Pattern recognition in cognitive agents is based on (i) the uninterpreted input data (e.g. parameter values) provided by the agent's hardware devices and (ii) and interpreted patterns (e.g. templates) provided by the agent's memory. Computationally, the task consists in finding the memory data corresponding best to the input data, for any given input. Once the best fitting memory data have been found, the input is recognized by applying to it the interpretation which happens to be stored with the memorized pattern. This paper presents a fast converging procedure which starts from a few initially recognized items and then analyzes the remainder of the input by systematically checking for items shown by memory to have been related to the initial items in previous encounters. In this way, known patterns are tried first, and only when they have been exhausted, an elementary exploration of the input is commenced. Efficiency is improved further by choosing the candidate to be tested next according to frequency.

This paper investigates the nature of the discourse domain involved with focus sentences. The major theories of focus including Roothian Alternative Semantics are critically reviewed: Alternative Semantics takes a contradictory attitude toward the truth conditional aspect of free focus. The truth conditional differences are treated as a pragmatic inference, while they are captured by the semantic mechanism, that is, the alternative sets generated by focus constructions. In addition, the alternative sets are ad hoc since they are generated only for focus constructions. This paper attempts to show that the alternative sets introduced by foci in the framework of Alternative Semantics are neither necessary nor sufficient for an analysis of focus. It is argued that the domain sets simply provided by the model itself suffices for a proper analysis of focus constructions.

The diagram has a intuition and simplicity So, it is widely used in various fields in current computing environment. But, because of the absence of a standard diagram specification method, we have difficulty in exchanging the diagram data between different diagram software and besides, we spend much money and time to code diagram component, rules and semantics to which diagram would be applied. So We propose a method for defining diagram component's shapes and actions, diagram's rules and semantics using XML. And We design and implement the diagram system which execute XML document specifying diagram. In the diagram system, We can define diagram component in WISWIG manner and generate DML document automatically. So We can develop diagram system more efficiently. And by defining diagram rules using DTD, we also achieve the consistency of DTD meaning. And We propose Semantic Definition XML for specifying diagram semantics. So, diagram sentence which drawn by users could be given semantics and executed in diagram system. In this thesis, many VPL(Visual Programming Language) concepts were adopted to implement diagram system environment.

While developing a complex reactive software system. it is very important to analyze the user requirement and reflect it to the developed system. Therefore understanding the need of users precisely and promptly is the key to the successful software system development. Among several requirement specification languages, message sequence charts (MSCs), also known as sequence diagrams in UML are the most widely used scenario notation. Live Sequence Charts (LSCs) are a variant ot MSCs, characterized by its message abstraction facility and the modality of scenarios. In this paper, I define the formal semantics of LSC specification including the essential language constructs such as pre-charts, variables, assignment and conditions. The range of the formalized LSC language has been broadened, and the scope of the formalized semantics is much closer to the complete LSC specification.

The aim of thesis is to analyze dress phenomena, the semantic function and meaning of clothing were respectively on the basis of Semantics and Society by Geoffrey Leech and mentalistic semantics. To comprehend the actual clothing behaviour better, the pictures taken on the streets were used, including all kinds of the western-style and the traditional Korean costumes in Korea. The followings are the findings of the analysis. A in language, the semantic functions of the clothing are the informational, the expressive, the directive, the aesthetic, and the phatic functions. They communicate operating simultaneously. The clothing is the mentalistic semantics.

Scheduling problems which determine the sequence of jobs are one of the Important issues to many industries. This paper deals with a single-machine job sequencing problem which has complex constraints and an objective function. To solve the problem, an expressive constraint description language and an automatic code generator are developed for our scheduling system. The user just needs to describe the scheduling problem using the constraint description language that allows to express both quantitative and qualitative constraints as well as an objective function in real world semantics. Then, a complete scheduling program based on constraint satisfaction technique is automatically generated through the code generator. Advantage of this approach is that models of the scheduling problems are easily developed and maintained because models ore formulated by using the language which reflects real world semantics.

In this paper, I attempt to define the semantics of cikum 'now' in Korean. To define it precisely, we need to look at how it interacts with different aspectual classes of verbs and with the semantics of tenses and aspects. In doing this we need to define the semantics of tenses and aspects. Here we run into the question of whether ess is a tense marker or an aspect marker. I assume that it is ambiguous. There are still cases where it is not clear whether ess is used as a tense marker or an aspect marker in an actual sentence. I discuss two such cases: one in which it is used with verbs like tochakha 'arrive' which have no salient resulting states, and one in which a state verb is used with cikum-kkaci 'until now'. The semantics of cikum can be defined differently depending on whether ess is a tense or an aspect. By discussing ko iss, which is an imperfect marker, I conclude that cikum means ${\lambda}P{\lambda}i[u{\subseteq}i{\wedge}P(i)]$, that is, a relation between a set of times which include an utterance time and a set of properties of times.

Sign languages, commonly used in aurally challenged communities, are a kind of visual language expressing sign words with motion. Spatiality and motility of a sign language are conveyed mainly via sign words as predicates. A predicate is modified by an adverbial phrase with an accompanying change in its semantics so that the adverbial phrase can also affect the overall spatiality and motility of expressions of a sign language. In this paper, we analyze the semantic features of adverbial phrases which may affect the motion-related semantics of a predicate in converting expressions in Korean into those in a sign language and propose a system that generates corresponding animation by utilizing these features.

Language is not abstract. We use language to communicate out thoughts and emotions. Films are the most public form of arts, where language is all essential part; however, there have been, if any, few films the main theme of which is language. Although language may not be the main theme of films, we can find many kinds of information relating to language and linguistics by careful examination. In reference to some films, we can talk about subjects in the fields of theoretical linguistics such as phonetics, phonology, morphology, syntax, semantics, and pragmatics. In addition, subjects in applied linguistics such as sociolinguistics and computational linguistics may be discussed with reference to other films.
