Title: Comparing OSM Area-Boundary Data to DBpedia

Authors: Doris Silbernagl, Nikolaus Krismer and Günther Specht (Department of Computer Science, University of Innsbruck, Austria)

Abstract: OpenStreetMap (OSM) is a well known and widely used data source for geographic data. This kind of data can also be found in Wikipedia in the form of geographic locations, such as cities or countries. Next to the geographic coordinates, also statistical data about the area of these elements can be present. Since it is possible to extract these data from OpenStreetMap as well, it is sensible to examine the quality of the OSM information about those specific boundary elements and compare them to an also crowd-sourced source like Wikipedia. Hence, in this paper OSM data of different countries are used to calculate the area of valid boundary (multi) polygons and are then compared to the respective DBpedia (a large scale knowledge base extract from Wikipedia) entries.

XML Documents in MediaWiki

Title: XML Documents in MediaWiki

Authors: Johannes Nanninga (University of Duisburg-Essen), Benjamin Weyers (RWTH Aachen), Wolfram Luther (University of Duisburg-Essen)

Abstract: Wikis allow for the collaborative creation and management of a wide variety of informal data. However, certain use cases require collaborative creation of formal, structured documents. XML and related technologies can be used to specify document formats but have so far not been comprehensively incorporated into Wikis. We present an extension for the MediaWiki software that enables it to create, store, validate and transform XML documents, schemas, and style sheets. The extension’s applicability is shown by the example of a use case on a wiki for the creation of XML-based user interaction patterns.

Title: The Social Shaping of Open Data through Administrative Processes

Authors: Sirko Hunnius (IfG.CC), Bernhard Krieger (IfG.CC)

Abstract: Many models have been provided in the last years that aim at describing an optimal open data publication process. However, they fail to explain the different outcomes of open data initiatives. Based on qualitative research this paper conceptualises the open data phenomenon as a set of techno-political arenas in which different interests of a variety of actors potentially and actually collide. The micro-political arena model constitutes an instrument to delineate the social and institutional context of open data that can be employed to explain the successes, as well as the failures of individual open data projects.

Title: Open Data for Air Transport Research: Dream or Reality?

Authors: Marc Bourgois (EUROCONTROL Experimental Centre), Michael Sfyroeras (EUROCONTROL Experimental Centre)

Abstract: The role of open data in air transport research is analyzed by means of a sample of over 300 research articles. The most used (or available) data types, their sources and their access policies are identified, both for the US and the EU. The analyses show that 70% of research in air transport is heavily reliant on data, that 70% of the data sources are curated by governmental bodies and that the US publicizes a wider set of sources, leading to wider usage. Areas for improving accessibility of (mainly European) data sources are outlined and alternative avenues to obtain data are sketched. The fact that Europe is lagging considerably in making its sources readily available to the research community means Europe missing out on entrepreneurship, innovation and scientific discovery, the presumed benefits of open data.

Title: From Mashup Applications to Open Data Ecosystem

Authors: Timo Aaltonen (Tampere University of Technology), Tommi Mikkonen (Tampere University of Technology), Heikki Peltola (Tampere University of Technology), Arto Salminen (Tampere University of Technology)

Abstract: Web-based software is available all over the world instantly after the online release. Applications can be used and updated without need to install anything, with natural support for collaboration, which allows users to interact and share the same applications over the Web. In addition, numerous web services allowing users to upload, download, store and modify private and public resources have emerged. However, as the amount of web services and devices used to consume as well as generate data has exploded, it is difficult to access and manage relevant data. In this paper, we start from the principles of mashups, reflect their use to the concepts of software ecosystems, and finally extend the discussion to open data generated by users themselves. As a technical contribution, we also introduce our proof-of-concept implementation of a mashup system built on wellness data, and discuss the main lessons we have learned in the process.
