Preface

After 50 years of research in Artificial Intelligence (AI), the dream of intelligent machines that use sophisticated and advanced approaches is becoming a reality. AI researchers have already created systems capable of tackling complicated and challenging problems. Scientists have developed analytical models and corresponding systems which can mimic human behavior and cognition, they can understand speech, beat experts human chess players, and countless other feats that can have a potential impact in our everyday lives. It is a fact that humans are a species that learn by training plus trial and error, so it can be considered rational to see AI more as a blessing and less as an inhibition. On the other hand the misuse of AI technology is always a potential.The 8th AIAI conference is supported and sponsored by the International Federation for Infor-mation Processing (IFIP). It is the official conference of the IFIP’s Working Group 12.5 “Artificial Intelligence Applications”. IFIP was founded in 1960 under the auspices of UNESCO, following the first World Computer Congress held in Paris the previous year. The 1st AIAI conference was held in Toulouse/France in 2004 and since then it has been held annually offering scientists the chance to present the achievements of AI applications in various fields. This Springer volume belongs to the IFIP AICT series. It contains the papers that were accepted to be presented orally at the main event of the 8th AIAI conference and the papers accepted for the 8 workshops that were organized as parallel events, namely: the 2nd AIAB, the 1st AIeIA, the 2nd CISE, the 1st COPA, the 1st IIVC, the 3rd ISQL, the 1st MHDW and the 1st WADTMB. More details on the workshops will be given in the following paragraphs.The 8th AIAI conference was held during 27-30 of September 2012 at the Sithonia penin-sula of Halkidiki/Greece. The diverse nature of papers presented demonstrates the vitality of AI computing approaches and proves the very wide range of AI applications as well. On the other hand, this volume contains basic research papers, presenting variations and extensions of several existing methodologies. The response to the call for papers was more than satisfactory with 98 papers initially submitted to the main event. All papers have passed through a peer review process by at least 2 indepen-dent academic referees. Where needed a third referee was consulted to resolve any conflicts. In the 8th AIAI conference, 43.9% of the submitted manuscripts (totally 44) were published in the Proceedings as full papers whereas 5.1% as short ones. The authors of accepted papers of the main event come from 17 different countries, namely: Belgium, Croatia, Cyprus, Czech Republic, France, Germany, Great Britain, Greece, Iran, Italy, Pakistan, Poland, Portugal, Romania, Russia, Tunisia, United States of America.

Three keynote speakers were invited to lecture to the 8th AIAI conference. 1. Dr. Danil Prokhorov from Toyota Research Institute NA, Ann Arbor, Michigan will deliver a

talk with a title “Computational Intelligence in Automotive Applications”. 2. Professor David Robertson from University of Edinburgh will talk on “Knowledge Engi-

neering on a Social Scale”.

Monotonicity issues in fuzzy modelling, machine learning and decision making

In many modelling problems, there exists a monotone relationship between one or more of the input variables and the output variable, although this may not always be fully the case in the observed input-output data due to data imperfections. Monotonicity is also a common property of evaluation and selection procedures. In contrast to a local property such as conti-nuity, monotonicity is of a global nature and any violation of it is therefore simply unacceptable. We explore several problem settings where monotonicity matters, including fuzzy modelling, machine learning and decision making.

Computational Intelligence in Automotive Applications

Computational intelligence is traditionally understood as encompassing artificial neural, fuzzy and evolutionary methods and associated computational techniques. Different CI methodolo-gies often get combined with each other and with non-CI methods to achieve superior results in various applications. In this presentation I will discuss CI methodological issues and illustrate them with several applications from the areas of vehicle manufacturing, vehicle system moni-toring and control, as well as active safety. These will be representative of CI applications in the industry and beyond. I will also discuss some lessons learned about successful and yet-to-be-successful industrial applications of CI.

Knowledge Engineering on a Social Scale

For much of its history, formal knowledge representation has aimed to describe knowledge independently of the personal and social context in which it is used, with the advantage that we can automate reasoning with such knowledge using mechanisms that also are context inde-pendent. This sounds good until you try it on a large scale and find out how sensitive to context much of reasoning actually is. Humans, however, are great hoarders of information and sophis-ticated tools now make the acquisition of many forms of local knowledge easy. The question is: how to combine this beyond narrow individual use, given that knowledge (and reasoning) will inevitably be contextualised in ways that may be hidden from the people/systems that may interact to use it? This is the social side of knowledge representation and automated reasoning. I will discuss how the formal reasoning community has adapted to this new view of scale, using examples from my own research and that of others.

Tutorials

Dr Tatiana Tambouratzis

Associate Professor, Dept. of Industrial Management & Technology, University of Piraeus, Greece

Identification of Key Music Symbols for Optical Music Recognition and On-Screen Presentation

A novel optical music recognition (OMR) system is put forward, where the custom-made on-screen presentation of the music score (MS) is promoted via the recognition of key music symbols only. The proposed system does not require perfect manuscript alignment or noise removal. Following the segmentation of each MS page into systems and, subsequently,into staves, staff lines, measures and candidate music symbols (CMS’s), music symbol recognition is limited to the identification of the clefs, accidentals and time signatures. Such an implemen-tation entails significantly less computational effort than that required by classic OMR systems, without an observable compromise in the quality of the on-screen presentation of the MS. The identification of the music symbols of interest is performed via probabilistic neural networks (PNN’s), which are trained on a small set of exemplars from the MS itself. The initial results are promising in terms of efficiency, identification accuracy and quality of viewing.

Negotiations in Multi-Agent Systems

The increasing complexity of real-world problems demands special support for distributed collaborative problem solving. Multi-agent systems (MAS) are lightweight distributed systems that combine interaction, coordination and distribution of computation for collaborative problem solving. Negotiation, i.e. “the process by which a group of agents come to a mutu-ally acceptable agreement on some matter” is very useful for managing dynamic dependen-cies between agents. The aim of this tutorial is to introduce the problems and challenges of applying negotiations in MAS using examples from different areas including e-business and disaster management.

Workshops

1st Mining Humanistic Data Workshop MHDW 2012

Program chairs:Spyros Sioutas, Department of Informatics, Ionian University, GreeceKatia Lida Kermanidis, Department of Informatics, Ionian University, GreeceIoannis Karydis, Department of Informatics, Ionian University, Greece

The abundance of available data that is retrieved from or is related to the areas of Humanities chal-lenges the research community in processing and analyzing it. The aim is two-fold: on the one hand, to extract knowledge that will help understand human behavior, creativity, way of thinking, reasoning, learning, decision making, socializing; on the other hand, to exploit the extracted knowledge by incorporating it into intelligent systems that will support humans in their everyday activities. The nature of humanistic data can be multimodal, dynamic, time and space-dependent, and highly complicated. Translating humanistic information, e.g. behavior, state of mind, artistic creation and linguistic utterance, into numerical or categorical low-level data is a significant chal-lenge on its own. New mining techniques, appropriate to deal with this type of data, need to be proposed and existing ones adapted to its special characteristics. The workshop aims to bring together interdisciplinary approaches that focus on the application of innovative as well as existing mining and knowledge discovery techniques (like decision rules, decision trees, association rules, clustering, filtering, learning, classifier systems, neural networks, support vector machines, prepro-cessing, post processing, feature selection, visualization techniques) to data derived from all areas of Humanistic Sciences, e.g. linguistic, historical, behavioral, psychological, artistic, musical, educa-tional, social etc.

1st Conformal Prediction and its Applications Workshop COPA 2012

Program chairs:Harris Papadopoulos, Frederick University, CyprusAlex Gammerman, Royal Holloway, University of London, UK Vladimir Vovk, Royal Holloway, University of London, UK

Quantifying the uncertainty of the predictions produced by classification and regression techniques is an important problem in the field of Machine Learning.

of confidence. The methods developed based on this framework produce well-calibrated confidence measures for individual examples without assuming anything more than that the data are generated independently by the same probability distribution (i.i.d.). Since its development the framework has been combined with many popular techniques, such as Support Vector Machines, k-Nearest Neigh-bours, Neural Networks, Ridge Regression etc., and has been successfully applied to many challenging real world problems, such as the early detection of ovarian cancer, the classification of leukaemia subtypes, the diagnosis of acute abdominal pain, the assessment of stroke risk, the recognition of hypoxia in electroencephalograms (EEGs), the prediction of plant promoters, the prediction of network traffic demand, the estimation of effort for software projects and the backcalculation of non-linear pavement layer moduli. The framework has also been extended to additional problem settings such as feature selection, outlier detection, change detection in streams and active learning. The aim of this workshop is to serve as a forum for the presentation of new and ongoing work and the exchange of ideas between researchers on any aspect of Conformal Prediction and its applications.

2nd Artificial Intelligence Applications in Biomedicine Workshop AIAB 2012

Program Chairs:Harris Papadopoulos, Frederick University, CyprusEfthyvoulos Kyriacou, Frederick University, CyprusIlias Maglogiannis, University of Central Greece, GreeceGeorge Anastassopoulos, Democritus University of Thrace, Greece

Recent technological advances in computer science and biomedicine facilitated the development of complex biomedical systems including sophisticated medical imaging, signal processing systems and computer based decision support tools, assisting diagnosis for better delivery of health care services. Meanwhile, applications of Machine Learning, Neural Computing, Expert Systems, Fuzzy Logic and Evolutionary Computing in biomedicine are continuously emerging. Therefore AI tools and techniques are a vital part of modern computer based systems that handle medical data. The aim of this workshop is to serve as a forum for the presentation of new and ongoing work and the exchange of ideas between researchers interested in the application of AI in any aspect of biomedi-cine and electronic healthcare.

The CISE workshop focuses on theoretical and applied research related to the utilization of Computational Intelligence techniques in Software Engineering, targeting the provision of alternative, interdisciplinary approaches for tackling problems found in Software Engineering. The aim of the workshop is to host research papers that present practical solutions to emerging Software Engineering issues by applying Computational Intelligence methods. The workshop is associated with research and development advances in many fields of Software Engineering and particularly the study, analysis, design, modelling, implementation and application of Computational Intelligence techniques that tackle significant Software Engineering problems. The topics of interest call, especially, for papers with theoretical and practical importance, while research papers reporting emerging and innovative ideas are also highly desirable. Nature-inspired Computational Intelligence methodologies demonstrate adaptive behaviour and learning ability. As such, they can be effectively utilized to address convoluted problems and applications in real-world environments, where traditional methodologies and approaches find highly complex and difficult to tackle. Particularly, techniques associated with learning, reasoning, optimization and decision making, such as Fuzzy Systems, Artificial Neural Networks, Evolutionary Computing, Swarm Intelligence, Artificial Immune Systems, Dempster-Shafer Theory, Chaos Theory and Multi-valued Logic, may be applied in real-world conditions and serve the Software Engineering community. The integration of Software Engineering with Computational Intelligence is very important to both academic and research communities as well as to software industries. In fact, software development teams adopt a variety of conceptual and algorithmic practices that are combined with Computational Intelligence methods within various areas of Software Engineering, such as Project Management, Risk Analysis, Testing, Cost Estimation and Failure Modelling. Computational Intelligence also provides the means for more precise measurement of software metrics and more effective handling of uncertainty or ambiguity of information.

1st Workshop on Algorithms for Data and Text Mining in Bioinformatics WADTMB 2012

Program chairs:Athanasios Tsakalidis, University of Patras, GreeceChristos Makris, University of Patras, Greece

The aim of this workshop is to bring together researchers that are interested in designing, devel-oping and applying efficient data and text mining techniques for discovering the underlying knowl-edge existing in biomedical data. Bioinformatics is an emerging field of science that plays a crucial role in managing, processing and computationally analyzing biological and biomedical data such as sequences, gene expressions and pathways. Biomedical researchers face the fundamental issue of making efficient use of a tremendous amount of data that is produced and deposited in public, in order to improve and enhance their understanding of complex biomedical systems. As a result, there is an urgent need for novel efficient computational methods and tools to facilitate the process of managing and discovering useful patterns and knowledge from these large biomedical data repositories. Data mining plays an essential role in Bioinformatics since it is the process of auto-matic discovering of hidden meaningful and useful patterns and correlations in large amounts of

data. Data mining approaches provide tools for dealing with biomedical problems such as protein structure prediction, efficient clustering of gene expression data and efficient gene classification. Also, of significant importance is biomedical text mining, that is the process of automatically exploiting enormous amount of knowledge available in biomedical literature such as automatic extraction of protein-protein interactions, named entity recognition, text classification and termi-nology extraction. Although considerable progress has been made recently in these areas, many of the fundamental issues in bioinformatics such as the ability of completely automatic extraction of useful information from structured or unstructured data remain open challenging tasks. The proposed workshop aims at giving the opportunity to researchers to present their original work on issues pertaining to data and text mining in bioinformatics. We encourage papers that present novel mining techniques and tools for the following tasks: Biomedical Database management, Gene expression analysis, Protein structure prediction, Prediction of protein-protein interaction, Text Mining in Biomedical Literature, Web Mining Bioinformatics applications.

1st AI in Education Workshop: Innovations and Applications AIeIA 2012

Program chairs:Achilleas Kameas, Hellenic Open University, GreeceAntonia Stefani, Hellenic Open University, Greece

The use of Information Technologies in Education has been extensively researched in the past few years with a plethora of solutions already in use by numerous organizations. However, user adop-tion difficulties in real situations has only demonstrated that the primary need is the design of tech-niques and tools that have a real practical impact and facilitate a paradigm shift in the educational model. This shift in the Educational paradigm is focused on knowledge construction, which will enhance, not replace, the classic information transfer paradigm. The management of knowledge in Educational contexts enables social learning, active collaboration among human peers and espe-cially enhanced presence. The next generation of Information technology tools in Education will facilitate the transformation of information into knowledge, by humans as well as -progressively- by software agents, providing the electronic underpinning for a global society in business, govern-ment, research, science and education. Artificial Intelligence can be a major enabling technology for this type of Educational paradigm. AI’s application in Education is one of the oldest yet still prom-ising and most exciting research topics with a significant practical impact. Especially Knowledge Management has yet much to offer in the way computing in education is used. The goal of the Work-shop is to assess the impact of Knowledge Management to current Educational practices and more significantly, to identify opportunities, benefits and drawbacks to current practices that will permit progress beyond the state of the art. The Workshop aims at addressing theoretical and practical issues concerning new trends in knowledge discovery, acquisition representation, sharing and reuse.By accepting original contributions from platform and tool providers, researchers and system devel-opers from academia and industry it soughts to be a forum for exchanging ideas and experiences, sharing of best practices and fostering further development in the application of AI in Education.

1st Intelligent Innovative Ways for Video-to-video Communication in Modern Smart Cities Workshop IIVC 2012

Program chairs:Ioannis P. Chochliouros, Hellenic Telecommunications Organizations (OTE) S.A, GreeceIoannis M. Stephanakis, Hellenic Telecommunications Organizations (OTE) S.A, GreeceVishanth Weerakkody, Brunel University, UKNancy Alonistioti, National & Kapodistrian University of Athens, Greece

The Digital Agenda for Europe intends to sustain fast and ultrafast Internet access as well as the development and operation of several “open platforms” able to provide new and innovative prod-ucts and related services, especially in the framework of the Future Internet (FI). In the present context, both citizens and legal entities (organizations, enterprises-companies, (state) authori-ties, etc.) in urban environment are facing with a multiplicity of challenges that appropriate invest-ments -or properly selective initiatives- in pioneering ICT-based solutions can help “to address and to promote innovative responses”, especially those based on user-driven initiatives. Of particular importance become various activities aiming to develop modern solutions or facilities/services of higher quality in communications that should make a beneficial and really effective use of the wider context of the Internet of the Future. Until today, user-driven open innovation methodologies have proven that they can drastically improve the efficiency of the innovation process by bridging between R&D and market entry supporting better and faster take-up of R&D results. In this scope, they are very rapidly becoming the new mainstream method of innovating. Living Labs are specific examples of such open innovation environments in real-life settings, in which user-driven innova-tion is fully integrated within the co-creation process of new services, products and societal infra-structures.Cities (or urban areas) are continuously faced with major challenges that require investment in inno-vative solutions (particularly the ICT-based ones) to improve the quality and efficiency of their infra-structures and services offered. Some anticipate and are “leaders” in adopting smarter development models and may perform a kind of pioneering role in engaging the user in the expected innova-tion process. Building upon existing user-driven innovation initiatives in Europe, the critical aim is to ensure a wider implementation of open platforms for the provision of Internet-enabled services in cities and thus to include an active involvement of citizens. These platforms should be able to develop “innovation ecosystems” accelerating the move towards “smart” cities” and providing a wide range of opportunities for new, higher quality, and sustainable services for citizens and busi-nesses as well. In fact, this also delimits the essential framework that is actually taken into account the LiveCity PSP-ICT Project (Grant Agreement No.297291) effort aiming, among other issues, to the development and the operation of suitable applied initiatives (through pilot actions) with the aim of accelerating the uptake of innovative Internet-based technologies and services in cities. These apply user-driven open innovation methodologies across networks of smart cities and may combine: (i) User-driven open innovation, (ii) Connected smart cities, and (iii) Internet-based services. In this scope it should be a matter of particular importance for the LiveCity Project to “identify” channels

and or other means for potential interaction with related innovative and extended ecosystems, such as Living Labs, intending to “bridge” the gap between the development of Internet-based technolo-gies and their rapid uptake in new services.

3rd Intelligent Systems for Quality of Life information Services Workshop ISQL 2012

Program chair:Kostas Karatzas, Aristotle University of Thessaloniki, GreeceProgram vice-chairs:Lazaros Iliadis, Democritus University of Thrace, Greece Mihaela Oprea, University Petroleum-Gas of Ploiesti, Romania

Quality of Life (QoL) is directly related to environmental pressures and conditions, including air quality, pollen, drinking and bathing water quality, noise pollution, waste production, energy consumption, nutrition and many others. Intelligent systems collect data about the environ-ment’s status and quality, at the individual user and business level, through the use of participa-tory environmental sensing and available ICT and web 2.X technologies. Computational intelli-gence methods are particularly suitable for environmental modeling, knowledge extraction and generation of knowledge intensive e-services content, thus being necessary for the development of QoL information services. On the other hand, the developments in ICT make environmental data & services ubiquitous. The plethora of patterns of everyday life, as well as the availability of various ICT that are interwoven to the urban web, lead to intelligent, personalized and yet easily generalized ways for monitoring, modeling and managing environmental systems and conditions. It is therefore evident that services, systems, applications and algorithms dealing with everyday utility for the indi-vidual, are expected to play an important role in supporting QoL. On this basis, QoL environmental information services are expected to make use of personalized access and interactivity to multi-modal information, based on user preferences and semantic concepts or human-machine interface systems utilizing information on the affective state of the user. The proposed workshop will address intelligent methods for analyzing and modeling environmental systems and conditions, with the aim to serve the everyday needs of citizens under various QoL states. Human centric approaches in environmental information services will also be addressed, as they require intelligent, knowledge-centric methods and tools, that are flexible, adaptable to environmental problems, and perform better in terms of knowledge mapping and system behavior reproduction.
