensifiers (NHBIs), which can be included in the discussion and analysis of these elements as focus particles. In doing so, NHBIs such as Korean susulo, casin/cache, English x-self and German selbst are dealt with in a rather cross-linguistical perspective. The pure and strict comparison between Korean, English and German is not intended. This paper is mainly concerned with the semantic domain where the respective contributions of the expressions in question overlap, which offers the common base for the discussion regarding Korean, one of the non-European languages and English and German, two European languages. They share the semantic domain ‘intensification’ regarding relevant subject-NP. They introduce an ordering distinguishing center and periphery. In contrast to head-bound-intensifiers (HBIs), however, NHBIs add self-involvement (directness of involvement) of subject-NP to the meaning of the relevant sentence. I adopt the proposals of Konig (1991), Primus (1992) and Siemund (2000) in the treatment of intensifiers as focus particles. However, I reject Konig (1991) that just NHBIs talre scope over a whole clause, Primus (1992) that NHBIs focus VPs, not NPs, and Siemund (2000) that NHBIs can be further devided into two groups, viz. NHBIs with exclusive readings and NHBIs with inclusive readings. Evidence for my position is presented mainly in the course of describing and analysing some syntactic properties and the meaning and use of NHBIs. I come to the conclusion that both the common meaning of intensifiers as focus particles and the common meaning of NHBIs of three languages can be represented by a simple logical formalism.

  • With respect to the Semantic Web proposed to overcome the limitation of the Web, OWL has been recommended as the ontology language used to give a well-defined meaning to diverse data. OWL is the representative ontology language suggested by W3C. An efficient retrieval of OWL data requires a well-constructed storage schema. In this paper, we propose a storage schema construction technique which supports more efficient query processing. A retrieval technique corresponding to the proposed storage schema is also introduced. OWL data includes inheritance information of classes and properties. When OWL data is extracted, hierarchy information should be considered. For this reason, an additional XML document is created to preserve hierarchy information and stored in an XML database system. An existing numbering scheme is utilized to extract ancestor/descendent relationships, and order information of nodes is added as attribute values of elements in an XML document. Thus, it is possible to retrieve subclasses and subproperties fast and easily. The improved query performance from experiments shows the effectiveness of the proposed storage schema construction and retrieval method.

  • Recently, many researches have been conducted to solve data heterogeneity as a way for data integration. The elements of the system that we suggest are an XMDR wrapper and XMDR Repository. XMDR wrapper solves the heterogeneity of the existing system by creating the interface based on the standard information of XMDR, and performing the inter-conversion between global XMDR query and local query using mapping data on standard information and local schema. XMDR Repository are composed of XMDR which manages the mapping data on standard information and local schema, and of Proxy DB which saves the accomplished results. With XMDR wrapper and XMDR Repository, users can use the same interface, and they need not conduct repeated queries since XMDR wrapper not only solves the heterogeneity of the schema using the meta-semantic ontology of XMDR, but also considers the heterogeneity accompanying the meaning of the value through instance semantic ontology. Therefore, in this paper we suggest the grid wrapper for the solution of data heterogeneity and efficient data integration.

  • This study aims to investigate language society cultural aspects in a community, examining and comparing linguistic errors of English signboards (ES) at home and abroad. The data comprised the ES in 5 cities, Korea and in Paris, France. The findings showed that the errors of the ES in Korea reached to 39.2%, whereas those in Paris contained 24.7%. In Korea, ES and errors were the most in Myeong-dong area. In Paris, the most ES were in the area of Eiffel Tower, but the most linguistic errors appeared at the 3, 4 districts of Marais. Those errors belonged to most in the business of drink, food, and clothes in turn in Korea, while this was the case in the field of clothes, food, and culture in Paris. The frequent errors were classified into semantic, morphologic, and syntactic aspects in turn. The regulations on signboards of foreign languages existed but were not abided by in the both countries. Thus, more practical and reasonable devices and policies are required to establish a more harmonious atmosphere of the ES.

  • Video information retrieval has become a very important issue because of the explosive increase in video data from Web content development. Meanwhile, content-based video analysis using visual features has been the main source for video information retrieval and browsing. Content in video can be represented with content-based analysis techniques, which can extract various features from audio-visual data such as frames, shots, colors, texture, or shape. Moreover, similarity between videos can be measured through content-based analysis. However, a movie that is one of typical types of video data is organized by story as well as audio-visual data. This causes a semantic gap between significant information recognized by people and information resulting from content-based analysis, when content-based video analysis using only audio-visual data of low level is applied to information retrieval of movie. The reason for this semantic gap is that the story line for a movie is high level information, with relationships in the content that changes as the movie progresses. Information retrieval related to the story line of a movie cannot be executed by only content-based analysis techniques. A formal model is needed, which can determine relationships among movie contents, or track meaning changes, in order to accurately retrieve the story information. Recently, story-based video analysis techniques have emerged using a social network concept for story information retrieval. These approaches represent a story by using the relationships between characters in a movie, but these approaches have problems. First, they do not express dynamic changes in relationships between characters according to story development. Second, they miss profound information, such as emotions indicating the identities and psychological states of the characters. Emotion is essential to understanding a character's motivation, conflict, and resolution. Third, they do not take account of events and background that contribute to the story. As a result, this paper reviews the importance and weaknesses of previous video analysis methods ranging from content-based approaches to story analysis based on social network. Also, we suggest necessary elements, such as character, background, and events, based on narrative structures introduced in the literature. We extract characters' emotional words from the script of the movie Pretty Woman by using the hierarchical attribute of WordNet, which is an extensive English thesaurus. WordNet offers relationships between words (e.g., synonyms, hypernyms, hyponyms, antonyms). We present a method to visualize the emotional pattern of a character over time. Second, a character's inner nature must be predetermined in order to model a character arc that can depict the character's growth and development. To this end, we analyze the amount of the character's dialogue in the script and track the character's inner nature using social network concepts, such as in-degree (incoming links) and out-degree (outgoing links). Additionally, we propose a method that can track a character's inner nature by tracing indices such as degree, in-degree, and out-degree of the character network in a movie through its progression. Finally, the spatial background where characters meet and where events take place is an important element in the story. We take advantage of the movie script to extracting significant spatial background and suggest a scene map describing spatial arrangements and distances in the movie. Important places where main characters first meet or where they stay during long periods of time can be extracted through this scene map. In view of the aforementioned three elements (character, event, background), we extract a variety of information related to the story and evaluate the performance of the proposed method. We can track story information extracted over time and detect a change in the character's emotion or inner nature, spatial movement, and conflicts and resolutions in the story.
