화행 분석이란 자연언어로 된 발화를 통해서 나타나는 화자의 의도를 인식하는 것으로 대화를 처리하는 여러 응용 분야에서 중요하게 요구되는 과정이다. 기존의 연구에서는 이전 발화의 화행과 현재 발화의 문장 자질을 사용하여 규칙 기반 및 통계 기반의 연구가 진행되었다. 하지만 본 논문에서는 현재 발화 이후의 후보 화행을 추정하여 이를 현재 발화의 화행을 결정하는데 사용함으로써 기존의 연구와 차별화를 두었으며, 실제로 기존 방법보다 약 4%의 성능향상을 보인 96.08%의 정확도(accuracy)를 보였다. 또한 이전 발화의 화행 정보 대신 이전 화행을 결정하는데 사용했던 문장 자질을 현재 발화의 화행 결정에 직접 사용함으로써 실제 이전 화행을 적용했을 때보다 향상된 성능을 가져왔으며, 이전 문장 자질과 후보 화행을 함께 사용하여 화행을 결정했을 경우 96.96%의 정확도를 보였다.

Architect Bernard Tschumi had explored a new architectural conception through his own notional devices such as space, event and movement during 1970s. But, among these notions, the concept of movement was ambiguous and difficult to adopt it for architectural design strategy. Because the movements in everyday's behaviour or in dancing art are significantly different from architectural thought. However he had succeeded in coining the creative notion of movement as almost real body's and of living flesh. He invented an acute methodology and bold interpretation for his early experimental works. So, this paper tried to understand and analyse his concept of movement focused on his early works. The results of this paper's discussion are as follows; First, Tschumi's movement concept Is dynamic one operated by desire and can violate space in physical level as well as metaphysical level. Next, the movement performs the role of generator which deforms space or even generate it. Third, his movement can be readable only when you go down and bring it in practice. Also it Is unblocked potentiality, undetermined sequential material and unfinished practice. Fourth, when Tschumi's movement could be thought as walking, this walking movement makes up a story through rhetorical speech acts that are presented by turns and detours.

This paper represents the mobile robot control system remote controlled by PDA(personal digital assistance). So far, owing to the development of internet technologies, lots of remote control methods through internet have been proposed. To control a mobile robot through internet and guide it under unknown environment, We propose a control method activated by PDA. In a proposed system, PDA acts as a user interface to communicate with notebook as a controller of the mobile robot system using TCP/IP protocol, and the notebook controls the mobile robot system. The information about the direction and velocity of the mobile robot feedbacks to the PDA and the PDA send new control method produced from the fuzzy inference engine.

This paper is aimed at the investigation of pragmatic contributions to the identification of explicatures. An explicature is the result of fleshing out the semantic representation of an utterance. The basic assumption of the paper is that the process of the developing the semantic representation into an explicature depends heavily on contextual information. Therefore, we are concerned with the way in which hearers use contextual information to flesh rut or develop the semantic representation of an utterance. The identification of explicatures includes both the recovery of the proposition expressed and the recovery of what we called higher-level explicatures. There are three subtasks involved in the recovery of the proposition expressed: reference assignment disambiguation and enrichment On the other hand, there are two subtasks involved in the recovery of higher-level explicatures: attitudes and speech acts.

목적 지향 대화에서, 사용자의 의도는 화행(speech acts)과 개념열(concept sequences)로 나타낼 수 있다. 화행은 대화의 영역과는 상관없이 표현되는 정보이고, 개념열은 영역과 깊은 관련을 지닌 정보이다. 대화시스템에서 화행과 개념열로 구성되는 사용자의 의도를 정확히 파악하는 것은 시스템이 사용자의 발화에 정확히 응대하는 데에 매우 중요하다. 본 논문에서는 일정관리 영역에서의 대화를 대상으로 화행과 개념열을 분류하고 신경망을 사용하여 이들을 분석한다. 화행과 개념열로 구성되는 의도 분석에 사용하는 자질은 크게 문맥 자질과 문장 자질로 분류되며, 문장자질은 카이제곱 통계량을 사용하여 사용자의 의도 분석에 효과적인 자질만을 선택하여 사용하고 문맥자질로는 이전 발화에 대한 정보를 활용한다. 신경망을 사용하여 사용자 의도 분석을 수행한 결과 성능이 우수함을 알 수 있었다.

The objective of this research is to develop a formal framework and methodology to facilitate real-time data integration, thus enabling semantic interoperability among distributed and heterogeneous information systems. The proposed approach is based on the concepts of "ontology" and "semantic mediators." An ontology is developed and used to capture the intension (including structure, integrity rules and meta-properties) of the database schema. We also develop the agent communication protocol for semantic reconciliation, which is based on the theory of speech acts and agent communication language. This protocol is used by a set of semantic mediators, which automatically detect and resolve various semantic conflicts at the data- and schema-levels by referring to the ontology. A mediation-based query processing technique is developed to provide uniform and integrated access to the multiple heterogeneous information sources. Prototype tools are being implemented to provide proof of concept for this work.

Purpose: The purpose of this study was to describe and to analyze real conversation about polite behavior of nurses in cancer units. Methods: This study was conducted using a Brown & Levinson(1987) theory to analyze the polite behavior of nurses in cancer units. Five nurses who participated in this research gave permission to be videotaped. The data was collected from January to February, 2006. Results: Polite behavior of nurses in cancer units consisted of greetings, emotional support, open questions and indirect direction. And impolite behavior of nurses in cancer units was using the medical terminology, repetition of direct speech acts and task-oriented conversation. Conclusion: This study suggests polite behavior strategies for effective nursing conversation with cancer patients. Therefore, the findings may provide basic raw materials for educational programmes and intervention studies.

This paper proposes an algorithm for analyzing illocutionary force type (IfT)s in a dialogue, based on the context and modal information in the ending of a word. In korean, the variation of an illocutionary force type that represents a speaker's intention frequently occurs at the ending of a word, according to the type of modal information. And in an analysis of speech acts, the modal information illocutionary force types. In this paper, we analyze real dialogue dta, classify the types of illocutionary forces, perform the manual tagging of IFTs and show the freqency of each IFT's occurence. And we also propose an algorithm to extract IFTs, based on the relationship between the analyzed IFTs and the endings of a word. And we use this proposed algorithm to make an experiment on dialogue data and show its efficiency.

This paper deals with the design and development of a real-time integrated communication architecture for heterarchical SFCS(Shop Floor Control System). In autonomous agent-based heterarchical SFCS, each functional unit of parts and resources is equipped with an intelligent controller (agent) that acts as the representative of the entity. The controllers communicate and negotiate with other controllers on a real-time basis through message passing and bidding protocol to achieve mutual agreements for task sharing. ICPL(Integrated Communication Protocol and Language) is proposed for this purpose. ICPL is a language and a protocol for supporting communication among intelligent controllers. Based on the speech act theory, this paper proposes a semantic description for ICPL that associates the description of the cognitive states of controllers with the use of language primitives (message_type). Semantics for the basic set of ICPL messages is described. Eventually, an ICPL-based communication architecture can provide the implementation of the distributed and heterarchical SFCS, and makes the intelligent controller transparent to the negotiation problem.

The purpose of this study is to analyze communication between school and parents using the "letters to the parents", in order to examine possible areas of improvement for enhancing educational opportunities and school life adjustment for children from multi-cultural families. The letters to the parents used in elementary schools were analysed through genre analysis specifically for this study. At first, the Korean language textbooks for married female immigrants were investigated to see how many letters to parents were included in them. Second, letters to parents were collected to research their structure and content. They were categorized by the text type according to functions and speech acts. It is expected that the results of this study will be helpful for the Korean language education of married female immigrants.
