Automatic Semantic Tagging for Drupal CMS launched

REEEP [1] and CTCN [2] have recently launched Climate Tagger, a new tool to automatically scan, label, sort and catalogue datasets and document collections. Climate Tagger now incorporates a Drupal Module for automatic annotation of Drupal content nodes. Climate Tagger addresses knowledge-driven organizations in the climate and development arenas, providing automated functionality to streamline, catalogue and link their Climate Compatible Development data and information resources.

Climate Tagger

Climate Tagger for Drupal is a simple, FREE and easy-to-use way to integrate the well-known Reegle Tagging API [3], originally developed in 2011 with the support of CDKN [4], (now part of the Climate Tagger suite as Climate Tagger API) into any web site based on the Drupal Content Management System [5]. Climate Tagger is backed by the expansive Climate Compatible Development Thesaurus, developed by experts in multiple fields and continuously updated to remain current (explore the thesaurus at http://www.reegle.info/glossary). The thesaurus is available in English, French, Spanish, German and Portuguese. And can connect content on different portals published in these different languages.

Climate Tagger for Drupal can be fine-tuned to individual (and existing) configuration of any Drupal 7 installation by:

  • determining which content types and fields will be automatically tagged
  • scheduling “batch jobs” for automatic updating (also for already existing contents; where the option is available to re-tag all content or only tag with new concepts found via a thesaurus expansion / update)
  • automatically limit and manage volumes of tag results based on individually chosen scoring thresholds
  • blending with manual tagging

“Climate Tagger [6] brings together the semantic power of Semantic Web Company’s PoolParty Semantic Suite [7] with the domain expertise of REEEP and CTCN, resulting in an automatic annotation module for Drupal 7 with an accuracy never seen before” states Martin Kaltenböck, Managing Partner of Semantic Web Company [8], which acts as the technology provider behind the module.

Climate Tagger is the result of a shared commitment to breaking down the ‘information silos’ that exist in the climate compatible development community, and to provide concrete solutions that can be implemented right now, anywhere” said REEEP Director General Martin Hiller. “Together with CTCN and SWC laid the foundations for a system that can be continuously improved and expanded to bring new sectors, systems and organizations into the climate knowledge community.”

For the Open Data and Linked Open Data communities, a Climate Tagger plugin for CKAN [9] has also been published, which was developed by developed by NREL [10] in cooperation with CTCN’s support, harnessing the same taxonomy and expert vetted thesaurus behind the Climate Tagger, helping connect open data to climate compatible content through the simultaneous use of these tools.

REEEP Director General Martin Hiller and CTCN Director Jukka Uosukainen will be talking about Climate Tagger at the COP20 side event hosted by the Climate Knowledge Brokers Group in Lima [11], Peru, on Monday, December 1st at 4:45pm.

Energy Buildings Performance Scenarios as Linked Open Data

The reduction of green house gas emissions is one of the big global challenges for the next decades. (Linked) Open Data on this multi-domain challenge is key for addressing the issues in policy, construction, energy efficiency, production a like. Today – on the World Environment Day 2014 – a new (linked open) data initiative contributes to this effort: GBPN’s Data Endpoint for Building Energy Performance Scenarios.

gbpn-scenariosGBPN (The Global Buildings Performance Network) provides the full data set on a recently made global scenario analysis for saving energy in the building sector worldwide, projected from 2005 to 2050. The multidimensional dataset includes parameters like housing types, building vintages and energy uses  – for various climate zones and regions and is freely available for full use and re-use as open data under CC-BY 3.0 France license.

To explore this easily, the Semantic Web Company has developed an interactive query / filtering tool which allows to create graphs and tables in slicing this multidimensional data cube. Chosen results can be exported as open data in the open formats: RDF and CSV and also queried via a provided SPARQL endpoint (a semantic web based data API). A built-in query-builder makes the use as well as the learning and understanding of SPARQL easy – for advanced users as well as also for non-experts or beginners.

The LOD based information- & data system is part of Semantic Web Companies’ recent Poolparty Semantic Drupal developments and is based on OpenLinks Virtuoso 7 QuadStore holding and calculating ~235 million triples as well as it makes use of the RDF ETL Tool: UnifiedViews as well as D2R Server for RDF conversion. The underlying GBPN ontology runs on PoolParty 4.2 and serves also a powerful domain-specific news aggregator realized with SWC’s sOnr webminer.

reegle.info-trusted-linksTogether with other Energy Efficiency related Linked Open Data Initiatives like REEEP, NREL, BPIE and others, GBPNs recent initative is a contribution towards a broader availability of data supporting action agains global warming – as also Dr. Peter Graham, Executive Director of GBPN emphasized “…data and modelling of building energy use has long been difficult or expensive to access – yet it is critical to policy development and investment in low-energy buildings. With the release of the BEPS open data model, GBPN are providing free access to the world’s best aggregated data analyses on building energy performance.”

The Linked Open Data (LOD) is modelled using the RDF Data Cube Vocabulary (that is a W3C recommendation) including 17 dimensions in the cube. In total there are 235 million triples available in RDF including links to DBpedia and Geonames – linking the indicators: years – climate zones – regions and building types as well as user scenarios….

Why SKOS should be a focal point of your linked data strategy

skos_hand-small

The Simple Knowledge Organization System (SKOS) has become one of the ‘sweet spots’ in the linked data ecosystem in recent years. Especially when semantic web technologies are being adapted for the requirements of enterprises or public administration, SKOS has played a most central role to create knowledge graphs.

In this webinar, key people from the Semantic Web Company will describe why controlled vocabularies based on SKOS play a central role in a linked data strategy, and how SKOS can be enriched by ontologies and linked data to further improve semantic information management.

SKOS unfolds its potential at the intersection of three disciplines and their methods:

  • library sciences: taxonomy and thesaurus management
  • information sciences: knowledge engineering and ontology management
  • computational linguistics: text mining and entity extraction

Linked Data based IT-architectures cover all three aspects and provide means for agile data, information, and knowledge management.

In this webinar, you will learn about the following questions and topics:

  • How SKOS builds the foundation of enterprise knowledge graphs to be enriched by additional vocabularies and ontologies?
  • How can knowledge graphs be used build the backbone of metadata services in organisations?
  • How text mining can be used to create high-quality taxonomies and thesauri?
  • How can knowledge graphs be used for enterprise information integration?

Based on PoolParty Semantic Suite, you will see several live demos of end-user applications based on linked data and of PoolParty’s latest release which provides outstanding facilities for professional linked data management, including taxonomy, thesaurus and ontology management.
