Torre, F., Sheppard, S. A., Priedhorsky, R., Terveen, L., bumpy, caution with merging: An Exploration of Tagging in a Geowiki, ACM GROUP 2010, Nov 7-10, 2010, Sanibel Island, FL, USA.

We studied how users applied and used tags in the Cyclopath system, given that tags were shared by the community and could be used to specify routing preferences (e.g. avoid roads with the hill tag).

Skills used: UI Evaluation, Data and Content Analysis

Torre, F., Pitchford, D., Brown, P., Terveen, L., Matching GPS Traces to (Possibly) Incomplete Map Data: Bridging Map Building and Map Matching, 20th ACM SIGSPATIAL GIS, Nov 6-9, 2012, Redondo Beach, CA, USA.

In this short paper, I extended an algorithm that matches GPS traces to roads on a map in order to detect missing roads. The idea is to suggest roads for users to add to the system based on their bike rides.

Skills used: Algorithms

Torre, F., Liu, Y., Liu, Z., Terveen, L., Local Knowledge Matters for Crowdsourcing Systems: Experience from Transferring an American Site to China, 7th ICWSM, July 8-10, 2013, Boston, MA, USA.

We created an experimental version of the Cyclopath bike map for Dalian, China and interviewed 40 local cyclists. In this short paper, I wrote about our experiences and findings.

Skills used: User Studies, Usability, Localization (l10n), Internationalization (i18n)

Torre, F., Techniques for Improving Routing by Exploiting User Input and Behavior, Ph.D. dissertation, University of Minnesota, 2014.

As part of my Ph.D. Thesis, I added to the previous work by conducting experiments on both mobile and web to explore how to encourage users to add route landmark information.

Skills used: Android development, User Studies, Experiment Design
