7. Logic encoded in one or more non-transitory tangible media for execution and when executed operable for: providing a non-optimized list of elements, with some of the elements having multiple terms, the elements being adapted for use in improving recognition accuracy of a speech-recognition system through at least one of supervised adaptation and unsupervised adaptation, generating, by a processor circuit, a table of sub-elements from the elements list, with each sub-element having one term only and with a number of times a sub-element appears in the elements list being weighted in the sub-elements table, generating, by the processor circuit, a weighted singleton histogram table using a singleton dictionary, and computing a total popularity score of each singleton from the sub-elements table, for each element from the elements list, generating by the processor circuit, an elements score based on the total popularity score of each singleton within the element, and generating, by the processor circuit, an optimally sorted list of the elements list based on the elements scores.
