Claim One:
1. A method of topic summarization and content anatomy, comprising steps of: (a) decomposing a plurality of documents related to a topic into a non-overlapping sequence of a plurality of blocks and describing a theme-identifying problem with said blocks through a constraint optimization method to find and express a plurality of themes to obtain a matrix comprising a plurality of eigenvectors; (b) analyzing changes in said eigenvectors through an R-S endpoint detection algorithm to detect a plurality of temporally different events of each of said themes and obtain a plurality of summaries of said temporally different events; and (c) calculating a context similarity of each of said temporally different events to obtain a temporal closeness per two of said temporally different events, and so forth, to form an evolution graph of said topic by associating all of said temporally different events according to said temporal closeness of each of said temporally different events; wherein, in step (c), said context similarity of said event ⊖x is calculated to obtain a keyword vector through the following formula: e x · cv = 1 1 + e x · eb - e x · bb ⁢ ∑ i = e x · bb e x · eb ⁢  v i , e x · ev  ⋆ b _ i , ; wherein said temporal closeness of two of said events is calculated to obtain a temporal weigh through the following formula: TW ⁡ ( e i , e j ) = { 1 ⁢ e j · bb - e i · eb n , if ⁢ ⁢ e j · bb > e i · eb , 1 ⁢ 2 ⋆ ( min ⁡ ( e i · eb , e j · eb ) - e j · bb ) ( e i · eb - e i · bb ) + ( e j · eb - e j · bb ) , if ⁢ ⁢ e j · bb ≤ e i · eb .
