Multi-section sequential document modeling for multi-page document processing

A document processing system configured for document classification, the system comprising:

• a host computing platform comprising one or more computers, each with memory and at least one processor;
• a table disposed in the memory and correlating different sequences of tags with different document classes;
• and,
• a document classification module comprising computer program instructions executing in the memory of the platform, the instructions performing:
• loading a multi-page document into the memory;
• processing a multiplicity of pages of the multi-page document in the memory, page by page, and for each of the pages, determining whether the page contains a transition from one section to another, or if the page contains no transitions from one section to another;
• constructing for the multi-page document, a sequence of tags in the memory beginning with an initial tag for an initial one of the pages and then a next tag for a next one of the pages and continuing with a different tag for each of the pages in sequential order of the pages leading to a final tag corresponding to a final one of the pages, each tag in the sequence indicating whether a corresponding one of the pages includes or lacks a transition;
• comparing the constructed sequence to the different sequences in the table in order to identify a matching one of the sequences;
• and,
• classifying the multi-page document according to a classification correlated to the matching one of the stored sequences.

A computer program product for document classification, the computer program product including a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a device to cause the device to perform a method including:

• loading a multi-page document into memory of a computer;
• processing a multiplicity of pages of the multi-page document in the memory, page by page, and for each of the pages, determining whether the page contains a transition from one section to another, or if the page contains no transitions from one section to another;
• constructing for the multi-page document, a sequence of tags in the memory beginning with an initial tag for an initial one of the pages and then a next tag for a next one of the pages and continuing with a different tag for each of the pages in sequential order of the pages leading to a final tag corresponding to a final one of the pages, each tag in the sequence indicating whether a corresponding one of the pages includes or lacks a transition;
• comparing the constructed sequence to a set of previously stored sequences in order to identify a matching one of the stored sequences;
• and,
• classifying the multi-page document according to a classification previously associated with the matching one of the stored sequences.
