Sig.ma

Giovanni Tummarello, Richard Cyganiak, Michele Catasta, Szymon Danielczyk, Renaud Delbru, Stefan Decker
2010 Proceedings of the 19th international conference on World wide web - WWW '10  
We demonstrate Sig.ma 1 , both a service and an end user application to access the Web of Data as an integrated information space.  ...  Sig.ma uses an holistic approach in which large scale semantic web indexing, logic reasoning, data aggregation heuristics, ad hoc ontology consolidation, external services and responsive user interaction  ...  As the user visualizes the aggregate information about the entity, links can be followed to information about related entities. Live views on the Web of Data: rich, embeddable, addressable.  ...

2010 Lecture Notes in Computer Science  
One of the main shortcomings of Semantic Web technologies is that there are few user-friendly ways for displaying, browsing and querying semantic data.  ...  In fact, the lack of effective interfaces for end users significantly hinders further adoption of the Semantic Web.  ...  Visualizations are one of the key components of a Semantic Web portal ( [13] , [14] ).  ...

LESS - Template-Based Syndication and Presentation of Linked Data [chapter]

Sören Auer, Raphael Doehring, Sebastian Dietzold
2010 Lecture Notes in Computer Science  
With LESS we present an end-to-end approach for the syndication and use of linked data based on the definition of templates for linked data resources and SPARQL query results.  ...  In order to improve reliability and performance of linked data, LESS caches versions either for a certain time span or for the case of inaccessibility of the original source.  ...  This work was supported by a grant from the German Federal Ministry of Education and Research (BMBF), provided for the project LE4SW.  ...

Keyword-Driven SPARQL Query Generation Leveraging Background Knowledge

Saeedeh Shekarpour, Soren Auer, Axel-Cyrille Ngonga Ngomo, Daniel Gerber, Sebastian Hellmann, Claus Stadler
2011 2011 IEEE/WIC/ACM International Conferences on Web Intelligence and Intelligent Agent Technology  
The search for information on the Web of Data is becoming increasingly difficult due to its dramatic growth.  ...  So as to simplify and automate the querying and retrieval of information from such sources, we present in this paper a novel approach for constructing SPARQL queries based on user-supplied keywords.  ...  ACKNOWLEDGMENTS We would like to thank our colleagues from AKSW research group for their helpful comments and inspiring discussions during the development of this approach.  ...

Tomasz Tylenda, Mauro Sozio, Gerhard Weikum
2011 Proceedings of the 20th international conference companion on World wide web - WWW '11  
Knowledge bases such as DBpedia or Yago represent the data in a concise and more structured way bearing the potential of bringing database tools to Web Search.  ...  We propose a demonstration of our system which allows the user to specify the entity to summarize, an upper bound on the cost of the resulting summary, as well as to browse the knowledge base in a more  ...  Search engines for structured knowledge (in knowledge bases or gathered from the live Web), such as Entity Cube [3], Google Squared [6], Wolfram Alpha [7], sig.ma [4], or NAGA [8] , tend to either give  ...

Interactive reasoning in uncertain RDF knowledge bases

Timm Meiser, Maximilian Dylla, Martin Theobald
2011 Proceedings of the 20th ACM international conference on Information and knowledge management - CIKM '11  
Recent advances in Web-based information extraction have allowed for the automatic construction of large, semantic knowledge bases, which are typically captured in RDF format.  ...  ) factual knowledge, which makes query answering over this kind of data a challenge.  ...  RELATED WORK State-of-the-art RDF engines (see, e.g., [1, 11] ) primarily focus on conjunctive queries on top of a relational encoding of RDF data.  ...

Will Linked Data Benefit from Inverse Link Traversal?

Stefan Scheglmann, Ansgar Scherp
2014 The Web Conference

2013 Next-Generation Analyst  
This is similar to the capability provided by presently available Internet search engines which enable the retrieval of information on "all" web pages on the Internet.  ...  Due to the steadily increasing data volume, human exploitation of all this sensor data is impossible for effective mission execution.  ...  If one can find the sensors, tap into their data stream, and interpret this sensor data to answer one's questions. This immense pool of data resources will change the way we work and live.  ...
