In the age of Big Data, filtering mechanisms have to professionalized to increase accessibility to data. This presentation, held at Knowledge Management Academy in Vienna, shows how technologies derived from the Semantic Web can help to establish more efficient means to manage data and information.

2. About Semantic Web CompanyCompany was founded 2001 in Vienna, Austria >20 experts in linked data technologies Product: PoolParty Suite (launched 2009) Serving global 500 companies & large NGOs EU- & US-based consulting services 3. Some customers we serve Pearson Daimler Wolters Kluwer Ministry of Finance (AUT) GBPN Credit Suisse Council of EU Education Services (AUS) World Bank Roche Wood Mackenzie REEEP 4. Agenda Intro Data management the current situation Potential & Benefits of Linked Open Data (LOD) what is metadata, open data, linked data, what is linked open data?Use Cases Global Buildings Performance Network (GBPN) & BPIE World Bank Thesauri EIP on Water: Marketplace Renewable Energy & Energy Efficiency Partnership (REEEP) Q&A 5. Which problems can be solved on top of big data? 6. Common interests. Common topics.Water Management 7. Common vocabulary? Common understanding?Wastewater treatmentWastewater treatmentWater Management 8. Globalisation + Localisation = GlocalisationCertification(Europe)Rating(U.S.) 9. Common data? Questions in common?Energy management policies SearchWater Management 10. The Semantic Puzzle 11. Data Analytics 2.0 The islands are now open for the experts 12. Data management in the environmental sector The current situation Example: Buildings performance 2012 saw the launch of an impressivenumber of online portals sharing data and analysis on energy efficiency in buildings (Ingeborg Nolte, Senior Communication Manager at BPIE) However: how can the value be leveraged of so many (open) data sets which are actually isolated from each other? Will Excel be the ultimate solution? 13. Whats wrong with Open Data? . . . daycare >Seven Dwarfs............... Syntactic heterogenity different trees Semantic heterogenity different tags and attributes (e.g. kindergarten, child_care, daycare) 14. What is metadata, open data or linked data? What is linked open data? 15. MetadataMeta-metadataMetadataData & Information 16.

LOD as a giant knowledge baseWhich policies in the area of renewable energy have helped to initiate projects and programmes in the agricultural sector which finally have improved substantially the nutritional situation in a certain country? 20. Application example #1: Energy Market Intelligence Scenario #1: I am an energy market researcher at the International Energy Agency (IEA). I inform policy makers about the situation in specific renewable energy areas to develop targeted energy support programs. For my research I need indicators about utilisation levels of all alternative forms of energy with regards to geographical and political categories. 21. How does it work? Articles about Renewable Energy 72,018 documents From ~300 web sources Reegle Thesaurus: ~3,000 concepts Traverse hierarchies below main categories (wind, solar, etc.) and classify documents Geonames Annotate documents with regards to their geographical entities DBpedia Lookup several Yago classes to all extracted geographical entities to assert additional categories, e.g.: EUcountries, French-speaking countries etc. 22. How does it work? Semantic SearchGeospatial SearchPoolParty Semantic Integrator.Data Visualisation 23. Application example #2: Health Care Scenario #2: I am an information officer at the Global Health Observatory of the World Health Organisation. I inform policy makers about the global situation in specific disease areas to direct support to the required health support programs. For my research I need data about disease prevalence in relation to socio-economic factors. 24. How does it work? PubMed Articles Cardiovascular Diseases: 39,911 documents Neoplasms: 69,937 documents Nervous System Diseases: 48,128 documents MeSH: 26,700 concepts / 346,600 triples Traverse hierarchies below disease main categories and classify documents Geonames Annotate documents with regards to their geographical entities DBpedia Lookup HDI (The Human Development Index (HDI) is a compositestatistic of life expectancy, education, and income indices used to rank countries into four tiers of human development) 25. How does it work? Semantic SearchGeospatial SearchPoolParty Semantic IntegratorData Visualisation 26. Data management in the environmental sector The current situation Example: Energy data Its necessary to split the responsibility fordifferent data sets between different data providers. (Florian Bauer) However: how can this splitting be co-ordinated and hwo can additional positive network effects be stimulated? 27. 5 stars of data standards Publish Open Data in RDF reusing vocabularies which can be understood and combined by apps in unforeseen ways (e.g. visualization widgets)link your data use URIs to denote things use non-proprietary formats (e.g., CSV instead of Excel) make it available as structured data (e.g., Excel instead of image scan of a table) make your stuff available on the Web (whatever format) under an open license 28. Licensing is key for open data Kind of licenseSource: specified13239%Public Domain6921%Attribution6620%Share alike3510%Closed165%With restrictions52%Other31% 29. Use Cases 30. Global Buildings Performance Network (GBPN) The Global Buildings Performance Network (GBPN) is a globally organised and regionally focused network whose mission is to advance best practice policies that can significantly reduce energy consumption and associated CO2 emissions from buildings. 31. Goals Launch of the GBPN global Knowledge Platform for the Energy Performance of Buildings ( Share Knowledge Build Awareness & showcase best practise Stimulate collective research Stimulate collective analysis from experts worldwide Promote better decision-making Help the building sector effectively reduce its impact on climate change Linked Open Data successfully services these objectives! 32. Technical SolutionIntegrated view (& search index)annotation & mappingpublish enrichGBPN Knowledge Plattform 33. The GBPN Knowledge Plattform LOD based GBPN Terminology GBPN News Aggregator Tool: GBPN Policy Comparative Tool: The GBPN Knowledge Platform is a Linked Open Data project that aims to open and connect with the best resources, data and information on buildings energy performance policies worldwide. Report Database: Laboratory: web blog: 34. The Worldbank Taxonomies & Thesauri 35. EIP on Water - Marketplace 36. reegle country profiles 37. Understanding synonyms & relations? 38. Standardisation and consistency is keyBased on our experience in establishing knowledge broker portals we know: There is a strong need to increase consistency when tagging climate and energy resources We need to ensure the consistency of message being delivered to the public to avoid confusion using terms in different ways This needs standardization of the used categories and tags 39. reegle thesaurus 40. The trusted Clean Energy LOD Cloud 41. reegle tagging a look on using the API is free! 42. users per year (not including datasets reused on other sites) 3,000,000 2,500,000 2,000,000 1,500,000 1,000,000500,000 0 20082009201020112012 43.
