notitio.us - Semantic Information Discovery, Browsing and Sharing
(2007)Searching for information on the Internet became much easier when Google started delivering their service. We got used to getting the most important (probably) results on the top of the list. But more and more ... -
Towards Constraint-Based Composition With Incomplete Service Descriptions
(IEEE, 2007)We apply our work on Web service discovery with initially incomplete information to the problem of service com- position. Rich semantic descriptions of Goals and Web ser- vices allow the unambiguous specification of ... -
The Boardscape: Creating a Super Social Network of Message Boards
(AAAI, 2007)A Web-based message board or forum is an online area where discussions are held by many Internet users on a variety of subjects. More recently, online social networks have been created for various purposes: job searching, ... -
Towards Semantic Interoperability (In-depth comparison of two approaches to solving Semantic Web Service Challenge mediation tasks)
(2007)This paper overviews and compares the DERI and DEI-Cefriel approaches to the SWS-Challenge workshop mediation scenario in terms of the utilized underlying technologies and delivered solutions. In the mediation scenario one ... -
Imprecise Empirical Ontology Refinement: Application to Taxonomy Acquisition
(INSTICC, 2007)The significance of uncertainty representation has become obvious in the Semantic Web community recently. This paper presents new results of our research on uncertainty incorporation into ontologies created automatically ... -
SPARQL++ for mapping between RDF vocabularies
(Springer, 2007)Lightweight ontologies in the formof RDF vocabularies such as SIOC, FOAF, vCard, etc. are increasingly being used and exported by ¿serious¿ applications recently. Such vocabularies, together with query languages like SPARQL ... -
UniStore: Querying a DHT-based Universal Storage
(2007)In recent time, the idea of collecting and combining large public data sets and services became more and more popular. The special characteristics of such systems and the requirements of the participants demand for ... -
Examination of the Impact of Emerging Technologies on eLearning
(Association for the Advancement of Computing in Education, 2007)eLearning has, to date, mostly been a matter of content being displayed on PCs running Windows, Linux, or MAC OS. Emerging technologies have recently, however, expanded the capabilities and scope of portable and mobile ... -
Quantified equilibrium logic and hybrid rules
(Springer, 2007)In the ongoing discussion about combining rules and Ontologies on the Semantic Web a recurring issue is how to combine first-order classical logic with nonmonotonic rule languages. Whereas several modular approaches to de- ... -
Sharing information across community portals with FOAFRealm
(IADIS Press, 2007) -
Towards Optimized Data Fetching for Service Discovery
(IEEE, 2007)The advent of Service Oriented Architecture makes services the most flexible, platform-independent choice for exposing and integrating business functionality across a network. However, the lack of service discovery mechanisms, ... -
Extending Community Ontology Using Automatically Generated Suggestions
(AAAI Press, 2007)In this paper we propose an ontology (formal knowledge base) creation methodology based on integrating external ontologies into the one developed by a community of the do- main experts. We present the MarcOntX agent, a ... -
A Protégé Plug-in Development to Support the NEPOMUK Representational Language
(2007)In this document, we present the challenges faced to develop a plug-in for Protégé that supports requirements for the NEPOMUK1 Representational Language (NRL). NRL is a language built on top of RDF/S and ... -
A DRM Solution Based on Social Networks and Enabling the Idea of Fair Use
(2007)Fair use policy allows legal owners to share products they bought with their acquaintance; it is based on the assumptions that the owners pass an original product and they cannot use it at the same time. In the digital ... -
MultiBeeBrowse Accessible Browsing on Unstructured Metadata
(Springer, 2007)Growing abundance of information on the Internet, especially the Next Generation Internet, poses even more challenges on more efficient information management; hence it has brought attention of the researchers to the faceted ... -
The NEPOMUK Project - On the way to the Social Semantic Desktop
(2007)This paper introduces the NEPOMUK project which aims to create a standard and reference implementation for the Social Semantic Desktop. We outline the requirements and functionalities that were identified for a useful ... -
Semantic SOA to Promote Integration of Heterogeneous B2B Services
(IEEE, 2007)Modeling the semantics of business services and their corresponding messages using ontologies enables flexible integration that is more adaptive to business-driven change. In this paper we demonstrate our approach building ... -
Leveraging Ontologies, Context and Social Networks to Automate Photo Annotation
(Springer, 2007)This paper presents an approach to semi-automate photo an- notation. Instead of using content-recognition techniques this approach leverages context information available at the scene of the photo such as time and location ... -
Handling heterogeneity in RosettaNet messages
(2007)We present a semantic B2B gateway based on the WSMX se- mantic Service-Oriented Architecture to tackle heterogeneities in RosettaNet messages. We develop a rich RosettaNet ontology and use the axiomatised knowledge and ...
