1. A method in a system of a host organization, the system having at least a processor and a memory therein, wherein the method comprises: generating indices from a dataset of columns and rows, the indices representing probabilistic relationships between the rows and the columns of the dataset; storing the indices within a database system of the host organization; exposing the database system of the host organization via a request interface; receiving, at the request interface, a query for the database system specifying a GROUP command term and a specified column as a parameter for the GROUP command term; querying the database system using the GROUP command term and passing the specified column to generate a predictive record set; returning the predictive record set responsive to the query, the predictive record set having a plurality of groups specified therein, each returned group of the returned groups of the predictive record set including a group of one or more rows of the dataset; and wherein a confidence indicator returned with each respective row of the one or more rows specified within each group of the plurality of groups returned with the predictive record set ranges from a minimum of 0 indicating a lowest possible confidence in a result that the respective row belongs to the group specified to a maximum of 1 indicating a highest possible confidence in the result that the respective row belongs to the group specified.

The method of claim 1 , wherein the column passed with the GROUP command term provides the context of a latent structure in which the one or more rows of each specified group are assessed for similarity to any other rows within the same group, wherein the column passed with the GROUP command term provides the context of a latent structure in which the one or more rows of each specified group are assessed for similarity to any other rows within the same group.
