Title: Web Advertising
We will outline the science and the technology behind web advertising. We 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.
Ricardo Baeza-Yates is VP of Yahoo! Research for Europe, Middle East and Latin America, leading the labs at Barcelona, Spain and Santiago, Chile. Until 2005 he was the director of the Center for Web Research at the Department of Computer Science of the Engineering School of the University of Chile; and ICREA Professor at the Dept. of ICT of Univ. Pompeu Fabra in Barcelona, Catalonia, Spain. He is co-author of the book Modern Information Retrieval, published in 1999 by Addison-Wesley, as well as co-author of the 2nd edition of the Handbook of Algorithms and Data Structures, Addison-Wesley, 1991; and co-editor of Information Retrieval: Algorithms and Data Structures, Prentice-Hall, 1992, among more than 150 other publications. He has received the Organization of American States award for young researchers in exact sciences (1993) and with two Brazilian colleagues obtained the COMPAQ prize for the best CS Brazilian research article (1997). In 2003 he was the first computer scientist to be elected to the Chilean Academy of Sciences. During 2007 he was awarded the Graham Medal for innovation in computing, given by the University of Waterloo to distinguished ex-alumni. In 2009 he was awarded the Latin American distinction for contributions to CS in the region and was promoted to ACM Fellow.

Title: Electronic Markets, a look behind the curtains: how can semantic matchmaking and negotiation boost e-commerce?
In this talk we will present different semantic-based approaches to matchmaking and negotiation in electronic markets, showing how semantics can lead to a new generation of EC 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.
Tommaso Di Noia is an assistant professor at Polytechnic of Bari. He received his Ph.D. in Information Engineering from Polytechnic of Bari in 2006. His main research interests include knowledge representation and its application to resource retrieval and matchmaking scenarios, description logics, pervasive computing and ubiquitous web, automated negotiation, competence management and semantic web. He co-authored three papers that received the best paper award at ACM ICEC 2004, IEEE CEC-EEE 2006 and ACM ICEC 2007.
Azzurra Ragone is a post-doc researcher at Polytechnic of Bari. She got a Ph.D. in Information Engineering from Polytechnic of Bari. Her competences cover different related fields, from Knowledge Representation to Internet Economy, from Semantic Web languages to Decision Making. Her research interests are in the area of automated knowledge-based matchmaking and negotiation, preference representation and elicitation. During her Ph.D. she spent a period of seven months at the University of Michigan in Ann Arbor, under the supervision of Prof. M. Wellman. During this period they worked together on preference representation in electronic commerce. After her Ph.D. she start to work at University of Trento on scientific research evaluation techniques and new publishing models. She co-authored over 40 papers in international journals and conferences on her research topics. She coauthored the paper "Concept Covering for Automated Building Blocks Selection based on Business Processes Semantics", which received the Best Paper award at the 8th IEEE Conference on E-Commerce Technology (CEC' 06).

Title: Negotiation Technology
Traditional negotiation, conducted face-to-face and via mail or telephone, is often difficult to manage, prone to misunderstanding, and time consuming. Automated negotiation romises 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 emand 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.
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.
He also acts as a reviewer for the European Journal of Operational Research (Elsevier Science).
