Abstract	Innovative Services for a Smarter Planet Many countries are rapidly moving towards a services-based economy. In keeping with this transformation, the area that has been broadly categorized as Information Technology Services has evolved immensely over the last 20 years. Today, it encompasses not only services that we typically associate with basic computing technology, such as information processing infrastructure and user applications, but also societal, governmental and industrial applications that are we call Services for a Smarter Planet. Rapid advances in technology, in particular in computer architecture and software that enables the processing of vast amounts of structured and unstructured data, have propelled this rapid evolution in novel Services. The speaker will address several aspects of this transformation in the services industry, with emphasis on the design and delivery of services in the societal and governmental domains, such as next-generation healthcare, services for smarter governments and smarter cities.

Abstract 1	The Internet: Past, Present, and Future The Internet grew rapidly from its beginnings as a research project funded by the US government agency ARPA to its current state as a pervasive technology that affects the lives of billions of people throughout the world. Throughout its phenomenal growth, the Internet has undergone significant change both in terms of its underlying technologies and in terms of its applications. New applications arose as researchers and later entrepreneurs sought to deliver new services that found demand among large segments of society. These applications, enabled by advances in computing, digital storage and signal processing, in turn necessitated technological innovation in the Internet infrastructure and operation. The Internet continues to evolve today as it encounters new demands and challenges. This talk will give an overview of mileposts in the Internet's development and will conclude with a discussion of some opportunities and directions for the future.
Abstract 2	Living in the WAM Continuum: Unified Design and Operation of Wireless and Mobile Networks Until recently, the vast majority of research in wireless and mobile focused on so-called Mobile Ad Hoc Networks (MANETs), where relatively stable end-to-end paths are the norm. More recently, research has focused on a different, Intermittently Connected Network (ICN) paradigm, where stable end-to-end paths are the exception and intermediate nodes may store data while waiting for transfer opportunities towards the destination. Protocols developed for MANETs generally do not work in ICNs since the connectivity assumptions are so different. In this talk I will first give an overview of ICNs and the types of challenges involved in their design and operation. I will then discuss our work in the WAM (wireless and mobile) Continuum project which is based on the simple but powerful observation that MANETs and ICNs fit into a continuum that generalizes these two previously distinct categories. Building on this observation, our work develops a framework that goes further to scope the entire space of wireless and mobile networks. I will summarize two efforts: The first gives clues of the fundamental relationship between ICNs and MANETs by unifying the use of message ferrying in ICNs with the well-known use of connected dominating set-based routing in MANETs. The second effort aims at developing a formal WAM Continuum framework where a network can be characterized by its position in this continuum. Certain network equivalence classes can be defined over subsets of this WAM continuum and this classification can be used to inform network design and operation. I will demonstrate how the unified view enabled by our framework can be used as a systematic, formal descriptive and evaluative tool.

AAbstract

Service Computing: Engineering the Service Science

Service computing is the next major evolution of computing that aims at transforming data into artefacts that are acted upon, ie, services. Service computing is increasingly being recognized as part of a broader agenda in Service Science, which aims at supporting the service sector with scientific underpinnings. In that respect, service computing may be viewed as the “engineering” side of service science. Service computing broadly focuses at providing a foundational framework to support a service-centric view of designing, developing, and exposing IT systems, whether it is in the enterprise or on the Web. In that respect, the Web is and will undoubtedly be the preferred delivery platform of service-based solutions. More specifically, Web services are currently without contest the key enabler for deploying service- centric solutions. Fully delivering on the potential of next-generation Web services requires building a foundation that would provide a sound design for efficiently developing, deploying, publishing, discovering, composing, trusting, and optimizing access to Web services in an open, competitive, untrustworthy, and highly dynamic environment. The Web service foundation is the key catalyst for the development of a uniform framework called Web Service Management System (WSMS). In this novel framework, Web services are treated as first-class objects. In this talk, I will first motivate the need for a uniform service management for the service ecosystem. I will then overview the core components of a typical WSMS. I will then describe our experience developing and applying a holistic service management framework in the context of an e-government application which focuses on the delivery of social services./font>

Abstract

Computational epidemiology: a new paradigm in the fight against infectious diseases
Dr. Recent years have witnessed a tremendous progress in the field of modeling infectious diseases, with a dramatic shift from abstract models to increasingly realistic approaches that rely on detailed data on human dynamics and intense computation. These sophisticate computational approaches can be used as in silico laboratories where to simulate epidemic scenarios, predict the impact of a disease on the population, and test a variety of intervention strategies. Next to the tremendous advances in modern medicine and health sciences, the recent computational progress and data revolution led to the emergence of a new discipline - computational epidemiology - that represents an additional weapon in our fight against infectious diseases, helping shedding light on several aspects of the virus propagation. The talk will address the central role of epidemic large-scale computational approaches for the study of infectious diseases spread, and will present the application to the 2009 H1N1 pandemic, aimed at helping and supporting the decision process at the scientific, medical, and public health level.

Abstract

From Crowdsourcing to Crowdservicing
Crowdsourcing as a concept as well as a practice refers to the idea that the World Wide Web (WWW) can facilitate the aggregation and/or selection of useful information from a potentially large number of people connected to the internet. It has evolved rapidly to the point it has become a short-hand for a diverse range of activities over the internet. These include prediction markets, distributed problem solving over the internet, open innovation, mass collaboration, cheap and efficient human computation and problem solving using Mechanical Turk, among others. The aspects that seem to be common across these are (a) the assignment of a problem or the distribution of some work to a large number of independent (volunteer or paid) individuals or groups through the internet, (b) some mechanism to aggregate or select from the submissions, (c) optional offer of rewards or payment. This is seen as a more robust alternative to the use of in-house teams of experts or a chosen group of contributors for a wide array of problems. The basic assumption is that the crowd can bring interesting, non-trivial, and non-overlapping information, insights, or skills, which, when harnessed through appropriate aggregation and selection mechanisms, can add to the quality of the solutions.
I will propose a taxonomy of crowdsourcing applications. My focus will be on the developments in one of the more important categories that I refer to as ‘crowdservicing’, which builds on the evolving foundation provided by web 3.0 or the service web. Some of the exciting research in this area at several of the leading research labs as well as the Knowledge Discovery and Management Research Group (KDMRG) that I direct at the University of Sydney will be discussed.
