1. A method for placing candidate spines into a display with the aid of a digital computer, comprising:

  • generating candidate spines each comprising two or more clusters of documents, wherein each cluster is associated with one or more concept scores for concepts identified within the documents of that cluster;

    generating a concept score vector for each candidate spine by aggregating as spine concept scores, the cluster concept scores of the clusters associated with that candidate spine;

    normalizing each spine concept score in the spine concept score vector by dividing the spine concept score by a length of the spine concept score vector;

    ordering the candidate spines by a number of the clusters associated with each candidate spine;

    identifying those candidate spines sufficiently dissimilar from the other candidate spines based on the candidate spine concept score vectors;

    placing the sufficiently dissimilar candidate spines in a display; and

    placing at least a portion of the unplaced candidate spines in relation to the placed candidate spines.
