Claim 13:
14. The computing apparatus of claim 11, wherein determining the cross-correlation of the query matrix and the metadata-enriched text in the transcript matrix comprises:
transform the query matrix and the transcript matrix into a query word embedding matrix and a transcript word embedding matrix utilizing a multi-dimensional word embedding for each word in the query matrix and the transcript matrix, wherein the query word embedding matrix is created by replacing each word in the query matrix with the multi-dimensional word embedding for that word and the transcript word embedding matrix is created by replacing each word in the transcript matrix with the multi-dimensional word embedding for that word;
apply a fast Fourier transform to the transcript word embedding matrix and the query word embedding matrix to generate a transformed transcript word embedding matrix and a transformed query word embedding matrix;
determine a point-wise product of the transformed transcript word embedding matrix and the transformed query word embedding matrix; and
apply an inverse fast Fourier transform to the point-wise product to recover the cross-correlation of the transformed transcript word embedding matrix with the transformed query word embedding matrix.
