Co-Creation and Collaboration in a Virtual World: A 3D Visualization
Design Project in Second Life

One of the most successful and useful implementations of 3D virtual worlds
is in the area of education and training. This paper discusses the use of
virtual worlds in education and describes an innovative 3D visualization
design project using one of the most popular virtual worlds, Second Life.
This ongoing project is a partnership between IBM and three universities
in the United States: the University of Nebraska-Lincoln, Iowa State
University, and Wright State University. More than 400 MBA students have
participated in this project by completing a creative design project that
involves co-creation and collaboration in Second Life. The MBA students
from the three universities worked in pairs to create designs to represent
concepts related to IBM Power Systems, a family of IBM servers. The paper
discusses observations and reflections on the 3D visualization design
project. The paper concludes with a discussion of future research
directions in applying virtual worlds in education.

RESEARCH PAPER ONE
Transforming Activity-Centric Business Process Models into
Information-Centric Models for SOA Solutions
Rong Liu, IBM T.J. Watson Research Center, USA
Frederick Y. Wu, IBM T.J. Watson Research Center, USA
Santhosh Kumaran, IBM T.J. Watson Research Center, USA
Much of the prior work in business process modeling is activity-centric.
Recently, an information-centric approach has emerged, where a business
process is modeled as the interacting lifecycles of business entities. The
benefits of this approach are documented in a number of case studies. In
this paper, the authors formalize the information-centric approach and
derive the relationships between the two approaches. The authors formally
define the notion of a business entity, provide an algorithm to transform
an activity-centric model into an information-centric process model, and
demonstrate the equivalence between these two models. Further, they show
the value of transforming from the activity-centric paradigm to the
information-centric paradigm in business process componentization and
Service-Oriented Architecture design and also provide an empirical
evaluation.

RESEARCH PAPER TWO
An Integrated Query Relaxation Approach Adopting Data Abstraction and
Fuzzy Relation
Soon-Young Huh, Korea Advanced Institute of Science and Technology, Korea

This paper proposes a cooperative query answering approach that relaxes
query conditions to provide approximate answers by utilizing similarity
relationships between data values. The proposed fuzzy abstraction
hierarchy (FAH) represents a similarity relationship based on the
integrated notion of data abstraction and fuzzy relations. Based on FAH,
the authors develop query relaxation operators like query generalization,
approximation, and specialization of a value. Compared with existing
approaches, FAH supports more effective information retrieval by
processing various kinds of cooperative queries through elaborate
relaxation control and providing ranked query results according to fitness
scores. Moreover, FAH reduces maintenance cost by decreasing the number of
similarity relationships to be managed.

RESEARCH PAPER THREE
Accelerating Web Service Workflow Execution via Intelligent Allocation of
Services to Servers
Konstantinos Stamkopoulos, University of Ioannina, Greece

The appropriate deployment of web service operations at the service
provider site plays a critical role in the efficient provision of services
to clients. In this paper, the authors assume that a service provider has
several servers over which web service operations can be deployed. Given a
workflow of web services and the topology of the servers, the most
efficient mapping of operations to servers must then be discovered.
Efficiency is measured in terms of two cost functions that concern the
execution time of the workflow and the fairness of the load distribution
among the servers. The authors study different topologies for the workflow
structure and the server connectivity and propose a suite of greedy
algorithms for each combination.

RESEARCH NOTE ONE
Matching Attributes Across Overlapping Heterogeneous Data Sources Using
Mutual Information
Huimin Zhao, University of Wisconsin-Milwaukee, USA
Identifying matching attributes across heterogeneous data sources is a
critical and time-consuming step in integrating the data sources. In this
paper, the author proposes a method for matching the most frequently
encountered types of attributes across overlapping heterogeneous data
sources. The author uses mutual information as a unified measure of
dependence on various types of attributes. An example is used to
demonstrate the utility of the proposed method, which is useful in
developing practical attribute matching tools.

RESEARCH NOTE TWO
Disclosure Control of Confidential Data by Applying PAC Learning Theory
Ling He, Saginaw Valley State University, USA
Haldun Aytug, University of Florida, USA
Gary J. Koehler, University of Florida, USA
This paper examines privacy protection in a statistical database from the
perspective of an intruder using learning theory to discover private
information. With the rapid development of information technology, massive
data collection is relatively easier and cheaper than ever before. The
challenge is how to provide database users with reliable and useful data
while protecting the privacy of the confidential information. This paper
discusses how to prevent disclosing the identity of unique records in a
statistical database. The authors’ research extends previous work and
shows how much protection is necessary to prevent an adversary from
discovering confidential data with high probability at small error.
