EDF2015 and Linked Data Europe: Big Geospatial Data Workshop

In 2015, the European Data Forum took place in Luxembourg on the 16th and 17th November. GeoKnow team had the pleasure to be present at the event with a booth for showing GeoKnow results. The conference welcomed over 700 participants from industry, research, policy makers, and community initiatives form all over Europe.

The day after the conference we participated at the Linked Data Europe Workshop, that was organized by IQmulus, GeoKnow, LEO and MELODIES teams. Jens Lehmann of the University in Leipzig and Jonas Schulz from Ontos AG demonstrated our GeoKnow workbench, talked about the tools in our Linked Data Stack and had insights into other projects with the scope of Linked Geo Data and Big Data. Overall 10 projects were presented and the workshop ended with an informative discussion about Linked Geo Data tools replacing or extending existing GIS solutions.

Thanks to everyone, who organized the EDF and the workshop.

GeoKnow at Semantics 2015, Vienna

Several partners of GeoKnow were present this year at the Semantics conference 2015.
The previous day of the conference we organised a workshop about the work done during these last three years in GeoKnow.
In the conference, three papers with GeoKnow acknowledgement were presented:

  • Integrating custom index extensions into Virtuoso RDF store for E-Commerce applications, presented by Matthias Wauer,
  • An Optimization Approach for Load Balancing in Parallel Link Discovery presented by Mohamed Ahmed Sherif, and
  • Data Licensing on the Cloud – Empirical Insights and Implications for Linked Dat, presented by Ivan Emilov

And two posters in the posters sessions:

  • The GeoKnow Generator Workbench – An Integrated Tool Supporting the Linked Data Lifecycle for Enterprise Usage, and
  • RDF Editing on the Web

Moreover, the GeoKnow team was demonstrating tools and the Workbench at the Booth reserved for us. It was a nice experience and good opportunity to share our work and to see other peoples projects.


The 2nd Geospatial Linked Data Workshop

This week we the 2nd GeoLD workshop took place previous to the Semantics conference 2015 in Vienna. We had as invited speaker Franz Knibbe from Goedan in Netherlands. Franz is currently contributing to the Spatial Data on the Web Working Group, where people from OGC and W3C are trying to define the best ways to integrate geospatial data on the web of data. His talk was very inspiring, for instance he described us part of the spatial aspects that matter for both working groups, data that goes from gathering data from the galaxy, to microscopical skin structures. You can discover little bit more of his talk in slideshare.
The workshop continued with the presentation of three software tools for exploring geospatial data on the web. Facete is a faceted browser of geospatial data in RDF format, and also allows to edit the data. The second tool was ESTA-LD, which can be used for exploring statistical data that is represented using the Data Cube Vocabulary. And DEER, a data extraction and enrichment framework, allows to create pipelines for analysing unstructured data, finding interlinks with other datasets, and extracting knowledge form the linked datasets in order to enrich the data.
We also presented the GeoKnow Generator demo, which integrates the tools presented +9, offering enterprise ready features, in order to support the company usage of such tools. The usability of GeoKnow tools was demonstrated with two more presentations. The Supply Management showed how they integrated spatial data for improving information and decision making in the supply chain. Finally, the Tourism e-Commerce showed how the integration of geospatial data is used to improve recommendations in a motive-based user request.

2nd edition of GeoLD Workshop at Semantics Conference

We are preparing the second edition of the Geospatial Linked Data Workshop that will be held before the Semantics conference the 15th of September 2015, in Vienna.

For the GeoLD workshop we have invited an active member of the Spatial Data on the Web Working Group, who will be presenting the story so far carried out by this WG. This WG was created a year ago, and brought together two major standards bodies, the Open Geospatial Consortium (OGC) and the W3C with the objective to improve interoperability and integration of spatial data on the Web.

The rest of the presentations at the workshop are about useful tools for exploring geospatial data on the web, and enriching data with geospatial features. These tools and a complete Use Case scenarios will demonstrate the importance of integrating geospatial data to solve business questions.

You can have a detailed agenda in the workshop website. You can register for free in the conference website HERE.

DEER at ESWC 2015

GeoKnow was present at the Extended Semantic Web Conference (which took place in Portoroz, Slovenia) in many ways. In particular, we presented a novel approach for automating RDF dataset transformation and enrichment in the machine learning track of the main conference. The presentation was followed by a constrictive discussion of results and insights plus hints pertaining to further possible applications of the approach.

GeoKnow presented semantic search approach with geospatial context at KNOW@LOD workshop on ESWC

One of the key questions considering the use of linked data is search. Search-driven applications are widely spread, for example in the e-commerce industry or for business information systems. Hence, GeoKnow is also aiming on improving semantic search components, particularly considering geospatial data. Within the GeoKnow consortium the partner Unister — as being active as B2C service provider — is focussing on this topic in the last year of the project.
At the 12th instance of the Extended Semantic Web Conference (ESWC 2015) one result of this research presented in the well-organized 4th Workshop on Knowledge Discovery and Data Mining meets Linked Open Data (KNOW@LOD). The presented paper is named “Computing Geo-Spatial Motives from Linked Data for Search-driven Applications”. Hence, we are considering geo-spatial motives within search queries (e.g., “winter holiday”, “cutural”, “sports activities”) that cannot be answered by a data instance itself but need to interpret the information from the available data to discover relevant regions (e.g., populated places having a sufficient number of cultural hotspots nearby).

Know@LOD 2015 is Over!

The 4th Edition of Know@LOD was held at ESWC 2015 in Portoroz, Slovenia. The workshop was a success, featuring a highly inspiring keynote by Marko Grobelnik, a number of interesting research paper presentation, a very competitive Linked Data Mining Challenge, and a social dinner.

The best paper award goes to Mayank Kejriwal and Daniel P. Miranker: Sorted Neighborhood for Schema-free RDF Data.

The Linked Data Mining Challenge award goes to Suad Aldarra and Emir Muñoz: A Linked Data-Based Decision Tree Classifier to Review Movies.

Congratulations to the winners!

GeoKnow presented paper at WASABI workshop on ESWC

Data-driven processes are the focus of the International Workshop on Semantic Web Enterprise Adoption and Best Practice (WASABI 2015) of the 12th Extended Semantic Web Conference (ESWC 2015). At the 3rd instance of the workshop Andreas Both presented on behalf of the GeoKnow consortium the GeoKnow Generator Workbench which is a key outcome of the our project.
The GeoKnow Generator is a stack of components that covers several steps in the Linked Data Lifecycle. These components have been integrated in the Generator Workbench. To demonstrate its usability we also present four different real world use cases where the Generator and Workbench are used, which are dedicated to the verticals e-commerce, logistics, e-government and automotive industry.

GeoKnow at Belgrade Fair

The GeoKnow project was presented at the recently finished international science and technology fair in Belgrade, Serbia, the largest event of its kind in the region, held from May 11 through 15. The Institute Mihajlo Pupin team used the opportunity to present the goals and accomplishments of the project, as well as PUPIN’s own results, such as GEM, the mobile semantic geospatial browser, and ESTA-LD, the exploratory spatiotemporal analytics tool for Linked Data, both outcomes of the GeoKnow Work Package 4 efforts, to a wider audience.
