Abstract

A method includes defining a plurality of known document types, obtaining a collection of previously classified documents that are each associated with one of the known document types, and extracting features from each document from the collection of previously classified documents to define feature information. The method also includes obtaining a subject document that is associated with a user, extracting one or more features from the subject document, comparing the one or more features from the subject document to the feature information, associating the subject document with one of the known document types based on the comparison, and transmitting the document to a cloud storage system for storage in a dedicated storage location that is associated with the user and contains only documents of the respective known document type that is associated with the subject document.

Claims

1. A method comprising:

defining a plurality of known document types;

obtaining a collection of previously classified documents that are each associated with a respective document type from the plurality of known document types;

extracting features from each document from the collection of previously classified documents to define feature information describing features extracted from the collection of previously classified documents;

obtaining a subject document that is associated with a user;

extracting one or more features from the subject document;

comparing the one or more features from the subject document to the feature information;

associating the subject document with one of the known document types based on the comparison of the one or more features from the subject document to the feature information; and

transmitting the document to a cloud storage system for storage in a dedicated storage location that is associated with the user and contains only documents of the respective known document type that is associated with the subject document.

2. The method of claim 1, wherein the subject document is an attachment to an email message.

3. The method of claim 1, wherein obtaining the subject document includes accessing an email message having an email attachment and storing a copy of the email attachment as the subject document.

4. The method of claim 1, wherein the subject document is a photograph.

5. The method of claim 4, wherein obtaining the subject document includes accessing a collection of photographs that are associated with the user and storing a copy of one of the photographs from the collection of photographs as the subject document.

6. The method of claim 1, wherein the one or more features are alphanumeric text-based features that include at least one of text size, text font, text positioning, or substantive text content.

7. An apparatus comprising:

a memory; and

a processor configured to execute instructions stored in the memory to;

define a plurality of known document types;

obtain a collection of previously classified documents that are each associated with a respective document type from the plurality of known document types;

extract features from each document from the collection of previously classified documents to define feature information describing features extracted from the collection of previously classified documents;

obtain a subject document that is associated with a user;

extract one or more features from the subject document;

compare the one or more features from the subject document to the feature information;

associate the subject document with one of the known document types based on the comparison of the one or more features from the subject document to the feature information; and

transmit the document to a cloud storage system for storage in a dedicated storage location that is associated with the user and contains only documents of the respective known document type that is associated with the subject document.

8. The apparatus of claim 7, wherein the subject document is an attachment to an email message.

9. The apparatus of claim 7, wherein obtaining the subject document includes accessing an email message having an email attachment and storing a copy of the email attachment as the subject document.

10. The apparatus of claim 7, wherein the subject document is a photograph.

11. The apparatus of claim 10, wherein obtaining the subject document includes accessing a collection of photographs that are associated with the user and storing a copy of one of the photographs from the collection of photographs as the subject document.

12. The apparatus of claim 7, wherein the one or more features are alphanumeric text-based features that include at least one of text size, text font, text positioning, or substantive text content.

13. A method comprising:

obtaining a document that is associated with a user;

extracting one or more features from the document;

comparing the one or more features from the document to receipt feature information describing features extracted from a collection of sales receipts;

determining that the document is a sales receipt based on the comparison of one or more features from the document to the receipt feature information; and

transmitting the document to a cloud storage system for storage in a dedicated receipt storage location that is associated with the user.

14. The method of claim 13, wherein the document is an attachment to an email message.

15. The method of claim 13, wherein obtaining the document includes accessing one or more email messages and storing copies of one or more email attachments from the one or more email messages as the one or more documents.

16. The method of claim 13, wherein the one or more documents are photographs.

17. The method of claim 16, wherein obtaining the document includes accessing a collection of photographs that are associated with the user and storing copies of one or more photographs from the collection of photographs as the one or more documents.

18. The method of claim 13, wherein the one or more features are alphanumeric text-based features that include at least one of text size, text font, text positioning, and substantive text content.

19. An apparatus comprising:

a memory; and

a processor configured to execute instructions stored in the memory to;

obtain a document that is associated with a user,

extract one or more features from the document,

compare the one or more features from the document to receipt feature information describing features extracted from a collection of sales receipts,

determine that the document is a sales receipt based on the comparison of one or more features from the document to the receipt feature information, and

transmit the document to a cloud storage system for storage in a dedicated receipt storage location that is associated with the user.

20. The apparatus of claim 19, wherein the document is an attachment to an email message.

21. The apparatus of claim 19, wherein obtaining the document includes accessing one or more email messages and storing copies of one or more email attachments from the one or more email messages as the one or more documents.

22. The apparatus of claim 19, wherein the one or more documents are photographs.

23. The apparatus of claim 22, wherein obtaining the document includes accessing a collection of photographs that are associated with the user and storing copies of one or more photographs from the collection of photographs as the one or more documents.
