Disponibilização de cursos à distância : uma reflexão

O ensino/aprendizagem à distância pode ser uma forma de ultrapassar alguns dos problemas causados pelo crescente número de candidatos a maiores níveis de qualificação, num contexto em que os recursos não evoluem na mesma proporção. Existem variadas abordagens ao problema da disponibilização de sistemas de suporte ao ensino/aprendizagem à distância, bem como dos cursos que nesse contexto podem ser oferecidos. A...

Leveraging knowledge from different communities using ontologies

The purpose of this paper is to provide research based understanding of leveraging knowledge and managing knowledge within and across several communities using the poverty domain as a case study. We hypothesize that leveraging knowledge with a good taxonomy and a good integration process are good approaches to organize and share knowledge. Problems appear when a group of people in different communities share da...

Semantic interrelation in distributed system through green computing ontology

Green computing refers to the system that provides minimal impact on the environment. When we are talking about green computing we discuss about how much energy is used by the system, such as energy used by the system, time used for the search process, and how effective the system is. Related to that issue, trough this paper we want to proposes a new effort to achieve Green Computing in heterogeneous data in di...

Solving problem of ambiguity terms using ontology

Humans as God's creatures were endowed with brain used to think and to process the received knowledge. Human brain links knowledge into a giant network of ideas, memories, predictions and beliefs. Everything is interconnected in the brain. Human can understand the meaning of the same variable even if that variable has an ambiguous meaning. In another scenario, humans can understand the same thing based on diffe...

Integrating large knowledge repositories in multiagent ontologies

Knowledge is people’s personal map of the world. According to the knowledge differences, it is possible different groups of people have different perceptions about the same reality. Each perception can be represented by using ontologies. In the research underlying this paper we are dealing with a multiple ontologies. In that context, each agent explores its own ontology. The goal of this research is to generate...

Solving problems of data heterogeneity, semantic heterogeneity and data inequal...

Knowledge is people’s personal map and people’s personal model of the world. Knowledge acquisition involves complex cognitive processes such as perception, communication, and reasoning. According to the knowledge differences, then it is possible for people have a different perception to attain awareness or understand the environment or reality. This paper provides a case study where there is a group of people i...

Periódicos científicos digitais e ontologia : uma pesquisa

Apresenta pesquisa sobre periódicos científicos digitais e a construção de ontologia de referência, identificando a importância dos mesmos como veículos propulsores das ciências, seu formato digital e sua interoperabilidade. Trata-se de uma pesquisa documental e experimental, objetivando desenvolver uma ontologia que padronize os elementos (metadados) essenciais que estruturam, criam e mantém um periódico cient...

Enhancing web supported learning by adding a management layer to SCORM complian...

Many Web based learning experiences fail due to bad or absent support. LMSs (learning management systems) must incorporate mechanisms for real time monitoring of the involvement of each participant in a course, allowing the detection of deviations to the scheduled activities, enabling the correction of these deviations (Ramos et al., 2001). The principal standardization projects in the area do not cover this ty...

Enhancing web supported learning in higher education by adding a management lay...

There are many situations in the e-Learning experiences that can compromise the success of the courses. Many times simple reasons are great enough to motivate people to abandon them. For example, if someone does not execute a programmed activity inside the defined window of time, it can compromise the rest of the course to that person. In such situations it would be important that the teacher knew about the sit...
