TAILIEUCHUNG - Báo cáo khoa học: "TENSE GENERATION IN AN INTELLIGENT TUTOR FOR FOREIGN LANGUAGE TEACHING: SOME ISSUES IN THE DESIGN OF THE VERB EXPERT"

The paper presents some of the results obtained within a research project aimed at developing ET (English Tutor), an intelligent tutoring system which supports Italian students in learning the English verbs. We concentrate on one of the most important modules of the system, the domain (. verb) expert which is devoted to generate, in a cognitively transparent way, the right tense for the verb(s) appearing in the exercises presented to the student. An example which highlights the main capabilities of the verb expert is provided. A prototype version of ET has been fully implemented. . | TENSE GENERATION IN AN INTELLIGENT TUTOR FOR FOREIGN LANGUAGE TEACHING SOME ISSUES IN THE DESIGN OF THE VERB EXPERT Danilo FUM Paolo Giangrandi Carlo Tasso Dipartimento dellEducazione Universita di Trieste Italy Laboratorio di Intelligenza Ardficiale Universita di Udine Italy via Zanon 6 - 33100 UDINE Italy tasso ABSTRACT The paper presents some of the results obtained within a research project aimed at developing ET English Tutor an intelligent tutoring system which supports Italian students in learning the English verbs.

INTRODUCTION In the course of its evolution English has lost most of the complexities which still characterize other Indo-European languages. Modern English for example has no declensions It makes minimum use of the subjunctive mood and adopts natural gender instead of the grammatical one. The language on the other hand has become more precise in other ways cases have thus been replaced by prepositions and fixed word order while subtle meaning distinctions can be conveyed through a highly sophisticated use of tense expressions. Learning correct verb usage is however exttemely difficult for non native speakers and causes ttoubles to people who study English as a foreign language. In order to overcome the difficulties which can be found in this and several other grammatical areas various attempts have been made to utilize Artificial Intelligence techniques for developing very sophisticated systems called Intelligent Tutoring Systems in the specif domain of foreign language teachin Barchan Woodmansee and Yazdani 1985 Cunningham Iberall and
