A Semantics-Based Aspect Language for Interactions with the Arbitrary Events Symbol
نویسندگان
چکیده
In this paper we introduce an aspect language that can define crosscutting e ects on a set of UML 2.0 sequence diagrams. The aspects and sequence diagrams are woven at the model level. By basing the weaving upon a formal trace model for sequence diagrams, we ensure that the weaving is semantics-based. We propose the arbitrary events symbol as a wildcard mechanism to express zero or more events on a sequence diagram lifeline. The approach is explained by a reallife example, and a weaving tool partially implements the approach.

Lexical Semantics and Selection of TAM in Bantu Languages: A Case of Semantic Classification of Kiswahili Verbs
The existing literature on Bantu verbal semantics demonstrated that inherent semantic content of verbs pairs directly with the selection of tense, aspect and modality formatives in Bantu languages like Chasu, Lucazi, Lusamia, and Shiyeyi. Thus, the gist of this paper is the articulation of semantic classification of verbs in Kiswahili based on the selection of TAM types. This is because the sem...
متن کاملApplication of Frame Semantics to Teaching Seeing and Hearing Vocabulary to Iranian EFL Learners
A term in one language rarely has an absolute synonymous meaning in the same language; besides, it rarely has an equivalent meaning in an L2. English synonyms of seeing and hearing are particularly grammatically and semantically different. Frame semantics is a good tool for discovering differences between synonymous words in L2 and differences between supposed L1 and L2 equivalents. Vocabulary ...

متن کاملDynamic Categorization of Semantics of Fashion Language: A Memetic Approach
Categories are not invariant. This paper attempts to explore the dynamic nature of semantic category, in particular, that of fashion language, based on the cognitive theory of Dawkins’ memetics, a new theory of cultural evolution. Semantic attributes of linguistic memes decrease or proliferate in replication and spreading, which involves a dynamic development of semantic category. More specific...
متن کاملDeclarative Semantics in Object-Oriented Software Development - A Taxonomy and Survey
One of the modern paradigms to develop an application is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles in applications. In an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. For the procedural semantics, we can write a ...
