Abstract

Disclosed herein are system, method, and computer program product embodiments for rapid identification and access to relevant regulatory documents. A data model relating regulatory mandates and requirements to citations appearing within an enforcement document is used to rapidly access specific citations within an enforcement document. In the case of image-based enforcement documents, the originality of these documents is preserved while allowing a user to see where the relevant citations appear in the document images. The relevant citations are further compared to business policies to identify potential impacts of regulatory mandates and requirements.

First claim

What is claimed is:

1. A method, comprising:
extracting, by at least one processor, a citation from a document;
parsing, by the at least one processor, the extracted citation into first one or more sub-citations;
comparing, by the at least one processor, the first one or more sub-citations to second one or more sub-citations of a reference citation identified in a business policy document responsive to a business requirement, wherein the comparing identifies a relationship between the citation and the business policy document based on a level of matching between the first one or more sub-citations and the second one or more sub-citations;
mapping, by the at least one processor and in response to identifying the relationship, the first one or more sub-citations to one or more policies in the business policy document; and
classifying, by the at least one processor, the document as relevant to the business policy document based on the level of matching between the first one or more sub-citations and the second one or more sub-citations.

2. The method of claim 1 , wherein extracting the citation from the document comprises:
comparing text in the document to a citation key; and
in response to identifying a first string of characters from the text that matches the citation key, extracting a second string of characters comprising the first string of characters, a third string of characters located in the text immediately before the first string and a fourth string of characters located in the text immediately after the first string.

3. The method of claim 1 , wherein extracting the citation from the document comprises:
comparing text in the document to a citation key, wherein the citation key comprises a first string of characters; and
in response to identifying a second string of characters from the text that differs from the citation key by at least one character and having a matching metric greater than a threshold, marking the second string of characters as a citation extraction error.

4. The method of claim 1 , wherein:
the first one or more sub-citations comprises a first root and a first subsection;
the second one or more sub-citations comprises a second root and a second subsection; and
classifying the document based on the level of matching between the first one or more sub-citations and the second one or more sub-citations comprises:
in response to the first one or more sub-citations matching the second one or more sub-citations, classifying the document as an exact match for the business policy document;
in response to the first root matching the second root and the first subsection matching the second subsection, classifying the document as a subsection match for the business policy document;
in response to the first root matching the second root and the first subsection being different than the second subsection, classifying the document as a root match for the business policy document; and
in response to the first root being different than the second root, classifying the document as a non-match for the business policy document.

5. The method of claim 1 , further comprising:
extracting, by the at least one processor, one or more fine amounts from the document, wherein the one or more fine values correspond to the citation;
removing, by the at least one processor, each duplicate fine amount from the one or more fine amounts to form a set of fine amounts; and
combining, by the at least one processor, the set of fine amounts into a total fine amount corresponding to the citation.

6. The method of claim 1 , further comprising:
extracting, by the at least one processor, a fine amount from the document, wherein the fine amount comprises a number prefix and a word suffix; and
combining, by the at least one processor, the number prefix and the word suffix to form a number amount for the fine amount.

7. The method of claim 1 , further comprising:
determining, by the at least one processor, a score describing an impact of the document on a business based on the business policy document, the citation, the classification of the document, and text in the document related to the citation; and
in response to the score being greater than a threshold, presenting, by the at least one processor, a summary of the impact of the document on the business, wherein the summary comprises one or more of a link to the business policy document, the citation, a link to a reference document described by the citation, a classification of the document, a link to the document, or the score.

8. The method of claim 7 , further comprising:
extracting, by the at least one processor, a total fine amount corresponding to the citation,
wherein determining the score describing the impact of the document on the business is further based on the total fine amount; and
wherein the summary further comprises the total fine amount.

9. A system, comprising:
one or more processors;
memory communicatively coupled to the one or more processors, the memory storing instructions which, when executed by the one or more processors, cause the one or more processors to:
extract a citation from a document;
parse the extracted citation into first one or more sub-citations;
compare the first one or more sub-citations to second one or more sub-citations of a reference citation identified in a business policy document responsive to a business requirement, wherein the comparing identifies a relationship between the citation and the business policy document based on a level of matching between the first one or more sub-citations and the second one or more sub-citations;
map, in response to identifying the relationship, the first one or more sub-citations to one or more policies in the business policy document; and
classify the document as relevant to the business policy document based on the first one or more sub-citations and the second one or more sub-citations.

10. The system of claim 9 , wherein the instructions are further configured to extract the citation from the document by:
comparing text in the document to a citation key; and
in response to identifying a first string of characters from the text that matches the citation key, extracting a second string of characters comprising the first string of characters, a third string of characters located in the text immediately before the first string and a fourth string of characters located in the text immediately after the first string.

11. The system of claim 9 , wherein the instructions are further configured to extract the citation from the document by:
comparing text in the document to a citation key, wherein the citation key comprises a first string of characters; and
in response to identifying a second string of characters from the text that differs from the citation key by at least one character and having a matching metric greater than a threshold, marking the second string of characters as a citation extraction error.

12. The system of claim 9 , wherein:
the first one or more sub-citations comprises a first root and a first subsection;
the second one or more sub-citations comprises a second root and a second subsection; and
the instructions are further configured to classify the document based on the level of matching between the first one or more sub-citations and the second one or more sub-citations by:
in response to the first one or more sub-citations matching the second one or more sub-citations, classifying the document as an exact match for the business policy document;
in response to the first root matching the second root and the first subsection matching the second subsection, classifying the document as
