SYSTEM AND METHOD FOR MULTI-FACTORED-BASED RANKING OF TRIPS

摘要

A trip-planning method and system employ a user profile for each user which includes the user's preferences for each of a plurality of transportation modes, user goals, and optionally user constraints on trips. Inferred user preference (resp. goal) values and stated user preference (resp. goal) values are aggregated using a coefficient which places more emphasis on stated goals/preferences that have been recently set. Candidate itineraries for a requested user trip that meet the user's constraints are ranked based on the aggregated goal and preference values and the costs/contributions of each itinerary to the respective goal/preference. A subset of the ranked itineraries may be output to the user for the user to select one for making the trip.
