STKO at GIScience '14

From Sep 23-26, 2014, Our STKO members and alumni participated in the Eighth International Conference on Geographic Information Science (GIScience 2014) in Vienna, Austria.
Prof. Janowicz co-authored a full paper: “Linked Data - A Paradigm Shift for GIScience” by Werner Kuhn, Tomi Kauppinen and Krzysztof Janowicz.

POI Pulse paper accepted for publication

Just a quick update to mention that our paper POI Pulse: A multi-granual, semantic signatures-based information observatory for the interactive visualization of big geosocial data by Grant McKenzie, Krzysztof Janowicz, Song Gao, Jiue-An Yang and Yingjie Hu was accepted for publication through Cartographica: The International Journal for Geographic Information and Geovisualization.

A cartographic approach to visualize research topics in the 2013 WWW conference

Recently, we have designed a Web-based application to visualize the spatiotemporal evolution of Web related research topics (See the previous blog here). In this application, a word-cloud-based timeline has been employed to visualize the evolution of research topics on the Web. While word clouds have been a popular way to display the prominent terms, they are unable to reveal the relations among the research topics.

Web@25: Exploring the Web-related research topics in space and time

With people around the world celebrating the 25th birthday of the Web, the STKO lab is not an exception. To contribute to this great festival, we designed a Linked-Data powered Web portal using the state-of-the-art Semantic Web technologies. As a lab focusing on spatiotemporal knowledge and information observatory, this Web portal features an exploration of the evolution of Web-related research topics.
