In systemic grammar an English clause is analysed simultaneously from the point view of its ideational function, interpersonal function and textual function. This study deals with only the ideational function of the three functions, which accounts for the underlying content of a clause. Transitivity is the subsystem of the ideational function. It specifies the different types of process that are recongnized in the language and the structures by which they are expressed. The purpose of the paper is to describe the transitivity of English clause on the basis of systemic approach. For this we analyzed the three subsystems of transitivity which are physical process, mental process and relational process in the form of features. And we described the sets of the features of the three different types of process in English clause in the framework of the system network.

This paper discusses constraints on grammaticalization, a primarily diachronic process through which lexical elements take on grammatical functions. In particular, it will argue that two constraints on this process, namely Persistence and Lwering, explain the different distributional patterns of time-relationship adverbs in Japanese, Korean, English and German. Furthermore, it will suggest that the distributional difference between Japanese and Korean time-relationship adverbs is not an isolated phenomenon but is a reflection of the overall semantic typological differences between the two languages in the sense of Hawkins (1986).

I argue that the so-called psychological predicates like komapta ′thankful,′ mwusepta ′fearful,′ silhta ′loathsome,′ or kulipta ′missing′require a nominative subject and a locative or dative complement, challenging the claim, a conventional wisdom originated from Kuno(1973), that they are two-place "transitive adjectives" requiring a nominative direct object, I also show that those adjectives are subject to having the locative-dative complement extracted, which is ultimately realized as a focused subject or a topic. Thus, in this type of double nominative constructions, the first nominative is a focused subject, and the second nominative forms an embedded clause with the psychological predicate, which functions as the predicate of the whole sentence.

A new model management framework is proposed to accommodate wide-spreading algebraic modeling languages (AMLs), and to facilitate a full range of model manipulation functions. To incorporate different modeling conventions of the leading AMLs (AMPL, GAMS, and SML) homogeneously, generic model concepts are introduced as a conceptual basis and are embodied by the structural and operational constructs of an Object-Oriented Database Management System(ODBMS), enabling the framework to consolidate components of DSSs(database, modelbase, and associated solvers) in a single formalism effectively. Empowered by a database query language, the new model management framework can provide uniform model management commands to models represented in different AMLs, and effectively facilitate integration of the DSS components. A prototype system of the framework has been developed on a commercial ODBMS, ObjectStore, and a C++ programming language.

In this paper, in first we show a main concept of Ada language and the architectures and functions of transport model for OSI, and than represent the possibility of describing the transport interface using Ada language. It is gived a following result. As we specify communication protocol using the Ada, we can to create of program for processing the communication protocol or for processing protocol itself. It is know to us to represent the effect debugging of softeware.

본 논문은 보조사로 인해 야기되는 한국어 미지격의 구문관계 중의성 해소를 위한 새로운 기법을 제안한다. 기존의 연구는 수작업으로 얻어진 동사의 의미적 선택 제약을 사용하는 방식과 단어 간의 공기패턴과 빈도를 어휘 레벨에서 추출하여 중의성을 해소하는 방식으로 나뉠 수 있다. 본 논문은 말뭉치에서 어휘 레벨이 아닌 개념패턴과 격의 분포 값을 자동으로 추출하여 미지격의 구문관계를 결정한다. 개념패턴과 용언의 격 분포 정보를 적용하여 구문분석 단계에서 실험한 결과, 본 논문이 제안한 방법은 92%의 미지격 결정 정확율을 보였다. 개념패턴은 지식의 저장공간을 줄이고 격 결정 범위를 확장할 수 있기에 범용 구문분석 시스템으로의 확장을 가능하게 한다.

This study investigates the semantic and prosodic properties of the so-called contrastive topic. We posit two informational primitives, namely, topical feature [+-T] and focal feature [+-F], from which four different informational categories, i.e., [+T, +F], [+T, -F], [-T, +F], and [-T, -F], are yielded. It is proposed that the informational category of contrastive topic has focal property [+F] as well as topical property [+T]. Based on the semantic approach that regards the function of [+F] as identificational predication and that of [+T] as forming a semantic conditional clause, it is shown that the semantic function of contrastive topic, which is specified as [+T, +F], is the combination of these two functions, i.e., identificational predication in a semantic conditional clause. This is supported by a scrutinized exploration of the prosodic pattern of English contrastive topic.

In the conventional systems, a human must have knowledge of machines and of their special language in communicating with machines. In one side, it is desirable for a human but in another side, it is true that achieving it is very elaborate and is also a significant cause of human error. To reduce this sort of human load, an intelligent man-machine interface is desirable to exist between a human operator and machines to be operated. In the ordinary human communication, not only linguistic information but also visual information is effective, compensating for each others defect. From this viewpoint, problem of translating verbal expressions to some visual image is discussed here in this paper. The location relation between any two objects in a visual scene is a key in translating verbal information to visual information, as is the case in Fig.l. The present translation system advances in knowledge with experience. It consists of Japanese Language processing, image processing, and Japanese-scene translation functions.

Some sentential adverbials in English, especially those which introduce evidentiality (hereafter evidential adverbials), such as apparently, purportedly, reportedly, and allegedly, exhibit what we call 'the perspective shift' in interrogatives: they are interpreted from the speaker's perspective in declaratives, but are interpreted from the addressee's perspective in interrogatives. To account for this phenomenon, we argue that English evidential adverbials are functions taking a proposition as its argument and returns a character in the sense of Kaplan (1989). We further show that, with this assumption, the perspective shift of evidential adverbials in interrogatives can be explained within the rather standard semantics of interrogatives (Hamblin 1973, among others) and of indexicals (Kaplan 1989).

This paper describes several approaches to transform a speaker's individuality to another's individuality using frequency warping between bilingual formant frequencies on different language environments. The proposed methods are simple and intuitive voice conversion algorithms that do not use training data between different languages. The approaches find the warping function from source speaker's frequency to target speaker's frequency on formant space. The formant space comprises four representative monophthongs for each language. The warping functions can be represented by piecewise linear equations, inverse matrix. The used features are pure frequency components including magnitudes, phases, and line spectral frequencies (LSF). The experiments show that the LSF-based voice conversion methods give better performance than other methods.
