Marvin : Distributed reasoning over large-scale Semantic Web data

Eyal Oren, Spyros Kotoulas, George Anadiotis, Ronny Siebes, Annette ten Teije, Frank van Harmelen
2009 Journal of Web Semantics  
We present Marvin, a parallel and distributed platform for processing large amounts of RDF data, on a network of loosely-coupled peers.  ...  Many Semantic Web problems are difficult to solve through common divide-and-conquer strategies, since they are hard to partition.  ...  and Semantic Web data [14] .  ...

The Quest for Parallel Reasoning on the Semantic Web [chapter]

Peiqiang Li, Yi Zeng, Spyros Kotoulas, Jacopo Urbani, Ning Zhong
2009 Lecture Notes in Computer Science  
Traditional reasoning tools for the Semantic Web cannot cope with Web scale data. One major direction to improve performance is parallelization.  ...  This article surveys existing studies, basic ideas and mechanisms for parallel reasoning, and introduces three major parallel applications on the Semantic Web: LarKC, MaRVIN, and Reasoning-Hadoop.  ...  Acknowledgements This study was supported by the European Union 7th framework project FP7-215535 LarKC (Large Knowledge Collider) and VU University Amsterdam.  ...

Scalable and Parallel Reasoning in the Semantic Web [chapter]

Jacopo Urbani
2010 Lecture Notes in Computer Science  
A distributed approach is challenging because of the skew in data distribution and the difficulty in partitioning Semantic Web data.  ...  When the amount of data is too large, or the logic is too complex, the computational resources of a single machine are not enough.  ...  Therefore, in order to realize the vision of Semantic Web, a scalable and efficient way to reason over an ever-growing amount of data is crucial.  ...

Semantic Boosting: Enhancing Deep Learning Based LULC Classification

Marvin Mc Mc Cutchan, Alexis J. Comber, Ioannis Giannopoulos, Manuela Canestrini
2021 Remote Sensing  
This paper introduces a methodology which enables the inclusion of geographical object semantics (from vector data) into the LULC classification procedure.  ...  In each experiment CORINE LULC data was used as a ground truth and predicted using imagery from Sentinel-2 and semantics from LinkedGeoData using deep learning.  ...  This includes decisions over imagery (type, scale), how features are represented, choice of training data, and classification algorithm.  ...

Taverna: lessons in creating a workflow environment for the life sciences

Tom Oinn, Mark Greenwood, Matthew Addis, M. Nedim Alpdemir, Justin Ferris, Kevin Glover, Carole Goble, Antoon Goderis, Duncan Hull, Darren Marvin, Peter Li, Phillip Lord (+5 others)
2006 Concurrency and Computation  
The lessons reflect an evolving understanding of life scientists' requirements on a workflow environment, which is relevant to other areas of data intensive and exploratory science.  ...  The in silico experiments undertaken by these research groups can be represented as workflows involving the co-ordinated use of analysis programs and information repositories that may be globally distributed  ...  and many distributed bioinformatics groups that maintain smaller scale databases or analysis tools.  ...

Scaling Out Sound and Complete Reasoning for Conjunctive Queries on OWL Knowledge Bases

Sambhawa Priya
2015 International Semantic Web Conference  
Current large-scale semantic web systems scale to billions of triples but many such systems perform no reasoning or rely on materialization.  ...  One of the challenges the Semantic Web community is facing today is the issue of scalable reasoning that can generate responsive results to complicated queries over large-scale OWL knowledge bases.  ...  Time taken to perform expressive reasoning over semantic web datasets can be vulnerable to the order in which the query clauses are evaluated.  ...

Yan Shvartzshnaider
2010 Lecture Notes in Computer Science  
The GSG adopts approaches and methods from the Semantic Web and thus facilitates a better information sharing abstraction.  ...  It would provide a single abstraction for storing, processing and communicating information based on globally interlinked semantic resources.  ...  The GSG architecture provides support to "anytime" distributed reasoning, similarly to the MARVIN [5] platform.  ...
