Abstract: An exemplary method may comprise receiving a matrix for a set of documents, each cell of the matrix including a frequency value indicating a number of instances of a corresponding text segment in a corresponding document, receiving an indication of a relationship between two text segments, each of the two text segments associated with a first column and a second column, respectively, of the matrix, adjusting, for each document, a frequency value of the second column based on the frequency value of the first column, projecting each frequency value into a reference space to generate a set of projection values, identifying a plurality of subsets of the reference space, clustering, for each subset of the plurality of subsets, at least some documents that correspond to projection values, and generating a graph of nodes, each of the nodes identifying one or more of the documents corresponding to each cluster.

Abstract: A closure for press-on application to, and rotational removal from, a container having a cylindrical neck which includes a plurality of vertically spaced helical threads formed in the outer surface thereof in generally parallel relationship to each other. A flexible cylindrical skirt, preferably composed of a polyolefin such as polypropylene, includes a plurality of radially inwardly projecting spaced lugs that are circumferentially disposed around the inner cylindrical skirt surface and axially spaced therefrom for engagement with the threads on the cylindrical neck of the container. The lugs are composed of a deformable plastic material and are sized so that when the closure is applied to the container, an interference fit is provided between at least some of the lugs and at least some of the threads.
