TL;DR: This paper presents an approach that extracts a graph covering relationships between two objects of interest and shows an interactive visualization of this graph that supports the systematic analysis of the found relationships by providing highlighting, previewing, and filtering features.
Abstract: The Semantic Web has recently seen a rise of large knowledge bases (such as DBpedia) that are freely accessible via SPARQL endpoints. The structured representation of the contained information opens up new possibilities in the way it can be accessed and queried. In this paper, we present an approach that extracts a graph covering relationships between two objects of interest. We show an interactive visualization of this graph that supports the systematic analysis of the found relationships by providing highlighting, previewing, and filtering features.

TL;DR: In this paper, the authors describe an approach to identify, discover, and analyze FOAF documents, analyzing the social networks induced by those FOAF articles and revealing interesting patterns which can become powerful resources for outsourcing and justification of scientific knowledge.
Abstract: Semantic Web researchers have initially focused on the representation, development and use of ontologies but paid less attention to the social and structural relationships involved. The past year has seen a dramatic increase in the amount of published RDF documents using the Friend of a Friend (FOAF) vocabulary, providing a valuable resource for investigating how early Semantic Web adopters use this technology as well as build social networks. We describe an approach to identify, discover, and analyze FOAF documents. Over 1.5 million of FOAF documents are collected to show the variety and scalability of the web of FOAF documents. We analyzed the empirical usage of namespace and properties in the FOAF community, which helps the FOAF project in standardizing vocabularies. We also analyzed the social networks induced by those FOAF documents and revealed interesting patterns which can become powerful resource for outsourcing and justification of scientific knowledge.

TL;DR: This paper describes the proof markup language (PML), an interlingua representation for justifications of results produced by Semantic Web services, and introduces the Inference Web infrastructure that uses PML as the foundation for providing explanations of Web services to end users.

TL;DR: This paper describes a language for ECA rules on XML and a prototype implementation of this language, and describes the architecture of a distributed deployment of such RDF E CA rules.
Abstract: The Semantic Web is based on XML and RDF as its fundamental standards for exchanging and storing information on the World Wide Web Event-condition-action (ECA) rules are a natural candidate for supporting reactive functionality on XML or RDF repositories In this paper we describe a language for ECA rules on XML and a prototype implementation of this language We also discuss some preliminary ideas regarding a language for ECA rules operating on a graph/triple representation of RDF, and we describe the architecture of a distributed deployment of such RDF ECA rules

TL;DR: DAML+OIL's relation with its key ingredients is reviewed, the design decisions and trade-offs that were the basis for the language definition are discussed, and a number of implementation challenges posed by the current language are identified.
Abstract: In the current "Syntactic Web", uninterpreted syntactic constructs are given meaning only by private off-line agreements that are inaccessible to computers. In the Semantic Web vision, this is replaced by a web where both data and its semantic definition are accessible and manipulable by computer software. DAML+OIL is an ontology language specifically designed for this use in the Web; it exploits existing Web standards (XML and RDF), adding the familiar ontological primitives of object oriented and frame based systems, and the formal rigor of a very expressive description logic. The definition of DAML+OIL is now over a year old, and the language has been in fairly widespread use. In this paper, we review DAML+OIL's relation with its key ingredients (XML, RDF, OIL, DAML-ONT, Description Logics), we discuss the design decisions and trade-offs that were the basis for the language definition, and identify a number of implementation challenges posed by the current language. These issues are important for designers of other representation languages for the Semantic Web, be they competitors or successors of DAML+OIL, such as the language currently under definition by W3C.
