TL;DR: YAGO is a large ontology with high coverage and precision, based on a clean logical model with a decidable consistency that allows representing n-ary relations in a natural way while maintaining compatibility with RDFS.

TL;DR: It is shown that many aspects of OWL have been thoroughly reengineered in OWL 2, thus producing a robust platform for future development of the language.

TL;DR: This paper proposes a class of applications called collective knowledge systems, which unlock the ''collective intelligence'' of the Social Web with knowledge representation and reasoning techniques of the Semantic Web.

TL;DR: This paper gives an overview of approaches in this context to managing probabilistic uncertainty, possibilistic Uncertainty, and vagueness in expressive description logics for the Semantic Web.

TL;DR: This paper presents a state-of-the-art of semantic wikis, and introduces SweetWiki, an example of an application reconciling two trends of the future web: a semantically augmented web and a web of social applications where every user is an active provider as well as a consumer of information.

TL;DR: An overview of Falcon-AO: a practical ontology matching system with acceptable to good performance and a number of remarkable features that is one of the best systems in all kinds of tests in the latest three years' OAEI campaigns.

TL;DR: This article discusses putting these together, with linked semantics coupled to linked social networks, to deliver a much greater effect on the power of the Web.

TL;DR: This paper outlines a semantic weblogs scenario that illustrates the potential for combining Web 2.0 and Semantic Web technologies, while highlighting the unresolved issues that impede its realization.

TL;DR: This paper presents the design and implementation of two solutions that combine REST-based design and RDF data access: one solution for integrating existing web services and one server-side solution for creating RDF REST services.

TL;DR: This work presents a new data mining task, the mining of all frequent tri-concepts, together with an efficient algorithm, for discovering implicit shared conceptualizations in social bookmarking tools.

TL;DR: A Semantic Web application for semantic annotation and search in large virtual collections of cultural-heritage objects, indexed with multiple vocabularies, based on established Web standards, in particular HTML/XML, CSS, RDF/OWL, SPARQL and JavaScript.

TL;DR: How SIOC and the Semantic Web can enable linking and reuse scenarios of data from Web 2.0 community sites is described, and a SIOC Types module is introduced to further specify the type of content items and act as a ''glue'' between user posts and the content items created and annotated by users.

TL;DR: It is shown how Semantic Web technologies can be deployed to (partially) solve three important challenges for recommender systems applied in an open Web context to deal with the complexity of various types of relationships for recommendation inferencing.

TL;DR: An overview of the Foafing the Music system, which uses the Friend of a Friend and RDF Site Summary vocabularies for recommending music to a user, depending on the user's musical tastes and listening habits, is given.

TL;DR: IRS-III, a framework for creating and executing semantic Web services, which takes a semantic broker-based approach to mediating between service requesters and service providers is described.

TL;DR: This paper document design decisions made during the implementation of Revyu, discuss the techniques used for linking Revyu data with external sources, and outline how data from the site is being used to infer the trustworthiness of reviewers as sources of information and recommendations.

TL;DR: A mapping approach is developed that embedsSemantic Web data into object-oriented languages and thereby enables reuse of existing Web application frameworks and the usage of ActiveRDF and its integration with the popular Ruby on Rails framework which enables rapid development of Semantic Web applications.

TL;DR: Potluck is a Web user interface that let's casual users-those without programming skills and data modeling expertise-mash up data themselves and lets the user construct rich visualizations of data in-place as the user aligns and cleans up the data.

TL;DR: This effort is complementary to the earlier efforts to represent FMA in OWL and is focused on representing only the information that is explicitly present in the frames representation of the FMA or that can be directly inferred from the semantics of Protégé frames.

TL;DR: Revyu, a reviewing and rating site in the Web2.0 mould that is built on Semantic Web infrastructure and both publishes and consumes linked RDF data affords ease of interaction for regular users and ease of integration with external data sources is presented.

TL;DR: Some potential benefits of Semantic Web techniques in supporting mass-scale, socially-contributed argument tagging are outlined and some recent research in this direction is presented.

TL;DR: It is shown that using the whole web as a corpus for verification yields the best results, but that using a much smaller web corpus can also yield strong performance, and the problem of selecting the best class for each candidate instance that is discovered is considered.

TL;DR: hGRDDL (pronounced ''h-griddle''), a simple mechanism for transforming ad hoc HTML-embedded structured data, such as microformats, into RDFa, is proposed, which preserves the advantages of the original syntax and requires little change on the publisher end.

TL;DR: A model for automatically generating video documentaries that allows viewers to specify the subject and the point of view of the documentary to be generated and an implementation of the model is described in a system, Vox Populi, and applied to an online documentary shot by a group of independent amateur documentarists.

TL;DR: A generic XML Schema to OWL mapping is developed, complemented with an XML to RDF one that allows reusing existing metadata that, once in a semantic space, facilitates data integration, news management and retrieval.

TL;DR: This paper formalizes a syndication architecture that utilizes the Web Ontology Language (OWL) and description logic reasoning for selective content dissemination and investigates incremental query answering for a large subset of OWL and presents an approach to reduce the portion of the ontology that must be considered for query answering in the event of updates.

TL;DR: DBin is a Semantic Web application that enables groups of users with a common interest to cooperatively create semantically structured knowledge bases by creating customized user environments called Brainlets.

TL;DR: A semantic web approach to solve some current limitations of podcasting by adding semantics to the podcast to explain its content, and decomposing it into smaller and meaningful chunks that permits seeking into the inner parts of the file.

TL;DR: It is shown how a quantitative context may be established for what is essentially qualitative in nature by effecting a topological transformation of the lexicon into a metric space where distance is well-defined.
