A common practice in software architecture design is to apply architectural views to design software architecture for the various stakeholder concerns. Architectural views are usually developed based on architectural viewpoints which define the conventions for constructing, interpreting and analyzing views. So far most architectural viewpoints seem to have been primarily used either to support ...

The surge of opinionated on-line texts provides a wealth of information that can be exploited to analyze users’ viewpoints and opinions on various topics. This article presents VODUM, an unsupervised Topic Model designed to jointly discover viewpoints, topics, and opinions in text. We hypothesize that partitioning topical words and viewpointspecific opinion words using part-of-speech helps to d...

This paper presents a two-stage approach to summarizing multiple contrastive viewpoints in opinionated text. In the first stage, we use an unsupervised probabilistic approach to model and extract multiple viewpoints in text. We experiment with a variety of lexical and syntactic features, yielding significant performance gains over bag-of-words feature sets. In the second stage, we introduce Com...

For reverse-engineering software architectures, architectural viewpoints need to be defined in a way where all customer needs are considered. This paper presents a systematic, scenario-based approach for identifying customer-specific viewpoints. The approach was successfully applied in the Cobus II project to identify 11 customer-specific viewpoints for describing the architecture of a COBOL sy...

Proposed object-oriented approaches are still in an initial stage of investigation and are mainly limited to modelling CAD applications which manipulate ill-deened, evolving and multifaceted objects. In this paper , we argue in favour of a model, called CEDAR, which aims at easing the modelling process by endowing object-oriented approach with a viewpoint notion. keywords: object-oriented datab...
