Dependency Grammar has been used by Iinguists as the basis of the syntactic components of their grammar formalisms. It has also been used in natural langauge parsing. In China, attempts have been made to use this grammar formalism to parse Chinese sentences using corpus based techniques. This paper reviews the properties of Dependency Grammar as embodied in four axioms for the well-formedness conditions for dependency structures. It is shown that allowing mul tiple governors as done by some followers of this formalism is unnecessary. The practice of augmenting Dependency Grammar with functional labels is discussed in the light of building functional structures when the sentence is parsed. This will also facilitate semantic interpretion.retion.

This paper describes a method for automatic acquisition of wide-coverage treebank-based deep linguistic resources for Japanese, as part of a project on treebank-based induction of multilingual resources in the framework of Lexical-Functional Grammar (LFG). We automatically annotate LFG f-structure functional equations (i.e. labelled dependencies) to the Kyoto Text Corpus version 4.0 (KTC4) (Kurohashi and Nagao 1997) and the output of of Kurohashi-Nagao Parser (KNP) (Kurohashi and Nagao 1998), a dependency parser for Japanese. The original KTC4 and KNP provide unlabelled dependencies. Our method also includes zero pronoun identification. The performance of the f-structure annotation algorithm with zero-pronoun identification for KTC4 is evaluated against a manually-corrected Gold Standard of 500 sentences randomly chosen from KTC4 and results in a pred-only dependency f-score of 94.72%. The parsing experiments on KNP output yield a pred-only dependency f-score of 82.08%.

The interests in Machine Translation(MT) have gotten revitalized lately with the rapid expansion of internet users. MT technology has gone through several different stages of development, but the longest surviving methods usually maintains the following characteristics: the expand ability and flexibility based on proved linguistic formalism, the transfer method of translation, the continued efforts of systematic updates being made into the system. This paper introduces one such system, L&H Korean-English bidirectional MT system. This system uses Lexical-Functional Grammar as its linguistic framework. It also adopts the transfer method of MT and has been around on the market for over 10 years for other language pairs. Currently, the system covers over 10 different languages including Chinese, Japanese and Arabic, in addition to European languages. This paper will review the system in its core and discuss related tools and resources be ing used to enhance the quality of translation.

This study highlights some very important future directions for the revision of language forms in the 2007 Korean English Curriculum, expected to be made public in the summer of 2011. A critical review of the 2007 National English Curriculum shows that language forms exemplified in that curriculum are not well-chosen or well-sequenced from the viewpoint of grammar selection and gradation, and that no mention of structural labels or grammatical terminologies makes it hard for teachers to recognize their formal properties. To fulfill the original purpose that languages should be listed in the curriculum so that functional-notional syllabuses can be complemented by form-focused instruction, the study presents partial inventories of grammatical items with well-chosen and well-sequenced examples. Minimal descriptions are given to these inventories that are based on general notions or well-known grammatical notions. Occasional suggestions are also made for which language forms should be taught in which schools.

Practice of proof is considered in, the view of language and meta-mathematics, recognizing the role of proof that is the means of communication and development of mathematical understanding. Linguistic components in proof texts are symbol, verbal language and visual text, and contain the implicit knowledge in the meta-mathematics view. This study investigates the functions of linguistic elements according to Halliday's functional grammar and the rhetoric skills in proof texts in math textbook, teacher's note, and student's written text. We need to inquire into the aspects of language for mathematics learning process and the understanding and use of students' language.

본 연구의 목적은 빛에 대한 초등학생들의 이미지 스키마를 통해 이들의 개념적 은유 유형을 분석하는 것이다. 연구 참여자는 경상남도 G시의 한 개 초등학교 6학년 학생 162명이다. 이 연구를 위해 분석틀이 고안되었으며, 그 분석틀은 이미지 스키마 분석틀과 체계적 기능 문법 분석틀이다. 학생들의 빛 개념을 묻는 질문지도 개발되었다. 연구 결과는 다음과 같다. 첫째, 광원에 대해 학생들은 빛에 대해 두 가지의 구조를 가지고 있음을 보였으며, 그 두 가지는 빛이 광원으로부터 나와 직선으로 공간에 퍼져나간다는 것과 빛이 광원 주위에 정지해 있다는 것이다. 둘째, 물체를 보는 과정에 대한 이해에서는, 학생들은 과학자적 개념을 포함하여 5개의 구조를 나타냈다. 셋째, 빛의 반사에 대한 이해에서는 학생들은 과학자적 개념을 포함하여 4가지의 개념 구조를 나타냈다.

철학적 문제들의 발생은 언어의 논리에 대한 오해에 기인한다는 신념에 따라, 비트겐슈타인의 철학적 탐구는 언제나 언어의 논리 문제를 중심으로 전개되었다. 그의 철학적 작업은 실로 논리적 탐구였다고 할 수 있다. 그러나 그가 생각한 언어의 논리란 무엇인가? 그것은 처음부터 언어의 문법으로서 이해되었지만, 이 이해에는 그의 전후기에 중요한 변화가 있었다. 초기에 그는 언어의 논리를 이상적 표기법에서 실현되는 진리 함수적 구문론과 같은 것으로 이해했으나, 후기에 그는 언어의 논리를 언어놀이의 다양한 언어 사용 규칙들로서 보는 데로 나아갔다. 그것은 논리를 모든 가능성이 미리 규정되어 있는 매우 엄격하고 이상적인 하나의 보편적 문법 체계로서 보는 데서부터, 논리를 미리 생각되지 않은 가능성에 열려 있고 언어놀이들에 특유한 다양한 언어 사용 규칙들로 이루어진 문법 체계들로서 보게 되는 변화이다. 이 글은 그의 전후기 논리관의 상이한 핵심과 그 변화 이유를 다루고 있다. 특히 논리의 자율성과 필연성에 대한 그의 전후기의 관점 변화가 다루어진다.

The speech synthesis technology is widely used and its application area is also being broadened to an automatic response service, a learning system for handicapped person, etc. However, the sound quality of the speech synthesizer has not yet reached to the satisfactory level of users. To make a synthesized speech, the existing synthesizer generates rhythms only by the interval information such as space and comma or by several punctuation marks such as a question mark and an exclamation mark so that it is not easy to generate natural rhythms of people even though it is based on mass speech database. To make up for the problem, there is a way to select rhythms after processing language from a higher level information. This paper proposes a method for generating tags for controling rhythms by analyzing the meaning of sentence with speech situation information. We use the Systemic Functional Grammar (SFG) [4] which analyzes the meaning of sentence with speech situation information considering the sentence prior to the given one, the situation of a conversation, the relationship among people in the conversation, etc. In this study, we generate Semantic Speech Control Tag (SSCT) by the result of SFG's meaning analysis and the voice wave analysis.

There has been a growing enthusiasm in Korea for the early education of English as a foreign language (EFL). The present study examined the validity of the Critical Period Hypothesis in terms of the Universal Grammar (UG), in three different types of learning contexts - first language (L1), second language (SL), and foreign language (FL) learning contexts. While previous research findings in L1 and SL learning contexts suggest that UG principles and parameters are accessible to language learners only for the early years of lifetime, this article argues that their results - and even the methods - cannot be applied to EFL settings and that independent studies on the EFL context are, required. It also proposes the recent UG notion of functional categories as the most appropriate subject in the discussion of Korean EFL learners' access to UG. Findings on foreign language contexts, including the author's own, strongly indicate that UG is not sensitive to learners' starting ages in FL settings. If young children in FL contexts cannot develop their interlanguage grammar based on UG, the existing teaching methods for young children should be revised.

This paper retraces the development of Database Semantics (DBS) from its beginnings in Montague grammar. It describes the changes over the course of four decades and explains why they were seen to be necessary. DBS was designed to answer the central theoretical question for building a talking robot: How does the mechanism of natural language communication work? For doing what is requested and reporting what is going on, a talking robot requires not only language but also non-language cognition. The contents of non-language cognition are re-used as the meanings of the language surfaces. Robot-externally, DBS handles the language-based transfer of content by using nothing but modality-dependent unanalyzed external surfaces such as sound shapes or dots on paper, produced in the speak mode and recognized n the hear mode. Robot-internally, DBS reconstructs cognition by integrating linguistic notions like functor-argument and coordination, philosophical notions like concept-, pointer-, and baptism-based reference, and notions of computer science like input-output, interface, data structure, algorithm, database schema, and functional flow.
