I-SEMANTICS 2011: Best Paper Award & Triplification Challenge Winners

This year the I-SEMANTICS conference gave away prices for the best scientific paper and the most promising triplifications.

The best paper award went to Pablo N. Mendes, Max Jakob, Andrés García-Silva and Christian Bizer for their contribution DBpedia Spotlight: Shedding Light on the Web of Documents.

Abstract: The paper impressively shows how Linked Open Data can be utilized  as background knowledge within document-oriented applications such as search and faceted browsing. As a step towards interconnecting the Web of Documents with the Web of Data, the authors developed DBpedia Spotlight, a system for automatically annotating text documents with DBpedia URIs. DBpedia Spotlight allows users to configure the annotations to their specific needs through the DBpedia Ontology and quality measures such as prominence, topical pertinence, contextual ambiguity and disambiguation confidence. They compare their approach with the state of the art in disambiguation, and evaluate their results in light of three baselines and six publicly available annotation systems, demonstrating the competitiveness of the system. DBpedia Spotlight is shared as open source and deployed as a Web Service freely available for public use.

For the 4th time I-SEMANTICS hosted the Triplification Challenge, an event aiming at stimulating the availability of large quantities of RDF data and showcasing practical applications built on top of them. The Challenge consisted of an unspecific “open data track” and a dedicated “open government data track” for which one winner was selected. The prize money of 1000 Euro each was sponsored by Wolters Kluwer Germany.

The “open data track” award went to Daniel Garijo, Boris Villazón and Oscar Corcho for their contribution A Provenance-Aware Linked Data Application for Trip Management and Organization.

Abstract: The authors present El Viajero, an application for exploiting, managing and organizing Linked Data in the domain of news and blogs about travelling. El Viajero makes use of several heterogeneous datasets to help users to plan future trips, and relies on the Open Provenance Model for modeling the provenance information of the resources.

The “open government data track” award went to John Erickson, Yongmei Shi, Li Ding, Eric Rozell, Jin Zheng and Jim Hendler for their contribution TWC International Open Government Dataset Catalog.

Abstract: The TWC International Open Government Dataset Catalog (IOGDC) integrates a diverse selection of more than 70 government dataset catalogs from around the world. IOGDC demonstrates a practical dataset catalog metadata model for integrating diverse dataset catalogs collected from the real world and linking those catalogs into Linked Data Cloud. IOGDC’s faceted browsing and search interface provides a scalable and reconfigurable solution for finding and browsing open government datasets which also offers a compelling demonstration of the value of a common metadata model for open government dataset catalogs. We believe that the vocabulary choices demonstrated by IOGDC highlight the potential for useful Linked Data applications to be created from open government catalogs and will encourage the adoption of such a standard worldwide.

All papers are available in the ACM Digital Library.

We thank all participants for their contributions and wish the winners all the best for their future work!

I-SEMANTICS 2011 – Final Reminder for Extended Submission Deadline


This is the final call for papers for I-SEMANTICS 2011. Due to several requests we decided to extend the deadline of the I-SEMANTICS Conference till Monday, May 30 , 2011.

The new dates are:
Extended Submision Deadline: May 30, 2011
Notification of Acceptance: June 27, 2011
Camera Ready Paper: July 18, 2011

I-SEMANTICS 2011 (www.i-semantics.at) is the 7th conference in the I-SEMANTICS series and takes place from September 7 – 9, 2011 in Graz / Austria. I-SEMANTICS brings together both researchers and practitioners in the areas of Linked Data, Social Software and the Semantic Web in order to present and develop innovative ideas that help realising the “Social Semantic Web” and the “Corporate Semantic Web”.

I-SEMANTICS 2011 will be the host of the 6th AIS SigPrag International Conference on Pragmatic Web as well as the 4th edition of the TRIPLIFICATION Challenge. Further on I-SEMANTICS will be complemented by I-KNOW (www.i-know.at), the 11th International Conference on Knowledge Management. This setup is aiming to reflect the increasing importance and convergence of knowledge management and semantic systems.

The scientific track invites long and short papers along the main topics “Linked Data and Web of Data” to “Semantic Web Applications and Application Building Blocks, Studies, Metrics & Benchmarks”. The papers will be published in the ACM ICPS series. The detailed CfP containing all scientific tracks can be found here: http://i-semantics.tugraz.at/scientific-track/call-for-papers

To address the needs and interests of industry the i-Praxis track invites enterprises and public organisations to present industry relevant solutions in the field of semantic technologies. Presenters will be granted free access to the conference and will have generous time slots to present their applications. The presentations will be published on the conference website. Please find more information here: http://i-semantics.tugraz.at/industry-track/call-for-papers

Which kind of controlled vocabularies matter?

Looking at intermediate results of the Controlled Vocabularies Survey an interesting finding concerns the question which types of knowledge models are currently best fit for actual use in applications.

So far 143 people whose organization already make use of controlled vocabularies answered the question “Which kind of controlled vocabulary do you use or plan to use in your applications?”.
The results so far show that lightweight models like taxonomies and thesauri are somewhat preferred over ontologies:

Taxonomies are the favorite, as 73.6% of participants use or plan to use them, followed by thesauri (62%) and ontologies (61.2%), while simple glossaries lag considerably behind with a usage of 31.4%.

This survey will close in about a week, so please take this chance to make your opinions on this topic count! You can find the questions here, it will take 5-10 minutes to answer them.

All participants will gain access to a report with the results within the following month. The most interesting results will be made public on this blog.

Controlled vocabularies: “Data integration is king”

Just recently a survey about “Controlled vocabularies” and their significance for enterprise information management has started. Until today 143 participants have responded and completed the survey at least partially. To give a first example what was found out, I would like to take a closer at the question: What are the main application areas of controlled vocabularies from your perspective?

A bit surprising is the intermediate result, that it´s not “Semantic Search” or “Support of multilingual applications” which was considered to be the most important application. Instead of this it turned out that “Data Integration” is king:



The bar graph shows the weighed value of each application candidate (1.0 would be a 100% acceptance that this is an important application area of controlled vocabularies). Regarding the top candidate “data integration”

  • 57,4% said “very important”
  • 29,8% “relevant”
  • 7,4% “somewhat relevant”
  • 2,1% “not relevant”
  • 3,2% “Don´t know”

If you don´t think this should be the final result, please help to get a better overview of what´s going on in the controlled vocabulary community. The survey is open until May 18th, 2011 – all participants will gain access to a report with the results within the following month. Most interesting results will be made public on this blog.
