Component-Based Development(CBD) leverages software reusability and diminishes development costs. Various works about component models, such as EJB, COM, and CCM are in progress to support CBD. However, current component models hardly support flexible assembly of pre-built components. To cope with this problem, architecture for component assembly must be defined in the abstract level and the gap between system architecture and its implementation should be diminished in the implementation level. This paper proposes a method for architecture-based design and implementation of component assembly. Architecture is described by the ADL, and the tool, COBALT Assembler, is introduced to support the proposed design and implementation phase of component assembly.

This paper proposes a convolution tree kernel-based approach for relation extraction where the parse tree is expanded with entity features such as entity type, subtype, and mention level etc. Our study indicates that not only can our method effectively capture both syntactic structure and entity information of relation instances, but also can avoid the difficulty with tuning the parameters in composite kernels. We also demonstrate that predicate verb information can be used to further improve the performance, though its enhancement is limited. Evaluation on the ACE2004 benchmark corpus shows that our system slightly outperforms both the previous best-reported feature-based and kernel-based systems.

This paper presents a study on the introduction of User Model-Based Dialogue System. Also we present a plan-based Korean dialogue system as a natural language database user interface for product search. The system can be characterized by its support for mixed initiative to give user more control over dialogue, employment of user model to reflect user's preferences, alternative solution suggestion if there is no product matched exactly to user's requirements, handling circumlocution which frequently occurs in dialogues. The user modeling shell system BGP-MS is adapted for the system. The system provides for a user-friendly database user interface by managing dialogue intelligently. By its implementation and test, it has been shown that the user model-based dialogue system can be utilized effectively for product search.

It has experienced how difficult People with foreign language learning, it is to pronounce a new language different from the native language. The goal of various foreigners who want to learn Korean is to speak Korean as well as their native language to communicate smoothly. However, each native language's vocal habits also appear in Korean pronunciation, which prevents accurate information transmission. In this paper, the pronunciation of Chinese learners was compared with that of Korean. For comparison, the fundamental frequency and its variation of the speech signal were examined and the spectrogram was analyzed. The Formant frequencies known as the resonant frequency of the vocal tract were calculated. Based on these characteristics parameters, the classifier of the Supporting Vector Machine was found to classify the pronunciation of Koreans and the pronunciation of Chinese learners. In particular, the linguistic proposition was scientifically proved by examining the Korean pronunciation of /ㄹ/ that the Chinese people were not good at pronouncing.

Under the textbook-driven approach to English education in the Korean selling, the importance of the English textbook can not be overemphasized as the main source of learning materials. Recently, with the development of computer-based language corpora, the recognition of the importance of collocations and the availability of computerized databases of words have caused a resurgence and facilitation in the instruction of collocation. The primary purpose of the present study is to identify the characteristics of lexical collocation and the extent of its use in high school 10th-grade textbooks. From all the analyses, it is revealed that the language materials reflect various constructed collocation in the case of adjective+noun and noun+noun collocations in a natural context. However, verb+noun and adverb+verb collocations are not fully reflected. This is true for delexicalized verbs, and verb and adjective intensifiers. Also the language materials do not provide sufficient support for the lexical syllabus, even though all textbooks may be somewhat adequate in terms of vocabulary size. Finally, based on the analyses of the texts, the suggestions for English collocation instruction are made in the lexical approach.

XML is the standard for storing and exchanging information in the Web. As the applications of XML become more widespread, the worts on rule-based technology are rapidly going on to support reactive functionality on the XML documents and the XML repositories. Active rules consist of event-condition-action, which automatically perform actions in response to status change of database. Therefore the feature of active rule satisfies the new needs in XML setting. In this paper, we propose not only a XML based active rule language to manage XML document automatically, but also an active rule analysis method to guarantee rule termination. Finally, we demonstrate some examples of active rule defined by the proposed rule language, and also verify the efficiency of our analysis method by comparing with another method.

Importance of coordination among heterogeneous devices is significantly increasing to meet the challenges presented by the evolvement of the ubiquitous computing environment. The web services technology is going up as a promising solution to support the inter-operability between such heterogeneous devices via well-defined protocol. Currently, ECA(Event-Condition-Action) rule based framework for coordinating devices is proposed, it is called as WS-ECA(Web Services-ECA) framework. This framework was basically based on the web services and proposed the ECA based rule language, And this also proposed the framework that could enable the device coordination based on proposed rule language. In this paper, we propose the protocol among the components of WS-ECA framework to support dynamic feature for ubiquitous environment, and we also propose WSDL extension to support service and event descriptions these are provided in components of this framework.

This thesis is based on an in-depth interview on participation experience of ten immigrants who reside in S Multi-cultural Family Support Center that is located in Gyeonggi-do in Korea Immigration & Integration Program(KIIP). The purpose of this research is to present through it's basic data for improvement in the operation of KIIP in the future by grasping participation process in KIIP that the immigrants have experienced, problems involved in their operation, and related requirements. Major results of the research are as follows: First, the motive for the immigrants' participation in KIIP was to acquire Korean nationality, learn Korean, and prepare for their future in Korea. Second, as a difficulty in participation in KIIP, access to educational institutions loomed large. Third, regarding improvements in the operation of KIIP, marriage immigrants needed to continue Korean language education, whereas other immigrants revealed a demand for opening evening classes or weekend classes. In the final analysis, it seems that for KIIP to provide an opportunity for the immigrants to have a vision for their life in the future, as well as for its realization in Korean society, policy-oriented institutional support that pays attention to their life situation and demands is badly needed.

The purpose of this study was to find the effects and problems in the support projects in multicultural family support centers and to present suggestions for its improvement. For this purpose, 10 specialists in 3 multicultural family support centers in Daegu, who organize and operate projects for female immigrants and their families, were interviewed via focus groups and then interviewed in-depth. The major findings were as follows: 1) the effect of the support projects was an increase in participation and concern of female immigrants and their families; 2)problems of the support projects included lack of flexibility of the projects, and overlap of projects among centers. 3)The results of the study suggest improved operation by extending the support networks to other support centers and facilities within the community, increasing the individualized programs based on their specialties, and promoting integrated projects (such as combining language courses and cultural programs, family-support programs and cultural events). Further studies will be extend to find out model cases from support projects of several centers, expand them to other centers, and verify its effects on operating projects.

In this paper, two new approaches to align English-Arabic sentences in bilingual parallel corpora based on the Multi-Class Support Vector Machine (MSVM) and the Hidden Markov Model (HMM) classifiers are presented. A feature vector is extracted from the text pair that is under consideration. This vector contains text features such as length, punctuation score, and cognate score values. A set of manually prepared training data was assigned to train the Multi-Class Support Vector Machine and Hidden Markov Model. Another set of data was used for testing. The results of the MSVM and HMM outperform the results of the length based approach. Moreover these new approaches are valid for any language pairs and are quite flexible since the feature vector may contain less, more, or different features, such as a lexical matching feature and Hanzi characters in Japanese-Chinese texts, than the ones used in the current research.
