Then, it is demonstrated that the representation of roles is rather complex and error-prone in these approaches. Especially, the constraints among roles in the same context cannot be expressed by the current web ontology language （OWL）. To solve these problems, a novel model of role is presented and a corresponding ontology language is provided for representing this model. The key idea underlying the solution is that a role should be regarded as an element of a certain context and a context as a structured thing which is comprised of some internal elements. The structure of context possesses inherent modularity and local semantics, whereby the representation of roles and context is significantly simplified.展开更多

In order to resolve the embedding problem, context information of a graph production in the CAGG is represented in the form of context attributes of the nodes involved. Moreover, several properties of a set of confluent CAGG productions are characterized, and then an algorithm based on them is developed to decide whether or not a set of productions is confluent, which provides the foundation for the design of efficient parsing algorithms. It can also be shown through the comparison of CAGG with several typical context-sensitive graph grammars that CAGG is more succinct and, at the same time, more intuitive than the others, making it more suitably and effortlessly applicable to the specification of visual languages.展开更多

Among strong classical philologists, 1 was the only student whose understanding of metaphysics had been based on Avicenna. After a while 1 found myself amid audiences beforehand precluded to compromise milestones of mine. But on the contrary, I embarked to reread both of the Avicenna and Aristotle from entirely different angle again. Inquiring in the concept of Being in both of the Aristotle and Avicenna was the first candidate of my decision. This paper is the result of mentioned concern. Aristotle＇s equivalence between the question of ＂what substance is＂ rendered to the question of ＂what being is＂ in addition to spelling out the implications of this observation done by Avicenna--basing on his own metaphysics---constitutes the body of my paper.展开更多

The earlier Prescriptive and Descriptive Schools might have set the pace for this controversy but the present dilemma is much deeper. Learners and even teachers are sometimes at quandary as to how to proof that a particular word belongs to a particular class. This is because a word may sometimes belong to several classes, in context as in the word ＂watch＂ which can belong to different classes. This paper therefore tries to provide answers to the problem of word class classification by using a morphological and syntactical evidence to prove that English words follow a particular range of inflections and belong to strictly ordered particular categories and do not change their class arbitrarily. This is in line with the natural perfect order of homogeneity in creation which precludes a specie from merging effectively with another specie without having to undergo some fundamental changes. Other variables were also looked into and it was concluded that teachers and learners as well, can rely on this sub-categorization approach as a reliable paradigm for their assumptions concerning word classes.展开更多

However, anaphora alone cannot contribute to ironic effect, and only by resorting to other resources like contextual information, can anaphora generate irony. Therefore, Yus＇ s classification of contextual sources is employed to analyze with examples how anaphora creates irony by the aid of context. Ultimately, the conclusion has been drawn that anaphora is able to produce irony with the help of six groups of contextual information classified by Yus except the category--speaker＇s nonverbal behavior and anapbora sometimes has to interact with several groups of contextual information in order to create irony.展开更多

In this respect, address forms are socially driven phenomena which make the fundamental point in sociolinguistics clearly. The attempt of this study will be made to discuss the impact of the cultures, especially people in America and China. Mainly, the paper is pertinent to ask some questions： （1） whether there are any different pronouns of address used in different cultures, （2） the discrepancy of forms of address used in America and China and how interlocutors used them respectively and （3） are there any semantic systems presented in both two cultures based upon interlocutors＇ social position and cultural background.展开更多

Many of these challenges arise because the context of a transaction-related crosscutting concern consists of loosely-coupled abstractions like dynamically-generated identifiers, timestamps, and tentative value sets of distributed resources. Current aspect-oriented programming languages do not provide joinpoints and pointcuts for weaving advice into high-level abstractions or contexts, like transaction contexts. To address these problems, we propose an extension to AspectJ framework, called TransJ, that allows developers to define pointcuts in terms of transaction abstractions and that automatically keeps track of context information for transactions. This paper describes TransJ as an abstract independent framework for weaving crosscutting concerns into high-level runtime abstractions, with which developers can implement transaction-related crosscutting concerns in modular, cohesive and loosely coupled transaction-aware aspects. Finally, this paper presents eight different ways in which TransJ can improve the reuse with preserving the performance of applications requiring transactions. Informally, these hypotheses are that TransJ yields （1） better encapsulation and separation of concern; （2） looser coupling and less scattering; （3） higher cohesion and less tangling; （4） reduces complexity; （5） improves obliviousness; （6） preserves efficiency; （7） improves extensibility; and （8） hastens the productivity. A brief discussion of experiment to test the hypotheses is provided, but the details of the experiment are left for another paper.展开更多
