Summarising and evaluating the contributions made to the Semantic Web investigate atomic number 18a and Challenges of the semantic web - Essay Example turn the progressive implications of the Semantic Web are evident there remains a number of varying contributions and argufys to the overriding movement.Ontologies are angiotensin-converting enzyme of the bad aspects of the Semantic Web. As the Indeed, as the Semantic Web is divided into a number of hierarchical layers, its noted that, the Ontology layer, in form of the OWL Web Ontology Language, is currently the highest layer of sufficient maturity (Lukasiewicz and Straccia 2007). While ontologies are highly contingent elements within the Semantic Web one of the primary problems related to their execution of instrument is the notion of vagueness. Current approaches to vagueness issues have been approached by a variety of formalisms for instance Google uses probalistic techniques. One of the most distributive concerns in terms o f vagueness is the understanding that linguistic elements oftentimes contain within them necessarily vague morphologic demarcations. For instance, Lukasiewicz and Straccia (2007) note the difficulty in determining the true extent that a tomato is ripe one considers that young or tall would produce similar search difficulties. Still, its recognized that considerable breeding is needed in this area, with current research focusing on description logics.Another prominent challenge of the Semantic Web is in terms of uncertainty. While vagueness issues are relegated to linguistic elements that lack a decisive boundary, uncertainty challenges can be understood -- as indicated by Lukasiewicz and Straccia (2007, p. 3) -- as including all those approaches in which statements quite an than being either true or false, are true or false to some luck or possibility (for example, it will rain tomorrow). In these instances, uncertainty is further understood in terms of probability and possibili ty, with possibility regarded as entirely
