Method, apparatus, and computer program product for routing files within a document management system
View Patent ↗A method, apparatus, and computer program product are provided for routing files within a document management system. The document management system may comprise or may otherwise communicate with an Optical Character Recognition (OCR) system and Full Text Search (FTS) indexing system. Files may be fed to a file routing apparatus with different priorities based on an originating source. The files may be routed for OCR processing and/or FTS indexing based on file and/or document types, licensing, and/or the like. Images and corresponding machine-readable text may be archived. Text may be FTS indexed so that the associated files may be identified and accessed by various client systems.
1. A method comprising:
receiving an indication of a received file;
queuing the received file into a file classifier queue; and
with a processor, processing a file from the file classifier queue by:
a) determining at least one of a file type or a document type of the file from the file classifier queue;
b) based on one or both of the file type or the document type, classifying the file from the file classifier queue as an unsupported file, an Optical Character Recognition (OCR) eligible file, or a Full Text Search (FTS) eligible file;
c) in an instance in which the file from the file classifier queue is an OCR eligible file, queuing the OCR eligible file into an OCR queue for OCR processing; and
d) in an instance in which the file from the file classifier queue is an FTS eligible file, queuing the FTS eligible file into a FTS queue for FTS indexing.
2. The method of claim 1 , further comprising, asynchronously from the processing of the file from the file classifier queue, processing an OCRed file, wherein the OCRed file is a result of the OCR processing, and the processing of the OCRed file comprises:
determining whether the OCRed file comprises machine-readable text;
in an instance in which the OCRed file comprises machine-readable text, queuing the OCRed file into the FTS queue; and
in an instance in which the OCRed file does not comprise machine-readable text, preventing the OCRed file from being queued into the FTS queue.
3. The method of claim 1 , further comprising:
causing asynchronous processing of the OCR queue and asynchronous processing of the FTS queue.
4. The method according to claim 1 , wherein the received files are received from one of a release server or a backload queue, and the method further comprises:
queuing received files from the release server with a higher priority than the received files from the backload queue.
5. The method according to claim 1 , wherein classifying the file from the file classifier queue as an OCR eligible file comprises determining that a source of the file from the file classifier queue has an OCR license.
6. The method according to claim 1 , wherein classifying the file from the file classifier queue as an FTS eligible file comprises determining that the file from the file classifier queue comprises machine-readable text.
7. The method according to claim 1 , wherein classifying the file from the file classifier queue as an OCR eligible file is based on a user configuration of the document type.
8. The method of claim 1 , wherein the document type describes at least locations of expected text compared to white space in the file and wherein the file is classified based on the locations of the expected text.
9. The method of claim 1 , wherein at least one of the file type or the document type is determined by accessing metadata stored in association with the file, and wherein the classification is based on at least the metadata stored in association with the file.
10. The method of claim 1 , wherein the file type indicates a file type extension, and wherein the classification is based on at least the file type extension.
11. The method of claim 1 , wherein at least one of the file type or the document type is based on identification of a client application having transmitted or generated the file, and wherein the classification is based on at least the client application having transmitted or generated the file.
12. A computer program product comprising at least one non-transitory computer-readable medium having computer-readable program instructions stored therein, the computer-readable program instructions comprising instructions, which when performed by an apparatus, are configured to cause the apparatus to perform at least:
receiving an indication of a received file;
queuing the received file into a file classifier queue; and
processing a file from the file classifier queue by:
a) determining at least one of a file type or a document type of the file from the file classifier queue;
b) based on one or both of the file type or the document type, classifying the file from the file classifier queue as an unsupported file, an Optical Character Recognition (OCR) eligible file, or a Full Text Search (FTS) eligible file;
c) in an instance in which the file from the file classifier queue is an OCR eligible file, queuing the OCR eligible file into an OCR queue for OCR processing; and
d) in an instance in which the file from the file classifier queue is an FTS eligible file, queuing the FTS eligible file into a FTS queue for FTS indexing.
13. The computer program product of claim 12 , wherein the computer-readable program instructions are further configured to cause the apparatus to perform at least:
asynchronously from the processing of the file from the file classifier queue, processing an OCRed file, wherein the OCRed file is a result of the OCR processing, and the processing of the OCRed file comprises:
determining whether the OCRed file comprises machine-readable text;
in an instance in which the OCRed file comprises machine-readable text, queuing the OCRed file into the FTS queue; and
in an instance in which the OCRed file does not comprise machine-readable text, preventing the OCRed file from being queued into the FTS queue.
14. The computer program product of claim 12 , wherein classifying the file from the file classifier queue as an OCR eligible file comprises determining that a source of the file from the file classifier queue has an OCR license.
15. The computer program product of claim 12 , wherein classifying the file from the file classifier queue as an FTS eligible file comprises determining that the file from the file classifier queue comprises machine-readable text.
16. The computer program product of claim 12 , wherein classifying the file from the file classifier queue as an OCR eligible file is based on a user configuration of the document type.
17. An apparatus comprising processing circuitry configured to cause the apparatus to perform at least:
receiving an indication of a received file;
queuing the received file into a file classifier queue; and
processing a file from the file classifier queue by:
a) determining at least one of a file type or a document type of the file from the file classifier queue;
b) based on one or both of the file type or the document type, classifying the file from the file classifier queue as an unsupported file, an Optical Character Recognition (OCR) eligible file, or a Full Text Search (FTS) eligible file;
c) in an instance in which the file from the file classifier queue is an OCR eligible file, queuing the OCR eligible file into an OCR queue for OCR processing; and
d) in an instance in which the file from the file classifier queue is an FTS eligible file, queuing the FTS eligible file into a FTS queue for FTS indexing.
18. The apparatus of claim 17 , wherein the processing circuitry is further configured to cause the apparatus to perform at least:
