General Chair Message

In this world of social media, smart phones, and tablets, whether Apple, Android, or Microsoft, the presence of Digital EcoSystems is ubiquitous. It is quite thrilling to see how this emerging marketplace influences the evolution of almost three-quarters of a million individual apps, which together constitute numerous digital ecosystems of interacting software.

And this is just the beginning. As these tools march through the institutions of our increasingly global society, we will see ever more complex applications consisting of interacting apps in the fields of health care, education, and politics, to name a few.

This area is quite complex and driven by advances in many computer science fields. The overall evolution of such an ecosystem is studied in such areas as network science, adaptive systems, and game theory. Important properties to be studied include scalability, complexity, and emergence. Other areas, such as computational intelligence, knowledge management, intelligent data management, and privacy and security, among others, also play an important role.

This, the third incarnation of MEDES, held in San Francisco, California, during November 21-23, 2011, has sessions on the following topics: web-based systems and services; web-based languages management; knowledge management, sharing and discover, computational intelligence; trust, risk, privacy and access control; software ecosystems; models and services; infrastructures and architectures; social web and virtual communities; immunity-based systems; and, electronic democracy.

Researchers from 22 countries will take part in the conference, consisting of 48 presentations. We welcome you all to San Francisco, a most pleasurable venue, for 3 days of a most interesting extended conversation.

Program Chair Message

It is my great pleasure to welcome you to attend the MEDES 2011 - The 3rd  International Conference on Management of Emergent Digital EcoSystems held on November 21 - 23, 2011 in San Francisco, California.

This year, MEDES 2011 received a total of 82 papers. Every paper was assigned to at least three reviewers on the Program Committee. More than 144 Committee Members had a peer-review process for the submitted papers, which were evaluated based on scientific originality, contribution to the field, and technical quality. As a result of the review process, several papers received as many as five reviews and only 26 regular papers and 10 short papers were accepted. All accepted papers are published by ACM and indexed by the ACM Digital Library and DBLP.

The highlight of the research program includes eight sessions. Each accepted paper will receive between 20-25 minute slot for its presentation. In addition, the program includes two special sessions on Electronic Democracy (E-Democ'11) and Immunity-Based Systems (IMBS-Global '11). This year, we are fortunate to have two distinguished keynote speakers, Dr. Paul Hofmann, Vice President Research at SAP Labs and Dr. Paul Maglio, Senior Manager at IBM Almaden Research Center, to respectively share their perspectives on the state of Information Technologies and Complex Service Systems.

I am immensely grateful to the program committee members for their kind participation and generous feedback. Committee members were a pleasure to work with thanks to their devotion and focus. I am also grateful to the many external reviewers who assisted the committee members. I am also thankful to Dr. Nashwa El-Bendary and Dr. Aboul Ella Hassanien for their effort in organizing the E-Democ'11 special session and Dr. Yoshiteru Ishida who worked tirelessly to organize the IMBS-Global '11 Special Session. I am most grateful to the General Chair, Dr. William I. Grosky, the Advisory Board Members, the Steering Committee Members, and other planning committee members of the conference for their constant support. Last but not least, I warmly acknowledge the generous support of ACM, ACM SIGAPP and IFIP.

After all, it is the authors above all that make a conference successful. For those authors whose papers did not make it, we sincerely hope that the detailed technical review comments we provided proved helpful.

I hope that all attendees leaved inspired by their experience at MEDES 2011. Wish you all a productive and enjoyable conference!
