Abstract
The relationship of information systems to the business has evolved over the years from that of a tool builder that enabled the business to perform their tasks more efficiently to a facilitator for introducing new differentiated products and services and even transforming the way organizations and individuals work. Inevitably there has been an increased amount of business concepts being controlled by software components rather than business experts. The distinction between business and software is not as clear as it may have been in the past. How many business rules are handled by software in a manner that is so opaque that a domain expert has to delegate the evolution of such rules to a software engineer? What kind of business opportunities, innovation, and differentiation can an information system offer the business or an entire industrial sector? On reflection, the relationship between the business and IT is neither uni-directional nor linear. The traditional model whereby business experts establish, the goals, the constraints, the functions and the quality levels that the software must meet and the developers deliver a system that meet these characteristics is nowadays often challenged as inadequate. The very essence of a software system may itself offer opportunities for change to the business objectives, constraints and functions. These feedback mechanisms need to be externalized, and evaluated during a most critical development activity, namely that of requirements engineering.

This talk will explore the strategic role of requirements in analyzing the intertwining between business and software focusing on the role of conceptual modeling and simulation in a process that represents an exploration of alternatives, continuous evolution in the design direction and validation and feedback on user requirements.

Abstract
In 1985, in an interview for some then-popular magazine, I was asked when models and model-driven development would become commonplace. "In three years time," I replied confidently. In 1987, I was asked the same question, and my answer remained the same. And 1989. And '91. Were you to ask me the same question today, I would answer it in the same way. Perhaps I should have gone surfing instead.

While my answer has the virtue of consistency, how could I--how could we?--have been so wrong? Of course, we didn't have the technology back then. And we didn't have the computer power that could allow us to ignore certain inefficiencies introduced by abstraction. But have things really changed that much in nearly a quarter of a century? Our tools and computers are certainly better, but it is clear that we have failed to convert the great unwashed to the benefits and wonders of models and model-driven engineering.

This keynote will take a personal view of why we have (let's be positive, shall we?) yet to succeed. It will explore several technical, business and marketing issues that have impeded our progress. And because a keynote is intended to be positive, leaving delegates upbeat and energized, we shall also examine some encouraging indicators that could lead to model-driven engineering soon becoming commonplace. In, oh, let's say, three years.

Brief Bio
For the last few years I have been doing research in the areas of conceptual modelling, metamodelling and development methodologies. In July 2008 I took up a position with The Heritage Lab (LaPa) at the Spanish National Research Council (CSIC) to focus on the application of information technologies to cultural heritage research and management. Prior to this I worked for eighteen months at the European Software Institute, and over four years at the Faculty of IT of the University of Technology, Sydney, from where I was a co-editor of the AS 4651 and ISO/IEC 24744 standardisation projects. I am the founder and former technical director of Neco, a company based in Spain specialising in software development support services, which include the deployment and use of OPEN/Metis at small and mid-sized organizations. I have also worked for the University of Santiago de Compostela in Spain as a researcher in information systems & archaeology, and got my PhD in this topic in 2000.


Abstract
We are often told that the development of a software system begins with the gathering of some requirements and ends when the system is deployed in the production environment where final users will employ it. Myriads of methodologies have been proposed to bridge this gap, and countless paths from requirements to deployment have been used with success. However, some specific areas of this journey remain poorly explored; this talk will focus on two of these: user interaction development and functional-to-structural modelling transition.

User interaction development refers to the modelling and refining of the structures and mechanisms that will allow human users to interact with the system. In our experience, over 35% of the effort made by a development team on a project is spent on user interface-related tasks. However, most software development methodologies and modelling languages (such as UML) blatantly neglect this area. Functional-to-structural modelling transition refers to the necessary move from a functional approach to problem description, given by user requirements and use cases, to a structural approach to solution prescription, given by the very nature of an object-oriented design. Very few methodologies give us a clear and solid explanation of how to create classes and other structural artefacts from the functional descriptions that we get from requirement analysis. In other words: "where do classes come from?"

This talk will use OPEN/Metis (www.openmetis.com) as a specific example of a methodology designed in industry with a strong academic background, and which gives (hopefully) satisfactory answers to both challenges described above.

Abstract
Some executives and pundits today think that social networks are hard to penetrate. In fact, recent news cites a decrease in corporate investment in social networks. This makes sense from the perspective that typical corporate use of social networks has focused on creating relationships and eavesdropping. The result: online ads in social networks have weak alignment to the current conversation, whose participants and content can change rapidly. One possible improvement is to use the language/action perspective: specifically, to use “conversational distance” to identify the dynamic markets that are constantly being created by different social network content and participants. To do this, the notion of “conversational distance” must take on the interpretation of “mental distance” (among two parties in a conversation) and not its more typical “physical distance” interpretation. This keynote will: explore the nature of mental distance, introduce some of its elements, show how these elements can be combined into a software-oriented architecture, and give examples of how to use that architecture to create better online ads.

Abstract
Detecting faces and facial expressions has become a common task in human-computer interaction systems. A robust face detection system must be able to detect faces irrespective of illuminations, shadows, cluttered backgrounds, facial pose, orientation and facial expressions. Many approaches for face detection have been proposed in the literature mainly dealing with the detection or recognition of faces in still conditions rather than the person’s facial expressions and the reflecting emotional behavior. In this talk, we describe a Local-Global (LG) graph based method for detecting faces and for recognizing facial expressions accurately in real world image capturing conditions both indoor and outdoor, and with a variety of illuminations (shadows, high-lights, non-white lights) and in cluttered backgrounds. We also offer a methodology for recognizing facial expressions associated to emotional behavior. This methodology uses most important facial features such as eyes, eyebrows, nose, mouth (lips) as the primitive elements of an alphabet of a simple formal language in order to synthesize facial features and generate emotional expressions. Illustrative examples are also provided for proving the concept of the methodology.
