LOD2 Webinar Series: LIMES – Discovery of Links across Knowledge Bases
2012
By Nadine Jaenicke | Category: Events & Conferences, Technology
José Manuel Alonso: “If you want to scale up, you should consider LOD”
2012
By Martin Kaltenböck | Category: Events & Conferences, Partner News
José Manuel Alonso has been working for W3C and CTIC in many open data projects. At the Web Foundation he promotes and supports (linked) open data in developing countries. Martin Kaltenböck from SWC talked with José about ongoing activities in the area of Open Government Data.
Open Data is a powerful worldwide movement these days. Regarding open data projects in developing countries and in high industrialised countries (Europe, US, Australia et al) where do you see the main differences – regarding organisational – cultural – technical issues?
We conducted feasibility studies in Ghana and Chile several months ago, are supporting the Ghana government on the development of its national initiative and have visited and have engaged in Open Data discussions with many other countries in Africa, Latin America and Asia.
The situations are quite diverse and can vary significantly from country to country. It is always difficult to generalize, but I think there are a few important differences that can be highlighted (in no particular order):
- The amount of information available in digital form is generally much lower
- The IT infrastructure is yet to be fully developed or under development
- The capacities on the government and civil society side have to be improved
- The mobile phone is the main device to access information but data connectivity is still scarce, only available in the big cities and not at all in the rural areas
- Digital literacy related issues have to be seriously considered and addressed
- Multilingualism is an important factor, as there are dozens of dialects being spoken in many countries

Linked Open Data: The Essentials – A quick start guide for decision makers
2012
By Andreas Blumauer | Category: Partner News, Use Cases
Linked Open Data: The Essentials provides answers to the following key questions:
- What do the terms Open Data, Open Government Data and Linked Open Data actually mean, and what are the differences between them?
- What do I need to take into account in developing a LOD strategy?
- What does my organisation need to do technically in order to open up and publish its datasets?
- How can I make sure the data is accessible and digestible for others?
- How can I add value to my own data sets by consuming LOD from others?
- What can be learned existing best practices?
- What are the key potentials of sharing and consuming open datasets?

Using WordPress to publish Linked Data
2011
By Andreas Blumauer | Category: Partner News, Technology
- automatic annotation of all blog entries displayed as tooltips
- a comfortable search facility with auto-complete over all concepts from the linked thesaurus including semantic search over the whole blog
- an integrated thesaurus browser, plus
- a corresponding linked data frontend including RDF/XML serialization of the underlying thesaurus + SPARQL endpoint
The improvements of version 2.2.3 compared to older versions in detail:
- Updating the plugin via the wordpress admin interface has been simplified. The plugin now gets the ARC2 triplestore and installs it automatically without need to intervene manually.
- There is a new sidebar-widget which incorporates a search field including autocomplete. This autocomplete service suggests terms from the glossary. Once such a term is chosen, one is automatically connected to the webpage describing the term. The widget can be pulled into any sidebar (depending on the theme) from the sub-section of appearance/widgets.
- There is a new shortcode with which specific parts of the content can be excluded from automatically being linked. The shortcode is called ppt-noparse. Automatic linking is disabled for any text between the code.
- Automatic finding and linking of concepts in running content can be totally disabled under settings. The glossary area is still present and can be reached via the glossary link and the sidebar widget.
The plugin can be downloaded from the WordPress plugin directory. SKOS based vocabularies can be obtained from the vocabulary server of the Semantic Web Company, from the W3C-SKOS Wiki or as another example, for the area of clean energy from reegle-Server.
The plugin is already used by the reegle blog, (reegle is a leading search and data hub in the are of clean energy) or – as another example – by the Semantic Puzzle Blog. For blogs which are specialised on writing about climate change or renewable energy a specialised version of the WordPress linked data plugin can be downloaded and installed.
A comfortable way to generate SKOS thesauri for nearly any domain was recently published: SKOSsy is a tool which extracts controlled vocabularies from DBpedia serving as a “seed thesaurus” for further extensions and enhancements which can be managed with powerful SKOS editors like PoolParty Thesaurus Manager.

Survey result: Controlled Vocabularies Matter!
2011
By Andreas Blumauer | Category: Partner News, Technology
As announced in another blog post a survey was conducted by Semantic Web Company which should find out how controlled vocabularies are perceived and applied by information managers today. Some of the results are covered by a blog post titled “Thesaurus based search engines will become main stream in the near future“, the survey results can be downloaded here.
PoolParty as a provider of standards based tools for
- knowledge organizsation,
- semantic search,
- linked data management,
- knowledge modeling and
- text mining
is pleased with the results because they reveal that industry is heavily interested in open standards like SKOS or RDF and sees the value of linked data based on W3C´s semantic web stack. Here is a short extract of the survey:
Do you think enterprises and other organizations can significantly benefit from using Linked Data?
The answer is a clear YES. A subsequent question also reveals that all kind of organisation sizes have about the same opinion concerning linked data. Only few people think that linked data is a “niche thing”. In general it can be said, that over 90% of the participants think that most or at least some organisations can benefit from using linked data.

Indian-Summer School on Linked Data
2011
By Sören Auer | Category: Events & Conferences, Partner News
ISSLOD takes place in late summer from Sep 12-18, 2011 in Leipzig with hopefully still a lot of Indian Summer (i.e. Altweibersommer / Бабье лето) sunshine rays.
The Linked Data methodology is a light-weight approach to facilitate the transition from the document Web to the Web of Data and ultimately a Semantic Web. With a wide availability of Linked Data tools and knowledge bases, a steadily growing R&D community, industrial applications, the Linked Data paradigm already became crucial building block of the Web architecture.
ISSLOD is primarily intended for postgraduate (PhD or MSc) students, postdocs, and other young researchers investigating aspects related to the Semantic Data Web. The Summer School will also be open to senior researchers wishing to learn about Semantic Web issues related to their own fields of research.
For further details please visit: http://isslod.lod2.eu
ISSLOD is organized by the EU-FP7 project “LOD2 – Creating Knowledge out of Interlinked Data”. Lecturers comprise distinguished experts from LOD2 member organizations as well as invited speakers, the majority of which will – apart from their lectures – also be present for the duration of the school to interact with students. Interaction with senior researchers and establishing contacts within young researchers is a main focus of the school, which will be supported through social activities and an interactive, amicable atmosphere.
- ISSLOD Application Deadline: 30 July 2011
- Notifications: 5 August 2011
- ISSLOD: 12-18 September 2011
There will be a limited number of student grants available. Details of the registration process will be announced on the Web site, after the application deadline. We will keep the registration fee low (175 EUR) and provide reasonable accomodation packages (less than 40 EUR per night) for students.

Florian Bauer: I like to view “linked data” as a “single worldwide API”
2011
By Andreas Blumauer | Category: Partner News, Technology, Use Cases
Florian Bauer is REEEP’s Operations and IT Director, responsible for the overall operational management of the organisation, the product management of reegle (the search engine for renewable energy and energy efficiency) and the management of the IT landscape of REEEP.
PoolParty Team had the chance to talk with Florian about reegle – information gateway on clean energy.
Could you please give us a brief overview over reegle – what are the targets you are pursuing with this platform?
The main aim of the reegle information gateway (http://www.reegle.info) is to provide a one-stop gateway to comprehensive, high-quality and up-to-date information on clean energy. By making this information accessible to stakeholders in the field around the world, and by presenting it in a user-friendly and intuitive format, reegle directly helps to facilitate the transition to low-carbon energy.
The website provides information on renewable energy, energy efficiency and climate change and their various sub-sectors at a global level, and some reegle services actually combine raw data sets from several different sources, put these datasets into context and thus provide enriched information.
reegle is an offshoot of the Renewable Energy & Energy Efficiency Partnership (REEEP), a non-profit, specialist change agent aiming to catalyze the market for renewable energy and energy efficiency, with a primary focus on emerging markets and developing countries.
The new reegle data portal (data.reegle.info), launched in 2011, has established reegle as a publisher and consumer of Linked Open Data in the energy sector. It provides key clean energy datasets free for re-use using Linked Open Data W3C standards.
