This paper compares different uses of downgraders by Korean English speakers (KES) with those by American English native speakers (AENS) in their requestive e-mail. Three different situations in which social power and distance were controlled were set up to examine and compare the participants' politeness strategies in requestive e-mail. It was found that the KESs' use of downgraders appeared differently from the AENSs' use qualitatively and quantitatively across three situations. The AENSs used downgraders almost three times as more, resulting in a much more mitigated and polite effect in requests. The AENSs' requests were mostly modified by syntactic modifiers, such as aspect, tense, conditional, and consultative devices. On the other hand, the KESs' requests were modified mostly by politeness markers and conditionals in a limited number of requests.

Automatic language translation has greatly advanced due to the increased user needs and Information retrieval in WWW. This paper utilizes the integrated knowledge bases of noun and verb networks for automatic translation of ambiguous words in the Korean sentences, through the selectional restriction relation in the sentences. And this paper presents the method to verify validity of Korean noun semantic networks that are used for the construction of the selectional restriction relation by applying the networks to the syntactic and semantic properties Integration of Korean Noun Networks into the SENKOV system will provide the accurate and efficient knowledge bases for the semantic analysis of Korean NLP.

This study was designed to determine what components of spoken language have been relatively neglected in the teaching of listening comprehension in Korea and to suggest a model of listening process. Two types of tests were undertaken using spoken and written forms of English with secondary school teachers of English and college students. Findings: Hearing power has been generally neglected in the teaching of listening comprehension. Hearing power which can be thought as an active process is defined as an ability to transfer the sequence of discrete phonetic segments without word boundary into the sequence of words in phonemic representations by using both nonlinguistic factors and linguistic factors including perception rules based on phonetics and phonology. Vocabularies, hearing-speaking power, syntactic structures and idiomatic expressions are to be taught for spoken English. A model of listening process was suggested and discussed.

This paper describes procedures to model and synthesize emotional speech in a multimedia environment. At first, procedures to model the visual representation of emotional speech are proposed. To display the sequences of the images in synchronized form with speech, MSF(Multimedia Speech File) format is proposed and the display software is implemented. Then the emotional speech sinal is collected and analysed to obtain the prosodic characteristics of the emotional speech in limited domain. Multi-emotional sentences are spoken by actors. From the emotional speech signals, prosodic structures are compared in terms of the pseudo-syntactic structure. Based on the analyzed result, neutral speech is transformed into a specific emotinal state by modifying the prosodic structures.

The limited capacity model has been used to explain linguistic interactions and trade-offs that occur in children's speech. The purpose of the present investigation is to explore the interrelationship of MLU (as an index of syntactic development) and fluency in the spontaneous speech of normal children. Twenty normal children's (ten girls and ten boys, aged 36-48 months) spontaneous speech samples were obtained during free-play interactions with their mothers or other adults. The results indicated that the MLU of disfluent utterances were significantly longer than that of fluent utterances. Also, disfluencies occurred more frequently in longer utterances than in shorter utterances. In addition, the utterances where disfluencies occurred more than 2 times were longer than those where disfluencies occurred once. These results imply that the increase of MLU appear to affect not only the occurrence of disfluent utterances, but also the number of disfluencies within the utterances. In other' words, these findings show that there are trade-off effects between MLU and fluency. This is discussed within a limited capacity framework.

The current study reports the results from a cross-modal naming experiment investigating the effects of a prosodic boundary location on the comprehension of ambiguous dative NPs in Korean (Yeongmi-ka Ceonghi-eykey norae-rul pwulecwu-n pwuin-ul ${\cdots}$). The underlined dative NP, Ceonghi-eykey, can temporarily be attached to the embedded rel-marked verb, pwulecwu-n ('sing-rel') or to the matrix verb to appear later. Participants heard sentence fragments manipulated for the location of Intonation Phrase boundary (the biggest prosodic boundary in the model of Seoul Korean) and right after that, had to name visually presented naming targets, which resolve the ambiguity of dative NPs. The prosodic manipulation did not result in difference in naming time, suggesting that the location of a prosodic boundary failed to influence the way Korean listeners interpreted ambiguous dative NPs. Possible reasons for the null effect were discussed.

In this pater, we present a syntactic software complexity measure based on program control structure using Petri Nets. Since control structure in program may be segregated by three structures such as sequence, condition and iteration structures, we are proposed a structured complexity measure based on program control structure after represented by Petri Nets. Finally, we compare our result with other measures of program complexity.

하위범주화는 술어와 보어간의 의존 관계를 정의하는 언어정보로서 다의어 태깅이나 이 외에 자연어처리의 다양한 곳에 이용될 수 있다. 그러나 하위범주화에서 다루는 필수논항은 격조사로 표현되어 실제로 한국어에서 자주 나타나는 보조사는 여기에 포함되지 않는다. 이런 문제 때문에 하위범주화네 나타난 격조사만을 그대로 이용하려고 하면 재현율에 큰 문제가 발생하게 된다. 본 논문에서는 문장에서 격조사 대신 보조사가 사용되었을 때 하위범주화의 필수논항으로 인정할 수 있는 방법을 제시하고, 특히 보조사에 적용할 경우에 생기는 이점을 실험으로 증명한다.

In this paper, a new method of Hangul recognition is proposed to solve the problems of misrecognition owing to the contacts of FCEs (Fundamental Character Elements) in a Hangul pattern. Structures of FCFs are represented with PAG(Programmed Array Grammar) to recognize an input pattern on 2-D. array of pels., and the unnecessary deformation of the conventional approach can be eliminated by using PEACE parsing which extracts primitives and computes attributes in the course of analyzing the structure of an input pattern. Also, primitive transformation at contacts can afford to confirm all the possible structures of an input pattern and solve the problem of misrecognition owing to the contacts of FCEs. The recognition rate of proposed method for printed Hangul characters shows 96.2% for 1978 Gothic-letters and 92.0% for 1920 Myng-style-letters, respectively.
