Through advances driven by the Internet and the Smart Revolution, the amount and types of data generated by users have increased and diversified respectively. There is now a new concept at the center of attention, which is Big Data for assessing enormous amount of data and enjoying new values therefrom. In particular, efforts are required to analyze narratives within video clips and to study how to visualize such narratives in order to search contents stored in the Big Data. As part of the research efforts, this paper analyzes dialogues exchanged among characters and offers an interface named "Character-net" developed for modelling narratives. The interface Character-net can extract characters by analyzing narrative videos and also model the relationships between characters, both in the automatic manner. This signifies a possibility of a tool that can visualize a narrative based on an approach different from those used in existing studies. However, its drawbacks have been observed in terms of limited applications and difficulty in grasping a narrative's features at a glace. It was assumed that Character-net could be improved with the introduction of information design. Against the backdrop, the paper first provides a brief explanation of visualization design found in the data information design area and investigates research cases focused on the visualization of narratives present in videos. Next, key ideas of Character-net and its technical differences from existing studies have been introduced, followed by methods suggested for its potential improvements with the help of design-side solutions.

The development of digital technologies has changed the paradigm of an information-oriented society. Accordingly, the media-art and the net-art using digital media have been developed more interactively. Under the this influence, various experimental works using digital media are being produced and having a try to combination of art and digital on the network. In this paper, we looked into the relation between characteristics and playful of the net-art and analized the relation among interactive, network characteristics and intuitive play implemented on the net-art. Based upon these analyses, we intend to offer new aesthetic experiences through playful expression for humorous emotion on a traditional character, Dokkaebi.

When user wants to animate more than one character, some unexpected motion animation like a collision between characters may occur. Therefore, this problem must be resolved using a proper control mechanism. Therefore, this problem must be resolved using a proper control mechanism. This paper proposes an agent-based system that controls the motion animation of the character for representing animation scenario reflecting user\`s intention. This system provides a method that coordinates a type of motion and avoids collision between characters according to the moving path of a character in three-dimensional space. Agent communicates with others for motion synchronization. Agent is extended into several intelligent agents that coordinate character\`s motion. Agent system enables not only an intended motion animation, but also the scheduling of motion to an entire character animation. It designs automata model using Petri-net analysis tool for the agent\`s interaction as a method that passes the agent\`s information and infers the current state of agents. We implement this agent system to control the motion of character using agent technology and show an example of controlling the motion of human character model to prove the possiblity of motion control.

컴퓨터 게임에서의 인공지능은 규칙 기반 추론을 기반으로 한 추론 엔진을 사용하고 있다. 이 규칙 기반 주론 엔진은 비교적 간단하고 구현하기 쉽지만 규칙이 몇 가지 되지 않는다는 것과 규칙 변화가 없는 단점으로 게임 플레이어가 그 규칙들을 쉽게 알아버린다는 문제가 있다. 게임 제작자들은 이런 단점을 극복하고자 게임 플레이어끼리 경쟁을 붙이기 위해서 베틀 넷 등 네트워크 쪽으로 그 단점을 보안하려고 하고 있다. 하지만 오히려 네트워크로의 발전은 더욱 더 인간에 가까운 게임 캐릭터 인공지능을 요구하게 되었으며 규칙 기반 추론 방법으로는 이러한 요구를 충족할 수 없기 때문에 새로운 방법이 필요하게 된 것이다 이 논문에서는 그 새로운 방법에 대한 대척으로 신경망 알고리즘과 유전자 알고리즘을 사용한 인공생명 방법론으로 그 해결책을 모색하려 한다.

본 논문에서는 영화나 소설과 같은 콘텐츠의 스토리를 가시화해서 보여주는 시스템에 대해 제안하고 설명한다. 스토리를 가시화 해주기 위해 등장인물들 간의 관계를 모형화하는 Character-net 방법론을 채용하였고 스토리 진행에 따른 Character-net 변화를 분석하여 보여주는 시스템을 개발하였다. 시스템은 Character-net 변화 실행창과 등장인물 중심성 시계열 그래프 창으로 구성하였다. 두 개 창을 통해 스토리 차원의 검색이 가능토록 하였다. 본 논문에서는 스토리 가시화 시스템에 대해 설명하고 추가적으로 필요한 사항들에 대해 논의한다.

In this paper, we propose and describe the system to visualize the story of contents such as movies and novels. Character-net is applied as story model in order to visualize story. However, it is the form to be accumulated for total movie story, though it can depict the relationship between characters. We have developed the system that analyzes and shows the variation of Character-net and characters' tendency in order to represent story variation depending on movie progression. This system is composed by two windows that can play and analyze sequential Character-nets by time, and can analyze time variant graph of characters' degree centrality. First window has a function that supports to find important story points like the scenes that main characters appear or meet firstly. Second window supports a function that track each character's tendency or a variation of his tendency through analyzing in-degree graph and out-degree. This paper describes the proposed system and discusses additional requirements.

There are various approaches that retrieve information from video. However, previous approaches have considered just object information and relationship between objects without story information to retrieve contents. To retrieve exact information at video, we need analyzing approach based on characters and community since these are body of story proceeding. Therefore, this paper describes video information retrieval methodology based on character information. Characters progress story to form relationship through conversations. We can analyze the relationship between characters in a story with the methods that classifies role grades and clusters communities of characters. In this paper, for these, we propose the Character-net and describe how to classify role grades and cluster communities at Character-net. And we show this method to be efficient.

Recently, a number of researches related to video annotation and representation have been proposed to analyze video for searching and abstraction. In this paper, we have presented a method to provide the picture elements of conversational participants in video and the enhanced representation of the characters using those elements, collectively called Character-net. Because conversational participants are decided as characters detected in a script holding time, the previous Character-net suffers serious limitation that some listeners could not be detected as the participants. The participants who complete the story in video are very important factor to understand the context of the conversation. The picture elements for detecting the conversational participants consist of six elements as follows: subtitle, scene, the order of appearance, characters' eyes, patterns, and lip motion. In this paper, we present how to use those elements for detecting conversational participants and how to improve the representation of the Character-net. We can detect the conversational participants accurately when the proposed elements combine together and satisfy the special conditions. The experimental evaluation shows that the proposed method brings significant advantages in terms of both improving the detection of the conversational participants and enhancing the representation of Character-net.
