Despite the problems presented by lexical errors in second language (L2) communication, most computer assisted language learning (CALL) programs tend to focus on the acquisition of grammar points rather than on the development of the L2 lexicon. In addition, CALL vocabulary tasks are typically limited in scope and mechanical in nature, covering…

Possibilities and limitations of a natural language processing technology, with its central engine, the parser, are discussed. Observations are drawn from a project by the U.S. Army Research Institute to develop a German tutor, the BRIDGE, which revolves around a parser. (Contains 19 references.) (Author/LB)

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. The project uses various corpora, including a Chinese-English parallel corpus ("Sinorama") and various natural language processing (NLP) tools to construct effective English…
