An example-based dialogue system tries to utilize many pairs which are stored in a dialogue database. The most important part of the example-based dialogue system is to find the most similar utterance to user's input utterance. Modality, which is characterized as conveying the speaker's involvement in the propositional content of a given utterance, is one of the core sentence features. For example, the sentence "I want to go to school." has a modality of hope. In this paper, we have proposed a modality classification system which can predict sentence modality in order to improve the performance of example-based dialogue systems. We also define a modality tag set for a dialogue system, and validate this tag set using a rule-based modality classification system. Experimental results show that our modality tag set and modality classification system improve the performance of an example-based dialogue system.

The purpose of this paper is to identify the workings of intonation realized in the endings through the spoken language. To achieve this objective, this paper has analyzed 300 minutes of spontaneous speech by women from Seoul and discussed the meanings of modality and their relationship with intonation. Intonation functions significantly in polysemous modal endings in epistemic and act modality. Epistemic modality is usually expressed through indirect and soft intonations such as L:, M: and LH, whereas act modality is expressed through direct and strong intonations such as H, HL and LHL. Intonation appears to be related to the Certainty degree of information, rather than classification of modality, Lengthening relate to indirectness, H with uncertainty, L with statements or affirmation, and HL and LHL relates to assertive attitude. This paper is significant as it has overcome the abstractness of existing modality studies and has engaged in objective and comprehensive analysis with actual spontaneous speech data.

We present modality conversion as an effective means for QoS management. We show that modality conversion, in combination with content scaling, would give a wider range of adaptation to support QoS at media level. Here, we consider modality conversion with respect to resource constraint and human factor. To represent modality conversion as well as content scaling, we present the overlapped content value (OCV) model that relates the content value of different modalities with resources. The specification of user preference on modality conversion is divided into qualitative and quantitative levels. The user preference is then integrated into the OCV model so that modality conversion correctly reflects the user's wishes. For the conversion of multiple contents, an optimization problem is formulated and solved by dynamic programming. The experiments show that the proposed approach is efficient to be applied in practice.

The purpose of this paper is to make a sentence systemic within the category of structural grammar for the modality in which a speaker expresses his attitude. It is the priority of a language to communicate meaning. By eliminating the theoretical description of traditional grammar, this paper also aims to illustrate the concepts of nine modal verbs through a systemic network. The concept of modality includes both the epistemic and the deontic characteristics of modality. Epistemic modality is associated with either knowledge or belief on the part of a speaker who gives his own judgments about the state of affairs, events, or actions. However, deontic modality is related to either the possibility or the necessity of acts that a speaker performs to give permission or fulfill an obligation. In conclusion, all the subsystems are described within the framework of the systemic network, with the intention of including all the potential options of the semantic functions available in a situation.

Purpose : The main purpose of this study was to investigate the effect on Balance Ability of Knee Osteoarthritis(OA) by modality. Methods : The subjects were consisted of 30 women patients with knee OA. All subjects were randomly assigned to modality group. Each group had a treatment for 45 minutes per day and three times a week during 8 weeks period. Was used to measure recovery or worse of patient's condition, muscle assessment questionnaire(MAQ) was used to measure patient's muscular strength, Endurance, coordination/balance, KWOMAC was used to pain, stiffness, and physical function, and BPM was used to measure velocity, anterior-posterior. Results : This study results in following conclusions. 1. MAQ score was significantly decreased in modality group(p<.05). 2. KWOMAC score was significantly decreased in modality group(p<.05). 3. BPM were score was significantly decreased in modality group(p<.05). Conclusions : From this result the modality treatment retrogression characteristic will be effective in treatment of patient.

The purpose of the present study was to investigate the age-related differences in recall and to assess effects of presentation modality, encoding condition and cue modality on recall in terms of encoding specificity principles and dual-coding theory. Eighty children in each of 3grades(first, third and fifth) were presented a 30-item set of pictures or words on cars for recall in a study-test procedure. The experiment was designed as a 3(age) x 2(presentation modality:picture or word) x 2(encoding condition:random or category) x 2(cue modality:picuture or word) factorial design. Statistical analyses were with four-way ANOVA and $Scheff\acute{e}$ test. It was concluded from these results that when the stimulus was presented by pictures, encoded by category and the cues were also presented by pictures, recall increased in all ages. These results were interpreted in terms of encoding specificity principles and dual-coding theory.

This letter presents a prediction model for sentence-final intonations for Korean conversational-style text-to-speech systems in which we introduce the linguistic feature of 'modality' as a new parameter. Based on their function and meaning, we classify tonal forms in speech data into tone types meaningful for speech synthesis and use the result of this classification to build our prediction model using a tree structured classification algorithm. In order to show that modality is more effective for the prediction model than features such as sentence type or speech act, an experiment is performed on a test set of 970 utterances with a training set of 3,883 utterances. The results show that modality makes a higher contribution to the determination of sentence-final intonation than sentence type or speech act, and that prediction accuracy improves up to 25% when the feature of modality is introduced.

이용자의 감성은 그 어느 때보다 기업, 정부 그리고 개인 간의 소통에서 중요한 변수로 인식된다. 특히 수많은 연구에서 이용자의 감성을 파악하는 방법으로 음성 톤, 속도, 얼굴 표정, 몸의 이동 방향과 속도, 제스쳐 등이 사용된다. 다중 모달리티는 단일의 모달리티보다 정확도가 높은 반면 멀티 센싱에 따른 인식률 한계와 데이터 처리 부하 그리고 센싱된 값을 추론하는 우수한 알고리즘이 요구된다. 즉 다중 모달리티는 각 모달리티의 개념, 속성이 상이하여 인간의 감성값이라는 표준화된 값으로 전환하는데 오류가 발생할 수 있다. 이 문제를 해결하기 위해 다중 모발리티 중관계망 분석, 문맥 파악, 디지털 필터 등의 기술을 이용하여 이용자에게 우선 순위를 갖는 감성 표현 모달리티를 추출할 필요가 있다. 특정 상황에 우선 순위를 갖는 모달리티와 그 주변을 에워싼 다른 모발리티를 암묵 값으로 처리하면 감성 인식에 있어 컴퓨터 자원의 소비 대비 견고한 시스템을 구성할 수 있다. 본 연구 결과, 암묵 데이터를 활용하여 다중 모발리티 중 가중치를 어떻게 부여할지에 대하여 제안하였다.

CBIR is an effective tool to search and extract image contents in a large remote sensing image database queried by an operator or end user. However, as imaging principles are different by sensors, their visual representation thus varies among image modality type. Considering images of various modalities archived in the database, image modality difference has to be tackled for the successful CBIR implementation. However, this topic has been seldom dealt with and thus still poses a practical challenge. This study suggests a cross modality CBIR (termed as the CM-CBIR) method that transforms given query feature vector by a supervised procedure in order to link between modalities. This procedure leverages the skill of analyst in training steps after which the transformed query vector is created for the use of searching in target images with different modalities. Current initial results show the potential of the proposed CM-CBIR method by delivering the image content of interest from different modality images. Despite its retrieval capability is outperformed by that of same modality CBIR (abbreviated as the SM-CBIR), the lack of retrieval performance can be compensated by employing the user's relevancy feedback, a conventional technique for retrieval enhancement.

This study focuses on Gilbert Simondon's individuation theory, a core concept of his technological philosophy, and spatial modality in interactive space as the schema of interactive operation. The study examines spatial modality as the technology of an interaction-enabler that has archi-semiotic characteristics in the designed space by aspects of examples. They are based on ideas and properties of a combined environment and the concept of information, which form Simondon's individuation theory. In the process of technological individuation, spatial modality has the characteristics of archi-semiotics from a combined environment and information. The first of the three properties is representation through semiosis and the information surface. Second is the context by relation works and perception, and third are the symbolic aspects, which could create Placeness by meaning. Combining meaningful constructive and deconstructive spaces could result in space for interactive communication. Spatial modality makes it possible to interact with users and spaces. In fact, it could have a particular semiotic mode of address and become a semiotic and contextual base. As a basic investigation of spatial modality, this study will contribute to interactive space design research.
