The ``linked data'' approach mandates that resource URIs should be de-referenced to return resource metadata. But for data discovery linkage itself is not enough, and crawling and indexing of data is necessary. Existing Semantic Web search engines are focused on database-like functionality, compromising on index size, query performance and live updates. We present Sindice, a lookup index over resources crawled on the Semantic Web. Our index allows applications to automatically locate documents containing information about a given resource. In addition, we allow resource retrieval through uniquely identifying inverse-functional properties, offer a full-text search and index SPARQL endpoints. Finally we introduce an extension to the sitemap protocol which allows us to efficiently index large Semantic Web datasets with minimal impact on the data providers.Wed Jul 21 16:03:32 CEST 2010WWWconf/www/20101301-1304Sig.ma: live views on the web of data.2010dblp Wed Jul 21 15:58:30 CEST 2010ESWC (2)conf/esws/2010-2225-239Lecture Notes in Computer ScienceHierarchical Link Analysis for Ranking Web Data.60892010dblp Wed Jul 21 15:58:30 CEST 2010ESWC (2)conf/esws/2010-2240-256Lecture Notes in Computer ScienceA Node Indexing Scheme for Web Entity Retrieval.60892010dblp Thu Jun 17 13:10:27 CEST 2010ESWC690-704Lecture Notes in Computer ScienceSemantic Sitemaps: Efficient and Flexible Access to Datasets on the Semantic Web.50212008semantic sitemaps Mon Mar 29 00:29:37 CEST 2010Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember547--560LNCSSindice.com: Weaving the Open Linked Data48252007data linked semantic_web Developers of SemanticWeb applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources. The “linked data” approach, which mandates that resource URIs should be de-referenced and yield metadata about the resource, helps but is only a partial solution and not followed widely. We present a lookup index over resources crawled on the Semantic Web. Our index allows applications to automatically retrieve sources with information about a certain resource. In contrast to more feature-rich Semantic Web search engines, our index is purposely limited in scope and functionality to achieve highly scalability and maintainability.Wed Jan 20 03:00:00 CET 2010IJMSO137-52Sindice.com: a document-oriented lookup index for open linked data.32008LinkedData index search Thu Jan 14 10:59:44 CET 2010IJMSO137-52Sindice.com: a document-oriented lookup index for open linked data.32008semanticweb semanticwebsearchengine sindice Wed Nov 11 00:00:00 CET 2009International Semantic Web Conferenceconf/semweb/2009763-778Lecture Notes in Computer ScienceProduce and Consume Linked Data with Drupal!58232009dblp Tue Nov 03 13:52:23 CET 2009The Semantic Web - ISWC 2009763--778Lecture Notes in Computer ScienceProduce and Consume Linked Data with Drupal!58232009drupal rdfa semanticweb swusage Currently a large number ofWeb sites are driven by Content Management Systems (CMS) which manage textual and multimedia content but also - inherently - carry valuable information about a site’s structure and content model. Exposing this structured information to the Web of Data has so far required considerable expertise in RDF and OWL modelling and additional programming effort. In this paper we tackle one of the most popular CMS: Drupal.We enable site administrators to export their site content model and data to theWeb of Data without requiring extensive knowledge on Semantic Web technologies. Our modules create RDFa annotations and – optionally – a SPARQL endpoint for any Drupal site out of the box. Likewise, we add the means to map the site data to existing ontologies on the Web with a search interface to find commonly used ontology terms. We also allow a Drupal site administrator to include existing RDF data from remote SPARQL endpoints on the Web in the site. When brought together, these features allow networked RDF Drupal sites that reuse and enrich Linked Data. We finally discuss the adoption of our modules and report on a use case in the biomedical field and the current status of its deployment.Thu Oct 01 15:43:34 CEST 2009IJMSO137-52Sindice.com: a document-oriented lookup index for open linked data.32008index lookup semantic Thu Oct 01 15:43:16 CEST 2009The Semantic Web552--565Sindice.com: Weaving the Open Linked Data2008Sindice Developers of Semantic Web applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources.

The particular annotations can differ in expressive power, simplicity, and meaning. We present an elaborate conceptual model for semantic annotations, introduce a unique and rich Wiki syntax for these annotations, and discuss how to best formally represent the augmented Wiki content. We improve existing navigation techniques to automatically construct faceted browsing for semistructured data. By utilising the Wiki annotations we provide greatly enhanced information retrieval. Further we report on our ongoing development of these techniques in our prototype SemperWiki.
