APPLICATIONS OF ARTIFICIAL-INTELLIGENCE IN ORGANIC-CHEMISTRY .17. NEW PROGRAMS IN THE SISTEMAT PROJECT

This work describes the new improvements of the SISTEMAT project, one system for structural elucidation mainly in the field of Natural Products Chemistry. Some examples of the resolution of problems using C-13 Nuclear Magnetic Resonance and Mass Spectroscopy are given. Programs to discover new heuristic rules for structure generation are discussed. The data base contains about 10000 C-13 NMR spectra.

Combining artificial intelligence and human problem solving: Proposing a new architecture for ITS's

This paper shows a comparative study between the Artificial Intelligence Problem Solving and the Human Problem Solving. The study is based on the solution by many ways of problems proposed via multiple-choice questions. General techniques used by humans to solve this kind of problems are grouped in blocks and each block is divided in steps. A new architecture for ITS - Intelligent Tutoring System is proposed to support experts' knowledge representation and novices' activities. Problems are represented by a text and feasible answers with particular meaning and form, to be rigorously analyzed by the solver to find the right one. Paths through a conceptual space of states represent each right solution.

JSEG-based image segmentation in computer vision for agricultural mobile robot navigation

This project aims to apply image processing techniques in computer vision featuring an omnidirectional vision system to agricultural mobile robots (AMR) used for trajectory navigation problems, as well as localization matters. To carry through this task, computational methods based on the JSEG algorithm were used to provide the classification and the characterization of such problems, together with Artificial Neural Networks (ANN) for pattern recognition. Therefore, it was possible to run simulations and carry out analyses of the performance of JSEG image segmentation technique through Matlab/Octave platforms, along with the application of customized Back-propagation algorithm and statistical methods in a Simulink environment. Having the aforementioned procedures been done, it was practicable to classify and also characterize the HSV space color segments, not to mention allow the recognition of patterns in which reasonably accurate results were obtained.

Valorização de beleza e inteligência por adolescentes de diferentes classes sociais

Participaram do estudo 180 adolescentes (90M e 90F) com idades variando entre 15 e 17 anos, alunos do ensino médio, pertencentes a diferentes classes sociais. Foram comparados gêneros e classes sócio-econômicas a respeito dos valores de beleza e de inteligência que adolescentes atribuem a si próprios e, numa situação hipotética e de forma mutuamente exclusiva, qual desses atributos foram mais valorizados para si mesmos e para possíveis parceiros. Os resultados mostraram que os rapazes de classe alta atribuíram-se maiores notas de inteligência. Adolescentes de ambos sexos pertencentes à classe baixa gostariam de possuir um maior nível de inteligência em detrimento da beleza, enquanto que adolescentes de classe alta preferem o equilíbrio entre beleza e inteligência. As moças valorizam mais a inteligência em seus parceiros que os rapazes, os quais valorizam mais a beleza em suas parceiras.

Inteligência coletiva: um olhar sobre a produção de Pierre Lévy

Collective intelligence is an interdisciplinary subject and it has been explored for many different knowledge areas. As a proposal totally tied to the concept of information and information technologies and communication, it is considered as relevant the discussion about the topic within the scope of Information Science. Therefore, a descriptive and exploratory study was carried out from Pierre Levy's work, identifying the precepts of collective intelligence and its ambiences and implications. The research is documental, focusing on determining the state of the art of the production about collective intelligence, verifying what was produced by Pierre Lévy and by other authors about the subject, in order to point out what possible interventions of Information Science on studies about collective intelligence. The research showed that that in the field of Information Science there is little research on the theoretical level about collective intelligence. Nevertheless, discussions about the representation and organization of collective intelligence in digital environments have been recurrent in the present, thus opening new fields of approach between Information Science and conceptual research and practice in collective intelligence.
