Abstract: A method for analysis of a set of media recordings includes, in a first processing stage, selecting a subset of the set of media recordings by performing a first processing of each media recording of the set of media recordings and in a second processing stage, performing a second processing of the subset of the set of media recordings, the second processing including extraction of information from the media recordings of the subset of the set of media recordings. The first processing of each media recording of the set of media recordings includes determining a characterization of the media recording, the characterization including at least a quantity characterizing a predicted performance of the second processing of the media recording.

Abstract: In an aspect, in general, a system includes a first input for receiving a first data representing an interaction among a plurality of parties, the first data identifying a plurality of parts of the interaction and identifying a plurality of segments associated with each part of the plurality of parts, a second input for receiving a second data associating each of one or more labels with one or more corresponding query phrases, a searching module for searching the first data to identify putative instances of the query phrases, and a classifier for labeling the parts of the interaction associated with the identified putative instances of the query phrases with the labels corresponding to the identified query phrases.
