The present study investigated the semantic and syntactic processes in Korean children's sentence comprehension by measuring event-related brain potentials(ERPs). The subjects were 18 right-handed, healthy native Korean children(1st graders), who were free from any hearing problems. While the children listened to the auditory sentence stimuli, ERPs were recorded with the electrodes mounted in a 'Quik-Cap' on the subject's head. The ERP data were recorded and analyzed using the NeuroScan 4.3 and EEGLABv6.03b programs. For statistical analyses, descriptive statistics, three-way repeated measures ANOVA, and t-tests were performed using a SPSS 15.0 PC program. The results indicated that semantic violations elicited a negativity (N400) ranging from 300 to 500 msec. For syntactic violations, children displayed a positivity (P600) ranging from 900 to 1,100 msec. The discovery of N400 and P600 in semantic and syntactic processes respectively, confirmed the suggestion that Indo-European and Korean languages share a common mechanism for sentence comprehension.

The purpose of this study is to investigate the adequacy of derivational approach and representational approach to syntactic theories in generative grammar. As the generative grammar is based on the derivational process of syntactic theories, it is suggested that derivational approach is more valid than representational approach. Move, Economy Principle, Local Economy and Label-free Phrase Structure in Minimalist framework support the preference of derivational approach to representational approach with the elimination of computational complexity, minimality, and label-free phrase structure. Syntactic structure is considered as the result of the interaction of the properties of lexical items containing probe and economy conditions constrained by bare output conditions. On the other hand, Pseudogapping in Lasnik(1999) is analyzed in terms of Object Shift, that is, overt raising to Spec of $Agr_o$ and the PF deletion of VP in representational approach. Hence, it is suggested that the combination of derivational and representational approaches to syntactic theories can be admitted in generative grammar.

The major goals of this paper are to identify the degree into which the meanings of 'see' verb can be extended, focusing on the extended meanings shown in the expressions that denote our instinctive actions for survival, such as eating or drinking, etc., and to clarify the doubt on whether any syntactic pattern can be associated with the meaning in the process of meaning extension of 'see' verb. For doing this task, this paper picked out 2,000 examples randomly from COCA (Corpus of Contemporary American English), in which the verb 'see' is used. This paper classified the sentences into thirteen different sentence types, according to the syntactic patterns. This research showed that these thirteen syntactic types lead us to figure out the process of the meaning extension of the verb 'see'. With this result, this paper made an attempt to provide the four steps toward the meaning extension of verb 'see'. The verb 'see' in the first step denotes the meaning of purely seeing the visualized objects. This verb in the second step expresses the shifted function, under which the agent in the subject position takes the seeing action as a secondary task in order to carry out other main task. The verb in the third step denotes the extended meanings irrelevant to the seeing action, because the sentences on this step do not contain any visualized objects. In the last step this verb functions as conventional implicature whose meaning does not contribute to the whole meaning of a sentence. In addition, this paper identified that the syntactic properties are deeply associated with the process of meaning extension of the verb 'see', and tried to formalize this relationship between the syntax and semantics within the framework of Construction Grammar based on A. Goldberg.

This paper deals with an analyzing method of the Korean syntax to implement a natural language understanding system. A matrix of the syntactic structure is derived by the structural features of the Korean language. The modificatoty and conceptual structures are extracted from the matrix and the predicate logic form is expressed by extracting the phrase, clause and conceptual structure in the analyzing process. This logic form constructs an knowledge base of the sentence and proposes the possibility of the inference.

문장이 길어질수록 구문분석의 정확률이 급격히 떨어지므로, 문장을 분할하여 각각의 분할단위로 구문분석을 수행한 후 각 구문분석결과를 합쳐 완성된 구문트리를 만드는 것이 일반적이다. 이 때 주로 절 단위로 문장이 분할되고, 각 절의 구문분석결과를 통합하게 되는데, 통합 과정에서 절-절 간의 의존관계 설정에 많은 오류가 생긴다. 이러한 절 간의 의존관계의 애매성을 해결하기 위하여, 본 논문은 기계학습을 이용하여 절-절 간의 의존관계를 분석해 본다. Support Vector Machines(SVM)을 사용하여 성능을 평가하고, 본 논문에서 실험한 방법과 기존의 방법들의 성능을 비교해 본 결과, 절-절 간의 의존관계 설정에 있어서 $8.88{\sim}15.35%$의 성능향상을 보였다.

This study aims to research into the meaning of Korean particle 'ka' and 'nun' inductively by examining the correspondences of those particles and English articles on the Korean-English parallel corpus. The correspondences were checked in three ways: semantically, syntactically and pragmatically. This study found that when the semantic or syntactic tier is not salient, the pragmatic tier is activated and particles are selected according to the pragmatic elements such as the amount of information or the change of topic. However, if the meaning of the particles is salient or if there is any syntactic motive, particles are selected in accordance with the semantic or syntactic elements. Former studies which focused on one of those three tiers cannot properly explain such correspondences on the Korean-English parallel corpus. This study shows that semantic, syntactic and pragmatic tiers hierarchically affect the selection of a particle and that the selection process is also related to speaker's intention. This dimensional analysis of particles is expected to contribute to theoretical studies and applied studies like Korean language education as well.

This study investigates issues in relation to text segmenting, in particular, line breaks in Korean language textbooks. Research on L1 and L2 reading has shown that readers process texts by chunking (grouping words into phrases or meaningful syntactic units) and, therefore, phrase-cued texts are helpful for readers whose syntactic knowledge has not yet been fully developed. In other words, it would be important for language textbooks to avoid awkward syntactic divisions at the end of a line, in particular, those textbooks for beginners and intermediate level learners. According to our analysis of a number of major Korean language textbooks for beginner-level learners, however, many textbooks were found to display line-breaks of awkward syntactic division. Moreover, some textbooks displayed frequent instances where a single word (or eojeol in the case of Korean) is split between different lines. This can hamper not only learners' learning of the rules of spaces between eojeols in Korean, but also learners' development in automatic word recognition, which is an essential part of reading processes. Based on the findings of our textbook analysis and of existing research on reading, this study suggests ways to overcome awkward line-breaks in Korean language textbooks.

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.

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.
