In order to implement a dialogue system for Korean language tutoring, this paper aimed to describe a method of constructing a large amount of Korean task-oriented dialogue data using the Wizard-of-OZ method and a pedagogical feedback and evaluation method for Korean language errors made by foreign learners. The procedure for constructing a large amount of Korean task-oriented dialogue data consisted of three steps. The first step was the preparation step for the learner’s prior learning. The second step was related to a large Korean dialogue map constructed by Korean native speakers using the Wizard-of-OZ method. The third step was implementation of a Korean dialogue system based on the dialogue map. In educational feedback and evaluation, functions such as paraphrases, recommendation expressions, educational success rate, and error content evaluation by learner level were proposed. By means of the Wizard-of-OZ method, 3,253 Korean task-oriented dialogue data were established in four domains: restaurant, hotel, tourist attraction, and taxi. The dialogue system for Korean language tutoring is currently being implemented based on Korean taskoriented dialogue data. Ultimately, the task-oriented dialogue system for Korean language tutoring aims at an “augmentation of education” that collaborates with human teachers, not “teacher-less education” that replaces human teachers.

네트워크와 기술의 발전을 통해 도래한 가상세계는 월드와이드 웹의 새로운 방향으로 제시되고 있다. 가상세계는 필연적으로 다양한 스토리텔링을 창발해내는 장으로 역할하게 되는데 본 연구는 이때 가상세계에서 나타나는 서사구조를 기호학의 관점에서 살펴보고자 한다. 먼저 생활형 가상세계와 게임형 가상세계로 가상세계를 유형화하고 개발자 스토리텔링과 사용자 스토리텔링이라는 상대적 관점에서 가상세계의 서사구조를 살펴본다. 이를 통해 이들을 포괄할 수 있는 목적지향적 서사구조를 제시하고 기존 기호학의 이론을 통해 고찰해본다. 마지막으로 목적지향적 서사구조에 의해 형성되는 가상세계의 스토리텔링과 그 의의를 살펴본다.
