The World Wide Web is the source of information available in the structure of interlinked web pages. However, the procedure of extracting significant information with the assistance of search engine is incredibly critical. This is for the reason that web information is written mainly by using natural language, and further available to individual human. Several efforts have been made in semantic similarity...
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...
Semantic Web is extension to World Wide Web. It has different types of applications which need security and privacy. As cyber attacks are increasing day by day, security becomes the critical issue in Semantic Web. In this paper, we have discussed attacks on Semantic Web. We have described the various categories of the attacks like XML attacks, Semantic Web Service attacks, Semantic Web injection attacks,...
Semantic web is an extension of World Wide Web. In Semantic web each resources and services is annotated with the help of web ontology language (OWL). Resource description framework (RDF) represents the web information into its properties and values. Resource description framework schema (RDFS) represents information resources into classes and properties are defined with the help of these classes...
The Semantic web is the extension of WWW, “web of document” that provide a support for “web of data” it gives an easier way to find, share, reuse and combine information. The semantic web can be best known as the web of linked data that enables people to create data stores on the web, build vocabularies, and write rules for handling data. It is based on machine-readable information and builds on XML...
In recent years, semantic search for relevant documents on web has been an important topic of research. Many semantic web search engines have been developed like Ontolook, Swoogle, etc that helps in searching meaningful documents presented on semantic web. The concept of semantic similarity has been widely used in many fields like artificial intelligence, cognitive science, natural language processing,...
Various researchers have recognized that ontology based retrieval is one of the best in terms of precision and recall for semantic search engine. However, they did not specify explicitly any scheme/ algorithm for ontology based indexing and retrieval. This motivates us to conceive a proposal that includes (a) suggesting indexing algorithm to effectively maintain ontologies, (b) suggesting retrieving...
The communication technology is developing in internet to use WWW through wired and wireless networks. The electronic authentication system based on PKI (public key infrastructure) was developed in order to guarantee the stability of client-server type of applications. The efficiency decreases when some of user node becomes mobile terminal, making this capacity, and speeds of internet communication...
