Introduction
• Location-based Data Network (LBSN)• Restaurants performance prediction
• Research Questions:• Extract and combine different geographical or mobility
features.• Detect causal effects of location-based features on restaurant
performance
3
Literature Review
• Restaurant performances prediction• Location-based data usage• Features extraction (2 types)• Features combination (machine-learning-based techniques)• Data source (Foursquare check-ins dataset)
Model and Methods
• Features:• Static geographical features: • Dynamic consumer mobility features:• Restaurants specific features:

Model and Methods
5
• Step 1 Classification• Using to cluster locations with similar characteristics• Prepare for causal effects examinations
• Step 2 Prediction
Basic economic/behavior model using
Final prediction

Data
• Online reservation system• Reservation availability information• Restaurant specific information
• Location-based service & Social media

Challenges
• Choice of basic economic/behavior model• Modification of the basic economic model (or feature
combination)• Classification for the purpose of causal effect
examination

Potential Implication
• Help business managers decide a new location• Help policy makers understand local economy• Help location-based service to improve their
performance
