In this paper, we present POSSDM (POSTECH Situation-Based Dialogue Manager) for a spoken dialogue system using a new example and situation-based dialogue management technique for effective generation of appropriate system responses. Spoken dialogue system should generate cooperative responses to smoothly control dialogue flow with the users. We introduce a new dialogue management technique incorporating dialogue examples and situation-based rules for EPG (Electronic Program Guide) domain. For the system response inference, we automatically construct and index a dialogue example database from dialogue corpus, and the best dialogue example is retrieved for a proper system response with the query from a dialogue situation including a current user utterance, dialogue act, and discourse history. When dialogue corpus is not enough to cover the domain, we also apply manually constructed situation-based rules mainly for meta-level dialogue management.

This paper presents a dialogue interface using the dialogue management system as a method for controlling home appliances in Home Network Services. In order to realize this type of dialogue interface, we first investigated the user requirements for Home Network Services by analyzing the dialogues entered by users. Based on the analysis, we were able to extract 15 user intentions and 22 semantic components. In our study, example dialogues were collected from WOZ (Wizard-of-OZ) environment to implement a reasoning model for generating meaningful responses for example-based dialogue modeling technique. An overview of the Home Network Control System using proposed dialogue interface will be presented. Lastly, we will show that the Dialogue Management System trained with our collected dialogues behaves properly to achieve its task of controlling Home Network appliances by going through the steps of natural language understanding, response reasoning, response generation.

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.

This paper presents a dialogue interface using the dialogue management system as a method for controlling home appliances in Home Network Services. In order to realize this type of dialogue interface, we annotated 96,000 utterance pair sized dialogue set and developed an example-based dialogue system. This paper introduces the automatic error correction module for the SMS-styled sentence. With this module we increase the accuracy of NLU(Natural Language Understanding) module. Our NLU module shows an accuracy of 86.2%, which is an improvement of 5.25% over than the baseline. The task completeness of the proposed SMS dialogue interface was 82%.

The purpose of this study is to investigate learner-learner dialogue during speaking tasks. In the Korean language classroom, conversation between learners is an important activity as speaking practice. However, learner dialogue is also a tool to enable learners to collaboratively conduct various cognitive activities in the classroom. In previous research, it was unfolded that through learner-learner dialogue, learners can solve second-language related problems and set a goal to carry out tasks. Therefore, this study analyzed learner-learner dialogue to investigate what kinds of cognitive activities are activated during the role-play task. As a result, the learners collaboratively generated and monitored language and content for role play. Also, in order to accomplish tasks more successfully, learners shared the same understanding about the goal of the task, and tried to manage the task procedure. Through learner-learner dialogue, learners can participate in cognitive activities such as content, language construction, and task management voluntarily without the help from teachers. This means that learner-learner dialogue can be an activity to support language learning tasks. Also, it can make learners actively involved in learning and by sharing resources with each other. It is also important that learners can experience language use that participates in real-world communication activities, such as learning in the classroom and collaborating with peer learners. This study is an exploratory study for a basic understanding of learner's conversation as a cognitive activity, and the scope of the study is limited to clarifying contents of learner-learner dialogue as a cognitive activity in speaking tasks. Based on the findings of this study, future research should be conducted on the function of learner-learner dialogue as a cognitive activity in Korean language learning and its role in the classroom of Korean language education.

미국과 유럽의 집회사워 관리정책은 지난 30년 동안 '물리력 의존 모델(Escalated Force Model)에서 협의관리모델 (Negotiated Management Model)로 급진적으로 변화해왔다. 스웨덴은 2008년부터 집회시위 주최 측과 대화를 통해 질서를 유지하는 '대화 경찰(Dialogue Police)' 제도를 시행하고 있다. 한국 경찰은 진압 위주의 대책을 탈피하기 위해 1999년 이무영 경찰청장이 제시한 '新(신)집회 시위 관리대책' 이후 2010년 G20 서울 정상회의를 전후해 협의관리모델의 한 방편인 '합법촉진적 집회사위 관리방침'(Facilitation of Lawful Protests Model)을 시행하고 있다. 이 방침을 바탕으로 G20 서울 정상회의를 무사히 치라낸 한국 경찰의 역량은 높이 평가할만한 것이다. 하지만 현국 경찰의 집회시위 관리정책에 대한 이론적 토대가 약하기 때문에, 이를 뒷받침하기 위해 서구 경찰의 협의관리모델을 통해 합법촉진적 집회시위관리방침을 분석하였다. 그중에서도 특히 집회시위 현장에서 시위대와 협상을 담당하는 스웨덴의 대화경찰과 한국의 정보경찰에 대해 비교해 보았다. 정보경찰이 집회시위에 대한 규제가 심각하다는 시각도 있지만, 시위대와 대화를 중단하는 경우는 없으며 최근 그 협의 사항이 잘 지켜지는 추세이기 때문에 한국적 협의관리모델이 나름대로 발달해 왔다고 볼 수 있는 것이다. 이에 대해 서울 G20 정상회담의 집회시위 관리정책을 관찰한 뉴욕시립대 Alex S. Vitale 교수는 한국 경찰도 '협의관리' 체계 속에서 운용되고 있다고 평가하고 있다. 한편, 한국과 서구의 경찰제도의 역사와 구조가 상이한데도, 대화, 협상, 조정촉진 대안제시와 같은 갈등해결기법을 연결고리로 집회시위 관리정책이 상호 접근하고 있다는 점에 주목해야 한다. 앞으로 갈등해결기법을 더 연구할 필요가 있으며, 한국적 집회시위 관리정책의 마래로 갈등해결 촉진모델(Facilitation of Conflict Resolution Model)을 제시하였다.

본 논문에서는 EPG 정보 검색을 위한 자연어 대화 시스템에 대해 논한다. 자연어 대화 시스템 구축을 위한, 대화 예제를 이용한 상황 기반 대화 관리 방법론은, 효율적이고 실용적인 대화 시스템 구축을 가능하게 한다. 대화 시스템은 사용자 발화에 대해 적합한 시스템 응답 발화를 출력하는 과정으로 진행되며, 이를 위해, 사용자 발화 의미 분석, 대화 관리, 시스템 응답 발화 생성의 과정을 거친다. 정확하고 신속한 정보의 전달이 중요한 EPG 정보 검색 도메인의 특성상 EPG 데이타베이스의 관리 및 갱신이 중요한 요소로 작용한다. 이를 위해 웹마이닝 기반의 EPG 데이타베이스 관리자를 구현함으로써 데이타베이스 구축에 필요한 비용을 최소화하고, 신속하고 정확한 정보를 제공할 수 있었다. 실험 결과를 통해 본 시스템이 EPG 정보 검색을 위해 적은 비용으로 높은 성능을 보이고 있음을 확인한다.
