Electronic Government and Electronic Participation: Joint Proceedings of Ongoing Research of IFIP EGOV and IFIP ePart 2013, 16-19 September 2013, Koblenz, Germany

Preface Form ore than a decade, the International Federationf or Information Processing (IFIP) Working Group8 .5 (Information Systems in Public Administration), or short, IFIP WG 8.5, has organized the EGOV (international conferenceso n Electronic GOVernment) series of conferences, whichm eanwhile has solidly established itself as a core conference in the research domain of e-government and e-governance. Since 2009, IFIP ePart, the International Conference on eParticipation, has emergedfrom the strand of EGOV as an IFIP sibling conference focusing on the domain of e-participation. IFIP EGOV is the European core conference in the domain of ICT research andpractice developments in the public sector. Each year, scholarsfromall over the globe present the state of the art andm ost recent innovations andr esearch in e-government, e-governance and related fields of study. Since its commencement in 2002, the EGOV conference has provided important guidance for research and development in this fast-moving domain of study. IFIP ePart brings together researchers of distinct disciplines to present and discuss advances in boths ocial and technological scientific domains, seeking to demonstrate new concepts,methods, and styles of eParticipation. As the field of eParticipationis multidisciplinary in nature, ePart provides an excellent opportunity for researchers and practitioners with different disciplinary backgrounds to share and discuss current research on foundations, theories, methods, tools, and innovative applications of eParticipation. ePart also provides a fruitful ground to nurture and plan future cooperation. The two conferenceshave attracted around 150 participants on average pery earfrom all continents including developing countries. Co-location of both conferences intentionally allows for exchange and cross-fertilization between the two domains of study. The Chairs of both conferences are committed to continuing the co-location. The twelfth IFIP EGOV and the fifth IFIP ePart conferencesw ere co-located with Informatik 2013, which is the GermanComputer Society's major annual conference with around 1000 participants each year. This way, German-speaking computer science and related informationg overnance scholarsw ere welcome to networkw ith e-government and eParticipation researchers and practitioners. The IFIP EGOV 2013 "Call for Papers" and the IFIP ePart 2013 "Call for Papers" attracted a wide range of topics. Thesep roceedings cover contributions of ongoing re-searchf rom both conferences, IFIP EGOV and IFIP ePart. 20 papers from EGOV and 8 papers from ePart were accepted for publication in this volume. The contributions were clustered under the following headings: All papers were double-blindpeer reviewed by at least three reviewersfrom the Program Committee with the assistance of additional reviewers.
