Task-oriented information value measurement based on space-time prisms

Our recent work on measuring the value of information has been accepted by the International Journal of Geographical Information Science. The proposed framework provides a potential solution for prioritized information display on small-screen devices, such as smartwatches.

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.

Workshop on Geographic Information Observatories 2014 call for paper

Our workshop proposal has been accepted by the GIScience 2014 conference, which will be held in Vienna, September, 23-26. The title of the workshop is called Geographic Information Observatories. In this workshop we would like to explore the idea of expanding GIScience research to empirically examine the structure of the geographic information universe itself, with the hope that a better understanding of this universe will ultimately give us new insights into how this information can be utilized.
