What do Wikidata and Wikipedia have in common? An analysis of their use of external references

Title: What do Wikidata and Wikipedia have in common? An analysis of their use of external references

Abstract: Wikidata is a community-driven knowledge graph, strongly linked to Wikipedia. However, the connection between the two projects has been sporadically explored. We investigated the relationship between the two projects in terms of the information they contain by looking at their external references. Our findings show that while only a small number of sources is directly reused across Wikidata and Wikipedia, references often point to the same domain. Furthermore, Wikidata appears to use less Anglo-American-centred sources. These results deserve further in-depth investigation.

About the Conference

The 12th International Symposium on Open Collaboration (OpenSym 2016) is the premier conference on open collaboration research and practice, including open source, open data, open education, wikis and related social media, Wikipedia, and IT-driven open innovation research.

OpenSym is the first conference series to bring together the different strands of open collaboration research and practice, seeking to create synergies and inspire new collaborations between computer scientists, social scientists, legal scholars, and everyone interested in understanding open collaboration and how it is changing the world.

OpenSym 2016 will be held in Berlin, Germany, on August 17-19, 2016.

Proceedings of OpenSym 2015 Made Available

Update 2015-09-18: The proceedings and the companion to the proceedings have been posted in the ACM Digital Library.

The proceedings of OpenSym 2015 can now be found on the proceedings page of the conference website. The papers will also appear in the ACM Digital Library (but haven’t posted yet). We will update the Archives page (which includes the proceedings from all years) once we get the information from the ACM.

Posters in the House (of Wiki Ed Foundation)

OpenSym is a conference with both the ability and the guts to experiment. This time, we had a joint welcome reception with the Wiki Ed Foundation. The welcome reception is also the primary place to show posters and demos. We were curious as to whether the location, a house in the Presidio, would work, and it did so marvellously. The more cozy atmosphere of a house (than a dreary conference room) got people talking much more easily. Thank you, Wiki Ed Foundation, for making this happen!

OpenSym 2015 Starts Tomorrow, Aug 19, in San Francisco’s Golden Gate Club

OpenSym 2015 will start tomorrow, Aug 19, at the Golden Gate Club at San Francisco’s Presidio. It is hard to find a more beautiful location and we still have space for online and on-site registrations. Participants are looking forward to a program chock-full of research and practitioner talks, a visit to the Wiki Education Foundation, and the following keynotes and invited talks, which are sure to inspire and ignite discussion and debate:

OpenSym 2015 Welcome Reception

We are excited to announce that the OpenSym 2015 Welcome Reception on Aug 19 will be held jointly with the Wiki Education Foundation at 11 Funston Avenue, Suite A, in the Presidio, San Francisco. The location is 0.4 miles walking distance from the Golden Gate Club, where OpenSym is held. Below please find an overview map. At the conference, we will provide additional instructions. The reception will start at 5pm (see the OpenSym 2015 program).

OpenSym 2015 Registration is Open!

Please register by July 12 for early bird prices. Expect a fabulous program with inspiring keynotes!

Preliminary OpenSym 2015 Program Announced

Please find the preliminary OpenSym 2015 program in this spreadsheet or in simple format below. In contrast to prior years, we decided this time to create a dense two-day program (still with open space on the second day). This is an experiment and in future years we may go back to the more relaxed three-day schedule. As always, please let us know your thoughts! Also, registration is open!

Anthony I. Wasserman on Barriers and Pathways to Successful Collaboration at OpenSym 2015

Anthony I. (Tony) Wasserman of CMU (Silicon Valley) will be presenting the following keynote at OpenSym 2015:

Title: Barriers and Pathways to Successful Collaboration

Abstract: Effective collaboration is essential to virtually every human endeavor, since there are relatively few significant tasks that can be accomplished by a single individual. Successful collaboration efforts can be ascribed to a shared vision, strong and charismatic leadership, and the ability to overcome technical, organizational, and personal obstacles to achieving the project’s objective(s). At the same time, there are many barriers that can make these efforts fail. While these barriers can’t always be overcome, the chances of success are greatly improved if people are aware of the various challenges and take steps to anticipate them in advance. This talk addresses these issues, and draws examples from the FLOSS community, from startups, and from other disciplines.

Biography: Anthony I. (Tony) Wasserman is a Professor of Software Management Practice at Carnegie Mellon University Silicon Valley, and the Executive Director of its Center for Open Source Investigation (COSI), focused on evaluation and adoption of open source software. In 1980, as a Professor at UC San Francisco, he released the software for his User Software Engineering research project under a BSD license. Subsequently, as CEO of Interactive Development Environments (IDE), he incorporated some of that software in IDE’s Software through Pictures multiuser modeling environment, released in 1984, making it among the very first commercial products to include open source software. After IDE, Tony was VP of Engineering for a dot-com, and later became VP of Bluestone Software, where Bluestone’s open source Total-e-Mobile toolkit allowed mobile devices to connect to JavaEE web applications. Tony is very active in the international open source research community, and served as General Chair of the 2009 and 2014 Int’l. Conference on Open Source Systems. He is on the Board of Directors of the Open Source Initiative (OSI) and the Board of Advisors of Open Source for America Tony is a Fellow of the ACM and a Life Fellow of the IEEE for his contributions to software engineering and software development environments. He received the 2012 Distinguished Educator Award from the IEEE’s Technical Council on Software Engineering and the 2013 Influential Educator Award from the ACM’s Special Interest Group on Software Engineering. Tony has been to almost 70 countries, including some that no longer exist, and posts his photos on Flickr.
