  • System and Method for Discovering Latent Relationships in Data
    Publication number: 20100114890
    Abstract: A computerized method of querying an array of vectors includes receiving a first matrix, partitioning the first matrix into a plurality of subset matrices, and processing each subset matrix with a natural language analysis process to create a plurality of processed subset matrices.
