Abstract
According to another aspect, a computer system is provided. The computer system includes a memory; at least one processor in data communication with the memory; an optical character recognition (OCR) component executable by the at least one processor; and a receipt parsing component executable by the at least processor. The receipt parsing component is configured to receive an image of a receipt; request execution of the OCR component to convert the image to text; identify a value of a vendor element in the text; identify values of additional elements in the text based on the value of the vendor element; and store the vendor elements and the additional elements in a data store.
Claims9
A method of parsing receipt information using a computer system, the method comprising:
- receiving, by the computer system, an image of a receipt;
- requesting execution of an optical character recognition (OCR) component to convert the image to text;
- accessing a plurality of regular expressions associated with a plurality of vendor elements;
- identifying a string of characters in the text that match a character pattern specified by at least one regular expression of the plurality of regular expressions, wherein the at least one regular expression includes metacharacters;
- capturing a value of a vendor element from the text, wherein the value of the vendor element comprises the string of characters that match the character pattern;
- accessing reference data specifying additional elements associated with the value of the vendor element and information to identify values of the additional elements;
- capturing the values of the additional elements in the text based on the reference data, wherein the act of capturing the values includes:
- searching the text for regular expressions associated with the additional elements;
- and
- locating the values of the additional elements using receipt format information associated with the additional elements that specifies locations for the values relative to the regular expressions;
- and
- storing the value of the vendor element and the values of the additional elements in a data store.

A non-transitory computer readable medium storing sequences of computer executable instructions to implement a method for parsing receipt information, the sequences of instructions including instructions to:
- receive an image of a receipt;
- request execution of an optical character recognition (OCR) component to convert the image to text;
- access a plurality of regular expressions associated with a plurality of vendor elements;
- identify a string of characters in the text that match a character pattern specified by at least one regular expression of the plurality of regular expressions, wherein the at least one regular expression includes metacharacters;
- capture a value of a vendor element from the text, wherein the value of the vendor element comprises the string of characters that match the character pattern;
- access reference data specifying additional elements associated with the value of the vendor element and information to identify values of the additional elements;
- capture the values of the additional elements in the text based on the reference data, wherein capturing the values of the additional elements includes:
- searching the text for regular expressions associated with the additional elements;
- and
- locating the values of the additional elements using receipt format information associated with the additional elements that specifies locations for the values relative to the regular expressions;
- and
- store the value of the vendor element and the values of the additional elements in a data store.

- store the value of the vendor element and the values of the additional elements in a data store;
- wherein the receipt parsing component is further configured to:
- identify a telephone number on the receipt and trigger a reverse telephone number lookup service to capture information on the vendor.
