A transformation processing system input data including a data record area for storing target date and a transformation processing identification information record area for storing transformation processing identification information about transformation processing executed upon the target data. The transformation processing system includes: a reverse transformation information recording unit which records a target data pointer indicating the data record area in transformed data, a transformation processing identification information pointer indicating the transformation processing identification information record area, and reverse transformation processing identification information about reverse transformation processing; a target data transformation unit which transforms the target data and records it in the data record area; and a transformation processing identification information recording unit which adds the transformation processing identification information about the transformation processing executed by the target data transformation unit to the transformation processing identification information record area in the input data.

Information, transformation and reverse transformation processing

Provides structured-document processing device for detecting a relationship of approximateness between structured documents effectively. State-transition-diagram information storing means stores information concerning a state transition diagram where source nodes of a source structured document transit in order of occurrence from the head thereof. Extracting means extracting, a pair consisting of a new node and a corresponding source node in accordance with order of occurrence. Matching means determining whether the source and new nodes in the selection pair have matchingness, on the basis of their descriptions. Node qualifying means qualifying the source node as a node to be used for the new node. Transition-history information generating means generates, as transition-history information, information concerning a transition history regarding the node to be used. Degree-of-approximateness detecting means detects a degree of approximateness between the source structured document and the new structured document on the basis of the transition-history information.
