A Product Line Architecture (PLA) should remain stable accommodating evolutionary changes of stakeholder’s requirements. Otherwise, architectural modifications may have to be propagated to products of a product line, thereby increasing maintenance costs. Hence, it is important to understand which techniques better cope with PLA stability through evolution. This paper presents a comparative stud...

No longer can courseware providers deal with one homogeneous target group, one learning form and possibly one pedagogical approach. Instead they must develop a broad range of courseware, each serving its specific target group, each adjusted to a specific learning and teaching form, each appealing to its own learning and teaching scenario, and each incorporating its own pedagogical approach, and...

this study aims to investigate the semantic and syntactic features of verbs used in the introduction section of applied linguistics research articles published in iranian and international journals. a corpus of 20 research article introductions (10 from each journal) was used. the corpus was analysed for the syntactic features (tense, aspect and voice) and semantic meaning of verbs. the finding...

Aspect-based sentiment analysis is a fine-grained task that consists of two types subtasks: aspect term extraction and classification. In the task, current methods suffer from lack information in difficulty identifying boundaries. classification classifier cannot adapt itself to text determine local context. To address these challenges, this work proposes an adaptive semantic relative distance ...

In our previous work, we have been interested in the development of methodologies and techniques for the specification and verification of distributed multimedia systems, with particular emphasis on object and component-based systems [Blair98a]. This has led us to develop an aspect-oriented style of specification that follows the principles of aspect-oriented programming [AOP00][Murphy99]. Esse...

Aspect-oriented programming (AOP) is an emerging technique that provides a mechanism to clearly encapsulate and implement concerns that crosscut other modules. It is claimed that this technique improves code modularization and therefore reduces complexity of object-oriented programs (OOP). Most of the proposed complexity measurement frameworks for AOP are for AspectJ programming language. In th...
