A Review of the European Union eParticipation Action Pilot Projects
Abstract: Purpose – As the society has long ago left the “industrial ...more
age” and entered the “information age”, people, enterprises and above all decision makers are constantly trying to get the best out of the opportunities and the technologies offered, for facilitating their life and their work. One of the most active and promising domains nowadays, is eParticipation, which is actively promoted by all stakeholders, as there is a great need of reconnecting citizens with the decision makers and re-engaging them into the democratic procedures, especially as during the last years this gap is expanding, with the most convincing proof being the huge figure of voter turnout during the latest European elections. The purpose of this paper is to address these issues. Design/methodology/approach – A review of the most active and well-known eParticipation action pilot projects funded in the European Union is presented, alongside with a methodological framework that has been followed for mapping, assessing and evaluating those projects, using a beyond the state-of-the-art classification method. Findings – Conclusions of the performed work are in a position to outline the current status quo of eParticipation in Europe, highlighting lessons learned and opportunities for future activities and research. Originality/value – This paper includes valuable information towards practitioners, decision makers and administration officials, based not only on the established knowledge and on the experiences gained, but also on the identified gaps of the domain, aiming to support them in understanding the status quo of the domain and in the design process of future research roadmaps for eGovernace and policy modelling.

Implementation and Evaluation of eParticipation Systems in Western Balkan National News Agencies: The user perspective
Abstract: eParticipation is a developing field in which various ...more
implementation and evaluation methods may be used, according to each specific project’s content and context. The evaluated aspects of an eParticipation project should focus on both the technological acceptance by the users and its contribution towards participative decision making and deliberation. In this context, we present a prototype eParticipation system, as it was implemented in the National News Agencies of Albania, Fyrom and Serbia. The novelty of this electronic participation system, that allows citizens to comment and discuss the news items as they appear in the News Agencies’ web sites, inspires focusing on user reaction and investigating the suitability of the proposed eParticipation model in practice. Focusing on the user perspective, the paper presents how the Technology Acceptance Model was used to evaluate this system that spans in multiple countries, languages and cultures. The evaluation results pinpoint several technical and societal challenges that relate to the implementation of eParticipation systems in developing countries.

Transforming Traditional Production System Transactions to Interoperable eBusiness-aware Systems with the use of Generic Process Models
Abstract: Through the years, successful enterprises have been ...more
identified as the ones that were able to adapt their processes and ways of conducting business to the needs of their environment and the technological achievements of their times. This statement has not changed during recent years, but today, due to the major breakthrough of the internet and the possibilities it offers for a unified electronic marketplace, enterprises have to take advantage of the new technological tools offered, in order not only to adapt to this new emerging environment, but also to benefit from it and expand their operations in parallel with minimising costs. Achieving interoperability of the various production systems, and not only enabling hard-wired connectivity, seems to be the key that will unlock the gates leading to this newly established global market, and therefore enterprises need to focus more on their already established processes in order to be able to formulate a global standard for executing business transactions and cooperating smoothly with each other.

Implementing Federated Interoperability Infrastructures: Issues and Challenges from the Citizens Base Registry in Greece
Abstract: As the need for interoperability infrastructures and ...more
services is more and more stressed by researchers and practitioners in e-Government, Base Registries, as fully electronic, centralized repositories of information for classes of entities, pose as an infrastructure that can support aggregate electronic services delivery. In the presented approach, a Base Registry storing the citizen records is designed to integrate the legacy databases of 1,034 municipalities and is opened up to support the provision of electronic services towards governmental organizations. Discussion on the results is targeting at best practice examples that can be drawn at scientific and organizational level, but also at the key difficulties that have to be tackled in such public sector information reuse approaches – in relevance with the administrations and industry readiness in each country, in order to fulfill one of the principal conditions for pan-European Public Services.

Building eGovernment Service Portals for Local Administrations: A Cookbook Approach
Abstract: The development and deployment of e-government service ...more
portals combines two of the most active, promising and upcoming research fields; providing governmental services to citizens with the use of modern technologies and achieving interoperability which will result in the seamless cooperation of existing heterogeneous systems. The final outcome of such attempts should be fully functional and expandable information systems undertaking the task of offering governmental services to the wider public. Those systems should be user-friendly to both the end users (the citizens and the business) and public servants and should be regarded as virtual holistic systems, where ‘black boxes’ take care of the whole process of implementation and the interconnection with various existing systems being used by public administrations. This paper, presents a complete methodological approach for deploying and operating such systems, as piloted in two Greek municipalities with over 50,000 citizens and 3,000 businesses in each.

Promoting Electronic Participation Systems in the Balkans: The case of National Press Agencies
Abstract: While eParticipation systems are being deployed in ...more
many European member states, their operation in converging regions is still a problem. Socio-economic conditions, familiarisation with new democratic processes and low penetration of information technology still pose barriers for these eParticipation applications and their successful deployment calls for joint participation and cooperation of citizens and organisational bodies in order to form a unified framework consisting of guidelines and common codes of ethics. This paper presents a case study of the establishment of an eParticipation platform based on the cooperation of national news agencies in the converging regions of the Balkans.

Realising the Perspective Inter-Domain Interoperability: The Practical Power of Hybrid Architectural Approaches in Integrating Processes, Data and Services Between Businesses and Administrations
Abstract: Escalating economic and societal demands of today, ...more
along with the continuous advancements in ICT, push enterprises and administrations to move towards networked paradigms and leverage electronic transactions in their everyday practices. Although technical solutions providing the necessary interoperability means to enable such practices have been rigorously provided during the last years, their adoption and application by the foregoing stakeholders still remains limited. Several qualities of the existing solutions in technical and business level concerning the way the manage workflows, data mappings, business and legal rules along with the use of proprietary technologies and their inability to be readily set up and deployed, act as the main inhibitors for any potential users. The present work discusses the characteristics of the predominant centralized and decentralized architectural patterns for eTransactions, identifies the weak points of every case and proposes a hybrid architectural approach that brings together the "best of breed" of both paradigms. Additionally, specific insights, methodologies and underlying technologies are proposed with an objective to support the effective implementation of the proposed architecture and its basic components.

Designing Generic Municipal Services Process Models towards eGovernment Interoperability Infrastructures
Abstract: Public Administration desks are in any country the ...more
most active point of transactions between the state governments and the citizens. This fact emphasises the importance of services offered by Public Administrations and in the modern technological era, it is essential for Information Technology to provide solutions for transforming these traditionally offered services into electronic transactions that could be initiated over the Internet, aiming at the facilitation of the citizen's life, who is the eventual "client" of any government.. Although public administrations have strived over the last few years to meet this goal, their individual attempts resulted in isolated, ad-hoc systems, offering a small piece of the whole service bouquet. As the connectivity generated by the Internet is opening new opportunities in service delivery, public administrations are seeking ways to deliver integrated value-adding services though an Interoperable environment. The goal of a systematic service composition, which will guarantee eGovernment Interoperability, can be accomplished with an effective method of modeling the public services, in order to expose their interfaces and their actual workflow. Applying this method in Greek Municipalities by respecting the context of the emerging Greek eGovernment Interoperability Services Framework, various services have been analyzed, leading to corresponding generic process patterns.
