[en] EMOTIONS IN PLOTS WITH NON-DETERMINISTIC PLANNING FOR INTERACTIVE STORYTELLING / [pt] EMOÇÕES EM ENREDOS COM PLANEJAMENTO NÃO-DETERMINÍSTICO PARA NARRAÇÃO INTERATIVA

FABIO ARAUJO GUILHERME DA SILVA 25 April 2016 (has links)
[pt] Narração interativa é uma forma de entretenimento digital em que os usuários participam do processo de compor e dramatizar uma história. Nesse contexto, a determinação do comportamento dos personagens de acordo com as suas preferências individuais pode ser uma maneira interessante de gerar histórias plausíveis, onde os personagens agem de forma crível. Diversidade de histórias e oportunidades de interação são requisitos fundamentais a serem considerados ao se projetar tais aplicações. Esta tese propõe a criação de uma arquitetura e de um protótipo para a geração e dramatização de enredos interativos não determinísticos, utilizando um modelo de emoções que não só sirva para guiar as ações dos personagens apresentadas pelo algoritmo de geração de planos, mas que também influencie a participação dos usuários. Além disso, para melhorar a qualidade e nível de diversidade das histórias, os personagens devem ser capazes de evoluir em termos de seus traços de personalidade durante o desenrolar da trama, como um reflexo dos eventos que realizam ou a que são expostos. / [en] Interactive storytelling is a form of digital entertainment in which users participate in the process of composing and dramatizing a story. In this context, determining the characters behaviour according to their individual preferences can be an interesting way of generating plausible stories where the characters act in a believable manner. Diversity of stories and opportunities for interaction are key requirements to be considered when designing such applications. This thesis proposes the creation of an architecture and a prototype for the generation and dramatization of interactive nondeterministic plots, using a model of emotions that not only serves to guide the actions of the characters presented by the plan generation algorithm, but also influences the participation of the users. Also, to improve the quality and diversity level of the stories, characters must be able to evolve in terms of their personality traits as the plot unfolds, as a reflection of the events they perform or are exposed to.

Methodology to obtain the user's Human Values Scale from Smart User Models

Guzmán Obando, Javier 16 June 2008 (has links)
En años recientes,la Inteligencia Artificial ha contribuido a resolver problemas encontrados en el desempeño de las tareas de unidades informáticas, tanto si las computadoras están distribuidas para interactuar entre ellas o en cualquier entorno (Inteligencia Artificial Distribuida). Las Tecnologías de la Información permiten la creación de soluciones novedosas para problemas específicos mediante la aplicación de los hallazgos en diversas áreas de investigación. Nuestro trabajo está dirigido a la creación de modelos de usuario mediante un enfoque multidisciplinario en los cuales se emplean los principios de la psicología, inteligencia artificial distribuida, y el aprendizaje automático para crear modelos de usuario en entornos abiertos; uno de estos es la Inteligencia Ambiental basada en Modelos de Usuario con funciones de aprendizaje incremental y distribuido (conocidos como Smart User Model). Basándonos en estos modelos de usuario, dirigimos esta investigación a la adquisición de características del usuario importantes y que determinan la escala de valores dominantes de este en aquellos temas en los cuales está más interesado, desarrollando una metodología para obtener la Escala de Valores Humanos del usuario con respecto a sus características objetivas, subjetivas y emocionales (particularmente en Sistemas de Recomendación).Una de las áreas que ha sido poco investigada es la inclusión de la escala de valores humanos en los sistemas de información. Un Sistema de Recomendación, Modelo de usuario o Sistemas de Información, solo toman en cuenta las preferencias y emociones del usuario [Velásquez, 1996, 1997; Goldspink, 2000; Conte and Paolucci, 2001; Urban and Schmidt, 2001; Dal Forno and Merlone, 2001, 2002; Berkovsky et al., 2007c]. Por lo tanto, el principal enfoque de nuestra investigación está basado en la creación de una metodología que permita la generación de una escala de valores humanos para el usuario desde el modelo de usuario. Presentamos resultados obtenidos de un estudio de casos utilizando las características objetivas, subjetivas y emocionales en las áreas de servicios bancarios y de restaurantes donde la metodología propuesta en esta investigación fue puesta a prueba.En esta tesis, las principales contribuciones son: El desarrollo de una metodología que, dado un modelo de usuario con atributos objetivos, subjetivos y emocionales, se obtenga la Escala de Valores Humanos del usuario. La metodología propuesta está basada en el uso de aplicaciones ya existentes, donde todas las conexiones entre usuarios, agentes y dominios que se caracterizan por estas particularidades y atributos; por lo tanto, no se requiere de un esfuerzo extra por parte del usuario. / Information Technology enables new solutions to be created for specific problems by applying knowledge gained in various areas of research.Our work is aimed at creating user models using a multi-disciplinary approach in which we use principles of psychology, distributed artificial intelligence, and automatic learning to create user models in open environments; such as Environmental Intelligence based on User Models with functions of incremental and distributed learning (known as Smart User Models). Based on these user models, we aimed this research at acquiring user characteristics that are not trivial and that determine the user's scale of dominant values in the matters in which he/she is most interested, and developing a methodology for extracting the Human Values Scale of the user with regard to his/her objective, subjective, and emotional attributes (particularly in the Recommender Systems). One of the areas that have been little researched is the inclusion of the human values scale in information systems. A Recommender System, User Models, and Systems Information only takes into account the preferences and emotions of the user [Velásquez, 1996, 1997; Goldspink, 2000; Conte and Paolucci, 2001; Urban and Schmidt, 2001; Dal Forno and Merlone, 2001, 2002; Berkovsky et al., 2007c]. Therefore, the main approach of our research is based on creating a methodology that permits the generation of the human values scale of the user from the user model. We present results obtained from a case study using the objective, subjective, and emotional attributes in the banking and restaurant domains, where the methodology proposed in this research was tested. In this thesis, the main contributions are: To develop a methodology that, given a user model with objective, subjective and emotional attributes, obtains the user's Human Values Scale. The methodology proposed is based on the use of existing applications, where there are connections between users, agents, and domains that are characterised by their features and attributes; therefore, no extra effort is required by the user.
