GBPN Knowledge Platform using Semantic Technologies and Linked Open Data launched

by , Category: Linked Data & Open Data, Semantic Web Applications, Text Mining

The brand new web based GBPN Knowledge Platform has been launched on 21 February 2013. It helps the building sector effectively reduce its impact on climate change!

It has been designed as a participative knowledge hub and data hub harvesting, sharing and curating best practice policies in building energy performance globally. Available in English and soon in Mandarin, this new web-based tool of the Global Buildings Performance Network (GBPN) aims to stimulate collective research and analysis from experts worldwide to promote better decision-making and help the building sector effectively reduce its impact on climate change. To sustain and accelerate change in the building sector, the GBPN encourages open and transparent access to good quality and verifiable data. The data can be used and re-used in HTML, PDF and machine readable raw data (CSV) formats – provided by a Creative Commons Attribution (CC-BY 3.0 FR) license.

The GBPN Knowledge Platform is built on Drupal CMS and seamless connected with the PoolParty Semantic Information Management Platform of Semantic Web Company. Thereby this knowledge platform makes use of semantic technologies and Linked Open Data (LOD) principles and techniques under the hood. A lot of the available data of the various GBPN tools is provided as (linked) open data under a Creative Commons Attribution license. The Semantic Web Company is responsible for conceptual design and technical implementation of the GBPN Knowledge Platform.

As follows an overview and description of the most important features, tools and services of the information management system.

Quality energy data released: buildingsdata.eu celebrates International Open Data Day

by , Category: Conferences & Events, Linked Data & Open Data

In advance of the 3rd International Open Data Day (http://opendataday.org/) on Saturday 23rd February 2013, BPIE has now made its online knowledge assets “open data ready” by enabling downloads in raw data CSV format, as well as in PDF form.

The comprehensive open data portal presents facts and figures collected in the context of BPIE’s ‘Europe’s Buildings under the Microscope’ study released end of 2011 (see http://bpie.eu/eu_buildings_under_microscope.html). It includes a wide variety of technical data never before collected EU-wide.

The raw data export covers now:

  • 29 European countries
  • 10 building types
  • up to 18 climatic zones per country
  • a total building stock floor area nearly equivalent to the size of Belgium

The Open Data Portal provides data and statistics on:

  • Building stock performance (energy consumption, envelope performance, energy sources);
  • Building stock inventories reflecting floor area, construction year, ownership profile;
  • National policies and regulation;
  • Financial schemes (333 in total).

English: Open Data stickersIn addition, the user can access country fact sheets and definitions.

The data will be improved on an on-going basis and over time, the hub will get enriched with additional topics and information generated through data exchange projects and research partnerships.

BPIE now invites other organisations to add their data to the portal and grow www.buildingsdata.eu into the comprehensive knowledge hub on the energy performance of  Europe’s building stock.

Revealing Trends and Insights in Online Hiring Market Using Linking Open Data Cloud

by , Category: Calls & Competitions, Literature & Publications, LOD2, Semantic Web Applications, Tools & Software

How a business-related application that exploits open-data may look like is presented to the Semantic Web Challenge 2012 by Amar-Djalil Mezaour, Julien Law-To, Robert Isele, Thomas Schandl (SWC) and Gerd Zechmeister (SWC). The paper describes a prototypic linked data application for the Online Hiring Market.

”Active Hiring” is a search based application providing analytics on on-line job posts. This application uses services from the LOD cloud to disambiguate, geotag and interlink data entities acquired from on-line job boards web sites and provides a demonstration of the usefulness of linked open data in business setting.

from Active Hiring a Use Case Study, Paper, 2012

The search based application that combines semantic technologies and services to produce Human Resources (HR) analytics and highlight major trends on online hiring market. So Active Hiring is a demonstration of the benefit of combining open data sets and services with semantic tools as a support technology for increasing the accuracy of business applications. The Active Hiring demonstrator has been developed within the activities of the European project LOD2.

reegle.info – linked (open) energy data cloud

by , Category: Linked Data & Open Data, Semantic Web Applications

Access to the latest high quality information on renewables, energy efficiency and climate change is fundamental to the acceleration of the clean energy marketplace, facilitating investments, promoting new legislation and regulations and broadening interest and knowledge in the sector.

reegle.info acts as a unique clean energy information portal, targeting specific stakeholders including governments, project developers, businesses, financiers, NGOs, academia, international organizations and civil society. Alongside comprehensive country energy profiles, energy statistics and a directory of relevant stakeholders it also offers the clean energy search and an extensive glossary. There is also an insightful clean energy blog with interesting and up-to-date background information.

As reegle.info provides relevant clean energy data from several key energy open data sources as for instance OpenEI, World Bank Data or the UK Open Data Portal the reegle.info Information Gateway has a strong need for efficient and automated data management mechanisms and technologies! Therefore REEEP (The Renewable Energy and Energy Efficiency Partnership) decided to use Linked Open Data (LOD).

Linked Open Data provides a powerful way for reegle.info for sustainable data management and data integration – thereby the current reegle.info linked (open) energy data cloud came into being and looks as follows:

The figure of the reegle.info linked (open) energy data cloud above shows the model behind the scenes of the reegle.info clean energy information gateway providing an insight about sources and respective connections / links between the several sources and data sets.

For the realisation of the Linked Open Data based reegle.info system the following software components are in use:

Going this direction the reegle.info clean energy key portal is very flexible for future expansions in the fields of data integhration and data management by new data sets from several data sources!

By the way – reegle.info is very open too – thereby the whole REEEP generated data is available via a Sparql endpoint for free re-use under the UK Open Government Data license on the reegle.info data portal!

Try it out and make use of free high quality clean energy data!
