Title:

"Data Analytics in the Cloud: A Oasis or just a Mirage?"

ABSTRACT.

Cloud computing has emerged as a new paradigm for scalable,fault-tolerant, elastic, and self-manageable computing over large data-centers. In the commercial arena, large Internet and Web service and application providers have demonstrated the effectiveness of cloud computing to analyze and process petabytes of Web data. As other entities migrate their respective Information Technology infrastructures to the cloud, a natural question arises if the relatively simple model of distributed and parallel data processing and analysis based on the MapReduce paradigm will be able to cope with
the complex analysis that is warranted in the context of data warehousing, business intelligence, and scientific data analysis.
With this backdrop, we start by motivating the accelerating need for scalable analytics over vast amounts of data of different types for diverse applications in variety of domains. We then review the state-of-the-art of data analytics in the cloud and summarize the current state of a heated debate that has emerged where it is being argued that MapReduce is a step in the wrong direction for data analytics. We then provide our perspective on this debate and
stipulate some of the enhancements that can be made to the MapReduce paradigm to enable online analytical processing over massive amounts of data in the cloud. We conclude this talk with some remarks about the future trends in the context of data analytics as well as the future vision of an integrated data management and data analytics architecture in the cloud settings.

Title:
"Trust, risk and usage control"

We present a framework for usage control in GRID services. Usage control is suitable for managing continuously the usage of GRID resources, depending on several factors. Our prototype allows both coarse grain control at service level as well as fine grain control on local resources. Usage control naturally is interrelated to the notions of risk and trust. We show how these notions can be naturally embedded in the usage control framework for GRID services.

Title:
"Web 2.0 Creates a New Government"

Competition is growing among countries, companies and institutions. Feeling the pressure from competition innovation is regarded as panacea. Also for Government innovation has become essential. It gives the State the ability for coping with societal needs posed in economics, welfare, health, education, environment etc. Thus, Government has to be open for innovating Government and citizens play a growing role in such innovation processes. Now, with Web 2.0 the adequate tools and methods for that role have become available.

So, under such names as Web 2.0 and social media, a new wave of web-based applications has emerged. These applications rely on the concept of the user as a producer and provide a way to improve Public Governance. With a social web new ideas are diffusing much more rapidly. An early recognition of the new role of the user came from Time Magazine (25 Dec 2006). In that issue it made “The User the Person of the Year”. Therefore the front-page of that edition had a reflecting foil mirroring the spectator.

Web 2.0 is a great means to favour involvement of staff and citizens to create a better Government. Regarding the side of Public Administrations, social media enable to get response. Citizens may suggest improvement so providing feedback to agencies and makes administration more accessible. Within agencies staff persons use the Web 2.0 for cross-agency collaboration, good practice exchange and knowledge management. Another field is lawmaking – an effort involving politicians, administrations, citizens and experts. Connecting stakeholders will make law-making more effectively. Empowered through ICT law making may become more transparent, accessible and accountable.

Concerning the citizens’ side, social media are great to improve all kind of civic society activities. The perceived democratic deficit requires new relationships between state and citizens. Public responsiveness should be improved, one wants to reconnect citizens with politics and policy making. Also knowledge and expertise of citizens should be tapped in a well. Concrete applications are manifold including the following ones: political participation, advising of other citizens, assisting monitoring and law enforcement, providing service ratings. Several projects aim at involving citizens in urban planning. This may target even quite detailed questions such as allocating budgets for recreation facilities etc.

Title:
"Understanding the Human Genome: A Conceptual Modeling-Based Approach"

ABSTRACT
The genotype-phenotype linkage is one of the main challenges that modern Bioinformatics faces. Understanding how this linkage is accomplished would allow to answer fascinating questions as where do we -human beings- come from, and why do we behave as we do. Genes in the DNA, code for proteins whose structure accounts for function and produces the final phenotype, the role of the environment... They all conform an extremely interesting domain, that could be modeled from an Information System perspective. This set of questions are looking for more and more precise answers, that could be provided if the well-known, sound concepts of conceptual modeling were properly applied. That Information Systems perspective can provide new insights to this problem, through the specification of precise Conceptual Schemas that could be seen as the model at the Problem Space, whose representation at the Solution Space is just the Human Genome, the final objective being interpreting and understanding the semantics that are behind how the Human Genome works. The keynote will address these ideas, and will analyze how a Conceptual Schema can be constructed, to characterize and armonize the tons of data that are currently available, too often with redundancies, inconsistencies and other data quality problems that prevent them from being properly exploited.

Title:
"Web Advertising"

We will outline the science and the technology behind web advertising. We will first review the various forms of web advertising served up by advertising networks such as Google, MSN and Yahoo!. We will then introduce the technical challenges and solutions for such problems as: given a users search query, how do we determine which advertisement(s) to present? Of all the advertisers who wish to present their ads on a particular query, who should succeed? The
solutions to these problems span fields from text mining and retrieval, to the theory of auctions and marketplaces. We conclude by discussing some of the ethical, legal and privacy challenges around the responsible use of data for web advertising.

Title:
"Negotiation Technology"

ABSTRACT:

Traditional negotiation, conducted face-to-face and via mail or telephone, is often difficult to manage, prone to misunderstanding, and time consuming. Automated negotiation promises a higher level of process efficiency, and more importantly, a faster emergence and a higher quality of agreements. The potential monetary impact has led to an increasing demand for systems composed of software agents representing individuals or organizations and capable of reaching efficient agreements (e.g., the business trend toward virtual enterprises, or the pivotal role that electronic commerce is increasingly assuming in many organizations).

In this talk, we will outline the science and technology behind automated negotiation. Firstly, we will introduce a generic framework for automated negotiation. Next, we will assess the sophistication of the majority of work in the literature according to the different components of the framework. We then describe some important automated negotiation systems. Finally, we will highlight some of the major challenges for future automated negotiation research.

SHORT BIO:
Fernando Lopes received the M.Sc. degree in Computer Science and the Ph.D. degree in Artificial Intelligence from the Technical University of Lisbon (IST), Lisbon,Portugal. He was a Postdoctoral Researcher in the Department of Computer Science at the University of Liverpool, UK, where he carried out basic research in agent-based computing, notably agent-mediated negotiation.

Currently, Fernando Lopes is a researcher at the National Research Institute (LNEG),Lisbon, Portugal. His research interests include negotiation in multi-agent systems, software engineering aspects of autonomous agents, and applications of agent-based computer systems. The research work is interdisciplinary in nature and involves methods and techniques from artificial intelligence, game-theory, and some fields of the social sciences (e.g., international relations and social psychology).

Fernando Lopes has published over thirty refereed articles in journals and conference proceedings. He is an editorial board member of the International Journal of Artificial Intelligence (CESER Publications) and a programme committee member of the International Conference of the British Computer Society's Specialist Group on Artificial Intelligence.

Tommaso di Noia and Azzurra Ragone, Politechnic of Bari, Italy

Title:

"Electronic Markets, a look behind the curtains: how can semantic matchmaking and negotiation boost e-commerce?"

We will present different semantic-based approaches to matchmaking and negotiation in electronic markets, showing how semantics can lead to a new generation of Electronic Commerce systems.
We will review different solutions to solve the two problems in the context of search/retrieval, multiattribute auctions, advertising, just to cite a few, showing the added-value provided by these techniques in so lively environments.
The presentation will range from strictly semantic-based approaches, to those combining logic languages with utility theory, to most recent ones relying on Semantic Web technologies.
We will finally show some prototypes that allow users to interact with these systems through a very simple and intuitive user-friendly interface, hiding the underlying technicalities.
