É um campo interdisciplinar de pesquisa que visa a elaboração de modelos computacionais e mecanismos de tomada de decisões baseados nos processos neurobiológicos do cérebro, das ciências cognitivas e da psicologia para dotar os sistemas computacionais das faculdades de saber, pensar e sentir. O UCB-bot é uma aplicação utilizando o IBM Watson, visando responder perguntas sobre benefícios oferecidos pela Universidade Católica de Brasília (UCB) aos seus estudantes.

Research paper thumbnail of Collaborative Agents in Adaptative VLEs: Towards an Interface Agent for Interactivity and Decision-making Improvement

Working collaboratively in a multi-agent system, IAg receives notifications about situations that require interaction with students to assist and motivate them in the processes of navigation and use of VLE. In order to assist decision-making processes, it provides dashboards that enable the human tutor and VLE coordinators to make real-time decisions about non-normal situations. In addition, it monitors the actions of students seeking for clarifying doubts, utilizing a knowledge based on past situations. With this approach it is expected to enable a more attractive environment to students by reducing feelings of demotivation and isolation, and helping to reduce student dropout.

A systematic literature review on the concepts and the emergence of databases, information centers and observatories was conducted. The use of databases and information centers in transport and logistics field is analyzed, as well as their evolution to an organized observatory model. From the evidence found in the literature, it can be observed that databases and information centers constitute the initial structures of the observatories, which arise as they fulfill functions that are not served by other structures or organizations. Considering historical conditions, such as the information crisis and technological advances in the post-World War II period, the emergence of new phenomena in the area of Information Science is identified, that involves the creation of information centers and their variations, encouraged by the need to obtain ...

The research was developed by means of the following steps: (i) corpus delimitation and annotation; (ii) features selection; (iii) extraction of the training corpus, and (iv) class balancing, training and testing. Our study shows that features related to argumentation mining can improve the automatic essay scoring performance compared to the set of usual features. The main contribution of this paper is to demonstrate that argument marking procedures to improve score prediction in essays classification can produce better results. Moreover, it remained clear that essays classification does not depends on the number of features but rather on the ability of creating meaningful features for a given

A primeira vertente de pesquisa explorou, principalmente, dados estruturados. Mais recentemente, passou-se a dar mais atencao a dados na forma de texto. Entretanto, passados alguns anos de pesquisa em mineracao de texto, observa-se que esse tipo de tecnologia ainda e pouco explorado. Considerando que a maior parte das informacoes disponiveis esta em forma textual e que nessa forma podem estar escondidos padroes importantes questiona-se o porque da pouca utilizacao de mineracao de texto. Para tentar responder essa questao, foram enumeradas como possiveis causas para a carencia de aplicacoes de text mining: (a) pouca usabilidade das ferramentas; (b) existencia de poucos relatos de experiencias de sucesso; e (c) falta de uma metodologia adequada.

The studied approaches do not propose a repository for cataloguing applications or tools for discovering IoT applications for reuse. The purpose of this research is twofold: (i) propose a repository model to catalogue IoT applications, and (ii) present a tool for discovering IoT applications for reuse. The goal is to enable the search and reuse of existing solutions to avoid rework and to facilitate the development of applications for IoT. Based on the proposed approach, a proof of concept was implemented by means of a prototype. For the discovery process, a version of a k-NN (k-Nearest Neighbor) algorithm was adapted to use both Euclidean and Levenshtein distances. This was necessary due to descriptor types required to identify the applications. The prototype was applied to a case study with promising results, pointing out the usefulness of this proposal.

Utilizaram-se as contribuições da Arquitetura da Informação, enquanto disciplina científica para a construção de ontologias organizacionais. É proposto um processo de elaboração de ontologias, cuja principal vantagem é prover um conjunto de diretrizes para a construção de ontologias, com propriedades de um construto científico, incluindo completude ao artefato, no que tange às características desejáveis. Serviu-se do Método de Arquitetura da Informação Aplicada (MAIA) para a condução do processo de construção de ontologias. Um estudo de caso foi desenvolvido no domínio financeiro. O principal resultado foi o mapeamento das contribuições do CPAI em recomendações de uso para a construção de ontologias de domínio.Palavras-chave: Ontologia. Arquitetura da Informação.

Research paper thumbnail of A Resource-Oriented Model for Services Management and Discovering in SOA

The structural model is composed by a set of metaclasses which allow representation and descriptions of services, as well as different types of service components and granularities for composition and reuse. The model includes procedures to find and retrieve candidates to build composite services for meeting specific needs and purposes. Candidate services are found and retrieved by means of intelligent discovery mechanisms on the basis of a set of descriptors. The discovery procedure adopts a Case-Based Reasoning approach, in which the services are considered as cases that are kept and indexed in a repository.

Research paper thumbnail of An Approach for Text Mining Based on Noun Phrases

Smart Innovation, Systems and Technologies, 2015

The use of noun phrases as descriptors for text mining vectors has been proposed to overcome the ... more The use of noun phrases as descriptors for text mining vectors has been proposed to overcome the poor semantic of the traditional bag-of-words (BOW). However, the solutions found in the literature are unsatisfactory, mainly due to the use of static definitions for noun phrases and the fact that noun phrases per se do not enable an adequate relevance representation since they are expressions that barely repeat. We present an approach to deal with these problems by (i) introducing a process that enables the definition of noun phrases interactively and (ii) considering similar noun phrases as a unique term. A case study compares both approaches, the one proposed in this paper and the other based on BOW. The main contribution of this paper is the improvement of the preprocessing phase of text mining, leading to better results in the overall process.
