Although BNs have been used successfully for many medical diagnosis problems, there have been few applications to epidemiological data where data mining methods play a significant role. In this paper, we look at the application of BNs to epidemiological data,…

Data mining researchers have long been concerned with the application of tools to facilitate and improve data analysis on large, complex data sets. The current challenge is to make data mining and knowledge discovery systems applicable to a wider range…

Aspects of physico-chemical factors and zooplankton of Nguru Lake were studied for a period of twenty four months between May 2006 and April 2008.With the aim of acquiring the necessary knowledge for management of lakes in semi arid areas of…

The Knowledge Engineering Suite is an ontology production method, based on relationship networks, for knowledge representation inside specific contexts. The production of these ontologies has three basic steps, since catching the client data, knowledge base creation, and information retrieval and…

This paper investigates the distribution of epistemic modals in attitude contexts in three Romance languages, as well as their potential interaction with mood selection. We show that epistemics can appear in complements of attitudes of acceptance (Stalnaker 1984), but not…

There are only a few records for the jaguar (Panthera onca) in Oaxaca, hence it is considered to be a state with scarce knowledge on the species. This study presents an update regarding the geographic distribution of the species and…

This paper is a theoretical analysis, opening with the introduction where the problem of the research, the object of the research, the purpose of the research and the research methods are described. The analysis has revealed that the market situation,…

It is interesting and important to compare, analyze and assess the alternative tools that could be used in the area of Knowledge Representation. In this paper we present a reasearch line associated to this goal: to formally establish the relation…

In systems where agents are required to interact with a partially known and dynamic world, sensors can be used to obtain further knowledge about the environment. However, sensors may be unreliable, that is, they may deliver wrong information (due, e.g.,…

In this paper, a restricted domain question answering (QA) system is described. The design architecture of this QA system and the features that allow the adaptation of the QA system to the medical domain are also presented. The advantages of…
