  • Patent number: 12259920
    Abstract: Disclosed embodiments provide techniques for monitoring and evaluating the effectiveness of key value pairs (KVPs) used in a document processing system. In embodiments, KVPs are obtained from multiple extractors of a document processing system. A score is computed for the KVPs by computing an effectiveness metric for each KVP from the multiple KVPs. In response to the computed score being below a predetermined threshold, a model retraining process is performed to generate a new set of KVP extractors, and provide the new set of KVPs to the document processing system.

  • Patent number: 12235836
    Abstract: A system that enables searching for representing listings for accommodation reservations on a map is described. The system receives, by a network site of a listing network platform, input comprising search criteria associated with a geographical region and identifies a plurality of listings matching the search criteria. The system identifies a first subset listings of the plurality of listings that is each associated with a respective location that is within a boundary associated with the geographical region and a second subset listings of the plurality of listings that is each associated with a respective location that is outside the boundary associated with the geographical region. The system visually distinguishes the first subset of listings from the second subset of listings on a map-based graphical user interface (GUI) that represents the plurality of listings matching the search criteria.

  • Publication number: 20250028569
    Abstract: A method for providing shuffle templates and using the shuffle templates to implement shuffling of data among workers comprising compute resources in a data center includes providing, by a shuffle manager, an application programming interface (API) through which applications can select shuffle templates and specify data to be processed by the workers in the data center using the shuffle templates to distribute the data as messages transmitted among the workers. The shuffle manager receives a call for a shuffle template including a shuffle template identifier source and destination identifiers for processing by the workers. The shuffle manager selects the shuffle template identified by the call for the shuffle template and provides the shuffle template to the workers. Workers use the shuffle template to generate a shuffle plan and use the shuffle plan to shuffle the messages among the workers between the sources and the destinations.
