Maps, software, and shared knowledge

Talks I've given.

I speak about connecting OpenStreetMap and Wikidata, and the tools I build to make shared knowledge more useful.

These are appearances I've collected so far, including different versions of talks I've given more than once.

Bridging Worlds: Integration of Wikidata and OpenStreetMap

· Tartu, Estonia · 30 minutes

Read abstract: Bridging Worlds: Integration of Wikidata and OpenStreetMap — FOSS4G Europe 2024

Discover the synergy between Wikidata and OpenStreetMap, two monumental open data repositories. This talk unveils innovative web-based tools facilitating the linking of these platforms, enhancing the richness and accuracy of geospatial data.

OpenStreetMap's editors face a unique challenge: accurately mapping the vast tapestry of global locations. This presentation introduces Web-based solutions streamlining this process. Attendees will learn how these tools empower users to effortlessly identify and correlate Wikidata entries with OpenStreetMap locations. This integration, however, navigates complex waters of differing licenses, sparking lively debates within the community. The talk delves into these intricacies, exploring the ethical and legal considerations of cross-platform data sharing. Expect an engaging walk-through of the tool's latest iteration, insights into the matching algorithm, and an honest reflection on community responses, including the contentious aspects. The session concludes with a call to action, inviting attendees to contribute and further this pioneering work.

FOSSY 2023

Tools for linking Wikidata and OpenStreetMap

· Portland, Oregon, USA · 60 minutes

Read abstract: Tools for linking Wikidata and OpenStreetMap — FOSSY 2023

Wikidata and OpenStreetMap are collaborative open data projects that contain structured data for real world places and things. Adding links between the projects makes the data more useful, but doing this by hand is laborious. I've written a software tool that automates much of the process. Editors of OpenStreetMap can use my software to search for a place or region, generating a list of candidate matches from Wikidata, which can then be checked and saved to OpenStreetMap. Linking the two projects isn't without controversy. They use different licenses which raises questions about what information from one project can be copied to the other. In the presentation I will give details of a new version of the editing tool. I will talk about the benefits of linking, the process of finding matches, the community response - including the controversy - and how people can get involved.

I describe an editing tool for adding links from OpenStreetMap objects to the corresponding Wikidata items. https://osm.wikidata.link/

Mappers use the tool by searching for a place they are familiar with. The software downloads the details of Wikidata items within the bounds of the place and find matching objects in OpenStreetMap. The matcher compares places based on names, addresses and the type of object. The user is presented with a list of candidate matches, next to a map showing the matches. After the checks the matches are correct and then clicks a button to save the appropriate wikidata tags to OpenStreetMap. In the talk I will give details of a new version of the editing tool.

· Berlin, Germany · 25 minutes

With Eugene Alvin Villar

Read abstract: OpenStreetMap and Wikidata — WikidataCon 2019

An introduction to OpenStreetMap's data model and how linking it with Wikidata makes both datasets more useful.

The presentation compares the ways OpenStreetMap and Wikidata represent places and things, explains the benefits of linking them, and demonstrates a machine-assisted matching tool for adding Wikidata tags to OpenStreetMap objects. It also covers the tool's limitations and barriers to collaboration, including community concerns about relying on Wikidata and differences between the projects' licences.

· Heidelberg, Germany · 60 minutes

With Eugene Alvin Villar

Read abstract: OpenStreetMap and Wikidata: Awesome Together — State of the Map 2019

A workshop introducing Wikidata, how to contribute to it, and how OpenStreetMap and Wikidata can be used together.

The workshop compares the two projects' data models and explores existing links and collaborations between their communities. Participants learn to use a matching tool to find corresponding OpenStreetMap and Wikidata objects, review suggested matches, and save Wikidata tags to OpenStreetMap. It concludes with a discussion of opportunities for collaboration and barriers such as licence compatibility.
