  • CDSS provides clinical doctors with knowledge to be required when they diagnose or make decision about treatment strategy. Arden Syntax is one of the language with which we write MLM that is a component of CDSS. It was designated as a standard by HL7/ANSI. ArdenML is an XML version of Arden Syntax. In this paper we propose a tool which translates Arden Syntax MLMs into ArdenML MLM. To this end we first defines the corresponding relation between two languages. Next we presents a modified version of Arden Syntax grammar to improve performance of lexical analysis and minimize parsing conflicts. Finally we presents syntax and semantics gaps between the both languages, which are a structural representation problem, a data type problem, and a disrelation problem. Our translator resolves such issues and generates exact ArdenML codes for an arbitrary Arden Syntax MLM.

  • This study explores the lexical-semantic structure of derived causative verbs in Korean based on Pustejovsky(1995)'s Generative Lexicon Theory (GL). Morphological causative verbs are derived from their root stems by affixing ‘-i, -hi, -li, -gi’ in Korean and the meanings of derived predicates are closely related to the meanings of their root verbs. In particular, the change of the ARGUMENT STRUCTURE by morphological derivation leads to the change of the EVENT STRUCTURE. The ARGUMENT STRUCTURES of derived causative verbs include a causer argument, which is added to the ARGUMENT STRUCTURE of their root verbs by means of the causative derivation. Their EVENT STRUCTURE has a headed process related to a causer and its result is the event which their root verbs denote. This approach can also suggest that the (in)directness of causative is dependent on is the semantics of its root verb.

  • This paper argues for a need to adopt a conceptually radical approach to zero anaphora resolution in Korean. It is shown that a number of apparently conflicting constraints, mostly motivated by lexical, syntactic, semantic, and pragmatic factors, are involved in determining the referential identity of zero pronouns in Korean. It is also argued that some of the major concepts of Optimality Theory can provide a good theoretical framework to predict the antecedents to zero pronouns in general. A partial formalization of 07-based constraints at the morpho-syntactic and lexico-semantical level is provided. It is argued that the lexico-semantic restrictions on adjacent expressions play the most important role in the anaphora resolution process along with a variant of the binding principle, formulated in semantic terms. Other pragmatically motivated constraints that incorporate some important intuitions of Centering Theory are proposed too.

  • This paper examines existing approaches to exceptive constructions, which typically serve to maintain the use of universal quantifiers by diminishing the domain quantified over. It places a particular focus on constructions involving Korean oyey, Dutch behalve, and English apart from, other than, and aside from. These lexical items all share an interesting semantic property that they mean either 'except' or 'besides' depending upon their linguistic contexts, but they have largely been ignored in the literature of exceptive constructions. An observation is made that the two meanings of the ambiguous exceptive words are in complementary distribution with respect to types of quantifiers and that they are not an isolated fact. Based on this, a unifying formal semantic analysis is attempted for the constructions.

  • The aim of this paper is twofold: to identify two types of even if concessive conditionals, standing-ifs and introduced-ifs (Bennett 1982) in terms of whether the truth of the consequent is 'entailed' (the consequent-entailment problem in terms of Lycan 2001); and to analyze these two types of concessive conditionals in a compositional way. Here we argue that, following Guerzoni and Lim (2007), even if conditionals can be analyzed as the cases where even gets its focus in conditionals. We also argue that the consequent-entailment problem can be accounted for in a compositional way if we identify the focus as well as the scope of even in conditionals correctly. We further argue that the analysis presented in this paper supports the scope theory of even, among two theories of even previously proposed in various works. We also consider the possibility where concessive conditionals without even can be analyzed as an extension of the analysis proposed in this paper.

  • 기계학습 기반 문서범주화 기법에 있어서 최적의 자질을 구성하는 것이 성능향상에 있어서 중요하다. 본 연구는 학술지 수록 논문의 필수적 구성요소인 저자 제공 키워드와 논문제목을 대상으로 자질확장에 관한 실험을 수행하였다. 자질확장은 기본적으로 선정된 자질에 기반하여 WordNet과 같은 의미기반 사전 도구를 활용하는 것이 일반적이다. 본 연구는 키워드와 논문제목을 대상으로 WordNet 동의어 관계 용어를 활용하여 자질확장을 수행하였으며, 실험 결과 문서범주화 성능이 자질확장을 적용하지 않은 결과와 비교하여 월등히 향상됨을 보여주었다. 이러한 성능향상에 긍정적인 영향을 미치는 요소로 파악된 것은 정제된 자질 기반 및 분류어 기준의 동의어 자질확장이다. 이때 용어의 중의성 해소 적용과 비적용 모두 성능향상에 영향을 미친 것으로 파악되었다. 본 연구의 결과로 키워드와 논문제목을 활용한 분류어 기준 동의어 자질 확장은 문서 범주화 성능향상에 긍정적인 요소라는 것을 제시하였다.

  • The purpose of this study is to research and systematize Jeju dialectal words about Jeju traditional housing culture and study them on the basis of lexical semantics. Vocabularies related to the names of the traditional thatched-roof house and its partial names, thatching, supplementary facilities, housing culture, etc. were categorized after recording in an ethnographic way from Seongeup folk village which is Important Folklore Material no.188, and studied them linguistically. Informants are fore people who were born and bred in Seongeup-ri and they are over 70. They have a lot of experiences building thatched-roof houses from a young age. There are 9 different categories - the kind of the house, partial names, exterior space, materials, tools, words about actions, doers, units, and folklore. Some new words related to Jeju traditional housing, which had not been in the list of Korean dictionary, could be introduced as a result of the study. For example, rice which are made when doing earth work is called Heukppap and adzes used to sharpen stones are called Dolchagui. The finding of These new words hopefully contribute to the promotion of Korean language as well as enrich vocabulary on housing. Furthermore, the collected vocabularies and oral materials could be used as important educational materials to comprehend Jeju traditional housing culture.

  • 자연언어처리에 있어서 병렬구문은 분석의 복잡성, 단어의 애매성, 서술어 생략 등에 따른 처리의 어려움을 내포하고 있다. 본 논문에서는 한국어에서 발생하는 병렬문의 통사적 특징을 능력문법 (competence grammar)의 입장에서 접근하고 분석된 결과를 기반으로 하여 한국어 병렬문 해석을 위한 결합범주문법 (Combinatory Categorial Grammar)을 제안한다. 제안된 결합범주문법을 사용해서 병렬문에 대한 각각 다른 수준의 통사적, 의미적, 문맥적 정보들이 사전에 어휘적으로 통합될 수 있고 통합된 정보를 이용하여 통사적, 의미적, 문맥적 분석들이 각각 다른 수준의 처리를 거치지 않고 동시에 점진적으로 유도될 수 있음을 보인다. 유도된 정보들을 통해 일반적으로 한국어 병렬문의 주된 기능이라고 생각되는 두 문장이 가지는 정보를 대조, 비교하는 기능이 표현될 수 있음을 보인다. 말뭉치를 분석하여 병렬문이 한국어 처리에서 차지하는 비중과 제시한 문법으로 처리할 수 없는 문형들에 대한 논의를 제공한다.
