One of the basic problems in semantic business management concerns the validation of semantic business processes. This paper introduces the Unary RDF Annotated Petri net systems as a formalism to model and analyze business processes with RDF annotations to deal with semantic information from both

Abstract—We describe existing and anticipated future benefits of an end-to-end methodology for annotating formal RDF statements representing temporal knowledge to be extracted from text, as well as for authoring and validating test and/or application queries to exercise that knowledge. Extraction

The popularization and quick growth of Linked Open Data (LOD) has led to challenging aspects re-garding quality assessment and data exploration of the RDF triples that shape the LOD cloud. Particu-larly, we are interested in the completeness of data and its potential to provide concept definitions

the need for standardization within multimedia metadata. While efforts have been made to link the higher level semantic content to the languages of the semantic web, a big semantic gap remains between the machine extractable metadata (Low Level Descriptors) and meaningful, concise RDF annotations

Annotea is a Web-based shared annotation system based on a general-purpose open RDF infrastructure, where annotations are modeled as a class of metadata. Annotations are viewed as statements made by an author about a Web document. Annotations are external to the documents and can be stored in one

for encoding knowledge on Web pages to make it understandable to electronic agents searching for information. The Defense Advanced Research Projects Agency (DARPA), in conjunction with the W3C, is developing DARPA Agent Markup Language (DAML) by extending RDF with more expressive constructs aimed

There are numerous extensions of RDF that support reasoning about uncertainty, reasoning about pedigree, reasoning about time, and so on. In this paper, we present Annotated RDF (or aRDF for short) in which RDF triples are annotated by members of a partially ordered set (with bottom element

for those major use cases we currently see arising. 1 A Need for RDF Annotations In this paper, we motivate and discuss the syntactic representation and semantic interpretation of generic RDF annotations. In particular, we propose the introduction ofagenericsemanticframeworktorepresent annotations in RDF

set of specific properties, which are needed in the RDF meta model itself, and conventional properties. Finally we show how we use this modified RDF meta model in a structured hypertext system (the KBS Hyperbook System), which uses RDF annotations not only for informational purposes, but also

An information-seeking system is described which combines traditional keyword querying of WWW resources with the ability to browse and query against RDF annotations of those resources. RDF(S) and RDF are used to specify and populate an ontology and the resultant RDF annotations are then indexed
