This paper presents the observation that negative alternative questions across languages can be formed only when negation has not been inverted (Han (1999)), and proposes to derive this fact from the effects of Focus on negation and the LF-syntax of yn-questions. Although the questions in (1) have the same components (they both contain the proposition expressed by John drank coffee or tea plus negation), they do not have the same interpretation. (1b) has either a yn-question reading or an alternative question (alt-) reading. Under, the yn-reading, the possible answers are Yes, John drank coffee or tea and No, John did not drink coeffer or tea, John didn’t drink one of them, and the possible answers are John did not drink coffee and John did not drink tea (see Karttunen (1977), Larson (1985), Higginbotham (1993) on the semantics of alt-questions). (la), on the other hand, has only the yn-reading.

The purpose of this paper is to defend Kripke's theory of truth from Simmons' objection. First after introducing various sorts of the liar paradox, briefly I explain Tarski's attempt to solve the puzzle. Then, I outline Kripke's solution by using the concept of 'fixed point'. Simmons offers an interesting objection against Kripke's solution. He uses a diagonal argument in his attack to Kripke's idea. I claim that Simmons seem to use 'exclusion negation' in refuting Kripke. I think, however, there is an alternative interpretation, which is 'choice negation'. With using choice negation, I maintain that Kripke's theory of ruth can be defended from Simmons' objection.

In this study, children with MR were compared with normal children in overall production rate and production types of six semantic categories of negation. For this purpose, 10 children with MR and another 10 language-age matched normal children were selected. The results of this study were as the following: First, the children with MR showed significantly low overall production rate, compared with normal children. Two groups demonstrated signifiant differences in denial, disability, ignorance, prohibition and rejection except nonexistence. Second, in production type, the children with MR tended to use more gestures, and in comparison, normal children used more 'mixed types'.

In this paper, we address two questions concerning negative imperatives in Korean: (i) what is the morpho-syntactic nature of mal in negative imperatives\ulcorner; and (ii) why is it impossible to form negative imperatives with short negation an\ulcorner We will argue that the clause structure of imperatives include a projection of deontic modality and a projection of imperative operator encoding illocutionary force, and that oaf is a lexicalization of long negation and deontic modality. We then propose that a negative imperative with short negation is ruled out because such construction maps onto incoherent interpretation which can be spelled out as I direct you to bring about a negative state or a negative event.

This study investigates the developmental process of Korean postverbal negation in a Korean-English bilingual child. The purposes of this study are firstly to find both common and divergent paths in the development of Korean postverbal negation in terms of both syntactic development and pragmatic uses of postverbal negation; and secondly to investigate explanations for the special pattern of development observed. The data were collected from one bilingual child (R) who is simultaneously acquiring two languages, Korean and English over two years between the ages of 5;00 and 700 (years; months). The data collection was carried out in four periods in two different environments: Periods I and III in Australia, Periods II and IV in Korea. The development of postverbal negation showed that when R was in Australia, she employed both L1 and L2 learning mechanisms, while when she was in Korea, she employed L1 learning mechanisms. The results reveal that L1 and L2 mechanisms are not basically different because R shows both forward and backward developmental features in conjunction with the two different language environments: Korea and Australia.

The purpose of this paper is to get characteristics about Korean negative sentences in the 17th century. In this paper used method is to classify and collect statistics of negative sentences in the 17th century Korean literatures, then to reclassify according to morphological characteristics of predicates. The subjects of analysis are 'ani'(don't)' and 'mos(can't)' negative sentences except for 'malta(forbid)' negative sentences.

In this paper we present a pair of operators (t-norm, t-conorm) dual with a strong negation with n-threshold $a_1,\;{\ldots}, a_n\;{\in}(0,1),\;a_1\;<\;a_2\;<\;{\ldots}\;<\;a_n$. In this way we obtain an extension of operators with threshold, that are obtained for n = 1. The new pair is obtained from given one.

${\bot}$It is often said that in a purely formal perspective, intuitionistic logic has no obvious advantage to deal with the liar-type paradoxes. In this paper, we will argue that the standard intuitionistic natural deduction systems are vulnerable to the liar-type paradoxes in the sense that the acceptance of the liar-type sentences results in inference to absurdity (${\perp}$). The result shows that the restriction of the Double Negation Elimination (DNE) fails to block the inference to ${\perp}$. It is, however, not the problem of the intuitionistic approaches to the liar-type paradoxes but the lack of expressive power of the standard intuitionistic natural deduction system. We introduce a meta-level negation, ⊬$_s$, for a given system S and a meta-level absurdity, ⋏, to the intuitionistic system. We shall show that in the system, the inference to ${\perp}$ is not given without the assumption that the system is complete. Moreover, we consider the Double Meta-Level Negation Elimination rules (DMNE) which implicitly assume the completeness of the system. Then, the restriction of DMNE can rule out the inference to ${\perp}$.

Previous studies on opinion mining and sentiment analysis have supposed that the polarity and value of an emotional word is reversed when a negation word is attached. However, there are no quantitative studies on how much the polarity is changed when a negation word is following. Therefore, we measured the valence and arousal dimensions for Korean emotional words and their negations. Consequently, the polarity of valence and arousal was reversed on their intermediate level. Also, the value was reduced by about 30% to 50%. We propose this result as a guideline for processing negation words for studies on opinion mining and sentiment analysis.

Mood classification of blog text is an interesting problem, with a potential for a variety of services involving the Web. This paper introduces an approach to mood classification enhancements through the normalized negation n-grams which contain mood clues and corpus-specific term weighting(CSTW). We've done experiments on blog texts with two different classification methods: Enhanced Mood Flow Analysis(EMFA) and Support Vector Machine based Mood Classification(SVMMC). It proves that the normalized negation n-gram method is quite effective in dealing with negations and gave gradual improvements in mood classification with EMF A. From the selection of CSTW, we noticed that the appropriate weighting scheme is important for supporting adequate levels of mood classification performance because it outperforms the result of TF*IDF and TF.
