ABSTRACT:
A content-based system and method for text processing and retrieval is provided wherein a plurality of pieces of text are processed based on content to generate an index for each piece of text, the index comprising a list of phrases that represent the content of the piece of text. The phrases are grouped together to generate clusters based on a degree of relationship of the phrases, and a hierarchical structure is generated, the hierarchical structure comprising a plurality of maps, each map corresponding to a predetermined degree of relationship, the map graphically depicting the clusters at the predetermined degree of relationship, and comprising a plurality of nodes, each node representing a cluster, and a plurality of links connecting nodes that are related. The map is displayed to a user, a user selects a particular cluster on the map, and a portion of text is extracted from said pieces of text based on the cluster selected by the user. The system may also generate scenarios, based on said maps, that indicate changes in the relationships shown by the maps.
