  • Patent number: 10152740
    Abstract: Methods, systems, and computer program products for generating recommendations. In response to receiving a request, the system generates a plurality of suggested recommendations for both a first bound and a second bound of a trip. The system stores the suggested recommendations corresponding to the first bound and the second bound in a memory, where the suggested recommendations corresponding to the second bound coincide to a subset of the suggested recommendations corresponding to the first bound published for display. The system publishes the suggested recommendations corresponding to the first bound for display to a user. In response to receiving an input that indicates a selected recommendation for the first bound, the system determines whether the selected recommendation is one of the subset of the suggested recommendations corresponding to the first bound.

  • Patent number: 10078858
    Abstract: Systems, methods, and computer program products for implementing a dynamic free-text search database. First data is generated for the dynamic free-text search database that represents a first relationship including a first keyword, a first trip, and a first weight value. A plurality of free-text search requests are received, and a second weight value for the first relationship is calculated based on the free-text search requests. The second weight value differs from the first weight value. The first data is transformed into second by inserting the second weight value into the first data such that the first relationship includes the second weight value.

  • Publication number: 20140324550
    Abstract: A method, system and computer program product assist an airline in determining if a lower fare exists for a trip among fares already proposed by the airline or other airlines. A set of tables, each associated with particular departure and arrival locations, may be created in an encompassing request database based upon results identified for requests sent from one or more clients, travel agents or airlines to a production traffic engine. The encompassing request database may then be queried by an airline to determine whether a lower fare exists for the trip.

  • Patent number: 8805826
    Abstract: The invention relates to a method and system for processing complex queries each corresponding to a plurality of components to be combined. Elements corresponding to these components are searched. The elements are of different element types and are originally described by definition data having heterogeneous data structures. A conversion step transforms the heterogeneous definition data into converted definition data of one single format. An engine then retrieves elements and builds associations of elements matching the query parameters based on the converted definition data, thereby providing with a reply to the query in an optimized manner.

  • Patent number: 8799184
    Abstract: A method for determining an optimal fare for a trip comprising a departure location, an arrival location, the method comprises the following steps: sending a request for the trip wherein the request comprises a departure location, an arrival location and a corresponding fare for the trip; automatically modifying the request by searching in a predetermined database to determine a set of additional requests wherein each comprises at least one of the departure location, the arrival location or one or more additional locations which may form at least a part of the requested route wherein the predetermined database comprises said additional requests and a corresponding fare for each additional request; selecting one or more additional requests to form one or more alternative requests which include at least on of the departure location or the arrival location as the request; calculating the up to date fares for each alternative request in order to determine a resulting fare for each alternative request; comparing t

  • Publication number: 20120095981
    Abstract: An aspect of the exemplary embodiments is an on-line system that includes an interface with system users configured to receive search requests from system users. The system further includes a search engine coupled with the interface. The search engine is configured to respond to a received search request from a user to perform a search that considers priceable criteria and a non-priceable criterion, where a weight of the non-priceable criterion to be accorded during the search relative to the priceable criteria is specified by the user. The search engine is further configured to return search results to the user via the interface. As an example, the search may be a travel-related search, the priceable criteria can include at least a fare amount, and the non-priceable criterion can include a universal criterion such as an ecology-related criterion.
