Our Citation Map team recently participated the Robert Raskin Mashup Competition in the Annual Conference of American Geographers. Our work has been selected as top 5, and is now in the public voting stage.
The voting page is below:
Our work is the #5, Citation Map.
We appreciate that if you could support us!
A significant amount of the work that we’ve been doing lately has made use of the plethora of user-generated, geospatially-related content publically available online. Web applications such as Yelp, Google Places and Foursquare provide access to tens of millions of points of interest (POI) worldwide. These POI offer a range of descriptive information ranging from semi-structured content such as price range ($$) and ambiance, to unstructured review text and personal user check-ins.

We designed a Citation Map for the Robert Raskin Mashup Mapping competition. This web mapping application is a novel approach to visualize research topics, authors, publications, as well as their citation relations on a world map. By displaying the geographic distribution of research paper citations, this dynamic web map shows how a scientific idea spreads through space and time (i.e. How a scientific publication is accepted and cited by researchers in different countries over the years). This Citation Map also shows the researchers who has cited a particular paper most frequently, and where are these researchers.
We have some good news to share -- Ben Adams successfully defended his PhD this Monday.
Thanks to this great occasion, we could all taste from the cake depicted below :-).
Geodata or more specifically places and locations play a key role on the Web of Linked Data by serving as nexuses that interconnect different data and data sources. Geonames, for instance, is one of the most linked hubs. In fact, most Linked Data are either directly or indirectly linked through various spatial and non-spatial relations to locations. Thus, it makes sense to dive deeper into investigating the role that place and location play, how many degrees (links) it takes before all Linked Data is connected to some sort of geo-feature, how these geo-features are represented, how their density is distributed, how to clean them up, and so forth. We started to do research on these topics some time ago and are preparing a paper. In the meantime we would like to show you some maps that illustrate the current state of locations on the Linked Data Web and the amount and types of errors we encountered. It turns out that more than 10% of these data has wrong or even impossible locations. We have found systematic errors and are beginning to figure out methods for cleaning them up. In case you are interested in Geospatial Semantics, Linked Spatiotemporal Data, and Geo-Ontologies you may also check out this short overview as starting point.
