- 48 abstract "The Linking Open Data community project is promoting the creation of interlinked RDF datasets with links between data items identified using dereferenceable URIs. This promising direction for publishing data on the web brings forward a number of issues. A key challenge is to understand the data, the schema, and the interlinks that are actually used both within and across linked datasets. Understanding actual RDF usage is critical in the increasingly common situations where terms from many different RDFS and OWL vocabularies are mixed. In this paper we propose a novel mechanism to describe RDF usage by creating RDF summaries from bisimulation contractions of neighbourhoods (or BCNs). We describe a tool, ExpLOD, that supports constructing and visualizing BCNs, as well as generating SPARQL queries based on the BCNs. We use ExpLOD to describe RDF usage within several of the collections from the Linked Open Data cloud. We present a performance evaluation of graph and SPARQL-based BCN implementations.".

- 8 abstract "Lots of RDF data have been published in the Semantic Web. The RDF data model, together with the decentralized linkage nature of the Semantic Web, brings object link structure to the worldwide scope. Object links are critical to the Semantic Web and the macroscopic properties of object links are helpful for better understanding the current Data Web. In this paper, we propose a notion of object link graph (OLG) in the Semantic Web, and analyze the complex network structure of an OLG constructed from the latest dataset (FC09) collected by Falcons. We find that the OLG has the scale-free nature and the effective diameter of the graph is small compared to its scale. By another experimental result on the last year''s dataset (FC08), we confirm our findings and observe that the object link graph is becoming denser and its diameter is shrinking during the past year, which indicates a good evolution of the Data Web. Finally, we repeat the complex network analysis on the two largest domain-specific subsets of FC09, namely Bio2RDF(FC09) and DBpedia(FC09). The results show that both Bio2RDF(FC09) and DBpedia(FC09) have low density in object links, which has great influence on the density of object links in FC09.".

- 1 abstract "There are several applications that provide access to objects whose descriptions are accompanied by a degree expressing their strength. Such degrees can have various application specific semantics, such as relevance, precision, certainty, trust, etc. In this paper we consider Fuzzy RDF as the representation framework for such "weighted" descriptions, and we propose a novel model for interactively browsing and exploring such sources which allows formulating complex queries by simple clicks. Specifically, and in order to exploit the fuzzy degrees, the model proposes interval-based transition markers. The advantage of the model is that it significantly increases the discrimination power of the interaction, without making it complex for the end user.".
