Sensitive parsing: error analysis and explanation in an intelligent language tutoring system
نویسنده
چکیده
We present a uniform framework for dealing with errors in natural language sentences within the context of :automated second language teaching. The idea is to use a feature grammar and to analyse errors as being sentences where features have other values than those they should have. By using a feature grammar it is possible to describe various types of errors (agreement, syntactic and semantic errors) in a uniform framework, to define in a clear and transparent way what an error is and this is very important for our application to analyse errors as arising form a misunderstanding or ignorance of grammatical rules on the part of students.

An improved joint model: POS tagging and dependency parsing
Dependency parsing is a way of syntactic parsing and a natural language that automatically analyzes the dependency structure of sentences, and the input for each sentence creates a dependency graph. Part-Of-Speech (POS) tagging is a prerequisite for dependency parsing. Generally, dependency parsers do the POS tagging task along with dependency parsing in a pipeline mode. Unfortunately, in pipel...
متن کاملAn Effective Application of Natural Language Processing in Second Language Instruction
This paper presents an intelligent CALI system called “Nihongo-CALI” (Japanese Computer Assisted Language Instruction), which employs natural language processing to provide immediate, grammatically sophisticated feedback to students in an interactive environment. Using this system, Nagata (1993) previously compared the effectiveness of the two different levels of computer feedback for teaching ...
متن کاملUnderstanding Complex Natural Language Explanations In Tutorial Applications
We describe the WHY2-ATLAS intelligent tutoring system for qualitative physics that interacts with students via natural language dialogue. We focus on the issue of analyzing and responding to multisentential explanations. We explore an approach that combines a statistical classifier, multiple semantic parsers and a formal reasoner for achieving a deeper understanding of these explanations in or...
متن کاملIntegrating Affect Sensors in an Intelligent Tutoring System
This project augments an existing intelligent tutoring system (AutoTutor) that helps learners construct explanations by interacting with them in natural language and helping them use simulation environments. The research aims to develop an agile learning environment that is sensitive to a learner’s affective state, presuming that this will promote learning. We integrate state-of-the-art, nonint...
متن کاملAnalysis of Learning Curves for Weighted Constraint-based Tutoring Systems
Weighted constraints have been proven a useful means to enhance the quality of error diagnosis, e.g., in the domain of natural language parsing. In this paper, we propose an heuristic approach using constraint weights to analyze learning curves for weighted constraint-based tutoring systems as an addition (or alternative) to the commonly used analysis of pre-/post-test comparisons. Using a tuto...
