Target Marketing and Ethics Brand Advertising and Marketing Campaigns
Authors: Fogel Gyongyi K. , Lewis Lorinda F.
Published: February 2011

Marketing to a targeted minority can provide a competitive advantage for an organization. However, there are ethical and legal concerns that must be carefully evaluated. Youth, children, and protected minorities, including women and the elderly, are a high target of advertising because of the increasing importance of these segments in making purchasing decisions. Recent population and demographic factors continue to impact marketing to address minority marketing issues with careful attention to ethics and social responsibility. This paper examines ethical concerns of advertising, the use of animated spokes-characters, marketplace discrimination, misleading practices, ethical concerns in minority marketing, and related advertising regulations. The authors conclude with recommendations for future research and implications for advertising and marketing practice. Policy implications are made for socially responsible advertising and marketing.
Oscillation Damping Enhancement via Coordinated Design of PSS and FACTS-Based Stabilizers in a Multi-Machine Power System Using PSO
Authors: Abido M. A. , Bamasak Saleh M.
Published: February 2011

This paper investigates the enhancement of power system stability via coordinated design of Power System Stabilizers (PSSs), Thyristor Controlled Series Capacitor (TCSC)-based stabilizer, and Static Var Compensator (SVC)-based stabilizer in a multi-machine power system. The design problem of the proposed stabilizers is formulated as an optimization problem. Using the developed linearized power system model, the particle swarm optimization (PSO) algorithm is employed to search for optimal stabilizer settings that maximize the minimum damping ratio of all system oscillating modes. The proposed stabilizers are evaluated on a two-area weakly-connected multi-machine power system with unstable interarea oscillation mode. The nonlinear simulation results and eigenvalue analysis show the effectiveness of the proposed coordinated stabilizers in damping low frequency power system oscillations and enhancing the system stability.
Compensation of Voltage Sags with Phase-Jumps through DVR with Minimum VA Rating Using PSO based ANFIS Controller
Authors: Ramakuru Anil Kumar , Kumar Siva G. , Kumar Kalyan B. , Mishra Mahesh K.
Published: February 2011

Dynamic Voltage Restorer (DVR) restores the distribution system load voltage to a nominal balanced sinusoidal voltage, when the source voltage has distortions, sag/swell and unbalances. DVR has to inject a required amount of Volt-Amperes (VA) into the system to maintain a nominal balanced sinusoidal voltage at the load. Keeping the cost effectiveness of DVR, it is desirable to have a minimum VA rating of the DVR, for a given system without compromising compensation capability. In this regard, a methodology has been proposed in this work to minimize VA rating of DVR. The optimal angle at which DVR voltage has to be injected in series to the line impedance so as to have minimum VA loading on DVR as well as the removal of phase jumps in the three-phases is computed by the Particle Swarm Optimization (PSO) technique. The proposed method is able to compensate voltage sags with phase jumps by keeping the DVR voltage and power ratings minimum, effectively. The proposed PSO methodology together with adaptive neuro–fuzzy inference system used to make the DVR work online with minimum VA loading. The proposed method has been validated through detailed simulation studies.
Beyond Standard Particle Swarm Optimisation
Authors: Clerc Maurice
Published: February 2011

Currently, two very similar versions of PSO are available that could be called “standard”. While it is easy to merge them, their common drawbacks still remain. Therefore, in this paper, the author goes beyond simple merging by suggesting simple yet robust changes and solving a few well-known, common problems, while retaining the classical structure. The results can be proposed to the “swarmer community” as a new standard.
Increasing Spatial Awareness by Integrating Internet Geographic Information Services (GIServices) with Real Time Wireless Mobile GIS Applications
Authors: Tsou Ming-Hsiang , Kim Ick Hoi
Published: February 2011

Spatial awareness is one of the fundamental decision making capabilities for human beings. Two key information technologies, Internet Geographic Information Services (GIServices) and wireless mobile Geographic Information Systems (GIS) can enhance the spatial awareness of decision makers and facilitate more efficient and comprehensive decision making processes. Internet GIServices provide a collaborative communication environment for sharing data, information and knowledge among multiple decision makers and stakeholders. Wireless mobile GIS combines both geospatial information and Global Positional Systems (GPS) coordinates from remotely located field-based personnel to spatial decision support systems (SDSS). By adopting broadband wireless telecommunication technology for connecting Internet GIServices and mobile GIS devices, decision makers can gather near real time information from field personnel and equally quickly distribute updated information back to the field. Communicated via wireless devices and web applications, interactive and dynamic geographic information services will enhance spatial awareness of decision makers, field personnel (such as fire fighters and police officers), and the general public.
My Top 10 Lessons on Lessons Learned Systems
Authors: Liebowitz Jay
Published: February 2011

In view of recent interest in lessons learned information systems, I thought it may be helpful to discuss some lessons learned about lessons learned systems. Part of my knowledge stems from being actively involved in the testing, operations & maintenance, and future development of the agency-wide NASA LLIS (Lessons Learned Information System—now called NASA Engineering Network; http://ildp1.nasa. gov/offices/oce/llis/home/), when I was the Knowledge Management Officer at NASA Goddard.
Mind the Gap
Authors: Tuffley David
Published: February 2011

The application of Socio-Technical theory seeks to improve the alignment between the technical and social sub-systems that comprise organisations. The developers who create the technical systems and the people who use the systems are manifestations of the socio-technical dynamic. Yet a gap exists between these two groups that create a sometimes strong dynamic tension that is a worthy subject for research. Despite many years of study, the User-Developer gap seems as pervasive as ever. This article explores the nature of the gap, and proposes some practical solutions.
Designing for Disaster
Authors: Potts Liza
Published: February 2011

Using the London Bombings of 7 July 2005 as a case study, this paper illustrates the need for sociotechnical interventions in systems design. By employing Actor Network Theory the author makes visible the active participants and technologies within the ecosystems of social software. Such visibility provides insight to the designer seeking to optimize communication systems in the wake of disaster. Guidelines for improving systems and user interfaces based on disaster scenarios are described.
Integrating the Semiotic into UML via Enhancing and Cross-validating Use Case with an Enriched Domain Model
Authors: Oussena Samia , French Tim
Published: February 2011

Use case models are representation of the way in which users of the system interact with it. The UML specification driven approach to system development enable the use case model to be continuously refined and cross-validated from a number of system viewpoints. However, little has been done for validating the model against the organizational and workgroup setting in which the system will reside. This article aims to address this gap by the use of techniques derived from organizational semiotics for validating use case models against a wider aspect of organizational culture and meaning making at the organizational, workgroup and actor level of abstraction. Such approach will enhance the system development by providing “goodness of fit” between system model and organizational values and beliefs.

Knowledge management is increasingly being mentioned in practice and research as a mechanism for gaining competitive advantage. Not only the high-tech industry needs to put knowledge management to use, but also the service industry. This article presents a conceptual framework to provide insights for managers to implement knowledge management in service businesses. Especially, we provide a four-stage approach in this study that was adopted from the processes of knowledge management proposed by Alavi and Leidner (2001) and we suggest two to four strategies for each process.
Commentary
Authors: Ivanov Emil , Liebowitz Jay
Published: February 2011

The primary concern for this commentary is to examine and assess the current state of the research performed in the domain of knowledge flow theory and the relationship between these activities and the ways they are affected within different cultures and generations. We observe little research on the relationship between knowledge flow, cross-cultural factors, and stage of life. We feel that more research is needed in order to deal with cross-cultural generational knowledge flows in organizations.
The Essence of Organizational Knowledge
Authors: Gao Fei
Published: February 2011

The relationships between organizational static substance knowledge with ‘belief’, ‘the true’, ‘true belief’, or ‘justified true belief’ have been outlined briefly in 2003. In this article, through combining new research outcomes, I further explore why different kinds of organizational static substance knowledge can be counted as belief, the true, true belief, or justified true belief. The discussion on the subtle differences between belief, the true, true belief and justified true belief will shed light on our comprehensive and intensive understanding of different kinds of organizational knowledge and will enable managers or chief knowledge officers (CKO) to effectively and efficiently manage knowledge related activities in our knowledge era.
A Framework for Analyzing Online Communities
Authors: Hunter M. Gordon , Stockdale Rosemary
Published: February 2011

This paper examines online communities and describes how they can be differentiated from other Internet supported group interactions. A definition of an online community is given and three generic types are identified. These types are defined by the community models based on the value proposition for the sponsors and members. The value proposition for members is strongly influenced by the model, as facilities and opportunities for interaction are structured by the site sponsors. Where online communities offer fulfillment of specific needs, people participate and become members. Additional benefits enhance the value of membership and encourage retention and greater interactivity. Significant benefits are gained from online communities for businesses, NGOs, other community organizations and individuals. Identifying the different types of communities and their characteristics is an important stage in developing greater understanding of how virtual communities can contribute to businesses, healthcare, community needs and a myriad of other contexts. Examples of the three generic types of online communities are included for further edification.
The War for Talent

Published: February 2011

In current organizations, the importance of knowledge and competence is unquestionable. In Information Technology (IT) companies, which are, by definition, knowledge intensive, this importance is critical. In such organizations, the models of knowledge exploitation include specific processes and elements that drive the production of knowledge aimed at satisfying organizational objectives. However, competence evidence recollection is a highly intensive and time consuming task, which is the key point for this system. SeCEC-IT is a tool based on software artifacts that extracts relevant information using natural language processing techniques. It enables competence evidence detection by deducing competence facts from documents in an automated way. SeCEC-IT includes within its technological components such items as semantic technologies, natural language processing, and human resource communication standards (HR-XML).
Realising Virtual Reality
Authors: McLay Allan
Published: February 2011

This paper addresses the continuing convergence and integration of digital electronic media, and in particular, virtual reality as an exemplar phenomenal media. The author explores and further develops the theme that each of such media entails a specific lexicon or language of use that continually evolves. For this media to be effective, however, it must be widely understood within its community of practice. In this paper, virtual reality is discussed as an exemplar new-media application as a means of virtual representation or reflection of events or behaviours in the real world from a socio-technical perspective.
Hierarchies of Architectures of Collaborative Computational Intelligence
Authors: Pedrycz Witold
Published: February 2011

Computational Intelligence (CI) supports a wealth of methodologies and a plethora of algorithmic developments essential to the construction of intelligent systems. Being faced with inherently distributed data which become evident, the paradigm of CI calls for further enhancements along the line of designing systems that are hierarchical and collaborative in nature. This emerging direction could be referred to as collaborative Computational Intelligence (or C2I for brief). The pervasive phenomenon encountered in architectures of C2I is that collaboration is synonym of knowledge sharing, knowledge reuse and knowledge reconciliation. Knowledge itself comes in different ways: as some structural findings in data and usually formalized in the framework of information granules, locally available models, some action plans, classification schemes, and alike. In such distributed systems sharing data is not feasible given existing technical constraints which are quite often exacerbated by non-technical requirements of privacy or security. In this study, we elaborate on the design of information granules which comes hand in hand with various clustering techniques and fuzzy clustering, in particular.
Semantic Matching, Propagation and Transformation for Composition in Component-Based Systems
Authors: Bouillet Eric , Feblowitz Mark , Liu Zhen , Ranganathan Anand , Riabov Anton
Published: February 2011

Composition of software applications from component parts in response to high-level goals is a long-standing and highly challenging goal. We target the problem of composition in flow-based information processing systems and demonstrate how application composition and component development can be facilitated by the use of semantically described application metadata. The semantic metadata describe both the data flowing through each application and the processing performed in the associated application code. In this paper, we explore some of the key features of the semantic model, including the matching of outputs to input requirements, and the transformation and the propagation of semantic properties by components
On the System Algebra Foundations for Granular Computing
Authors: Wang Yingxu , Zadeh Lotfi A. , Yao Yiyu
Published: February 2011

Granular computing studies a novel approach to computing system modeling and information processing. Although a rich set of work has advanced the understanding of granular computing in dealing with the “to be” and “to have” problems of systems, the “to do” aspect of system modeling and behavioral implementation has been relatively overlooked. On the basis of a recent development in denotational mathematics known as system algebra, this paper presents a system metaphor of granules and explores the theoretical and mathematical foundations of granular computing. An abstract system model of granules is proposed in this paper. Rigorous manipulations of granular systems in computing are modeled by system algebra. The properties of granular systems are analyzed, which helps to explain the magnitudes and complexities of granular systems. Formal representation of granular systems for computing is demonstrated by real-world case studies, where concrete granules and their algebraic operations are explained.
On the Cognitive Complexity of Software and its Quantification and Formal Measurement
Authors: Wang Yingxu
Published: February 2011

The quantification and measurement of functional complexity of software are a persistent problem in software engineering. Measurement models of software complexities have been studied in two facets in computing and software engineering, where the former is machine-oriented in the small; while the latter is humanoriented in the large. The cognitive complexity of software presented in this paper is a new measurement for cross-platform analysis of complexities, functional sizes, and cognition efforts of software code and specifications in the phases of design, implementation, and maintenance in software engineering. This paper reveals that the cognitive complexity of software is a product of its architectural and operational complexities on the basis of deductive semantics. A set of ten Basic Control Structures (BCS’s) are elicited from software architectural and behavioral modeling and specifications. The cognitive weights of the BCS’s are derived and calibrated via a series of psychological experiments. Based on this work, the cognitive complexity of software systems can be rigorously and accurately measured and analyzed. Comparative case studies demonstrate that the cognitive complexity is highly distinguishable for software functional complexity and size measurement in software engineering.
Challenges in the Design of Adoptive, Intelligent and Cognitive Systems
Authors: Kinsner W.
Published: February 2011

Numerous attempts are being made to develop machines that could act not only autonomously, but also in an increasingly intelligent and cognitive manner. Such cognitive machines ought to be aware of their environments which include not only other machines, but also human beings. Such machines ought to understand the meaning of information in more human-like ways by grounding knowledge in the physical world and in the machines’ own goals. The motivation for developing such machines range from self-evidenced practical reasons, such as the expense of computer maintenance, wearable computing in health care, and gaining a better understanding of the cognitive capabilities of the human brain. To achieve such an ambitious goal requires solutions to many problems, ranging from human perception, attention, concept creation, cognition, and consciousness, executive processes guided by emotions and value, and symbiotic conversational human-machine interactions. This paper discusses some of the challenges emerging from this new design paradigm, including systemic problems, design issues, teaching the subjects to undergraduate students in electrical and computer engineering programs, research related to design.
An Enhanced Petri Net Model to Verify and Validate a Neural-Symbolic Hybrid System
Authors: Jorge Ricardo R. , Salgado Gerardo R. , Sánchez Vianey G.C.
Published: February 2011

As the Neural-Symbolic Hybrid Systems (NSHS) gain acceptance, it increases the necessity to guarantee the automatic validation and verification of the knowledge contained in them. In the past, such processes were made manually. In this article, an enhanced Petri net model is presented to the detection and elimination of structural anomalies in the knowledge base of the NSHS. In addition, a reachability model is proposed to evaluate the obtained results of the system versus the expected results by the user. The validation and verification method is divided in two stages: 1) it consists of three phases: rule normalization, rule modeling and rule verification. 2) It consists of three phases: rule modeling, dynamic modeling and evaluation of results. Such method is useful to ensure that the results of a NSHS are correct. Examples are presented to demonstrate the effectiveness of the results obtained with the method.
Application of Artificial Neural Computation in Topex Waveform Data
Authors: Zhang Bo , Schwartz Franklin W. , Tong Daoqin
Published: February 2011

Using the TOPEX radar altimeter for land cover studies has been of great interest due to the TOPEX near global coverage and its consistent availability of waveform data for about one and a half decades from 1992 to 2005. However, the complexity of the TOPEX Sensor Data Records (SDRs) makes the recognition of the radar echoes particularly difficult. In this article, artificial neural computation as one of the most powerful algorithms in pattern recognition is investigated for water ratio assessment over Lake of the Woods area using TOPEX reflected radar signals. Results demonstrate that neural networks have the capability in identifying water proportion from the TOPEX radar information, controlling the predicted errors in a reasonable range.
A General Knowledge Representation Model for the Acquisition of Skills and Concepts
Authors: Ramirez Carlos , Valdes Benjamin
Published: February 2011

A cognitive model for skills and concepts representation as well as a proposal for its computational implementation is presented in this paper. The model is intended to help bridge some of the natural problems that arise in current massive education models through the adaptation and personalization of learning environments. The model is capable of representing rich semantic knowledge, including both skills and concepts, while integrating them through a coherent network of role based associations. The associations build an ontology that integrates on itself different domain taxonomies to represent the knowledge acquired by a student keeping relevant context information. The model is based on a constructivist approach.
Role-Based Autonomic Systems
Authors: Zhu Haibin
Published: February 2011

Autonomic Computing is an emerging computing paradigm used to create computer systems capable of self-management in order to overcome the rapidly growing complexity of computing systems management. To possess self-* properties, there must be mechanisms to support self-awareness, that is an autonomic system should be able to perceive the abnormality of its components. After abnormality is checked, processes of self-healing, self-configuration, self-optimization, and self-protection must be completed to guarantee the system works correctly and continuously. In role-based collaboration (RBC), roles are the major media for interaction, coordination, and collaboration. A role can be used to check if a player behaves well or not. This paper investigates the possibility of using roles and their related mechanisms to diagnose the behavior of agents, and facilitate self-* properties of a system.
Combining Ontology with Intelligent Agent to Provide Negotiation Service
Authors: Pu Qiumei , Cao Yongcun , Pan Xiuqin , Fu Siyao , Hou Zengguang
Published: February 2011

Agent and Ontology are distinct technologies that arose independent of each other, having their own standards and specifications. The semantics web is one of the popular research areas these days, and is based on the current Web, which adds more semantics to it for the purpose of building the Ontology of Web content. In this regard, application program on Web can make the purpose of cross-platform calculation come true by taking advantage of Ontology. However, agent is a theory able to enhance abstraction of software itself, and as it is know, negotiation protocol is the basic principle in the electronic commerce which has a direct impact on the efficiency of the negotiation. This study examines the communication architecture with negotiation protocol on the Semantic Web. Precisely speaking, agents make computing with Ontology, and the authors define an agent’s communication ontology for this communication framework and semantic web use Ontology to describe the negotiation protocol. In this context, the buyer or seller will be able to improve semantic cognitive in process of negotiation. Also, it can provide an intelligent platform for the information exchange on the same understanding about the content of communication in the electronic negotiation service.

Published: February 2011

Integrating products and services to customized solutions can help firms differentiate from their competitors. In practice, however, various companies fall short in extracting value from their customers. Therefore, this paper focuses on pricing aspects as central means for value appropriation in the context of solutions. Following the resource-based view of the firm, the authors adopt a process-oriented perspective on pricing practices in order to identify crucial factors and activities. Based on 15 in-depth interviews with practitioners from various industries, this paper derives six steps of a price management process for value appropriation in the context of solution selling and presents critical activities and routines within each step.
An Ideation Framework for Service Process Improvement
Authors: Kaner Maya , Karni Reuven
Published: February 2011

Service delivery processes play a key role in the competitiveness of modern organizations. Their effectiveness and efficiency are a consequence of successful design of new processes and improvement of existing processes. Improvement methodologies commonly focus on generic steps serving as a road map for moving a process from its current state along a guided path to better performance. However, these methodologies ignore the crucial step of methods for modifying processes, which often necessitate the generation of new improvement alternatives; generally based on “randomized” brainstorming rather than on systematic triggering of new ideas and reusing past improvements. The authors’ framework comprises and integrates 21 goal determinants to be achieved through process redesign, 32 best practices describing possible process modifications, 40 TRIZ inventive principles for generating new improvement ideas, and case-based reasoning (CBR) for retaining and reusing past improvements. This paper illustrates the application of the proposed methodology using an example of an inbound telesales process.
Preliminary Discussions on Several Characteristics of Service Value
Authors: Ma Chao , Wang Zhongjie , Xu Xiaofei
Published: February 2011

Service is defined as a provider-to-client co-production that creates and captures value while sharing risks. Value plays a central position in the lifecycle of services, for example, new values are defined in service mode, designing service models to support the proposed values, and developing service systems to deliver values to customers and providers. It is also necessary to make clear what kinds of characteristics service value has. In this paper, the authors make a classification on service values and discuss characteristics of service value, that is, transitivity, decomposability, partition, transformation, and dependency. The authors illuminate these characteristics by presenting several practical examples, as well as introducing value-aware service engineering and methodology (VASEM). Results of this paper will provide references to value-oriented service innovation, service design and service system development in SSME domain.
An Integrated Methodology for the Evaluation of Electronic Port Services
Authors: Marianos Nikolaos , Lambrou Maria
Published: February 2011

This article introduces a formal evaluation methodology for IT investments specifically designed to cope with the needs of port industry. Port industry is a service-oriented industry and, as such, is characterised by the intangible nature of benefits. The goal of this paper is to develop a methodology for the evaluation of container terminal related electronic services that incorporates both strategic and analytic evaluation techniques for performing both ex-ante and ex-post evaluation. Port industry is an interesting case because, although it is characterised by intense competition and ports have to concentrate in satisfying the customers’ needs by proving value added services with the use of advanced information and communication technologies (ICT), it is also characterised by a lag in adopting new technologies and techniques compared to other industries. In this paper, the authors present an analysis of the industry’s specific needs and proposes a dynamic evaluation methodology specifically designed to satisfy them.
Using System Dynamics to Analyze Customer Experience Design
Authors: Hsieh Yen-Hao , Yuan Soe-Tsyr
Published: February 2011

Today, customer experience design is an emerging research direction in the experience economy where good customer experiences can lead service providers to achieve their business goals. Customer expectation, another key point for designing service experiences, affects how customers really feel during service experience delivery, while service operation is another important factor must be taken into account. System dynamics, as an analytic tool, can provide designers with a different way of thinking by integrating these factors for customer experience design. Accordingly, this study not only models the process of customer experience design by using causal loop diagrams and stock and flow diagrams, but also analyzes how the feedback and time delay factors influence customer experience design based on the simulation results of system dynamics. According to the macro viewpoint of system dynamics, this paper analyzes these important factors within customer experience design.
A Structured Test Approach for Service Concepts

Published: February 2011

To assure new services attain a certain level of quality, services should be developed and tested systematically like products or software. In practice, this is rarely the case, especially in regards to the testing of service concepts due to appropriate solutions, processes, and methodology seem to be missing. In this paper, the authors propose an approach to how service testing can be realized in practice and present supporting processes, methods, and technologies for testing services in laboratory environments.

Authors: Pekkarinen Satu , Melkas Helinä
Published: February 2011

This paper examines an assistive technology targeted to ageing people: a safety alarm and the related service system. A safety alarm is not only a technical device; with the related system, it can be seen as a holistic opportunity for innovation. The operation of safety alarm systems and services depends on many critical points. Potholes lying in safety alarm systems are identified in this study, taking into account the technology, services and organizational network. The potholes are studied as sources and opportunities for potential innovation. Service, social, organizational, process and marketing innovations—combined with technology—are significant parts of innovation activity related to the ageing population. A technical device is not used in a vacuum: there is also organization and service acts, as well as the user with her or his values, appreciations, state of health, and so forth. These factors impact the variety of innovation potential in assistive technology. This paper examines the existing technology and related services as well as various innovation opportunities related to uncovering their shortcomings.
ODACE SLA

Published: February 2011

The establishment of Service Level Agreements between service providers and clients remains a complex task regarding the uninterrupted growth of the IT market. In fact, it is important to ensure a clear and fair establishment of these SLAs especially when providers and clients do not share the same technical knowledge. To address this problem, the authors started modeling client intentions and provider offers using ontologies. These models helped them in establishing and implementing a complete semantic matching approach containing four main steps. The first step consists of generating correspondences between the client and the provider terms by assigning certainties for their equivalence. The second step corrects and refines these certainties. In the third step, the authors evaluate the matching results using inference rules, and in the fourth step, a draft version of a Service Level Agreement is automatically generated in case of compatibility.
Execution Management for Mobile Service-Oriented Environments
Authors: Konstanteli Kleopatra G. , Kirkham Tom , Gallop Julian , Matthews Brian , Johnson Ian , Kardara Magdalini , Varvarigou Theodora
Published: February 2011

This paper presents an Execution Management System (EMS) for Grid services that builds on the Open Grid Services Architecture (OGSA) while achieving “mobile awareness” by establishing a WS-Notification mechanism with mobile network session middleware. It builds heavily on the Session Initiation Protocol (SIP), used for managing sessions with mobile terminals (such as laptops and PDAs) where the services are running. Although the management of mobile services is different to that of ubiquitous services, the enhanced EMS manages both of them in a seamless fashion and incorporates all resources into one Mobile Dynamic Virtual Organization (MDVO). The described EMS has been implemented within the framework of the Akogrimo EU IST project and has been used to support mission critical application scenarios in public demonstrations, including composite and distributed applications made of both ubiquitous and mobile services within multiple domains.
A Method to Support Fault Tolerance Design in Service Oriented Computing Systems
Authors: Cotroneo Domenico , Pecchia Antonio , Pietrantuono Roberto , Russo Stefano
Published: February 2011

Service Oriented Computing relies on the integration of heterogeneous software technologies and infrastructures that provide developers with a common ground for composing services and producing applications flexibly. However, this approach eases software development but makes dependability a big challenge. Integrating such diverse software items raise issues that traditional testing is not able to exhaustively cope with. In this context, tolerating faults, rather than attempt to detect them solely by testing, is a more suitable solution. This paper proposes a method to support a tailored design of fault tolerance actions for the system being developed. This paper describes system failure behavior through an extensive fault injection campaign to figure out its criticalities and adopt the most appropriate countermeasures to tolerate operational faults. The proposed method is applied to two distinct SOC-enabling technologies. Results show how the achieved findings allow designers to understand the system failure behavior and plan fault tolerance.
Investigating the Role of Service Encounter in Enhancing Customer Satisfaction
Authors: Chen Irene
Published: February 2011

Recently, it is found that several pure e-tailers set up a customer service center where on-line shoppers can access a real person over the phone to answer their questions. However, there has been little systematic research examining how service encounter help to enhance customer satisfaction when a pure e-retail company set up a call center to provide additional services. This study conducted a questionnaire survey and collected data from persons who shopped on-line and had experiences in requesting help from customer service centers. 116 responses were collected and the data were then analyzed to examine the four relationships posited in the research model. The proposed research model suggests that service encounter significantly influences service quality and information quality, which can jointly predict customer satisfaction. Findings of this study help to advance the understanding of the role that service encounters play in enhancing customer satisfaction.

Published: February 2011

Traditional Internet is commonly wired with machine to machine persistent connections. Evolving towards mobile and wireless pervasive networks, Internet has to entertain dynamic, transient, and changing interconnections. The vision of the Internet of Things furthers technology development by creating an interactive environment where smart objects are connected and can sense and react to the environment. Adopting such an innovative technology often requires extensive intelligence research. A major value indicator is how the potentials of RFID can translate into actions to improve business operational efficiency (Luo et al., 2008). In this paper, the authors will introduce a local association network with a coordinated P2P message delivery mechanism to develop Internet of Things based solutions body parts tagging and tracking. On site testing and performance evaluation validate the proposed approach. User feedback strengthens the belief that the proposed approach would help facilitate the technology adoption in body parts tagging and tracking.

Authors: Chebotko Artem , Deng Yu , Lu Shiyong , Fotouhi Farshad , Aristar Anthony
Published: February 2011

The development of the Semantic Web, the next-generation Web, greatly relies on the availability of ontologies and powerful annotation tools. However, there is a lack of ontology-based annotation tools for linguistic multimedia data. Existing tools either lack ontology support or provide limited support for multimedia. To fill the gap, we present an ontology-based linguistic multimedia annotation tool, OntoELAN, which features: (1) the support for OWL ontologies; (2) the management of language profiles, which allow the user to choose a subset of ontological terms for annotation; (3) the management of ontological tiers, which can be annotated with language profile terms and, therefore, corresponding ontological terms; and (4) storing OntoELAN annotation documents in XML format based on multimedia and domain ontologies. To our best knowledge, OntoELAN is the first audio/video annotation tool in the linguistic domain that provides support for ontology-based annotation. It is expected that the availability of such a tool will greatly facilitate the creation of linguistic multimedia repositories as islands of the Semantic Web of language engineering.
A Layered Model for Building Ontology Translation Systems
Authors: Corcho Oscar , Gomez-Perez Asunción
Published: February 2011

In this paper we present a model for building ontology translation systems between ontology languages and/or ontology tools, where translation decisions are defined at four different layers: lexical, syntax, semantic, and pragmatic. This layered approach provides a major contribution to the current state of the art in ontology translation, since it makes ontology translation systems easier to build and understand and, consequently, to maintain and reuse. As part of this model, we propose a method that guides in the process of developing ontology translation systems according to this approach. The method identifies four main activities: feasibility study, analysis of source, and target formats, design, and implementation of the translation system, with their decomposition in tasks, and recommends the techniques to be used inside each of them.
A Survey on Ontology Creation Methodologies
Authors: Cristani Matteo , Cuel Roberta
Published: February 2011

In the current literature of knowledge management and artificial intelligence, several different approaches to the problem have been carried out of developing domain ontologies from scratch. All these approaches deal fundamentally with three problems: (1) providing a collection of general terms describing classes and relations to be employed in the description of the domain itself; (2) organizing the terms into a taxonomy of the classes by the ISA relation; and (3) expressing in an explicit way the constraints that make the ISA pairs meaningful. Though a number of such approaches can be found, no systematic analysis of them exists which can be used to understand the inspiring motivation, the applicability context, and the structure of the approaches. In this paper, we provide a framework for analyzing the existing methodologies that compares them to a set of general criteria. In particular, we obtain a classification based upon the direction of ontology construction; bottom-up are those methodologies that start with some descriptions of the domain and obtain a classification, while top-down ones start with an abstract view of the domain itself, which is given a priori. The resulting classification is useful not only for theoretical purposes but also in the practice of deployment of ontologies in Information Systems, since it provides a framework for choosing the right methodology to be applied in the specific context, depending also on the needs of the application itself.
Archetype-Based Semantic Interoperability of Web Service Messages in the Health Care Domain

In this article, we describe an infrastructure enabling archetype-based semantic interoperability of Web Service messages exchanged in the health care domain. We annotate the Web Service messages with the OWL representation of the archetypes. Then, by providing the ontology mapping between the archetypes, we show that the interoperability of the Web Service message instances can be achieved automatically. An OWL mapping tool, called OWLmt, has been developed for this purpose. OWLmt uses OWL-QL engine, which enables the mapping tool to reason over the source archetype instances while generating the target archetype instances according to the mapping patterns defined through a GUI.
A Distributed Patient Identification Protocol Based on Control Numbers with Semantic Annotation
Authors: Eichelberg Marco , Aden Thomas , Thoben Wilfried
Published: February 2011

One important problem of information systems in health care is the localisation and access to electronic patient records across health care institute boundaries, especially in an international setting. The complexity of the problem is increased by the absence of a globally accepted standard for electronic health care records, the absence of unique patient identifiers in most countries, and the strict data protection requirements that apply to clinical documents. This article describes a protocol that allows the identification of locations of patient records for a given patient and provides access to these records, if granted, under consideration of the legal and technical requirements. The protocol combines cryptographic techniques with semantic annotation and mediation and presents a simple Web-service-based access to clinical documents.
Family History Information Exchange Services Using HL7 Clinical Genomics Standard Specifications
Authors: Shabo Amnon , Hughes Kevin S.
Published: February 2011

A number of family history applications are in use by health care professionals (e.g., CAGENE, Progeny, Partners Health care Family History Program) as well as by patients (e.g., the US Surgeon General’s Family History Program). Each has its own proprietary data format for pedigree drawing and for the maintenance of family history health information. Interoperability between applications is essentially non-existent. To date, disparate family history applications cannot easily exchange patient information. The receiving application should be able to understand the semantics of the incoming family history and enable the user to view and/or to edit it using the receiving applications interface. We envision that any family history application will be able to send and receive an individual’s family history information using the newly created HL7 Clinical Genomics Specifications through the Semantic Web, using services that will transform one format to the other through the HL7 canonical representation.
