He has lectured and consulted worldwide. He can be reached at jliebowitz@umuc.edu.

Knowledge management and e-learning have synergistic effects. They both contain elements of leveraging knowledge internally and externally, and both could add to the strategic intelligence of the organization. The combination of these two areas is just starting to evolve, per the evidence of the Knowledge Management and E-Learning Journal and the recent book publication of "Knowledge Management and E-Learning" (Liebowitz and Frank, eds., Taylor & Francis/CRC Press, 2011). Closer attention is warranted in the integration of these fields in order to advance the current state-of-the-art. The presentation will talk about these areas from a strategic intelligence framework, and will show examples of how the theory can be translated into practice.


Keynote Lecture 2
Accelerating Scientists' Knowledge Turns
Carole Goble
University of Manchester

Brief Bio
Carole Goble is a full professor in the School of Computer Science at the University of Manchester. She researches semantic technologies, distributed systems, data integration and social computing to solve information management problems for life scientists and other scientific disciplines.
She directs the myGrid e-Science consortium (http://www.mygrid.org.uk) which focuses on automated workflow-based scientific pipelines and e-laboratories for research and researchers.
She is well known for turning research into production software and services such as: the Taverna scientific workflow system; the myExperiment crowd-sourced workflow sharing platform; the BioCatalogue socially curated catalogue of web services; the SEEK data/models sharing platform for pan-European Systems Biology; and the MethodBox for socially sharing statistical methods and survey data. A partner in the UK's Open Middleware Infrastructure Institute and Software Sustainability Institute, she is currently building infrastructure for several EU scientific programmes in Systems Biology, Biodiversity, Astro-Physics, Astronomy and Digital Library preservation. In 2008 she received the inaugural Microsoft Jim Gray award for outstanding contributions to e-Science and in 2010 she was elected a Fellow of the Royal Academy of Engineering.

Science is knowledge work, cumulatively building on prior results. In particular scientific method and scholarly communication are about facilitating "knowledge turns" - that is, the turning of observation and hypothesis through experimentation, comparison, and analysis into new, pooled knowledge. Turns depend on the flow and availability of knowledge.

They also depend on scientists coordinating and collaborating, and in particular a "long tail" of small researcher units who contribute to, and benefit from online resources and the accumulated pool of know-how, know-what and know-why. My own research and tools - scientific workflows and services, social crowd-sourcing and sharing, and semantic technologies - focus on aiding these "long tail scientists" to accelerate knowledge turns, including the development of community ontologies.

Knowledge turns must get faster. Long tail scientists are wrestling with vast, new scales of information, rapid changes in data, richly interconnected knowledge and collaboration/coordinations. Knowledge practices work within the social and cultural systems that scientists currently operate in if they are to be truly adopted and make any useful impact. However, our scientists are operating in outdated models of scholarly publishing. Computational and data intensive methods are on the increase but much of the scientific knowledge generated is not readily available, reproducible, reusable or repeatable.

To really accelerate knowledge and liberate our scientific long-tail we need a greater openness to increase productivity, widen equity and offer ethical transparency. Ecosystems of Research Objects could be the future currency of scholarly knowledge; that is, packaged, interconnected and citable units of active knowledge combining remote and local source data, results data, methods, protocols, presentations, lab books, experts.

So what are scientific knowledge assets? What are the trends and challenges knowledge flows in science? How would we preserve, curate, reproduce or publish complex, online digital Research Objects? What are the prospects for the "Executable Publication"? What are social issues that speed up and slow down knowledge turns? How can we get scientists to share? How can you help?


Keynote Lecture 3
Probabilistic Modeling, Projection Pursuit and Blind Source Separation
Mayer Aladjem
Ben-Gurion University of the Negev

Brief Bio
Mayer Aladjem received the M.Sc. degree in electrical engineering and applied mathematics and PhD degree in electrical engineering from the Technical University, Sofia, Bulgaria. He was an associate Professor of Biomedical Cybernetics in Bulgarian Academy of Sciences. He joined the Department of Electrical and Computer Engineering at Ben-Gurion University of the Negev, Israel in 1990 and he is currently an associate Professor in this department. His research interests are Statistical pattern recognition; Neural networks for pattern recognition; Multivariate density estimation; Blind source separation; Independent component analysis; Feature extraction, reduction, and analysis; Applications in signal and image processing. Prof. Aladjem served as Chairman of the International Symposium on Advances in intelligent data analysis (AIDA'2001), Bangor, Wales, U.K. and was Guest Editor of the Special Edition: "Advanced Data Analysis and Biomedical Applications" in the journal Knowledge-Based Intelligent Engineering Systems. He is currently an Associate Editor of the journal Pattern Analysis& Applications. For more information see http://www.ee.bgu.ac.il/~aladjem/

In this talk I will present methods for estimation (approximation) of n-variate probability density functions using a statistical techniques named projection pursuit (PP) and independent component analysis (ICA). We seek a Gaussian mixture model (GMM) of an n-variate probability density function. Usually the parameters of GMMs are determined in the original n-dimensional space by optimizing a maximum likelihood (ML) criterion. A practical deficiency of this method of fitting GMMs is its poor performance when dealing with high-dimensional data since a large sample size is needed to match the accuracy that is possible in low dimensions. We will present recent methods for fitting the GMM based on the PP and ICA strategies. These GMMs are highly constrained and hence its ability to model structure in subspaces is enhanced, compared to a direct ML fitting of a GMM in high dimensions. The comparisons with ML fitting of GMM in n-dimensions show that the PP and ICA methods are attractive choices for fitting GMMs using small sizes of training sets.
An important application of these methods is blind source separation (BSS). I will present several examples for BSS. The presented methods can be applied to knowledge discovery, information retrieval, mining high-dimensional data, data visualization and many other practical problems.

He is now project coordinator of the EU Integrated Project NoTube concerned with integration of Web and TV data with the help of semantics and was previously Scientific Director of the EU Network of Excellence "Knowledge Web".
For more information see http://www.cs.vu.nl/~guus/

With the advent of the Web and the efforts towards a Semantic Web the nature of knowledge engineering has changed drastically. In this talk I will discuss some guiding principles for knowledge engineering on a Web scale. We illustrate these principles with examples from knowledge-intensive Web applications in areas such as digital heritage, social TV, and e-humanities. Web-based knowledge engineering is a key component of the emerging discipline of Web Science, which studies the virtual world as a relatively new phenomenon for which scientific laws and theories of the physical world do not always hold.

The notion of organized complexity, as defined by Gerald Weinberg, seems to be a good indication for the kind of artifacts that professionals in organization and information system science are dealing with. As Edsger Dijkstra already pointed at, our primary task in dealing with those artifacts is to manage intellectually their inherent complexity. Five intellectual techniques will be presented and discussed that provide adequate help in mastering complexity: 1) separation of concerns, 2) use of abstraction, 3) devising proper concepts, 4) verification by instantiation, and 5) validation from ontology. Particular emphasis will be put on the third one, since it appears that many currently popular methods in systems development lack a proper conceptual basis. As a step towards improving this situation, ideas about a new theoretical foundation of information systems are presented and discussed.
