Systems, Methods, And Computer Program Products For Searching And Displaying Low Cost Product Availability Information For A Given Departure-Return Date Combination Or Range Of Departure-Return Date Combinations

US Patent:
2005027, Dec 8, 2005
Filed:
May 20, 2005
Appl. No.:
11/133688
Inventors:
Alan Walker - Southlake TX, US
Yanjun Zhang - Plano TX, US
Dirk Guenther - Roanoke TX, US
International Classification:
G06F017/60
US Classification:
705005000
Abstract:
The present invention generates a grid of low-priced fare combinations for either a selected departure and return date or a range of departure and return dates. The present invention uses various techniques to reduce processing and delay in generating the grids. The present invention first converts flight itineraries for the selected departure and return dates or the range of dates into the fare domain. The invention discards fare combinations that are not valid for the given travel request. The valid fare combinations are processed to determine which has the lowest fare price. The fare combinations are processed one at a time starting with the cheapest fare combination to determine which of the possible flight itineraries may be covered by the fare combination. The invention may use additional prunning steps to validate the fare combinations prior to application to individual flight itineraries. As each fare combination is matched to a flight itinerary, the grid is populated with this fare combination.

Methods, Systems, And Articles Of Manufacture For Providing Product Availability Information

US Patent:
2003008, May 8, 2003
Filed:
Nov 4, 2002
Appl. No.:
10/286891
Inventors:
Joseph Offutt - Grapevine TX, US
Tony Brice - Colleyville TX, US
Alan Walker - Southlake TX, US
Barry Smith - Flower Mound TX, US
Assignee:
Sabre Inc.
International Classification:
G06F017/60
US Classification:
705/022000
Abstract:
Methods and systems consistent with certain aspects related to the invention provide product availability information to a requestor via a proxy computer. In one aspect, a proxy computer that acts on the behalf of a seller computer receives product inventory information and one or more inventory control rules provided by the seller computer. In response to an availability request provided by a user, the proxy computer may determine product availability information based on the product inventory information and the one or more inventory control rules. Further, the proxy computer may be configured to update at the product inventory information and/or one or more control rules based on a determination that the seller computer has updated the same information stored in a database.

System, Method, And Computer Program Product For Improving Accuracy Of Cache-Based Searches

US Patent:
2006014, Jul 6, 2006
Filed:
Jan 6, 2005
Appl. No.:
11/030494
Inventors:
Alan Walker - Southlake TX, US
International Classification:
G06F 17/30
US Classification:
707003000
Abstract:
A system, method, and computer program product search a cache database in response to a search request from a user, determine which of the search results is most likely to be preferred by the user, and verify the preferred results against a real-time database. If the verification determines that the preferred results are accurate, then all the search results are provided to the user. If the verification determines that the preferred results are not accurate, then those results are deleted and the remaining results are provided to the user. As a result, the accuracy of the results returned to the user is increased, while queries of the real-time database are utilized only where most useful and are thereby reduced.

System, Method, And Computer Program Product For Finding Web Services Using Example Queries

US Patent:
8041727, Oct 18, 2011
Filed:
Jan 6, 2005
Appl. No.:
11/030463
Inventors:
Alan Walker - Southlake TX, US
Assignee:
Sabre Inc. - Southlake TX
International Classification:
G06F 17/30
US Classification:
707765, 707780
Abstract:
A system, method, and computer program product allows a web service consumer to create an example query which illustrates the web service desired. The example query is compared, element by element, to potentially relevant web services. The difference between each element in the example query and any element in the web service being compared is quantified as a distance metric, based on the relationship between the elements. The relationships might be classified as: exact match, direct synonym, fuzzy synonym, hyponym, hypernym, or no match. The distance metric for each element in the example query is summed to calculate a total distance between the example query and the web service being compared. This sum is an expression of the difference between the example query and the web service being compared.
