On behalf of the WI’09 and IAT’09 Conference Committees, we would like to thank you for your participation and we do hope that you will enjoy the conference technical and social programs. The IAT’09 and WI’09 conferences are sponsored and co-organised by the IEEE Computer Society Technical Committee on Intelligent Informatics, Web Intelligence Consortium Institute, ACM SIGART and the Department of Informatics, Systems and Communication of the Università degli Studi di Milano Bicocca, Milano, Italy. With the strong support of world-renowned researchers and practitioners from the international WI and IAT communities, the IEEE/WIC/ACM Joint Conference has received an overwhelming response. WI'09 and IAT'09 received 587 submissions (343 for WI'09 and 244 for IAT'09) to the research and industry tracks from 50 countries and regions: Algeria, Australia, Austria, Bahrain, Brazil, Canada, China, Colombia, Cyprus, Czech Republic, Denmark, Ethiopia, Finland, France, Germany, Greece, Hong Kong, India, Iran, Ireland, Israel, Italy, Jamaica, Japan, Jordan, Korea, Luxembourg, Malaysia, Mexico, New Zealand, Norway, Pakistan, Poland, Portugal, Romania. Russia, Serbia and Montenegro, Singapore, Slovakia, Spain, Sweden, Taiwan, The Netherlands, Tunisia, Turkey, UK, USA, Venezuela, and Vietnam. The submitted papers went through a rigorous reviewing process. Most of the 587 submissions were reviewed by at least three program committee members, and all the conflictive cases were revised by one program vice-chair and one program co-chair. As a result, approximately 16% of the WI'09 submissions were accepted as regular papers and 18% were accepted as short papers. For IAT'09, around 18% of the submissions were accepted as regular papers and 22% were accepted as short papers. In addition to the paper presentations at the research tracks, our technical program also features 6 invited talks, a WIC feature talk, 2 tutorials, and 18 workshops, including a doctoral workshop. We are grateful to the following distinguished invited speakers for the delivery of the invited lectures: Stefano Ceri (Politecnico di Milano, Italy), Marco Dorigo (Université Libre de Bruxelles, Belgium), Katia P. Sycara (Carnegie Mellon University, U.S.A.), Bhavani Thuraisingham (The University of Texas at Dallas, U.S.A.), Chengqi Zhang (University of Technology, Sydney, Australia), and Ronald R. Yager (Iona College, New Rochelle, NY, U.S.A.). We are also grateful to Yulin Qin (The International WIC Institute, Beijing University of Technology, China/Carnegie Mellon University, U.S.A) for the WIC feature talk. As the Web continues to grow and evolve, many new problems and challenges are being introduced. The WI-IAT workshops provide a venue and forum for contributions in specialized sub-areas of Web Intelligence and Intelligent Agent Technology, and allow authors to present new and emerging trends in methods and technologies to dedicated audiences. The organizers received 26 proposals for WI-IAT 2009 workshops, out of which 18 were accepted, representing a variety of selected special topics. The 18 workshops received 205 submissions in total. We express our sincere gratitude to the workshop chairs (Paolo Boldi and Giuseppe Vizzari) and the organizers of each workshop for their great efforts and hard work to make an exciting workshop program. It is impossible to organize any high quality conference without the enormous support and expertise of many top class researchers and leaders. We express our gratitude to the Organisation Co-Chairs Gloria Bordogna and Giancarlo Mauri. Our sincere thanks are due to all chairs, co-chairs, vice-chairs, WIC advisory board members, WIC technical committee and WI/IAT steering committee members, program committee members, reviewers, conference secretariat, Web support and volunteer team for their valuable contribution. We thank also Juzhen Dong for her support with the Cyber-Chair, and the staff at the IEEE Computer Society Press for their support in compiling the proceedings. Finally we wish to show our appreciation to the sponsors of our WI’09 and IAT’09 and we are grateful to the authors, presenters and delegates for their contribution and participation.

Tutorial 1 The Web of Data for E-Commerce in Brief A Hands-on Introduction to the GoodRelations Ontology, RDFa, and Yahoo! SearchMonkey Presenters: Martin Hepp and Michael Hausenblas (9:00-12.45) Location: room 23 Abstract In this tutorial, we will (1) explain the immediate business benefits of joining the Web of Data for Web shops, manufacturers of commodities, and service providers of any kind, (2) show how any commercial Web site can embed details of its business and offerings as RDFa metadata using the GoodRelations ontology, and (3) demonstrate the usage of the resulting data in multiple applications, namely Yahoo! SearchMonkey, queries on Semantic Web data repositories, Mashups, and the import from and export to popular Web shop software. Participants will learn how to use the GoodRelations ontology to augment Web shops and other Web applications with metadata on business entities, products and services, prices, warranty, shop locations, terms and conditions, etc. This will improve the visibility of an offering in next generation Web search engines, allow more precise search, and support partners in the value chain to extract and reuse product model data easily. At the same time, the tutorial will explain the modeling of more complex RDF patterns in RDFa. The tutorial will also serve as a self-contained introduction of what the Web of Data is, which benefits it will provide for businesses, and why now is the time to get involved. Tutorial 2 Query Log Analysis for Enhancing Web Search Presenters: Salvatore Orlando and Fabrizio Silvestri (14:00-18.25) Location: room 23 Abstract Web Search Engines have stored in their logs information about users since they started to operate. This information often serves many purposes. The primary focus of this tutorial is to introduce to the discipline of query mining by showing its foundations and by 12 Conference Program analyzing the basic algorithms and techniques that could be used to extract and to exploit useful knowledge from this (potentially) in finite source of information. Furthermore, participants to this tutorial will be given a unified view on the literature on query log analysis. Web search engines are queried by users to satisfy their information need. We will review studies analyzing how users interact with search engine systems; how can a query be considered correctly answered, and so on. We will show how search applications may benefit from this kind of analysis by analyzing popular applications of query log mining and their influence on user experience. In addition, we will review some of the most recent results in this field, where techniques enhancing both effectiveness and effciency of web search engine system are proposed. Previously submitted queries represent a very important mean for enhancing effectiveness of search systems. Query logs keep track of information regarding interaction between users and the search engine. Sessions, i.e. the sequence of queries submitted by the same users in the same period of time, can be used as a way for deriving recurring query patterns used, for instance, to give users query suggestions. Click-through data is, usually, the main mean for capturing users’ relevance feedback information. All in all, every single kind of user action (also, for instance, not clicking on a result) can be exploited to derive aggregate statistics which are very useful for the optimization of search engine effectiveness. Regarding efficiency, query logs can be a critical source of information to optimize precision of results and efficiency of different parts of search engines, whose distributed and scalable design needs to be optimized in order to support the huge volume of queries submitted every day by users. Interesting features to exploit are the query distribution, the arrival time of each query, the results that users click on, etc. We will review how such features can be exploited to optimally partition the document collection/index, caching the query results, as well as to efficient route queries in distributed Web search engines. This means that dealing with effciency in Web search engines is as important as it is dealing with user preferences and feedback to enhance effectiveness. Finally, the last part of the tutorial will, briefly, go through some of the most challenging current open problems in this field.

Who is the best doctor to cure insomnia in a nearby hospital? Where can I attend an interesting conference in my field closest to a sunny beach?" This information is available on the Web, but no software system can accept such queries nor compute the answer. We hereby propose search computing as a new multi-disciplinary science which will provide the abstractions, foundations, methods, and tools required to answer these and many similar queries. While state-of-art search systems answer generic or domain-specific queries, search computing enables answering questions via a constellation of dynamically selected, cooperating, search services. Search computing requires innovation in software principles, languages, interfaces, and protocols, as well as contributions from other sciences such as mathematics, operations research, psychology, sociology, economical and legal sciences. Biography Stefano Ceri is Professor of Database Systems at the Dipartimento di Elettronica e Informazione (DEI), Politecnico di Milano; he was visiting professor at the Computer Science Department of Stanford University between 1983 and 1990. He is vice-chairman of Alta Scuola Politecnica, a school of excellence for master-level students which is jointly organized by Politecnico di Milano and Politecnico di Torino. He is an associated editor of several international journals, co-editor in chief of the book series "Data Centric Systems and Applications" (Springer-Verlag), author of over 250 articles on International Journals and Conference Proceedings, and co-author of nine international books. His research interests are focused on extending database technology to incorporate data distribution, deductive and active rules, object orientation, and XML query languages, as well as on design methods for data-intensive WEB sites, stream reasoning, and search computing. He is co-inventor of WebML, a model for the conceptual design of Web applications, and co-founder of Web Models, a startup of Politecnico di Milano focused on WebML commercialization by means of the product WebRatio. He has been responsible of several EU-Funded Projects projects, including being awarded in July 2008 an IDEAS Advanced Grant, funded by the European Research Council (ERC), on "Search Computing" (2008-2013). 41 Conference Program Title: Swarm-bots and Swarmanoid: Two experiments in embodied swarm intelligence Marco Dorigo Université Libre de Bruxelles, Belgium Abstract Swarm intelligence is the discipline that deals with natural and artificial systems composed of many individuals that coordinate using decentralized control and self-organization. In particular, it focuses on the collective behaviors that result from the local interactions of the individuals with each other and with their environment. The characterizing property of a swarm intelligence system is its ability to act in a coordinated way without the presence of a coordinator or of an external controller. Swarm robotics could be defined as the application of swarm intelligence principles to the control of groups of robots. In this talk I will discuss results of Swarm-bots, an experiment in swarm robotics. A swarm-bot is an artifact composed of a swarm of assembled s-bots. The s-bots are mobile robots capable of connecting to, and disconnecting from, other s-bots. In the swarm-bot form, the s-bots are attached to each other and, when needed, become a single robotic system that can move and change its shape. S-bots have relatively simple sensors and motors and limited computational capabilities. A swarm-bot can solve problems that cannot be solved by s-bots alone. In the talk, I will shortly describe the s-bots hardware and the methodology we followed to develop algorithms for their control. Then I will focus on the capabilities of the swarm-bot robotic system by showing video recordings of some of the many experiments we performed to study coordinated movement, path formation, self-assembly, collective transport, shape formation, and other collective behaviors. I will conclude presenting initial results of the Swarmanoid experiment, an extension of swarm-bot to 3-dimensional environments.

Abstract Teams are a form of organizational structure where the team members engage in information exchanges in order to fulfill team goals. The activities that the team engages in are inter-dependent and usually involve gathering, interpreting and exchanging information; creating and identifying alternative courses of action; choosing among alternatives by considering different viewpoints of team members; choosing among decision alternatives and monitoring the consequences of the decision. Effective teams achieve goals and accomplish tasks that otherwise would not be achievable by groups of uncoordinated individuals. While previous work in teamwork theory has focused on describing ways in which humans coordinate their activities, there has been little previous work on which of those specific activities, information flows and team performance can be enhanced by being aided by software agents. Recent interest in supporting emergency response teams, military interest in operations other than war, and coalition operations, motivates the need for studies that examine agent aiding strategies and their effect on human team performance. This talk will present (a) characteristics and challenges of human teamwork that have not been well studied to date, such as decentralization and self-organization, (b) results of studies of human-only teamwork performance that incorporate these challenges in order to establish a baseline, and (c) identification of fruitful ways for agents to aid human teams with these characteristics. In particular, we will focus on teams that operate in time stressed environments without previous training together. We will also present results of studies where software agents provided decision support for human teams in the performance of a variety of tasks and under different environmental and task constraints. We will close with open challenges and research problems in agent aiding of human teamwork.

Abstract Data mining is the process of posing queries and extracting patterns, often previously unknown from large quantities of data using pattern matching or other reasoning techniques. Data mining has many applications in security including for national security as well as for cyber security. The threats to national security include attacking buildings, destroying critical infrastructures such as power grids and telecommunication systems. Data mining techniques are being investigated to find out who the suspicious people are and who is capable of carrying out terrorist activities. Cyber security is involved with protecting the computer and network systems against corruption due to Trojan horses, worms and viruses. Data mining is also being applied to provide solutions such as intrusion detection and auditing. The first part of the presentation will discuss my joint research with Prof. Latifur Khan and our students at the University of Texas at Dallas on data mining for cyber security applications For example; anomaly detection techniques could be used to detect unusual patterns and behaviors. Link analysis may be used to trace the viruses to the perpetrators. Classification may be used to group various cyber attacks and then use the profiles to detect an attack when it occurs. Prediction may be used to determine potential future attacks depending in a way on information learnt about terrorists through email and phone conversations. Data mining is also being applied for intrusion detection and auditing. Other applications include data mining for malicious code detection such as worm detection and managing firewall policies. This second part of the presentation will discuss the various types of threats to national security and describe data mining techniques for handling such threats. Threats include non real-time threats and real-time threats. We need to understand the types of threats and also gather good data to carry out mining and obtain useful results. The challenge is to reduce false positives and false negatives. The third part of the presentation will discuss some of the research challenges. We need some form of real-time data mining, that is, the results have to be generated in real-time, we also need to build models in real-time for real-time intrusion detection. Data mining is also being applied for credit card fraud detection and biometrics related applications. While some progress has been made on topics such as stream data mining, there is still a lot of work to be done here. Another challenge is to mine multimedia data including surveillance video. Finally, we need to maintain the privacy of individuals. Much research has been carried out on privacy preserving data mining. In summary, the presentation will provide an overview of data mining, the various types of threats and then discuss the applications of data mining for malicious code detection, cyber security and national security. Then we will discuss the consequences to privacy.

Yager Iona College, New Rochelle, NY, U.S.A. Abstract The recent development of Web 2.0 has provided an enormous increase in human interactions across all corners of the earth. One manifestation of this is the growth of computer mediated social networks. Many notable Web 2.0 applications such as Facebook, Myspace and LinkedIn are social networks. Relational networks are becoming an important technology for modeling these types of social networks and the type of collaborative intelligence that arises from these interactions. Our goal here is to enrich the domain of social network modeling by introducing ideas from fuzzy sets and related granular computing technologies to provide a bridge between a human network analyst's linguistic description of social network concepts and the formal model of the network.

The existing trading agent research mainly focuses on simulation using artificial data. As a result, the actionable capability of developed trading strategies is often limited, and the trading agents therefore lack power. Actionable trading strategies can empower trading agents with workable decision-making in real-life markets. The development of actionable strategies is a non-trivial task, which needs to consider real-life constraints and organisational factors in the market. In this talk, we first analyse such constraints on developing actionable trading strategies for trading agents and propose a trading strategy development framework for trading agents. We then develop a series of trading strategies for trading agents through optimising, enhancing and discovering actionable trading strategies. We demonstrate working case studies using agent mining technology in real market data. These approaches, and their performance, are evaluated from both technical and business perspectives. These evalualtions clearly show that the development of trading strategies for trading agents, using our approach, can lead to smart decisions for brokerage firms and financial companies.

Abstract In the early stage of artificial intelligence (AI), AI very closed to then modern cognitive psychology based on the recognition that both computer and human brain are information processing machines meeting the requirements to show intelligence. It seems that the similar trend appears again today between Web Intelligence (WI) and Brain Informatics (BI) based on the recognition that both World Wide Web (the Web) and the human brain are informational huge open systems meeting the requirements to deal with scalable, dynamically changing, distributed, incomplete and inconsistent information, and the advancement both in the Web (e.g., semantic Web and human-level wisdom-Web computing) and in BI (e.g., advanced information technologies for brain science and non-invasive neuroimaging technologies, such as functional magnetic resonance imaging (fMRI)). ACT-R is a theory and model of computational cognitive architecture, which consists of functional modules, such as declarative knowledge module, procedural knowledge module, goal module and input (visual, aural), output (motor, verbal) modules. Information can be proposed parallel inside and among the modules, but has to be sequentially if it needs procedural module to coordinate the behavior across modules. At the International WIC Institute (WICI), we are trying to introduce this kind of architecture and the mechanism of activation of the units in declarative knowledge module into our wisdom-Web computing system. Based on or related to ACT-R, theories and models that are with very close relation to WI have also been developed, such as threaded cognition for concurrent multitasking, cognitive agents, human-Web interaction (e.g., SNIT-ACT (Scent-based navigation and information foraging in the ACT cognitive architecture). At the WICI, we are also working on the user behavior and reasoning on the Web by eye-tracker and fMRI. Human can perceive the real world under many levels of granularity (i.e., abstraction) and can also easily switch among granularities. By focusing on different levels of granularity, one can obtain different levels of knowledge, as well as in-depth understanding of the inherent knowledge structure. At the WICI, we are taking Granular Reasoning (GrR) as a human intelligence inspired methodology and developing specific methods for a reasoning process in a variable precision at Web scale. All of above will be discussed in my talk as examples of various levels from BI to WI to show the trend of close interacting between BI and WI, which will benefit both WI and BI researches. Biography Yulin Qin is a professor at International WIC Institute (WICI) at Beijing University of Technology, and a senior research psychologist in the department of psychology, Carnegie Mellon University. Professor Qin received M.E. in computer science and engineering from Beijing University of Aeronautics and Astronautics, and Ph.D. in cognitive psychology at Carnegie Mellon University. His research interests include cognitive psychology, cognitive neuroscience and Web Intelligence, and currently focus on the neural basis of ACT-R, a computational cognitive model, and its relation with Web Intelligence. 47 Conference Program Organizing Committee WI'09 and IAT'09 Conference Organization Conference Chair: Gabriella Pasi, Università degli Studi di Milano Bicocca, Milano, Italy Program Chair: Ricardo Baeza-Yates, Yahoo!
