With the latest technological advancements and the popularization of mobile devices nowadays, software development has evolved towards mobility. One of the main uses of mobile devices is to access social networks. They are becoming important tools in people's life. In this context, the Mingle project has the objective of creating a spontaneous social networks that is mainly accessed by mobile devices,...
A sub-ontology extracted from its base ontology data contains only the concepts and relationships pertaining to the information required by the user. Sub-ontology extraction and sub-ontology tailoring are then viewed as possible solutions to efficiently utilize large-scale ontology data sparsely distributed on a Semantic Grid environment. This shall contribute to reduce the communication overhead...
We present an ontology-based reasoning approach for saving energy in a smart home setting where a mobile phone can serve as a generic sensor which can collect the inhabitant's contextual data. The paper details an ontology that describes the smart home domain and a prototype to test the system. Finally, we conclude with lessons learned from our work in developing an energy-aware smart home prototype...
Peer-to-peer (P2P) data sharing is one of valuable approaches for sharing data among people when they are belonging to different institutions. There are strong demands on both flexible, high-precision search and protection of privacy at peer-to-peer data retrievals. Especially, it is demanded for searching relevant files in P2P environment by using metadata while the terms in metadata that are used...
The paper presents a novel approach to do intelligent mobile searches using semantic, mobile, and cloud computing technologies. A working prototype of a Restaurant Search mobile system is presented for demonstration of the concept. The prototype built is intelligent in understanding and assisting the user choose a restaurant that gives maximum satisfaction to the user under the given constraints.
To efficiently utilize the large-scale ontology data distributed on the Semantic Grid is a problem issue of high concern. Sub-ontology extraction that reflects the user requirements is one method of addressing the issue. Large-scale ontology data can be optimized by extracting the required sub-ontology. In this paper, we construct a Semantic Grid prototype environment to extract the sub-ontology and...
Email addresses, like telephone numbers, are opaque identifiers. They're often hard to remember, and, worse still, they change from time to time. Semantic email addressing (SEA) lets users send email to a semantically specified group of recipients. It provides all of the functionality of static email mailing lists, but because users can maintain their own profiles, they don't need to subscribe, unsubscribe,...
In this paper, we presented an approach for semantic information query based on semantic approximation, where a ranking strategy for answering results is also proposed. We also exploited the implementation technologies related to the approach. Furthermore, a distributed semantic query system called DSQ and experimental results are developed.
Some challenges must be confronted when unstructured information is to be efficiently managed. Firstly, the lifetime process which includes obtaining, analyzing, labeling, saving and applying of unstructured information should be supported. Secondly, the dissimilar and uncertain user's requirements should be fulfilled. And finally the quickly changing enterprise application environments should be...
