Modelação de diálogos com o Midiki: um gestor de diálogo do tipo Information State Update

Nesta dissertação investigamos a problemática da criação de sistemas e interfaces que permitam a interacção entre pessoas e máquinas através de linguagem natural(LN), recorrendo a Gestores de Diálogo (GD). Esse tipo de interacção concretiza-se através do estabelecimento de diálogos entre uma pessoa (cliente ou utilizador de um serviço) e a máquina, por exemplo, e em particular, através da fala. Quando disponibilizado da forma tradicional, o acesso ao serviço exige um intermediário Humano ou a adaptação da Pessoa a interfaces menos naturais, tais como linhas de comandos num computador, digitadas através de teclado ou o recurso (usual) a janelas, cliques de rato e preenchimento de formulários. Os sistemas que possibilitam a intermediação com esses serviços através de LN chamam-se Sistemas de Diálogo (SD), no núcleo dos quais se encontram os chamados Gestores de Diálogo. A implementação de SDs robustos ainda constitui um desafio, dada a complexidade, problemas e dificuldades que apresenta. Um SD, e em particular um GD, tem de ser configurado para levar a cabo um diálogo em linguagem natural com um Humano, por mais restrito ou mais genérico que seja o domínio (ou tarefa) considerado. Infelizmente, existem poucas metodologias e ferramentas de autoria que possibilitem a modelação fácil e intuitiva de tais diálogos (sobre os GDs). Nesta dissertação apresentamos uma metodologia [Quintal & Sampaio, 2007] e uma ferramenta para a autoria de diálogos com base no Gestor de Diálogo MIDIKI [Burke, 2005b]. A ferramenta de autoria automatiza as partes mais importantes da geração de código com vista à execução de um diálogo nesse GD.

Diversity Arrays: a solid state technology for sequence information independent genotyping

Here we present the successful application of the microarray technology platform to the analysis of DNA polymorphisms. Using the rice genome as a model, we demonstrate the potential of a high-throughput genome analysis method called Diversity Array Technology, DArT‘. In the format presented here the technology is assaying for the presence (or amount) of a specific DNA fragment in a representation derived from the total genomic DNA of an organism or a population of organisms. Two different approaches are presented: the first involves contrasting two representations on a single array while the second involves contrasting a representation with a reference DNA fragment common to all elements of the array. The Diversity Panels created using this method allow genetic fingerprinting of any organism or group of organisms belonging to the gene pool from which the panel was developed. Diversity Arrays enable rapid and economical application of a highly parallel, solid-state genotyping technology to any genome or complex genomic mixtures.

Library and Information Science Education and eScience: The Current State of ALA Accredited MLS/MLIS Programs in preparing Librarians and Information Professionals for eScience Needs

The purpose of this study is multifaceted: 1) to describe eScience research in acomprehensive way; 2) to help library and information specialists understand the realm of eScience research and the information needs of the community and demonstrate the importance of LIS professionals within the eScience domain; 3) and to explore the current state of curricular content of ALA accredited MLS/MLIS programs to understand the extent to which they prepare new professionals within eScience librarianship. The literature review focuses heavily on eScientists and other data-driven researchers’ information service needs in addition to demonstrating how and why librarians and information specialists can and should fulfill these service gaps and information needs within eScience research. By looking at the current curriculum of American Library Association (ALA) accredited MLS/MLIS programs, we can identify potential gaps in knowledge and where to improve in order to prepare and train new MLS/MLIS graduates to fulfill the needs of eScientists. This investigation is meant to be informative and can be used as a tool for LIS programs to assess their curriculums in comparison to the needs of eScience and other data-driven and networked research. Finally, this investigation will provide awareness and insight into the services needed to support a thriving eScience and data-driven research community to the LIS profession.
