Abstract : A Process for analyzing full-text is provided for identifying often-repeated, high user interest, word phrases in a database. Often-repeated, high user interest, word phrases are defined as pervasive theme areas (PTAs). The process also allows the relationship defined as con- nectivity among the various PTAs to be identified. In addition, phrases that are in proximity to the PTAs and which are strongly supportive of the PTAs are identified. Numerical indices, figure of merit, and user defined thresholds are used to quantify relations between PTAs and among PTAs and phrases.
