In February 2011, Watson (IBM super computer) managed to beat two past grand champions on the TV quiz show Jeopardy!. Watson was able to answer questions that require intelligence when done by humans. This marked the first machine to pass the Turing test and started a new era of computing called cognitive computing where computers (modeled after the human brain) learn and interact naturally with people to extend what either humans or machine could do on their own. Google, Amazon, Facebook, etc., using big data technologies, smart Machine Learning and AI algorithms were able to tap into our intensions by predicting what we click, buy, like, dislike, shop, surf, etc.,. This marked the era of smart Web or predictive intelligence where Turing test is reversed and machines now try to figure out who we are, our information needs, our behavioral patterns, the activities we are engaged in and our goals. Together with the torrents of data we leave behind us every time we communicate with the digital eco-system, a new era of human-machine cooperation is starting that gives us millions of potential insights into user experience, marketing, personal tastes, and human behavior. In this talk, we are going to illustrate through motivating cases and research directions the main characteristics of this era and how it can transform the way we interact with the Web to ultimately improve the quality of our lives and gain valuable insights into our affective, mental and physical states.

The engineering of systems involves many different stakeholders, each with their own domain of expertise. Hence more and more organizations are developing an ever growing number of Domain Specific Languages (DSLs) to allow domain experts to express solutions directly in terms of relevant domain concepts. This new trend raises new challenges about designing not just one DSL but many of them, evolving a set of DSLs and coordinating the use of multiple DSLs. In this talk we explore various dimensions of these challenges, and outline a possible research roadmap for addressing them. We detail one of these challenges, which is the safe reuse of model transformations. Indeed both DSL definition and tooling (eg. checkers, document or code generators, model transformations) require significant development efforts, for a limited audience (by definition), because the current state of the art of Model Driven Engineering still makes it hard to reuse and evolve these definitions and tooling across several DSLs, even when these DSLs are conceptually very close to one other. We outline a new extension to the Kermeta language that leverages Family Polymorphism to allow model polymorphism, inheritance among DSLs, as well as evolution and interoperability of DSLs.

Resilient Optical Network Virtualization

Cloud computing services are emerging as an essential component of the industry ICT infrastructure and, consequently, one of the fastest growing business opportunities for Internet infrastructure and service providers. Many enterprises are moving their services towards cloud infrastructures. In this rapidly growing market, datacenter (DC) scalability is becoming a major technical challenge for service providers as well as its performance optimization, with a key focus on the network technologies and their control. In fact, service providers have to cope with cloud services delivered by more and more geographically distributed DCs, ever increasing requests by users and DC providers for very high throughputs and low latencies, resource dynamicity and elasticity (i.e. flexible storage and computing on demand) and seamless resource/service migration. The future Internet architecture needs to offer:
  • An efficient integration between the high-performance and high-bandwidth optical network infrastructure of operators and services/resources provided by DCs and server farms.
  • End-to-end cloud service provisioning eco-system that automatically and efficiently bundles DC infrastructure services (i.e. computing and storage) with the required operator optical network connectivity services.
  • A highly resilient virtual infrastructure as a major disadvantage of a virtual architecture is that a single hardware fault or a defect in the virtualization infrastructure (VI) software can lead to the failure of multiple virtual nodes by, for example, preventing VMs from being scheduled or preventing VMs from accessing I/O devices. Hence, a key to enabling the deployment of virtual clusters is to enhance the resiliency of the VI to faults in the hardware or virtualization software.


Brigitte  JAUMARD Brigitte JAUMARD holds a Concordia University Research Chair, Tier 1, on the Optimization of Communication Networks in the Computer Science and Software Engineering (CSE) Department at Concordia University. Her research focuses on mathematical modeling and algorithm design for large-scale optimization problems arising in communication networks, transportation networks and artificial intelligence. Recent studies include the design of the most efficient algorithms for p-cycle based protection schemes, under static and dynamic traffic, and their generalization to the so-called p-structures, which encompass all previously proposed pre-cross-connected preconfigured protection schemes. Other recent studies deal with dimensioning, provisioning and scheduling algorithms in optical grids or clouds, in broadband wireless networks and in passive optical networks. In Artificial Intelligence, contributions include the development of efficient optimization algorithms for probabilistic logic (reasoning under uncertainty) and for automated mechanical design in social networks (design of trust estimator tools). In transportation, her recent contributions include new algorithms for freight train scheduling and locomotive assignment. B. Jaumard has published over 300 papers in international journals in Operations Research and in Telecommunications.

Social Engineering has long been a very effective means of attacking information systems. The term knowledge worker has been coined by Peter Drucker more than 50 years ago and still describes very well the basic characteristics of many employees. Today, with current hypes such as BYOD (bring your own device) and public cloud services, young professionals expect to use the same technology both in their private life and while working. In global companies teams are no longer geographically co-located but staffed globally just-in-time. The decrease in personal interaction combined with the plethora of tools used (E-Mail, IM, Skype, Dropbox, Linked-In, Lync, etc.) create new opportunities for attackers. As recent attacks on companies such as the New York Times, RSA or Apple have shown, targeted spear-phishing attacks are an effective evolution of social engineering attacks. When combined with spear phishing to distribute zero-day-exploits they become a dangerous weapon, often used by advanced persistent threats. In this talk we will explore some attack vectors and possible steps to mitigate the risk.
