Ontology learning from text: a soft computing paradigm

Text-based information accounts for more than 80% of today’s Web content. They consist of Web pages written in different natural languages. As the semantic Web aims at turning the current Web into a machine-understandable knowledge repository, availability of multilingual ontology thus becomes an issue at the core of a multilingual semantic Web. However, multilingual ontology is too complex and resource intensive to be constructed manually. In this paper, we propose a three-layer model built on top of a soft computing framework to automatically acquire a multilingual ontology from domain specific parallel texts. The objective is to enable semantic smart information access regardless of language over the Semantic Web.

Language and learning preferences : a study of university students in Australia

This study sought to investigate the preferences for language use and modes of learning of university students who were completing undergraduate degrees in Australia. Of the sixty students surveyed, forty percent were international students. For seventy five percent of all students sampled, either they or their parents (or both) were bi- or multilingual. Questions which this research sought to answer were: Do the preferences for learning of university students differ according to the culture and / or language backgrounds of the students? Does an individual student’s preferred learning style influence the student’s preferences for learning in a group situation? For students whose first language is not English, do their preferences for language use vary in group learning? General findings resulting from a statistical analysis of responses to the questionnaire indicated in many, but not all, cases that the preferences for learning of university students differed according to the cultural and / or language backgrounds of the students, that an individual student’s preferred learning style influenced the student’s preferences for learning in a group situation, and that the preferences for language use of students whose first language was not English varied in group learning. Reid’s (1984 in Richards, J.C. & Lockhart, C., 1994) “Perceptual learning style preference questionnaire” comprised one section of the questionnaire for this study. This replication made possible a comparison of the findings which related to students’ learning styles from this study with findings from similar studies in which Reid’s survey instrument had been used. Findings of the present study indicate a number of differences from Reid’s findings. This study found, for example, that most language groups showed a minor preference for group learning using this survey instrument whereas Reid had found that group learning was a negligible preference for most of the language groups in her study. This study may give tertiary educators a greater understanding of their students’ preferences for group and other learning styles. It may also inform them of the likely preferences for language use of those of their students who have first languages other than English. Future students may benefit from this.

Teaching and learning mathematics and science in a second or third language

 This study investigates the interaction between languages used for particular purposes in mathematics and science classrooms and the accompanying multimodal resources that support teachers’ strategies. The dual investigation sets this study apart, and produces its originality and contribution to the field. It develops a novel multimodal description of pedagogic strategies in multilingual mathematics and science classrooms in Malaysia.
