We present a new methodology to automate decision making over time and uncertainty. We adopt a knowledge-based model construction approach to support automated and interactive formulation of dynamic decision models, i.e., models that explicitly consider the effects of time. Our work integrates and extends different features of the existing frameworks. We incorporate a hybrid knowledge represent...
We describe our contribution to the Generating from Knowledge Bases (KBgen) challenge. Our system is learned in a bottom-up fashion, by inducing a probabilistic grammar that represents alignments between strings and parts of a knowledge graph. From these alignments, we extract information about the linearization and lexical choices associated with the target knowledge base, and build a simple g...
The usage of computer applications in the construction industry has steadily increased over the years, as has the complexity of many software applications. It is difficult for project personnel to become familiar with these ever-increasingly complex tools. Furthermore, the causes of many practical problems, such as project delays or escalating costs, are often not obvious from the outputs of th...
In last decades Knowledge Based System (KBS) became a common tool in a large number of Power Systems Control Centres (CC). In fact, the quantity, diversity and complexity of KBS increased significantly leading to important changes in KBS structure, especially in its nuclear components: knowledge representation and reasoning. The design of KBS applied in extremely dynamic environments demands th...
In this paper, we propose an operator model to detect and identify causes of failure in an emergency, based on which an alarm system in a process can be evaluated and improved. The operator model is a human processor model that includes a perceptual processor, short-term and long-term memories, a cognitive processor, and a motor processor. Knowledge bases for variable information, failure-sympt...
For the design of new applications in the information and communication technology (ICT) area with ever shorter lifecycles, the availability of the most recent knowledge is mandatory. The intervals within the acquired knowledge bases therefore have to be updated, become shorter and shorter. In this paper we present a new interactive webbased training system supported by the European Union to st...
abstract the present study was conducted in order to investigate the impact of an integrated model of form-focused and task-based instruction on iranian efl learners vocabulary learning and retention.it also aimed to detect efl learners attitude towards the implementation of form-focused task-based vocabulary instruction in the classroom. in order to address the purposes of this study, a sampl...
anxiety is one common disorder during childhood. in curing anxiety disorders, there are different types of psychological remedies, pharmotherapy, family therapy, and music therapy that can improve the individual’s anxiety, but we need some other remedies to improve social and emotional relationship and interactions. considering the importance of curing the anxiety disorders, the effect of sand ...
Diierent requirements for the representation of the factual knowledge for the use in mechanised reasoning systems are represented. In particular, we distinguish diier-ent types of knowledge: axioms, deenitions (for introducing concepts like \set" or \group") and theorems (for relating the concepts) for formulating concepts and their relationships, as well as proofs, examples and counterexamples...
