We propose a new educational framework supporting learners in adoption of vocabulary and knowledge for various personalized and engaging pedagogic purposes. The most essential concepts of learning topic are linked based on the shortest connecting paths in hyperlink network of Wikipedia encyclopedia assisted with Wiktionary dictionary. In resulting pedagogic conceptual network learner traverses ...

We propose a new computational method for generating learning paths in educational texts. The method relies on forming vocabulary co-occurrence networks among articles of Wikipedia online encyclopedia and exploiting random explorations to generate route weighting parameters to form pedagogic co-occurrence networks. Motivated by previous research about scale-free small-world networks we suggest ...

Shrinkage estimation of the covariance matrix of asset returns was introduced to the finance profession several years ago. Since then, the approach has also received considerable attention in various life science studies, as a remedial measure for covariance matrix estimation with insufficient observations of the underlying variables. The approach is about taking a weighted average of the sampl...

This paper gives an overview of a framework for utilizing conversational agents to promote acquisition of intercultural communication skills. Adaptation plays an important and increasing role, in creating courses that ar...

One of the typical problems of Natural Language Processing (NLP) is the explosive property of the parser and this is aggravated in an Intelligent Language Tutoring System (ILTS) because the grammar is unconstrained and admits even more analyses. NLP applications frequently incorporate techniques for selecting a preferred parse. Computational criteria, however, are insufficient for a pedagogic s...

Over the last decade, there has been a rapid increase in doctoral enrolments of Asian international students in Australian universities. While policies have been developed to meet the needs of these students, there seems to be some confusion around the terms internationalisation, globalisation, bi-cultural, inter-cultural, multi-cultural, and trans-cultural within these policies. In this paper,...
