This paper presents a new version of Robo-Sensei's NLP (Natural Language Processing) system which updates the version currently available as the software package "ROBO-SENSEI: Personal Japanese Tutor" (Nagata, 2004). Robo-Sensei's NLP system includes a lexicon, a morphological generator, a word segmentor, a morphological parser, a syntactic…

Four grammar checkers, all of French Canadian origin, were evaluated: "Le Correcteur 101,""GramR,""Hugo Plus," and "French Proofing Tools." Results indicate that "Le Correcteur 101" is the best French grammar checker on the market and worth its premium cost. (two references) (CK)

Describes an answer analysis system, called Answer Pattern Manager, that solves the difficult problem of recognizing student reproduction of spoken Japanese sentences. It allows all reasonable Roman spellings of Japanese words, while at the same time detecting mishearings and distinguishing between important and unimportant words. (Contains eight…

The strategy used in "Miniprof," a program designed to provide "intelligent" instruction on elementary topics in French, is described. At an erroneous response, the program engages the student in a Socratic dialog and uses three major functions: parsing, error diagnostics, and tutoring. (10 references) (Author/LB)

A typology for analyzing grammatical errors in student-written German compositions is presented and approaches to providing helpful error messages to student users of a parser-based writing aid are discussed. (19 references) (Author/LB)

Discusses how computer-assisted language learning programs can generate error messages to help students in different ways. The article points out that an easier solution is to program a computer to recognize several different kinds of generic errors not related to any particular question but applicable to many situations, in order to generate…

ALICE, a multimedia framework for intelligent computer-assisted language instruction (ICALI) at Carnegie Mellon University (PA), consists of a set of tools for building a number of different types of ICALI programs in any language. Its Natural Language Processing tools for syntactic error detection, morphological analysis, and generation of…

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)

SPANLAP (SPANish LAnguage Processing) is a computer program which attempts to engage students of Spanish in a free-form written dialog by allowing them to ask questions. The morphological and syntactic parsing process used in SPANLAP is explained. Sample dialog illustrates limitations of the current model. (Author/LMO)

Outlines the design considerations that go into making an authoring system. Uses examples from the author's system, "Private Tutor," to illustrate. Emphasis is on the concepts that define the operation of the authoring system. Also discusses design principles of "Private Tutor" in relation to the Macintosh computer. (Author/LMO)

A computer grammar checker is described that evolved from a sample of errors and resulting in a taxonomy of 14 main and 93 subtypes. Using a 1,402-word stem electronic dictionary, an augmented transition network parser, and a set of disambiguating rules, the checker provides feedback for 7 types of errors.

Describes the development in progress of a syntactic parser of German called "Syncheck," which uses the programing language "Prolog." The grammar is written in a formalism called "Definate Clause Grammar." The purpose of "Syncheck" is to provide advice on grammatical correctness to intermediate and advanced…

Presents essential principles to consider when designing free-form remedial/tutorial program courseware for second language learning. They include: (1) adaptability, in terms of instruction requirements and user population needs; (2) user-friendliness, to reduce machine-induced fears; (3) sophistication in error analysis; and (4) flexibility, to…

Describes development and evaluation of an error analysis procedure for a computer-assisted language learning program using natural language processing techniques. The program can be used for learning passive voice in Japanese on any World Wide Web browser. The program enables learners to type sentences freely, detects errors, and displays…
