Efforts to represent knowledge effectively have been central to progress in various aspects of medical informatics. These efforts range from relatively simple "electronic textbooks" to fairly sophisticated knowledge-based systems, which function as well as, or even better than, h...

This article describes a methodology for the enterprise knowledge modeling and the maintenance of an Organizacional Memory (OM). Its based on integration of management practices with information systems and knowledge engineering technologies. Our goal is aid the modeling of the o...

Decision support systems in the medical field have to be easily modified by medical experts themselves. The authors have designed a knowledge acquisition tool to facilitate the creation and maintenance of a knowledge base by the domain expert and its sharing and reuse by other in...

The main role of Information Technology in Knowledge Management is to accelerate the speed of knowledge transfer. The Knowledge Management softwares intend to help the process of collecting and structuring the knowledge of groups of individuals in order to make this knowledge ava...

Objective: To assess the effects of a computer-based patient record system on human cognition. Computer-based patient record systems can be considered "cognitive artifacts," which shape the way in which health care workers obtain, organize, and reason with knowledge....

Abstract: The research provides a knowledge representation able to describe the influence of Network Society concepts on Productive Processes. To do so, it is adopted an ontological engineering based approach supplemented with classical methods for scientific research. The utilit...

ln the Power Transmission Systems operation, voltagej reactive power probIems can occur, any time due to contingencies andjor changes in demando However, appropriate contraI decisions are necessary in a short time, in order to improve the operating state and not to put the securi...

The information extraction about a particular domain is a big difficulty in software development. Intrinsic aspects, peculiar domain language and the plurality of domains require knowledge and experience from requirements engineer for success in information obtaining. Due to the ...

Objective: Clinical information systems typically present patient data in chronologic order, organized by the source of the information (e.g., laboratory, radiology). This study evaluates the functionality and utility of a knowledge-based system that generates concept-oriented vi...

As part of an enterprise effort to develop new clinical information systems at Intermountain Health Care, the authors have built a knowledge authoring tool that facilitates the development and refinement of medical knowledge content. At present, users of the application can compo...

This work presents a developing approach of simulation models, including the necessary computing tools and techniques, and, also, a supporting methodology for project design and implementation. A beef cattle simulation model was developed by using the SimuCAD methodology (graphic...

Artificial Neural Networks (ANN) have successfully been used in tasks as the mapping of complex functions and pattern recognition. This success is due to the ANN ability to make calculations of complicated and undetermined data, learn from examples, generalize the learned informa...

Nowadays, knowledge modelling and processing are topics of interest for Artificial Intelligence researchers. The proposal of this work is to develop a modification of classical Petri Nets, which one is based on principles of Fuzzy Logic and Petri Nets, called Extended Fuzzy Petri...

There is a present claim for the development of systems able to promote adequate means of acquisition, handling and dissemination of knowledge. The dissertation highlights this need and proposes an ontology named ONTO ISGE, which represents the knowledge domain concerning the Str...

Knowledge representation involves enumeration of conceptual symbols and arrangement of these symbols into some meaningful structure. Medical knowledge representation has traditionally focused more on the structure than the symbols. Several significant efforts are under way, at l...

The case study in our research aims to analyze whether local productive systems are really involved in knowledge management practices or not. Our research was conducted at the Pólo Brasileiro de Coméstico Brazilian Cosmetics Cluster, a non-profit organization, which operates in c...

The objective of this article is to assess the implications of systems architecture on the establishment of organizational learning cycles, and its influence on possible forms of process integration. Dynamics of innovation of complex systems do not follow the pattern of mass-prod...

Linking the electronic health record to the digital library is a Web-era reformulation of the long-standing informatics goal of seamless integration of automated clinical data and relevant knowledge-based information to support informed decisions. The spread of the Internet, ...

Future air traffic management (ATM) systems have been identified as a matter of great significance for the evolution of future air navigation systems (FANS). As one function of ATM, Air Traffic Flow Management (ATFM) provides a service complementary to Air Traffic Control (ATC). ...

Objective: A gap exists between the information contained in published clinical practice guidelines and the knowledge and information that are necessary to implement them. This work describes a process to systematize and make explicit the translation of document-based knowledge i...
