A Case Studies Approach to the Analysis of Profiling and Framing 
Structures for Pervasive Information Systems

José Eduardo Fernandes (Department of Informatics and Communications, 
School of Technology and Management, Polytechnic Institute of Bragança, 
Portugal), Ricardo J. Machado (Escola de Engenharia, Centro Algoritmi, 
Universidade do Minho, Portugal) and João Á. Carvalho (Escola de 
Engenharia, Centro Algoritmi, Universidade do Minho, Portugal)

Model-Based/Driven Development (MDD) constitutes an approach to software 
design and development that potentially contributes to: concepts closer 
to domain and reduction of semantic gaps, automation and less 
sensitivity to technological changes, and the capture of expert 
knowledge and reuse. The widespread adoption of pervasive technologies 
as basis for new systems and applications lead to the need of 
effectively design pervasive information systems that properly fulfil 
the goals they were designed for. This paper presents a profiling and 
framing structure approach for the development of Pervasive Information 
Systems (PIS). This profiling and framing structure allows the 
organization of the functionality that can be assigned to computational 
devices in a system and of the corresponding development structures and 
models, being. The proposed approach enables a structural approach to 
PIS development. The paper also presents two case studies that allowed 
demonstrating the applicability of the approach.

*Web-based Technologies Integration for Distributed Manufacturing 
Scheduling in a Virtual Enterprise*

Today’s manufacturing enterprises face enormous competitive pressures 
stemming from the current dynamic and open business context. Global 
competition and market demand for customized products and services, 
delivered ‘just in time’, exert real stress on businesses. Recently, new 
production paradigms, such as the extended enterprise, as well as agile, 
virtual and networked manufacturing, have appeared in response to the 
increasingly dynamic conditions of the marketplace. These new concepts 
prompt geographically dispersed manufacturers to build alliances with 
their suppliers and customers in order to work more closely with them. 
They need to work to build manufacturing networks which bridge large 
sections of the supply chain. In this context distributed scheduling 
problems are challenging tasks to researchers and practitioners that 
have been gaining increasing popularity over the years. This is partly 
attributed to the fact that multi-site production and networked 
manufacturing environments are increasing as a consequence of 
globalization. In this paper a web based system for technologies 
integration for supporting distributed scheduling in a Virtual 
Enterprise, by combining a simulation-based approach, with the Hungarian 
algorithm, for solving job-shop scheduling problems is presented, in 
order to show how the authors can benefit from this technologies 
integration for supporting collaborative distributed manufacturing 
scheduling.

*Dataspaces Enhancing Decision Support Systems in Clouds*

Business Organizations increasingly rely on publicly accessible 
communication infrastructures such as the Internet and Cloud computing, 
in order to manage their internal processes and offer their services to 
financial actors, businesses and ordinary people worldwide. However, 
little attention has been paid to embracing Software-as-a-Service (SaaS) 
philosophy for supporting business analysts in evaluating effectiveness 
and relevance of business information or finding patterns to direct them 
on more sources of data. This paper proposes a flexible architectural 
framework for modelling application services useful in supporting 
business decision processes. This architecture goes beyond the static 
schemas offered by data warehouse systems as it supports including data 
gathered from heterogeneous sources and added-value services offered in 
Internet or provided by Cloud infrastructures. Central to this 
architecture is the concept of dataspace as a reference model for 
structuring information relevant to a particular organization, 
regardless of its format and location. A case study of a real world 
implementation is presented dealing with supporting decisions in the 
real estate domain.

*UNDERGRADUATE STUDENTS’ SATISFACTION WITH THE USE OF WEB PORTALS*

**

and Information Science, University of Ilorin, Nigeria)*

This study examined undergraduate students’ satisfaction with web 
portals and considers the benefits of using the portal and the problems 
associated with the use of portal. A pure quantitative method using 
descriptive survey approach is adopted. A questionnaire was used for 
data collection. Collected data was analysed using percentages and 
frequency count; multiple correlation and regression. The results reveal 
that students were generally satisfied with the e-portal system with, 
89.3% indicating they were adequately satisfied, satisfied, and 
moderately satisfied. On the other hand, 11.1% had little satisfaction 
with the portal. Information/content quality, system quality, and ease 
of use were indicated to determine users’ satisfaction. Furthermore, the 
entire user satisfaction dimensions positively and significantly 
correlate with and predict students’ satisfaction with the web-portal. 
The study concluded by pointing out the implications and the 
recommendations based on the findings for the improvement of the 
students’ web portal.

*Script Familiarity and Its Effect on CAPTCHA Usability: An Experiment 
with Arab Participants*

**

*Ashraf Khalil (College of Engineering and Computer Science, Abu Dhabi 
University, UAE), Salam Abdallah (College of Business Administration, 
Abu Dhabi University, UAE), Soha Ahmed (College of Engineering and 
Computer Science, Abu Dhabi University, UAE) and Hassan Hajjdiab 
(College of Engineering and Computer Science, Abu Dhabi University, UAE)*

Many web-based services such as email, search engines, and polling sites 
are being abused by spammers via computer programs known as bots. This 
problem has bred a new research area called Human Interactive Proofs 
(HIP) and a testing device called CAPTCHA, which aims to protect 
services from malevolent attacks by distinguishing bots from human 
users. In the past decade, researchers have focused on developing robust 
and safe HIP systems but have barely evaluated their usability. To begin 
to fill this gap, the authors report the results of a user study 
conducted to determine the extent that English language proficiency 
affects CAPTCHA usability for users whose native language is not 
English. The results showed a significant effect of participants’ 
English language proficiency level on the time the participant takes to 
solve CAPTCHA, which appear to be related to multiple usability issues 
including satisfaction and efficiency. Yet, they found that English 
language proficiency level does not affect the number of errors made 
while entering CAPTCHA or reCAPTCHA. The authors’ results have numerous 
implications that may inform future CAPTCHA design.

*CALL FOR PAPERS*

Mission of IJWP:

The *International Journal of Web Portals (IJWP)* focuses on enterprise 
integration strategy that deals with the exchange of messages as the 
basic component of the solution architecture enabling the integration of 
people, information, applications and business processes. Portals are 
expected to care more about the infrastructure services they consume, 
which is a key architectural difference between the past and the future 
generations of portals and represent the paradigm shift in enterprise 
integration strategy. This paradigm shift focuses on identifying core 
integration components, assets, enterprise portals and encourages the 
reuse and refinement of these assets for integration projects. However, 
these topics are rarely discussed among the practitioners or in the 
international journals without primarily encouraging use of the 
solutions from particular vendors. It is important to establish a 
sounding board (international journal) which provides readers with an 
independent view of models for enterprise integration strategies, vendor 
independent tool sets, and the experience with the development of 
strategic solutions carried out within the context and rules of the 
enterprise's integration architecture. The readers are expected to 
benefit from having access to the latest practical solutions, as well as 
research papers in the field of integration approaches, the review of 
tools which can effectively and proactively support integration 
objectives across the enterprise.

Coverage of IJWP:

Topics to be discussed in this journal include, but are not limited to, 
the following:

Business process integration and management using SOA and portals
