- 30 abstract "DBpedia contains millions of untyped entities, either if we consider the native DBpedia ontology, or Yago plus WordNet. Is it possible to automatically classify those entities? Based on previous work on wikilink invariances, we wondered if wikilinks convey a knowledge rich enough for their classification.In this paper we give three contributions. Concerning the DBpedia link structure, we describe some measurements and notice both problems (e.g. the bias that could be induced by the incomplete ontological coverage of the DBpedia ontology), and potentials existing in current type coverage. Concerning classification, we present two techniques that exploit wikilinks, one based on induction from machine learning techniques, and the other on abduction. Finally, we discuss the limited results of classification, which confirmed our fears expressed in the description of general figures from the measurement. We also suggest some new possible approaches to entity classification that could be taken, based on more solid grounds.".

- 31 abstract "Provenance provides vital information for evaluating quality and trustworthiness of information on the Web. To achieve this we must have access to semantically interchangeable provenance information and an agreement on where and how this information to be located. The ongoing W3C Provenance Interchange Working Group provides a promise towards leveraging these problems. In this position paper, we analyze how the upcoming standards could fit together with existing provenance vocabularies and publication approaches so that we achieve the optimal interoperability now and in the near future. Because the standardization is still an ongoing effort, any analysis results presented in this paper are positional and are aimed at communicating the latest development of the working group to the community.".

- 4 sameAs 4.
- 4 abstract "Many Semantic Web applications require the integration of data from distributed and autonomous RDF data sources. However, the values in the RDF triples would be frequently recorded simply as the literal, and additional contextual information such as unit and format is often omitted, relying on consistent understanding of the context. In the wider context of the Web, it is generally not safe to make this assumption. The Context Interchange strategy provides a systematic approach for mediated data access in which semantic conflicts among heterogeneous data sources are automatically detected and reconciled by a context mediator. In this paper, we show that SPARQL queries that involve multiple RDF graphs originating from different contexts can be mediated in the way using the Context Interchange (COIN) Framework.".

- 40 abstract "We describe work-in-progress on the design and methodology of the Dynamic Linked Data Observatory: a framework to monitor Linked Data over an extended period of time. The core goal of our work is to collect frequent, continuous snapshots of a subset of the Web of Data that is interesting for further study and experimentation, with an aim to capture raw data about the dynamics of Linked Data. The resulting corpora will be made openly and continuously available to the Linked Data research community. Herein, we (1) motivate the importance of such a corpus; (2) out- line some of the use-cases and requirements for the resulting snapshots; (3) discuss different “views” of the Web of Data which affect how we define a sample to monitor; (4) detail how we select the scope of the monitoring experiment through sampling, (5) discuss the final design of the monitoring framework which will capture regular snapshots of (subsets of) the Web of Data over the coming months and years.".
