Ontologies are widely considered as the building blocks of the semantic web, and with them, comes the data interoperability issue. As ontologies are not necessarily always labelled in the same natural language, one way to achieve semantic interoperability is by means of cross-lingual ontology mapping. Translation techniques are often used as an intermediate(More)
Cross-domain management is an increasingly important concern in network management and such management capability is a key-enabler of many emerging computing environments. This paper analyses the requirements for management systems that aim to support flexible and general capability sharing between autonomously managed domains. It introduces a novel Layered(More)
This paper uses simulation studies to explore the behaviour of SCTP congestion control. Several possible variants of SCTP congestion control are identified and each is compared with the behaviour of Reno TCP, a well-known TCP variant. We identify three flaws in the current SCTP congestion control mechanisms. 1. Efficient recovery after a packet loss is only(More)
Regardless of which networking protocols or technologies form the core of the Future Internet it is clear that the environment as a whole will need to support a very broad range of business and user interaction modes. In todays Internet we observe the growing trend for services to be both provided and consumed by loosely coupled value networks of consumers,(More)
Ontologies are at the heart of knowledge management and make use of information that is not only written in English but also in many other natural languages. In order to enable knowledge discovery, sharing and reuse of these multilingual ontologies, it is necessary to support ontology mapping despite natural language barriers. This paper examines the(More)
This paper describes a semi-automated process, framework and tools for harvesting, assessing, improving and maintaining high-quality linked-data. The framework, known as DaCura1, provides dataset curators, who may not be knowledge engineers, with tools to collect and curate evolving linked data datasets that maintain quality over time. The framework(More)
The digital home is both the nexus of a new wave of user-centric service integration and the front line of competition between device vendors, connectivity providers, and added-value service providers. Vertical integration of provider offerings via bundled services and devices is no longer sufficient to satisfy customer demands for best of breed elemental(More)
The Linked Data (LD) Cloud consists of LD sources covering a wide variety of topics. These data sources use formal vocabularies to represent their data and in many cases, they use heterogeneous vocabularies to represent data about the same topics. This data heterogeneity must be overcome to effectively integrate and consume data from the LD Cloud. Mappings(More)
