Classification: CPC G | IPC G

Claim 15:
16. One or more non-transitory computer-accessible storage media storing program instructions that when executed on or across one or more processors implement an analytics service and cause the analytics service to:
store, in a repository, respective sets of descriptors associated with individual ones of one or more reference objects, wherein a particular descriptor of a particular set of descriptors comprises information pertaining to a particular entity identified within a particular reference object;
in response to a first request to extract content from a particular data object, perform a content extraction on the particular data object, to:
identify a first reference object using a result of a first query directed to the repository, wherein the particular data object is distinct from the one or more reference objects including the first reference object, wherein the first reference object meets a similarity criterion with respect to the particular data object, wherein a parameter of the first query is based at least in part on output generated by a first set of one or more machine learning models to which the particular data object has been provided as input, and wherein the result of the first query is based at least in part on analysis of one or more descriptors associated with the first reference object;
based at least in part on the result of a first query, perform a structural comparison of the particular data object and the first reference object to determine a projection of respective portions of the particular data object onto the first reference object;
extract, using the projection, a first prediction of another entity associated with the particular entity in the particular data object; and
transmit the first prediction to one or more destination;
wherein the content extraction achieves a performance improvement based at least in part on use of the structural comparison of the particular data object with the first reference object, to (a) improve an accuracy of extracted content or (b) reduce an amount of compute, memory, or storage resources used to extract content.
