7. A system for determining the origin or an area of influence of an author, comprising: a repository including non-transient computer readable storage; the repository having stored therein a plurality of areas, each area corresponding to a geospatial area in which a dialect is prevalent; the repository further having stored therein a plurality of dialect components each associated with a language and one of the areas; a display; and a processor in communication with the repository and configured to: receive a text communication, determine the language of the text communication, identify at least one dialect component associated with the language of the text communication is present in the text communication, retrieve from the repository the area to which the identified dialect component is associated; calculate a probability surface value according to P ij = 1 - ⋂ i = 1 n ⁢ d ij l j . where P ij is a probability surface value for the area contained by dialect area i for language j, l j is an area contained within language area j, d ij is an area contained by dialect polygon i for language j, and ∩ represents intersection; and present both representations of the retrieved areas and the probability surface value on the display.
