In this paper we present a system for automatic correction of errors made by learners of English. The system has two novel aspects. First, machine-learned classifiers trained on large amounts of native data and a very large language model are combined to optimize the precision of suggested corrections. Second, the user can access real-life web…

Discusses the theoretical basis, implementation, and pedagogical considerations of CALLE (Computer-Aided Language Learning Environment), a dialogue-based beginning Spanish language instruction system. CALLE uses Lexical Functional Grammar Theory to analyze errors in student input. Sample screen is shown. (Author/LMO)

This paper describes the development of an innovative web-based environment for English language learning with advanced data-driven and statistical approaches.

Describes the language learning program "Acquire," which is a sample of grammar induction. It is a learning algorithm based on a pattern-matching scheme, using both a positive and negative network to reduce overgeneration. Language learning programs may be useful as tutorials for learning the syntax of a foreign language. (Author/LMO)

This paper describes a method in oral fluency evaluation for Tourism English according to a corpus-based lexical approach. Our main research focus is placed on measuring oral skill competence among Tourism English (TE) learners by contrasting their word use and linguistic fluency, achieved in two types of oral tasks, with corpus data frequencies.…
