Claim 6

A computer program product for archiving both a multi-media object and an associated description composed in a natural language, comprising: a computer readable storage medium having a computer program stored thereon for performing the steps of: (a) receiving the description composed in natural language to be associated with the multi-media object; (b) recognizing the syntactic and semantic structure of the of the description; (c) based on step (b), assigning a role representation of the description, which said role representation further comprises assigning agent role that indicates an actor who is performing an action, an action role that identifies an activity that is being performed, and a patient role that identifies an object affected in some way by the action, for storage in an archival database.

Claim 7

A computer program product for archiving both a multi-media object and an associated description composed in a natural language, comprising: a computer readable storage medium having a computer program stored thereon for performing the steps of: (a) receiving the description composed in natural language to be associated with the multi-media object; (b) recognizing the syntactic and semantic structure of the of the description; (c) based on step (b), assigning a role representation of the description, which said role representation further comprises assigning agent role that indicates an actor who is performing an action, an action role that identifies an activity that is being performed, and a patient role that identifies an object affected in some way by the action, for storage in an archival database.
