Evaluation of the Technology Agnostic Service Creation Approach

The current computing and communication services provide convenience and functionality. The creation of these services is however not an easy task. Service development is still mainly technical oriented, where service creation tools are meant for serving and assisting the professional developers. In other words, service creation is not seen as a task for end-users. In our research, we wish to enable service creation for the end-users. This is achieved by introducing the technology agnostic approach into the process. In this paper, we present the conceptual architecture as the proposed solution. Prototype tools were designed and implemented as proof of concept. An evaluation event was held to obtain user feedback on the approach and the prototype tools. This paper presents and discusses the outcome of the evaluation

Service Learning in Internet Telephony

Internet telephony can introduce many novel communication services, however, novelty puts learning burden on users. It will be a great help to users if their desired services can be created automatically. We developed an intelligent communication service creation environment which can handle automatic service creation by learning from users' daily communication behaviors. The service creation environment models communication services as decision trees and uses the Incremental Tree Induction (ITI) algorithm for decision tree learning. We use Language for End System Services (LESS) scripts to represent learned results and implemented a simulation environment to verify the learning algorithm. We also noticed that when users get their desired services, they may not be aware of unexpected behaviors that the serivces could introduce, for example, mistakenly rejecting expected calls. In this paper, we also did a comprehensive analysis on communication service fail-safe handling and propose several approaches to create fail-safe services

Value Creation in a QoE Environment

User behavior of multimedia services currently undergoes strong changes. This is reflected in several recent trends, e.g. the increase of rich media content consumption, preferences for more individual and personalized services and the higher sensitivity of end users for quality issues. These changes will eventually lead to strong changes in network traffic characteristics: rising congestion in peak times and less availability of bandwidth for the individual user. As a result, the quality as perceived by the end-user will decrease if network operators and service providers do not anticipate the required changes for the network. Measurable network requirements such as available video and speech quality, security and reliability are addressed by technologies that are commonly summed up in the Quality of Service (QoS) concept. However, the end-users' perception of quality is only reflected in the wider concept of Quality of Experience (QoE). This takes the measurable network requirements into account as well as customer needs, wants and preferences. For the implementation of QoE technologies several network components need to be added or changed resulting in high capital expenditures. Yet, it is not clear if these costs can be compensated with efficiency increases. Thus, new revenue streams for the network operator are necessary to incentivize investments in QoE technologies. In this paper we address four new value creation models that can serve as basis for more elaborated business models for network operators and other actors. We show how interest in QoE of the user, the content provider, the service provider and the advertiser induces new revenue streams. These models are embedded in five possible future QoE scenarios that reveal regulation, end user quality sensibility and end-to-end support as major issues for the future. --Business Models,Quality of Experience (QoE),Quality of Service (QoS),Value Creation

A Survey on Service Creation by End Users

We conducted a survey on end users' willingness and capability to create their desired communication services. The survey is based on the graphical service creation tool we implemented for the Language for End System Services (LESS). We call the tool CUTE, which stands for Columbia University Telecommunication service Editor. This report demonstrates our survey result and shows that relatively inexperienced users are willing and capable to create their desired communication services, and CUTE fits their needs

A visual semantic service browser supporting user-centric service composition

Follow the promising Web 2.0 paradigm, the telecommunications world also wants to implement the Telco 2.0 vision by inviting its users to actively participate in the creating and sharing of services accessible using handheld devices. The EU-IST research project OPUCE (Open Platform for User-Centric Service Creation and Execution) aims at providing end users with an innovative platform which allows an easy creation and delivery of personalized communication and information services. This paper introduces a novel visual semantic service browser built on top of the OPUCE service repository which enables intuitive visualized service exploring and discovery while requires no technical semantic Web knowledge from the user

A User-centric Mobile Service Creation Approach Converging Telco and IT Services

While new competitors are threatening the traditional business models of Telecommunications operators by providing their services directly to the customer, usercentric service creation paradigm brings new opportunities for operators to deliver diverse, attractive, and profitable services directly to the end-user. This paper discusses the service creation model, architecture and implementation in the European Union sponsored research project OPUCE (Open Platform for User-Centric Service Creation and Execution), which aims at enabling end-users to use their smart mobile devices for both creating and consuming personalized services

Reaper – Toward Automating Mobile Cloud Communication

Mobile devices connected to cloud based services are becoming a mainstream method of delivery up-to-date and context aware information to users. Connecting mobile applications to cloud service require significant developer effort. Yet this communication code usually follows certain patterns, varying accordingly to the specific type of data sent and received from the server. By analyzing the causes of theses variations, we can create a system that can automate the code creation for communication from a mobile device to a cloud server. To automate code creation, a general pattern must extracted. This general solution can then be applied to any database configuration. Automating this process frees up valuable development time, allowing developers to make other parts of the application and/or backend service a better experience for the end user

Co-creation of value model for E-service system of Malaysian E-government using hermeneutic phenomenology approach

Malaysian Government has placed high hopes 011 E-Service System (ESS) to facilitate Government to Citizen (G2C). ESS manages the operations in order to enhance a convenient lifestyle and most importantly to attract higher involvement of users. Previous studies have demonstrated remarkable dominant requirement of citizen in ESS context. Furthermore, investigations related to co-creation of ESS for G2C from end-user perspectives have been rarely explored in previous studies. Therefore, it is important to investigate co-creation of ESS for G2C. The aim of this study is to provide insight within the context of co-creation of ESS for G2C to understand the potential determinants that drive successful G2C implementation. This hermeneutic phenomenology case study integrates Co- Creation of Value with Activity Theory as theoretical fundamental in developing the Co-Creation of Value Model (COVA) of ESS for G2C Model. In Phase I, this research describes ESS study to identify common issues, followed with literature review analysis to analyse Co-Creation influences. In Phase II and Phase III, both focus group discussion and expert in depth interviews were conducted which involved twenty four end-users and seven experts of ESS through purposive sampling. Finally, in Phase XV the development of COVA model proceeds with expert validation. The result indicates loyalty and adaptability as enriching experience for end-users meanwhile provider’s value and approach serve as potential value for service provider as source for continual use of the ESS. In addition, the significant value for exchange and learning reduce to 30% of total service failure of ESS on the G2C dimension. Moreover, the Co-Creation factors will complement G2C service success especially in narrowing the gap between human and system
