About the STKO Lab

Do you like astronomy, the universe? Great, 'cause we are the astronomers of the information universe. The STKO Lab is an information observatory that investigates the role of Space and Time for Knowledge Organization. Thus, if you like, you can also spell out the STKO acronym as Spatio- Temporal Knowledge Observatory. Our work spans across different scientific disciplines such as geoinformatics & GIScience, cognitive science, computer science, and the broader earth sciences. While our research interests vary, we typically work on topics related to geospatial semantics, ontologies, and the Semantic Web, spatial data science, (location-based) social networks and volunteered geographic information, geographic information retrieval, Linked Data, Big Data, similarity and analogy-based reasoning, as well as mobile computing and location-based services.

A key driver for our work is the question of how to foster the publishing, retrieval, reuse, and integration of data without restricting semantic heterogeneity which we consider a motor of (interdisciplinary) science. We are also very interested in exploratory user interfaces and novel interaction paradigms to browse and navigate unfamiliar data. Methodologically, our niche is the combination of theory-driven (e.g., semantics) and data-driven (e.g., data mining) approaches. While we will be adding content to this page over time, you can find up-to-date information about our research, publications, and organized events following the links from the people site.

Place2Vec Ground Truth Data Available

We have presented our Place2Vec paper at this year's ACM Sigspatial conference and have attracted a lot of attention. In order to promote future research in place type similarity measurements, we have published the ground truth data we collected using Amazon Mechanical Turk. You can download the data from this repository: https://github.com/BoYanSTKO/place2vec .

We are recruiting new graduate students

The STKO Lab at UCSB is looking for highly-motivated and talented students to further strengthen our team. Please contact Krzysztof Janowicz, ideally before you apply. STKO works on a wide range of topics and our work style and the lab's atmosphere is what you would typically expect from a start-up. We are a very dynamic and well-funded team with projects from NSF, government agencies, and key industry players. Previous STKO students scored top jobs in industry and academia.
