Systems and methods for machine-based matching of lodging inventory from a plurality of disparate reservation provider systems address the difficulties inherent in comparing prices to obtain a lowest possible price, which difficulties are inherent in the distribution of inventory to multiple third-party reservation providers who are generally permitted to utilize their own naming conventions when describing lodging inventory and who are also free to at least some extent to set prices for the various lodging inventory within their control. The systems and methods match room types using information obtained from the multiple third-party reservation providers, whereby direct comparisons can be made between prices for the same room types even when the reservation providers do not utilize identical descriptions or naming conventions for the respective room inventories.
