POIROT is an integration framework for combining machine learning mechanisms to learn hierarchical models of web services procedures from a single or very small set of demonstration examples. The system is organized around a shared representation language for communications with a central hypothesis blackboard. Component learning systems share semantic representations of their hypotheses (gener...

Author article stakes part in several projects focused just on development of technical creativity and imagination in students of faculties of education, teachers and primary school pupils. The article deals with the teacher’s approach to the teaching of psychomotor skills, while specifically seeking to answer whether among teachers of technical education and practical activities, there are gro...

Ontologies constitute an approach for knowledge representation that can be shared establishing a shared vocabulary for different applications and are also the backbone of the Semantic Web. Thus a fast and efficient ontology development is a requirement for the success of many knowledge based systems and for the Semantic Web itself. However, ontology development is a difficult and time consuming...

Experiments 1 and 2 delivered conditioned stimuli (CSs) at random times and unconditioned stimuli (USs) at either fixed (Experiment 1) or random (Experiment 2) intervals. In Experiment 3, CS duration was manipulated, and US deliveries occurred at random during the background. In all 3 experiments, the mean rate of responding (head entries into the food cup) in the background was determined by t...

Despite its ubiquity in human learning, very little work has been done in artificiaJ intelligence on agents that learn from interactive natural language instructions. In this paper, we examine the problem of learning procedures from interactive, situated instruction, in which the student is attempting to perform tasks within the instructional domain, and asks for instruction when it is needed. ...

This paper describes a program that learns procedures b\ examining worked-out examples in a textbook and bv working problems I wo kinds of production (If-then) rules are created: working forward rules that produce an action when a proceduie is executed and difference rules that suggest operators from observed transformations. Dining example learning, the program examines two states in an exampl...

Recent studies have shown that multiple brain areas contribute to different stages and aspects of procedural learning. On the basis of a series of studies using a sequence-learning task with trial-and-error, we propose a hypothetical scheme in which a sequential procedure is acquired independently by two cortical systems, one using spatial coordinates and the other using motor coordinates. They...

In this electronic age, we are all knowledge workers, tackling on daily basis the information that flows through our email, file systems, web browsers, calendars, and various other desktop applications. Email has come to be the center of desktop activity for many of us: we set up meetings, exchange documents, manage projects, forward interesting links, track requisitions, and perform a whole ho...

We develop two related themes, learning procedures and knowledge transfer. This paper introduces two methods for learning procedures and one for transferring previously-learned knowledge to a slightly different task. We demonstrate by experiment that transfer accelerates learning.

reading development and instruction is a pedagogical priority at all academic levels. historically, in the educational field, numerous efforts have been made to facilitate the complex process of foreign language reading comprehension. more recently, increasing attention has been paid to the use of computers for developing reading comprehension skills and various efforts have been made in this r...
