Harnessing the crowd to collect and/or analyze massive amounts of data (crowdsourcing) has become increasingly popular. Examples in our culture include Wikipedia, social tagging systems for images, traffic information aggregators like Waze, citizen science applications such as Galaxy Zoo, and hotel and movie ratings like TripAdvisor and IMDb. Cloud platforms are also increasingly being explored for hosting crowdsourcing systems, and for exposing the crowd as a service. In this talk, I give an overview of the challenges inherent in providing declarative, database-style platforms for supporting crowdsourcing. I then discuss how to go one step further and enable users to posed general questions to mine the crowd and to receive concise, relevant answers that represent frequent significant data patterns. Finally, I discuss the importance of capturing provenance for crowdsourcing applications, and the inherent challenges due to the massive size of data and complex analytics.

Conference on Data Mining (ICDM) in 2003, the ICDM 2013 10-year Highest-Impact Paper Award, and the EDBT Test of Time Award (2014). Dr. Yu received his PhD from Stanford University.
Professor Michael Goul is Professor and Chair of the Department of Information Systems, W.P. Carey School of Business, Arizona State University. His research bridges services computing and analytics. He was Co-PI on grants from Intel and American Express at the intersection of these areas, and he recently authored a case on eBay’s approach to experimentation that relies on a multi-tenant, self-service data warehouse infrastructure. His work in services computing led to a one-year appointment as a Distinguished University Scholar at the Clinton School of Public Service. Goul is also on the research faculty of the W.P. Carey School’s Center for Services Leadership.
Despite sustained research effort in security, current security practice conveys a decidedly ad hoc flavor --- find a bug; patch it; find the next bug; and so on. This methodology is sometimes termed "engineering", using the term in the narrow sense of developing solutions to specific problems. The past few years have seen a growing push to develop a Science of Security (SoS), viewed as a systematic body of knowledge with strong theoretical and empirical underpinnings that inform the engineering of secure information systems.
I introduce SoS, briefly describing its key elements. I then motivate some of the foundational challenges of SoS from the standpoint of systems of autonomous participants, such as cross-organizational service systems. I describe how security is an element of the governance of such systems. I introduce an approach for governance based on a new formulation of norms and accountability, showing how it addresses the challenges of security pertaining to secure collaboration and would facilitate the development of flexible and secure cross-organizational service engagements.

Nineteen students have received PhD degrees and 27 students MS degrees under Munindar's direction.
Modern Service industry is not only becoming a leading and pillar industry for economic development, but also an important indicator of measuring the degree of production socialization and market economic development. As a matter of course, Service Oriented Computing, as the academic foundation of Modern Service industry, attracts lots of attention in the last decade. However, the big data and the development of emerging computing paradigms such as Cloud Computing, internet-Of-Things, and Mobile internet have made Service Oriented Computing more and more complex. in this talk, we will give the concept and overview of the development trend of Modern Service industry in the world, especially the development of Modern Service industry in China. Moreover, we give the concept and the definition of complex service, which has the characteristics of ‘3C’, i.e., convergence, and complex. Further, a technique architecture for complex service computing is provided and some case studies of complex services are provided.
