Abstract: A method in an aggregator includes: storing (i) previous search results generated by supplier subsystems, in response to previous search requests, and (ii) for each previous search result, an identifier of the supplier subsystem that generated the previous search result; receiving a current search request containing current search parameters; responsive to receiving the current search request, selecting a set of the supplier subsystems for search result generation; for a first supplier subsystem from the set, retrieving from storage a previous search result associated with a second supplier subsystem from the set, based on correspondence between the search parameters and attributes of the previous search results; and sending, to the first supplier subsystem, (i) the current search request, and (ii) auxiliary search parameters corresponding to the retrieved previous search result, for generation of current search results at the first provider subsystem employing the auxiliary search parameters as inputs.

Abstract: A method at an aggregator includes: storing previous search results resulting from previous client search requests, and for each previous search result, a previous handling indicator, indicating a relevance of the previous search result to the client; receiving, from the client, a search request containing search parameters; in response to the search request, selecting a subset of previous search results based on correspondence between attributes of the previous search results and the search parameters, and on the previous handling indicators; providing, to a supplier, the search request and auxiliary search parameters corresponding to the selected previous search results and indicating characteristics of the selected previous search results, for generation of current search results at the supplier employing the auxiliary search parameters as inputs; receiving, from the supplier, the current search results generated at the supplier; and returning at least one of the current search results to the client.

Abstract: A method includes: at an aggregator, storing historical data representing: (i) a plurality of previous search requests received at the aggregator, and (ii) for each previous search request, an outcome indicator defining whether a supplier subsystem generated previous search results meeting a relevance threshold in response to the previous search request; receiving, at the aggregator from a client subsystem, a search request containing a set of client search parameters; in response to receiving the search request, determining, based on the search request and the historical data, a likelihood of the supplier subsystem generating search results meeting the relevance threshold; and selecting, according to the likelihood, a routing action for the search request, relative to the supplier subsystem.

Abstract: A device, system and method for providing provider objects from a cache is provided. Provider objects are received representing items provided by provider systems. The provider objects are categorized by reusability and/or context characteristics and stored as categorized. A request is received for one or more items provided by the one or more provider systems. A stored and categorized provider object is determined to meet criteria associated with the request, including one or more of a respective reusability and respective context characteristics of the provider object. In response to determining that the provider object, that meets the criteria, is estimated to be currently valid, a response corresponding to the provider object is provided.

Abstract: A device, system and method for training machine learning models using messages associated with provider objects is provided. One or more computing devices: receives messages associated with provider objects representing items provided by provider systems, the messages having more than one format; stores harmonized objects corresponding to the messages, the harmonized objects generated using mappings of harmonized data of the harmonized objects to message data of the messages, the harmonized objects having common formats for a harmonized object type; extracts, from the harmonized objects, for a given machine learning model, given machine learning training data; generates, for the given machine learning model, using the given machine learning training data, at least one machine learning classifier; and provides the at least one machine learning classifier to the given machine learning model at one or more servers configured to implement the given machine learning model on received provider objects.
