Mashup refers to an integrated Application Programming Interface (API) that combines data from different data destination or third party sources for web services. This web service provides a combined API that is technologically valid and compatible with other web applications. In recent years, web Mashups have been implemented for solving many issues in existing web applications, such as e-library...
The continuing technological progress indicates a persistent change of communication sequences between actors within service ecosystems. To know these changes and identify the effects on the different services is one of the central challenges to distinguish between desired and malicious communication. Basically, this knowledge is a prerequisite for sustainable ecosystem infrastructures. Today, there...
The concept of ldquoenterprise universityrdquo emerged to denote the new kind of higher education institution that resembles many elements of corporate governance. It has a tighter interaction and integration in the environment, as has to take in account market factors, such as student fee incomes, soft budget allocations for special initiatives, including research funding, risk factors and others...
The Ontology plays a vital role in sharing conceptualizations and terminology interpretable by machines. There are many tools that provide features for Ontology evolution and Ontology maintenance but those tools have limitation on the social involvement perspectives. As results, only a group of Ontology Engineers' point of views has on the Ontology concepts. Thus Semantic Wiki allows people to get...
Most governments, industries and institutions face an adaptive challenge to a changed context for strategy. The new operating environment is characterized by complexity, interactivity, and rapid evolution. It produces more challenges than any one person, business, or government can respond to effectively. This has two implications. The first is the importance of building collaboration that spans industry...
Eco-e-Trading describes the e-business supported trading of environmental contingents between small businesses. Deduced from the already implemented European Emission Trading System (EATS) our research points out potentials to expand the trading to other and smaller operation fields and examines the potential of e-business within such systems. Applying the developed prototype within a case study of...
Global warming is one of the most important and challenging problems being faced this century, capable of triggering a series of events that will have serious consequences on the different ecosystems on planet Earth. In order to manage such consequences, we need dedicated actions for resilience. In such a scenario, the process of adaptation to climate change plays an important part. This is achieved...
The process of business negotiations of complex products or services is an essential binding element in today's dynamic global markets. The digital business ecosystem (DBE) paradigm provides a concept for understanding such dynamic global businesses. However, an analysis form a business model perspective is still missing. This paper presents the case study of an envisioned open source decentralized...
The current Internet infrastructure is becoming each time more heterogeneous regarding computational resources. With the fast improvements in computational capabilities of devices, end-devices are becoming important components for the development of nowadays Internet applications. However, the integration of end-devices into Internet applications is a challenging task due to the intrinsic difficulties...
Wikis, best represented by the popular and highly successful Wikipedia system, have established themselves as important components of a collaboration infrastructure. We suggest that the complex network of user-contributors in volunteer-contributed wikis constitutes a digital ecosystem that bears all the characteristics typical of such systems. This paper presents an analysis supporting this notion...
Knowledge becomes a crucial production factor that is traditionally sourced from individuals and groups within a firm. In a globalised economic world with products and services of growing complexity, firms are challenged to depend on external knowledge. Hence, knowledge becomes an asset that can be exchanged as traditional goods. Currently knowledge exchanges are manufactured on demand. The key question...
In this paper, we present a platform called Knowledge Community (K-Comm) that embodies the principles of a digital ecosystem with collective intelligence. This platform is a knowledge-based social network which allows users to contribute and seek information. Users can ask questions or answer questions asked by other members. K-Comm also captures the user profile, and based on a user's participation,...
In digital ecosystems, where they are no central authorities or single points of failure or control, entities form dynamic relationships to facilitate transactions and knowledge sharing. These relationships are contextual, evolving and not subject to central moderation. The devolved structure of these emergent environments pose unique challenges for identity. In this paper, we build on previous work...
In the last few years artificial immune systems (AISs) have proved their usefulness in several domains, ranging from Intrusion Detection to Information Retrieval. Although their use in several applications, no formal representation has been given yet to AIS concepts and framework. In this paper we propose an architecture for constructing ontologies of artificial immune systems applied to several domains...
This paper proposes a classification approach that incorporates the statistical methods GMM and support vector machines. The proposed GMM-SVM system is presented and experimentally evaluated on text independent speaker identification. Our results prove that the combination approach GMM-SVM is significantly superior than SVM approach. We report improvements of 85,37% amelioration in identification...
When studying digital ecosystems infrastructures we usually consider the peer-to-peer network and the other elements of the service-oriented infrastructure. This paper opens the discussion on DE infrastructures by considering DEs as regional broadband innovations that should both interact with other innovations, like community networks, and be recreated from participatory projects. We therefore overcome...
Highly infectious diseases such as SARS (severe acute respiratory syndrome), Avian influenza (bird flu), small pox, and currently swine flu, to name but a few, pose a significant threat to the global population. Detection and prevention of infectious diseases is notoriously complex and problematic due to the ever increasing number of international travellers. In addition, the risk of being infected...
Structured information (e.g. mathematical information) is one type of Web information. Text-based search engines fall short in retrieving such those information. For example, when a user search for x(y+z) using Google, Google retrieves documents that have xyz, x+y=z, (x+y+z)=xyz or any other document that contains x, y, and/or z but not x(y+z). Google ignores the structure of the expression x(y+z)...
This paper presents a genetic algorithm (GA) to assessment the decision making units (DMU). The Telecommunication sectors based on standards indicators identified by international telecommunication union (ITU) are considered for total assessment by the proposed approach. The indicators are categorized as telephone network size, other services, quality of service, traffic, tariffs, staff, demography,...
Women are underrepresented in the areas of science and engineering, both in academia and industry. This leads to weaker support networks, lower self confidence and lesser access to mentors. We investigate whether a community built with a specific purpose to allow women in science and engineering to share personal stories can support women to reflect and learn from each other's experience. This paper...
