Question-Answering (QA) system is improved version of search engines or can be stated as specific Search engines because search engines deliver data in the form of URLs whereas Question-Answering system produces direct answer to the query asked. That's why more focus has been put on developing better Question Answering systems that could respond to large variety of user query. Semantic Web Technology...
Internet plays a vital role in every aspect of our lives. The urge for speed has become a thriving faction when it comes to downloading and the information to be retrieved is not efficient as the web contents are not understandable by computers.GA enabled ontology for platform free dynamic semantic web aims at enhancing the web content with metadata to make it more meaningful. The analysis of the...
Design patterns provide experience reusability and increase quality of object oriented designs. Knowing which design patterns are implemented in a software is important in comprehending, maintaining and refactoring its design. However, despite the interest in using design patterns, traditionally, their usage is not explicitly documented. Therefore, a method is required to reveal this information from...
A digital repository is a digital archive for depositing and providing access to digital contents. It harvests metadata for providing an access framework of digital content to multiple users. In existing systems, query and retrieval is done on centralized basis and do not consider semantics of the query. Since the repositories are distributed, distinct and autonomous, there is a need for a framework...
There is much difference among learners and learning resource providers when the semantic of learning resources is understood and expressed, and it is the important reason which causes lower accuracy in learning resources retrieval. In order to resolve the problem above, three mechanisms are applied as follows: 1) Discipline Ontology is constructed, which is the formalization for concepts and the...
Ever increasing efforts are spent in developing techniques and tools for a full exploitation of semantics in mobile environments, able to overcome volatility and resource limitations of mobile contexts. This paper presents a platform-independent mobile semantic discovery framework as well as a working prototypical implementation which enables advanced knowledge-based services taking into account user's...
Web portals are integration of enterprise applications and services. The further integration of applications in portal context is actually the problem of portlet interoperation. However, there is not yet a definitive answer to portlet interoperation. This paper focuses on using ontology to support portlet semantic interoperability based on new features of JSR268. The proposed approach maps the portlets...
With the development of Semantic Web technology, the Geographic service based on OWL-S is an effective way for sharing and interoperation of heterogeneous information resources in the distributed network environment. This paper focuses on how to dynamic find, bind and invoke Geographic web services by Ontology Web Language for Services (OWL-S). The development of an OWL-S based web service is time...
Ontology is the basis component of the Semantic Web. Since constructing ontologies is a time consuming job for domain experts, many researches are conducted on automatic extraction of ontologies from texts. As the development of folksonomy, more and more researchers have realized that folksonomy is a better knowledge source for constructing ontologies than texts. Although some works have already been...
Success of the Semantic Web depends on mass creation of computer understandable data. Ontology plays more and more important role in creating such semantic data on the Semantic Web. Now there are tools used to generate ontology from legacy database, but it is to some extent difficult for domain expert to understand the meaning between these tools, such as unclear generation approaches, un-unified...
Workflows are becoming an increasingly more common paradigm to manage and control scientific applications. They are an effective technology to define composition of different pieces of knowledge, both in the application domain and in the scientific context. However, workflows are addressed in a number of different perspectives and little consensus has been reached yet on the specification, languages,...
The knowledge requirements of managing emergencies are inherently dynamic and evolving in nature. Existing KM systems in the context of emergency management are essentially static. This paper suggests the use of multi-agent systems for implementation of a more reliable and dynamic emergency planning and response system that can support the evolutionary nature of knowledge in emergencies. To validate...
A new generation of mobile device users is coming of age in the next decade. These users can explore the mobile internet with its new features, services, and applications. Recently, an application platform like the Google's Android mobile platform has revolutionized open applications development for the mobile platform. As increasing number of companies expose their services as web services, enabling...
