1. Recommending Places Through
Geospatial Analysis of Real-Time
Geostreams
Andrew Dalgleish
University of Texas at Dallas ● GIS Workshop – Summer 2010
Final Presentation
July 29-30, 2010

2. Project + Objectives
Develop System for Collection and Analysis of Spatial-
Temporal Data from Web Services
Provide Web Based Map tool for viewing Places and
Recommendations
Use of Open-Source GIS Software and
Standards

3. Similar Projects + Research
Sites such as FourWhere.com, TrendsMap.com and Twitris.knowsis.
org provide thematic map visualizations of social network data.
Location-Based Features in Google, Foursquare, and Facebook.
CityVoyager (Microsoft Research) and GeoLife (Takeuchi &
Sugimoto) – Collaborative Filtering based on user travel history, as
tracked by GPS
Difference between “Location” and “Place”: They both tell you where you are, but
one is spatially precise, the other is contextually precise.

4. Twitter Data Stream (July 10-25, 2010)

5. Entity Relationship Diagram

6. Calculate User Similarity

8. And Now… A Demo

9. Problems & Lessons Learned
Resolving Place-Equivalance across Social Networks
People checking into their “homes”
Hosting Provider Amazon / Media Temple (ve) / Google App Engine
Follow @ManningBooks to get 50% off eBooks
Code Reuse! codeplex.com / github / code.google.com

10. Conclusions & Future Work
Addition of new social network logins (yelp, Facebook, Gowalla)
Factor ratings into results
Ability to search for places by name, add to “Favourites”, to get
recommendations without social network login
More spatial analysis possibly leading to algorithms for Collaborative
Filtering
Mobile Application
