Multilingual linguistic resources are usually constructed from parallel corpora, but since these corpora are available only for selected text domains and language pairs, the potential of other resources is being explored as well. This article seeks to explore and to exploit the idea of using multilingual web-based encyclopedias such as Wikipedia as comparable corpora for bilingual terminology extraction...
Business strategy is aimed to support the vision of an enterprise, by paving the way to achieve it through goals that direct the strategy's execution. However, there is a lack of means to establish and assess the alignment of business strategy and goal oriented requirements engineering. The objective of our ongoing research is to model business strategy in order to establish well-defined and traceable...
Collaborative Business Processes (CBP) are more and more prevalent to be used to describe collaboration requirements among enterprises; at the same time humans and service-based applications are closely related with collaborative business processes. To solve the above two problems, BPMN is proposed and promoted by many IT vendors. This paper compares six CBP tools based on BPMN. The comparison is...
The impact of information technology on business operations is widely recognized and its role in the emergence of new business models is well-known. In order to leverage the benefits of IT-supported business processes the security of the underlying information systems must be managed. Various socalled best-practice models and information security standards have positioned themselves as generic solutions...
Text information processing depends critically on the proper representation of documents. Traditional models, like the vector space model, have significant limitations because they do not consider semantic relations amongst terms. Global Association Distance Model (GADM) is an alternative that includes this consideration for document representation, assuming basically that two documents should be...
Software engineering-the art of building software-has become a crucial skill in a global economy increasingly affected by IT. This paper tries to indicate where a specific advanced software engineering activity takes place, and how different countries compare. We propose a proxy metric for the activity, and analyze the corresponding data set by location and economic performance. Main findings: Europe...
Access controls is an important IT security issue and has accordingly been a huge research topic for the last decade. Many models and role engineering methods have been provided since then, and RBAC has appeared to be one of the most significant contributions. In parallel to those developments, new requirements have appeared in the field of IT governance and they provide new constraints for the elicitation...
This paper advocates an approach to requirements analysis drawing on social scientific research strategies (Ethnography) and model based engineering (MBE). Our work is aimed at bridging the gap between applied ethnographic reports and the early stages of the software development lifecycle (SDLC). Taking a view on how we think data should be represented at the requirements level, we demonstrate an...
Several reports indicate that the highest business priorities include: business improvement, security, and IT management. The importance of security and risk management is gaining that even government statements in some cases have imposed the inclusion of security and risk management within business management. Risk assessment has become an essential mechanism for business security analysts, since...
Model Driven Architecture (MDA) has gained attention from human-computer interface community because of its capability of code generation from abstract models and transformations. MDA approaches and tools in this context include, usually, the personalization of interface design elements (such as I/O fields, screen resolution, screen size, and so on) based on some information about the context of use...
This paper explores the curious domination of the data-information-knowledge hierarchical model in the knowledge management context. Knowledge management is about a cluster of activities that take place in organizations aimed at better decision-making and organizational processes. Why would a model of key terms derived from information theory be dominant in an organizationally defined activity? We...
Aspect-Oriented Software Development (AOSD) concentrates on determination and modularization of orthogonal concerns that cut across system modules. An aspect-oriented extension framework helps transform existing methodologies into processes which support AOSD. The authors propose a framework for extending agile methodologies with AOSD features. The stages required for constructing the framework have...
In this article we propose to use the conflict in the context of the belief functions theory in order to assess the quality (called here the relevance) of an information source. We study two measures of conflict proposed in two similar approaches that aim to assess this quality of an information source. Empirical tests show that both measures give globally close results and that the notion of relevance...
Context-Aware Software Systems adapt their response to the execution context. Therefore, context information processing is fundamental, since it determines the behavior of the application. Thus, a mechanism for the collection, representation and validation of context information should be provided. In this paper, an extension of Loucopoulos' requirements engineering process incorporating context information...
Since its beginnings in the late 1960s, the IT services industry has signed long-term (10 to 20 year) contracts to maintain software and operate a system for a fixed decreasing price. The motivation for this paper stems from forty years of watching software maintenance artifacts and operations artifacts continue to diverge down two separate paths filled with duplication and unused information. Occasionally,...
Non-Functional Requirements (NFRs) elicitation is a critical stage in software development. Currently there are incipient advances aimed to the NFRs systematic elicitation. This article presents a proposal for the NFRs elicitation from business process models existing in organizations. The main contribution of the approach is to assist the requirements engineer in the systematic NFRs elicitation process...
A collaborative information system is an Inter-Organizational Information System (IOIS) that can work beyond the typical borders of organizations. When partners want to work together, they already know the goal of the project through collaborative information system. Therefore, a collaborative network allows a goal to be met that cannot be completed by one partner. Due to the complexity of this type...
Continuous changes and extensions of enterprise information systems (IS) are the main causes of their fragmentation and redundancy. The notion of service and service-oriented engineering emerges as a prospective approach to deal with IS evolution. The shift form IS to information services systems (ISS) requires to re-think the fundamentals of IS development methods and to re-align them with the brave...
