This paper describes research on the use of knowledge models (ontologies) for building computer-aided educational software in the field of control engineering. Ontologies are able to represent in the computer a very rich conceptual model of a given domain. This model can be used later for a number of purposes in different software applications. In…

This study attends to the possibilities of analyzing students' writings at a lexicogrammatical level in terms of their use of linguistic resources, and the insights afforded by this approach into the challenges students faced when they employed the language of school science related to the phenomenon of expansion. For the purpose of this study,…

Reports on a project showing that relational data models, including unnormalized models that allow the nesting of relations, cannot fully capture the structural properties of lexical information. A feature-based model that allows for a full representation of some nesting and defines a factoring mechanism is described and demonstrated. (38…

Discusses lexicographic theory, various problems and models behind dictionary construction, and the role of the "cultural dictionary." (AM)

Demonstrates the use of a directed graph model as a tool for finding desirable minimum vocabularies to be used in indexing and information retrieval. The basic algorithm is outlined, possible enhancements to the model are discussed, and further research questions are suggested. (Author/CLB)

MARANAO, OF THE MALAYO-POLYNESIAN LANGUAGE GROUP, IS ONE OF THE EIGHT MAJOR LANGUAGES IN THE PHILIPPINES AND IS SPOKEN BY 400,000 MOSLEMS ON THE ISLAND OF MINDANAO. THIS DICTIONARY, BASED PRIMARILY ON THE SPOKEN FORM OF THE LANGUAGE, CONTAINS 18,000 MARANAO ENTRIES IN PART I AND THEIR ALPHABETIZED ENGLISH GLOSSES CROSS-REFERENCED IN PART II. THE…

In a review of two decades of vocabulary research, it is noted that vocabulary has moved from "poor relation" to "guest of honor" status in language teaching. Research areas include specialized bibliographies, vocabulary acquisition, vocabulary teaching, course materials, and lexicography. Future research directions are suggested, including…

TWO VIEWS OF A DICTIONARY'S PURPOSE CAME INTO SHARP CONFLICT UPON THE PUBLICATION OF WEBSTER'S "THIRD NEW INTERNATIONAL UNABRIDGED DICTIONARY." THE FIRST VIEW IS THAT A DICTIONARY IS A REFERENCE BOOK ON LANGUAGE ETIQUETTE, AN AUTHORITY FOR MAINTAINING THE PURITY OF THE ENGLISH LANGUAGE. THE SECOND IS THAT A DICTIONARY IS A SCIENTIFIC…

A sequential screening procedure has been proposed in Queensland, based on what is known in decision theory as a 'lexicographic ordering.' The concept is explained, and some of the associated assumptions, implications and shortcomings are examined. (Author/MLW)

Reports on a study that analyzed and compared a restricted set of full-text articles from a sub-specialty of biochemistry in terms of co-occurrences and co-absences of words. The consequences for the lexicographical approach to generating artificial intelligence from scientific texts are discussed. (JAK)

This document includes the abstracts of papers presented at a seminar intended to provide a survey of how the models and techniques of linguistics may be applied to the description of the German language, with a view to improving the understanding of some of the practical problems of first and second language learning. Topics range over a wide…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
