노화로 인한 인지의 변화는 정상 노인들의 통사처리에 부정적 영향을 끼치는데 작업기억용량이 중요한 인지기능을 한다고 알려져 있다. 본 연구는 명사구 연결 전치사구의 이해에 도움이 되는 문맥을 제시할 때와 그렇지 않을 때 정상 노인과 젊은 성인이 어떻게 명사구 연결 전치사구를 처리하는지 단어별 자율조절읽기 방법을 통해 알아보았다. 또한, 이 때 어떤 인지기능이 문맥 이용을 통한 명사구 연결 전치사구의 처리능력과 관련이 있는지도 살펴보았다. 정상 노인은 읽기과제에서 문맥유무에 상관없이 젊은 성인보다 읽기속도가 느렸다. 그러나 두 그룹 모두 문맥이 존재할 때 명사구 연결 전치사구의 처리 속도가 빨랐다. 즉, 노인들의 노화로 인한 인지의 저하는 처리 속도만 느리게 했을 뿐 질적인 면에서 차이는 없었다. 문맥을 이용한 명사구 연결 전치사구 처리 시 관련된 인지기능은 교대주의력으로 나타났으며 본 연구에서는 작업기억용량의 역할은 발견되지 않았다. 이를 통해 노화가 통사처리에 끼치는 영향은 반드시 부정적인 것이 아니라 통사구조에 따라 다를 수 있으며, 통사 구문의 종류에 따라 관련된 인지기능이 다를 수 있음을 시사한다.

본 연구는 자동화된 통사 구문 분석 프로그램인 TAASSC를 활용하여 한국 대학생의 에세이에 나타난 영어능력 수준과 통사적 복잡성간의 관계를 살펴본다. 본 연구에서는 ICNALE 코퍼스에 포함된 한국인 대학생이 작성한 에세이를 분석하였고, 구 복잡성 지표와 절 복잡성 지표가 영어 수준을 얼마나 잘 예측할 수 있는지를 살펴보았다. 단계적 회귀분석 결과 구 복잡성 지표는 영어 능력 수준 변인의 8%, 절 복잡성 지표는 약 11%를 설명하는 것으로 나타났다. 따라서 절 복잡성 지표가 구 복잡성 지표보다 한국인 대학생의 영어 수준을 조금 더 잘 예측한다고 볼 수 있으며, 이는 구 복잡성 지표가 쓰기 능력 발전의 표준이 된다는 Biber 외(2011)의 연구 결과와는 상반된다.

This paper investigates the role of input frequency in the acquisition of verb argument structures based on distributional information of a corpus of utterances derived from the English CHILDES database (MacWhinney 1993). It has been widely accepted that children successfully learn verb argument structures by innate language mechanisms, such as linking rules which connect verb meanings and its syntactic structures. In contrast, an approach to language acquisition called “statistical language learning” has currently claimed that children could succeed in acquiring syntactic structures in the absence of innate language mechanisms, making use of distributional properties of the input. In this paper, I evaluate the feasibility of the statistical learning in acquiring verb argument structures, based on distributional information about locative verbs in parental input. The naturalistic data allow us to investigate to what extent the statistical learning approach can and cannot help children succeed in learning the syntax of locative verbs. Based on the results of English database analysis, I show that there is rich statistical information for learning the syntactic possibilities of locative verbs in parental input, despite some limitations in the statistical learning approach.

One main complexity of the copula constructions concerns a mismatch between morphology and syntactic constituency: the copula seems to form a morphological unit with the immediately preceding element, whereas in terms of syntax the copula appears to take this as its syntactic complement. In capturing such mismatches, we show that the copula is treated as an independent verb at the level of tectogrammatical structure (or syntax tree), whereas as a bound morpheme at the level of phonogram-matical structure (or domain tree), in terms of Dowty 1992 (or Reape 1994). This paper, adopting the notion of DOMAIN in HPSG, shows that copula constructions are a subtype of compacting-constructions. These constructions compact the domain value of the copula and that of its preceding element together into one domain unit, eventually making it inert to syntactic phenomena such as scrambling, deletion and pro-form substitution. This construction-based approach provides a clean analysis for the formation of the copula construction and related phenomena.

Shi (2000) claims that topics must be related to a syntactic position in the comment, thus denying the existence of dangling topics in Chinese. Under Shi's analysis, the dangling topic sentences in Chinese are not topic-comment but subject-predicate sentences. However, Shi's arguments are not without problems. In this paper we argue that topics in Chinese can be licensed not only by a syntactic gap but also by a semantic gap/variable without syntactic realization. Under our analysis, all the dangling topics discussed in Shi (2000) are, in fact, not subjects but topics licensed by a semantic gap/variable that can turn the relevant comment into an open predicate, thus licensing dangling topics and deriving well-formed topic-comment constructions. Our analysis fares better than Shi's in not only unifying the licensing mechanism of a topic to an open predicate without considering how the open predicate is derived, but also unifying the treatment of normal and dangling topics in Chinese,

대부분의 PC 사용자들은 늘 사용하는 몇 가지 명령만으로 컴퓨터를 조작하고 있다. 그러나 DOS명령 대신 한글 문장으로 컴퓨터를 조작한다면, 최적의 명령어를 생성해낼수 있을뿐 아니라 사용자에게 융통성을 제공할 수 있다. 이를 위하여 본 논문에서는 자연어로 입력되는 한글 문장을 형태소 분석, 구문분석, 의미분석, 개념분석을 통해 일련의 DOS명령으로 변환하는 방법을 연구하였다. 형태소 분석에서는 Tabular Parsing 이 이용되고, 구문 분석과 의미분석에서는 격문법이 이용된다. 문자의 의미는 개념망으로 표현되고 이로부터 DOS 명령어가 생성된다.

This paper proposes a basic implementation of bi-directional transition system between Korean and Japanese. The syntactic structure of Korean language is very similar to that of Japanese. In order to use the same main program for bi-directional translation, system is classified into two parts. One is directly translatable part and the other is untranslatable part by direct matching because of different structure. Solving these problems, the syntactic and semantic informations control bi-directional interpreting process and make equivalent syntactic level between two languages.

A method of quantitative electrocardiogram analysis, based on concepts drawn from syntactic pattern recognition theories, is described. The algorithm can be used for removing the Interference noises and base line drift as a filter function, and for reducing the number of points representing the digitized ECG waveform. The Parsing is performed with simple finite state automata inferred by experiments and suitable to be updated during experiment execution. Two parameters are utilized for defining the noise and these make the algorithm flexible. The examples for testing the algorithm is real ECG waveforms with noise. Some experimental results lire presented.

This paper present s a pattern generation scheme from financial charts. The patterns constitute knowledge which consists of patterns as the conditional part and the impact of the pattern as the conclusion part. The patterns in charts are represented in a syntactic approach. If the pattern elements and the impact of patterns are defined, the patterns are synthesized from simple to the more highly credible by evaluating each intermediate pattern from the instances. The overall process is divided into primitive discovery by Genetic Algorithms and pattern synthesis from the discovered primitives by the Syntactic Pattern-based Inductive Learning (SYNPLE) algorithm which we have developed. We have applied the scheme to a chart : the trend lines of stock price in daily base. The scheme can generate very credible patterns from training data sets.

This paper investigates ordering alternation phenomena in Korean using the dative construction data from Sejong Corpus of Modern Korean (Kim, 2000). The paper first shows that syntactic weight and information structure are distinct and independent factors that influence word order in Korean. Moreover, it reveals that heaviness and givenness compete each other and exert diverging effects on word order, which contrasts the converging effects of these factors shown in word orders of right-branching languages like English. The typological variation of syntactic weight effect poses interesting theoretical and empirical questions, which are discussed in relation to processing efficiency in ordering.
