This paper proposes a method for fraud detection in automated selection exams, using knowledge engineering tools for identifying groups of answers with a strong indication of fraud, based on probabilistic evidence. Founded on an analysis of the wrong answers of the various candidates, the proposed method enables identification of suspicions, and evidence of fraud attempts through finding candid...

In recent years, knowledge-based systems have become one of the most popular approaches for solving engineering problems. Along with the rising complexity of the problem, knowledge management, acquisition, representation, inferencing, and refinement become increasingly difficult. Conventionally, tasks of knowledge acquisition and representation are accomplished separately and sequentially. Know...

We investigate the semantics of the logical systems obtained by introducing the modalities and ♦ into the family of substructural implication logics (including relevant, linear and intuitionistic implication). Then, in the spirit of the LDS (Labelled Deductive Systems) methodology, we “import” this semantics into the classical proof system KE. This leads to the formulation of a uniform labelled...

A first research project, aimed at gathering information about the State-of-the-Practice in building knowledgebased systems with practical applications, needed a preliminary study to ascertain if KBSs still exist today as a research topic, or the interest in them actually faded. The study was also required for finding organisations currently building KBSs for different domains. The project’s ai...

This article introduces the current agent-oriented methodologies. It discusseswhat approacheshave been followed (mainly extending existing objectoriented and knowledge engineering methodologies), the suitability of these approaches for agent modelling, and some conclusions drawn from the survey.

. We present in this paper, a modelling of an expertise in pragmatics. We follow knowledge engineering techniques and observe the expert when he analyses a social discussion forum. Then a number of models are defined. These models emphasises the process followed by the expert and a number of criteria used in his analysis. Results can be used as guides that help to understand and annotate discus...
