Grammar Model and Grammar Induction in the System NL PAGE
نویسنده
چکیده
The input to the natural language parser generation system NL PAGE is in the form of an annotated natural language text, which is used to generate a grammar and a lexicon. This paper describes the format of the text, a new grammar model that is used in the system, and the process of grammar induction.

یک مدل بیزی برای استخراج باناظر گرامر زبان طبیعی
In this paper, we show that the problem of grammar induction could be modeled as a combination of several model selection problems. We use the infinite generalization of a Bayesian model of cognition to solve each model selection problem in our grammar induction model. This Bayesian model is capable of solving model selection problems, consistent with human cognition. We also show that using th...
متن کاملLearning Classifier System Approach to Natural Language Grammar Induction
This paper describes an evolutionary approach to the problem of inferring non-stochastic context-free grammar (CFG) from natural language (NL) corpora. The approach employs Grammar-based Classifier System (GCS). GCS is a new version of Learning Classifier Systems in which classifiers are represented by CFG in Chomsky Normal Form. GCS has been tested on the NL corpora, and it provided comparable...
متن کاملElicitation, Recast, and Meta-Linguistic Feedback in Form-Focused Exchanges: Effects of Feedback Modality on Multimedia Grammar Instruction
This research explores the effects of three computer-mediated feedback modalities, that is, elicitation, recast, and meta-linguistics, on the learning of English participial, gerund, and infinitival phrases among Iranian intermediate-level EFL learners. The overriding focus of the present study was to investigate whether different types of feedback given through form-focused computer-human exch...

This paper explores male and female students' and teachers' perceptions of the role of grammar instruction and corrective feedback. A questionnaire, administered to 60 male and female intermediate EFL students (30 males and 30 females) and 40 teachers (20 males and 20 females), elicited student and teacher perceptions concerning the role of explicit grammar instruction and corrective feedback i...
متن کاملAutomatic induction of n-gram language models from a natural language grammar
This paper details our work in developing a technique which can automatically generate class n-gram language models from natural language (NL) grammars in dialogue systems. The procedure eliminates the need for double maintenance of the recognizer language model and NL grammar. The resulting language model adopts the standard class n-gram framework for computational efficiency. Moreover, both t...
