Using Rule-Based Reasoning for RDF Validation
Using Rule-Based Reasoning for RDF Validation Dörthe Arndt, Ben De Meester, Anastasia Dimou, Ruben Verborgh, and Erik Mannens Ghent University - imec - IDLab Sint-Pietersnieuwstraat 41, B-9000 Ghent, Belgium [email protected] Abstract. The success of the Semantic Web highly depends on its in- gredients. If we want to fully realize the vision of a machine-readable Web, it is crucial that Linked Data are actually useful for machines con- suming them. On this background it is not surprising that (Linked) Data validation is an ongoing research topic in the community. However, most approaches so far either do not consider reasoning, and thereby miss the chance of detecting implicit constraint violations, or they base them- selves on a combination of dierent formalisms, eg Description Logics combined with SPARQL. In this paper, we propose using Rule-Based Web Logics for RDF validation focusing on the concepts needed to sup- port the most common validation constraints, such as Scoped Negation As Failure (SNAF), and the predicates dened in the Rule Interchange Format (RIF). We prove the feasibility of the approach by providing an implementation in Notation3 Logic. As such, we show that rule logic can cover both validation and reasoning if it is expressive enough. Keywords: N3, RDF Validation, Rule-Based Reasoning 1 Introduction The amount of publicly available Linked Open Data (LOD) sets is constantly growing1, however, the diversity of the data employed in applications is mostly very limited: only a handful of RDF data is used frequently [27]. One of the reasons for this is that the datasets' quality and consistency varies signicantly, ranging from expensively curated to relatively low quality data [33], and thus need to be validated carefully before use. -

Download a Java Program from the Registry That Uses XSLT to Convert Sensorml files Into KML files
MXC-L071 An SOA Approach to Sensor Services A Major Qualifying Project Report submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fufillment of the requirements for the Degree of Bachelor of Science by Keith Craig and Brett Levasseur Professor Michael J. Ciaraldi, Project Advisor This report represents the work of one or more WPI undergraduate students submitted to the faculty as evidence of completion of a degree requirement. WPI routinely publishes these reports on its web site without editorial or peer review. Abstract The purpose of this project is to demonstrate the use of Semantic Web design and Service Oriented Architecture principles to make sensor information and data readily accessible to clients across the Internet. This project produced a set of XML files that described sensors, defined an ontology that described the vocabulary used in the XML files, and configured an existing registry technology for use within our sensor domain. i Acknowledgements We would like to thank our supervisors Bill Moser and Oliver Newell at Lincoln Laboratory for their invaluable assistance in all facets of this project. We would additionally like to thank Farruk Najmi for his advice regarding ebXML Registries. We would also like to thank Professor Ciaraldi for his help on the WPI side of things.

OGC Sensor Web Enablement
Botts et al. OGC Sensor Web Enablement OGC® Sensor Web Enablement: Overview And High Level Architecture Mike Botts George Percivall Univ. of Alabama in Huntsville Open Geospatial Consortium, Inc. [email protected] [email protected] Carl Reed John Davidson Open Geospatial Consortium, Inc. Image Matters LLC [email protected] [email protected] ABSTRACT A precursor paper (also available as an OGC White Paper) provides a high-level overview of and architecture for the Open Geospatial Consortium (OGC) standards activities that focus on sensors, sensor networks, and a concept called the “Sensor Web”. This OGC focus area is known as Sensor Web Enablement (SWE). For readers interested in greater technical and architecture details, please download and read the OGC SWE Architecture Discussion Paper titled “The OGC Sensor Web Enablement Architecture” (OGC document 06-021r1). Keywords Sensor, OGC, “Sensor Web Enablement”, “sensor web”, transducer, geospatial, “web service”, SOA, “service oriented architecture”, imaging. INTRODUCTION A sensor network is a computer accessible network of many, spatially distributed devices using sensors to monitor conditions at different locations, such as temperature, sound, vibration, pressure, motion or pollutants1. A Sensor Web refers to web accessible sensor networks and archived sensor data that can be discovered and accessed using standard protocols and application program interfaces (APIs).

Within local conservation circles he was primarily known for co-directing, with his partner GSDI Association Board Member Mark Becker Dies of 30 years Lori Charkey, the Bergen Save the Watershed in Tragic Accident Action Network (Bergen SWAN).” The GSDI Association learned of the tragic death of CIESIN Associate Director Mark Becker at the age of 53, on 26 February 2014 in a multi-vehicle accident on the New York State Thruway in Woodbury, NY. Mark was the GSDI Board member representing ‘GSDI Related Global Initiatives’ and was a valued member of the GSDI Outreach and Membership Committee, where his input and insight will be much missed by his colleagues at the Association. Below is an extract from the tribute to Mark from CIESIN. “In his 15 years at CIESIN Mark made contributions that will be felt for a long time. He began his CIESIN career in Mark Becker leading a teacher training workshop for the February 1999, and was soon appointed head of the CHANGE Viewer mapping tool.
