Semantic Web [1] in the Scientific American, the field has been drawing increasing attention. Data on the Semantic Web is typically represented in RDF. Implementing changes such as adding or deleting an element to a RDF file is difficult. Such changes cannot be executed in an ad hoc manner as they could possibly corrupt the data in the file due to the highly interrelated nature of the RDF statements contained within the file [4]. Sarkar presents five update operations [5], Add, InsertAfter, Delete, Remove, and Replace, which can be applied to an RDF file based on standard database theory and database update operations. This paper investigates the completeness of this set of update operations.

Abstract. An intriguing hypothesis, first suggested by Tim Berners-Lee, is that the structure of online groups should conform to a power law distribution. We relate this hypothesis to earlier work around the Dunbar Number, which is a sup-posed limit to the number of social contacts a user can have

For many, Tim Berners-Lee’s Semantic Web symbolizes the next generation in the evolution of the WWW. Its capability to represent rich information and enable machines to interpret that information may mean that next generation intelligent searching and information filtering services will make our

According to a proposal by Tim Berners-Lee, the World Wide Web should be extended to make a Semantic Web where human understandable content is structured in such a way as to make it machine processable. Central to this conception is the establishment of shared ontologies, which specify
