Context-Dependent OWL Reasoning in Sindice - Experiences and Lessons Learnt [chapter]

Renaud Delbru, Giovanni Tummarello, Axel Polleres
2011 Lecture Notes in Computer Science  
In this paper, we report our experiences and lessons learned in building a large scale reasoning engine for Sindice.  ...  The reasoning approach has been deployed, used and improved since 2008 within Sindice and has enabled Sindice to reason over billions of triples.  ...  Conclusions We report our experiences and lessons learned in building a context dependent methodology for large scale web data reasoning.  ...

Solving guesstimation problems using the Semantic Web: Four lessons from an application

Alan Bundy, Gintautas Sasnauskas, Michael Chan
2015 Semantic Web Journal  
We draw on our experience of implementing a semi-automated guesstimation application of the Semantic Web, GORT, to draw four lessons, which we claim are of general applicability. These are: 1.  ...  Curation must be dynamic: Static curation is not only infeasible due to the size and growth rate of the Semantic Web, but curation must be application-specific. 4.  ...  We have illustrated these four lessons by describing the GORT system, which we claim embodies all four of them. We have contrasted it with rival approaches.  ...

Guidelines for multilingual linked data

Asunción Gómez-Pérez, Daniel Vila-Suero, Elena Montiel-Ponsoda, Jorge Gracia, Guadalupe Aguado-de-Cea
2013 Proceedings of the 3rd International Conference on Web Intelligence, Mining and Semantics - WIMS '13  
In this article, we argue that there is a growing number of linked datasets in different natural languages, and that there is a need for guidelines and mechanisms to ensure the quality and organic growth  ...  Whenever possible, we will illustrate and discuss each of these guidelines, methods, and tools on the basis of practical examples that we have encountered in the publication of the datos.bne.es dataset  ...  ACKNOWLEDGMENTS This work has been supported by the BabelData (TIN2010-17550) and myBigData (TIN2010-17060) Spanish projects and by the FP7 European project Monnet (FP7-ICT-4-248458)  ...

Automatic & Semi-Automatic Methods for Supporting Ontology Change

Uta Lösch
2012
Such changes may be predefined in the proposed framework and then be instantiated later on.  ...  Over the last years more and more semantic data has been published on the web. Semantic data is made available in the form of ontologies -formal models of a domain of interest.  ...  Another lesson learned is that RDF graphs have strongly varying characteristics depending on the domain they are describing.  ...

Explaining Data Patterns using Knowledge from the Web of Data

Ilaria Tiddi
2016
In most real world contexts, the interpretation and explanation of the discovered patterns is left to human experts, whose work is to use their background knowledge to analyse, refine and make the patterns  ...  In the last decade, many areas started publishing and sharing their domain-specific knowledge in the form of structured data, with the objective of encouraging information sharing, reuse and discovery.  ...  In the end, it probably took me the same amount of time it took to write the thesis itself.  ...
