  11. Outline • Introduction • Data Sources • Semantic Web Approach • Future Work

  12. Data Sources

  13. Outline • Introduction • Data Sources • Semantic Web Approach • Future Work

  14. Domain Knowledge Modeling • Core ontology design1 1 http://purl.org/twc/ontology/swqp/core

  15. Domain Knowledge Modeling • Regulation ontology design2 2e.g., http://purl.org/twc/ontology/swqp/region/ny and http://purl.org/twc/ontology/swqp/region/ri; others are listed at http://purl.org/twc/ontology/swqp/region/

  16. Reasoning Domain Data with Regulations • Combining the water measurement data, the core and regulation ontologies, a reasoner can decide if a water body is polluted using OWL2 classification.

  17. Data Integration • We used the open source tool csv2rdf4lod3,4. • Linking ontological terms • Aligning instance references • Converting complex objects 3 Lebo, T., Williams, G.T., 2010. Converting governmental datasets into linked data. Proceedings of the 6th International Conference on Semantic Systems, I-SEMANTICS ’10, pp. 38:1–38:3. 4 http://purl.org/twc/id/software/csv2rdf4lod

  18. Provenance Support • Provenance Capture • Provenance Usage • Data Source Widget • Data Trace Visualization

  19. Water Data Provenance Capture

  20. Water Regulation Provenance Capture See complete table at http://tw.rpi.edu/web/project/TWC-SWQP/compare_five_regulation

  21. Water Regulation Provenance Capture See complete table at http://tw.rpi.edu/web/project/TWC-SWQP/compare_five_regulation

  22. Data Source Widget

  23. Data Source Widget • Usage • Presentation of the data sources on the interface • Source based data retrieval

  24. Provenance Visualization

  25. Future Work • Convert data and encode the regulations for the remaining states • Linking to Health Domain • Utilize data from other sources, e.g. weather and flood forecasts • Apply this architecture to other applications, e.g. the Clean Air Status and Trends demo5 5 http://logd.tw.rpi.edu/demo/clean_air_status_and_trends_-_ozone
