1. On the role of economy in grammatical derivations Much recent work within generative grammar has made use ofthe idea that grammatical derivations exhibit a certain type of economy. The intuition behind this appücation of economy is a familiar one: that the well-formed sentences of a language are as simple as they can be (given the demands of expressiveness), and do not involve any unnecessar...

This paper presents the IJCNLP 2017 shared task for Chinese grammatical error diagnosis (CGED) which seeks to identify grammatical error types and their range of occurrence within sentences written by learners of Chinese as foreign language. We describe the task definition, data preparation, performance metrics, and evaluation results. Of the 13 teams registered for this shared task, 5 teams de...

This paper explores the contribution of a broad range of syntactic features to WSD: grammatical relations coded as the presence of adjuncts/arguments in isolation or as subcategorization frames, and instantiated grammatical relations between words. We have tested the performance of syntactic features using two different ML algorithms (Decision Lists and AdaBoost) on the Senseval-2 data. Adding ...

Children with language impairment (LI) show an overall immaturity in grammatical structure. This includes difficulties with basic sentence constituents, pronouns, verb form elaboration, negative and interrogative sentences, noun phrase elaboration, and complex sentences. This article describes explicit instruction and scaffolding strategies, based on a review of current research, that can be us...

Unlike Lexical Projections, Functional Projections (Extended Projections) are more of an ‘abstract’ in nature. Therefore, Functional Projections seem to be acquired later than Lexical Projections by the L2 learners. The present study investigates Iranian L2 learners’ acquisition of English Extended Projections taking into account their level of grammatical proficiency. Specifically, the aim is ...

Systemic functional grammar constructs a grammar for the purpose of text analysis to investigate how grammar is used as a means of making meaning. Grammatical metaphor is one of the language phenomena introduced by Halliday (2004) in the framework of functional grammar. The present work focuses on the application of Halliday’s metafunctional framework in health texts of English newspapers. The ...

Frequencies and discourse functions of grammatical subject types were investigated in a corpus of forty results and discussion sections selected from four disciplines (Applied Linguistics, Psychology, Chemistry, and Environmental Engineering). The results and discussion sections were selected from research articles that were published in 2008-2012 issues of prestigious high journals of ...

This paper presents the NLP-TEA 2016 shared task for Chinese grammatical error diagnosis which seeks to identify grammatical error types and their range of occurrence within sentences written by learners of Chinese as foreign language. We describe the task definition, data preparation, performance metrics, and evaluation results. Of the 15 teams registered for this shared task, 9 teams develope...

In this paper we will show that Grammatical Inference is applicable to Natural Language Processing. Given the wide and complex range of structures appearing in an unrestricted Natural Language like English, full Grammatical Inference, yielding a comprehensive syntactic and semantic definition of English, is too much to hope for at present. Instead, we focus on techniques for dealing with ambigu...
