The architectural design of distributed enterprise applications from the viewpoints of different stakeholders has been proposed for some time, for example, as part of RM-ODP and IEEE 1471, and seems now-a-days to gain acceptance in practice. However, much work remains to be done on the relationships between different viewpoints. Failing to relate viewpoints may lead to a collection of viewpoint...

When presented with many relevant documents about a controversial topic, humans do not always read and trust them uniformly. Instead, they tend to follow and agree with articles and sources that hold similar viewpoints as theirs, a phenomenon known as confirmation bias. This suggests that when acquiring additional knowledge about a controversial topic, human biases and viewpoints about the topi...

Résumé : Avec le Web 2.0, les utilisateurs, devenus contributeurs, ont pris une place centrale dans les processus de consommation et de production de connaissances ; cependant la paternité des contributions est souvent perdue lors de l’indexation de l’information. VIEWPOINTS est un formalisme de représentation des connaissances centré sur le point de vue individuel, humain ou artificiel. Nous c...

In response to the increasingly challenging task of developing software, many companies turn to Software Process Improvement (SPI). One of many factors that SPI depends on is user (staff) involvement, which is complicated by the fact that process users may differ in viewpoints and priorities. In this paper, we present a case study in which we performed a preSPI examination of process users’ vie...

The effectiveness of rigorous specification methods such as sequence-based specification is often limited by the specification team's ability to understand the system requirements. Viewpoints and use-case methods address this issue by supporting requirements elicitation and informal description of system requirements and interfaces. However the system requirements developed using these methods ...

Ensuring that specifications are consistent is an important part of specification development and testing. In this paper we introduce the ConsVISor tool for consistency checking of RM-ODP specifications. This tool is a category theory based consistency checker for formal specifications in a variety of languages, including both graphical and non-graphical modeling languages. Because RM-ODP suppo...

This paper discusses the use and integration of formal techniques in particular Z into the Open Distributed Processing ODP standardization initiative One of the cornerstones of the ODP framework is a model of multiple viewpoints During the development process it is important to maintain the consistency of di erent viewpoints of the same ODP speci cation In addition there must be some way to com...

The integration of spatial information perceived from different viewpoints is a frequent, yet largely unexplored, cognitive ability. In two experiments, participants saw two presentations, each consisting of three targets-that is, illuminated tiles on the floor-before walking the shortest possible path across all targets. In Experiment 1, participants viewed the targets either from the same vie...

We present an empirical study aimed at analysing the use of viewpoints in an industrial Concurrent Engineering context. Our focus is on the viewpoints expressed in the argumentative process taking place in evaluation meetings. Our results show that arguments enabling a viewpoint or proposal to be defended are often characterized by the use of constraints. Firstly, we show that, even if some con...

Threaded discussion forums provide an important social media platform. Its rich user generated content has served as an important source of public feedback. To automatically discover the viewpoints or stances on hot issues from forum threads is an important and useful task. In this paper, we propose a novel latent variable model for viewpoint discovery from threaded forum posts. Our model is a ...
