Personalized ranking for search results of a travel-related database query

A method of ranking search results, the method comprising:

• transmitting, by a computer, a search query to a database;
• receiving, by the computer, first search results from the database, the first search results comprising a first plurality of travel itineraries matching the search query;
• selecting, by the computer, a first travel itinerary and a second travel itinerary from the first plurality of travel itineraries based on a probabilistic profile of a traveler;
• receiving, at the computer, a first indication the traveler prefers the first travel itinerary to the second travel itinerary;
• updating, by the computer, the probabilistic profile of the traveler based on the first indication;
• determining, by the computer, a composite profile of the traveler based on the probabilistic profile;
• and
• ranking, by the computer, the first search results based on the composite profile.

A computer program product comprising:

• a non-transitory computer-readable storage medium;
• and
• program code stored on the non-transitory computer-readable storage medium that, when executed by a processor, causes the processor to:
• transmit a search query to a database of travel itineraries;
• receive search results from the database, the search results comprising a plurality of travel itineraries matching the search query;
• select a first travel itinerary and a second travel itinerary from the plurality of travel itineraries based on a probabilistic profile of a traveler;
• receive an indication the traveler prefers the first travel itinerary to the second travel itinerary;
• update the probabilistic profile of the traveler based on the indication;
• determine a composite profile of the traveler based on the probabilistic profile;
• and
• rank the search results based on the composite profile.
