Most of the information needed for the management in the decision making process is essentially based on sub-jective and imprecise concepts expressed primarily by "experts" in a natural language or based in simples indica-tors and it’s not capable to check the strategy in a more integral way. In the...

Trying to combine the easy-to-use tag-based annotations and the accurateness of structured formal annotations, a semantic enhancement of learning object repositories is proposed in this paper. Its potential impact to accessibility in the user experience is evaluated whilst similarities and differences...

In this paper, an extended method for ontology learning from concept maps is presented. Concept maps are a flex-ible and informal knowledge representation, while ontol-ogies are semantically formalized representations oriented to be processing by intelligent systems. The mapping be-tween them is a formal...

In the last decade, the interest for temporal data analysis methods has increased significantly in many application areas. One of these areas is the medical field, in which temporal data is in the core of innumerous diagnosis exams. However, only a small portion of all gathered medical data is properly...

Telemedicine can facilitate the examination and diagnosis of patients in locations with lack of resources and medical experts. This paper presents an innovative method and a computer system that allows real-time text, voice and video interaction among participants and data sharing of colonoscopy exams...

In this paper a new taxonomy for feature selection algorithms created for high-dimensional datasets is proposed. Also, several selectors are described, analyzed and evaluated. It was observed that the Cfs-SFS algorithm reached the best solutions in most of the cases. Nevertheless, its application in...

The present research analyzes the management of the knowledge with regard to its transfer in an educational institution located in Medellin, Colombia. A mixed re-search approach was used by conducting survey to 25 teachers, in order to measure the knowledge transfer made after taking a training course...

Underpinned by the vertiginous progress of Informatics and Communication Technologies, new evolutions of de-cision technologies are coming with the consequent bene-fit for decision makers and users in general. The integra-tion of Geographical Information Systems (GIS) and De-cision Support Systems (DSS)...

The integration between the Business and Information Technologies (IT) has become one of the main priorities in today’s organizations. To face this issue, the results of this investigation have been centered in efforts to link a model to identify the level of maturity of the strategic integration of...

Traditionally, data views are seen as static, syntactically correct, data sets. The semantics of the data is not explicitly encoded in RDB (relational databases) but implicitly on the application level. However, the needs to create context-aware browsing methods in changing scenarios are demanding more...

Nowadays, most Spatial Decision Support Systems (SDSSs) are designed to solve a specific problem in a given region. This fact makes rather difficult or even im-possible to develop comparative analyses and studies among different solutions. This research presents a ge-neric rule-based spatial decision...

The need to satisfy a more demanding customer in a scenery where deadlines and costs must be ever smaller to maintain competitiveness, together with increased uncertainty about demand, has been leading organizations to collaborate to such a level that now the competition is not between isolated enterprises,...

Information processed by applications is usually stored in databases or filing systems, allowing each system to use its own interface. As the files are not stored transparently, it is necessary to define data models to efficiently manage the information. This study proposes a process for storing information...
