Extracting purchase-related information from electronic messages

A system, comprising a non-transitory memory storing processor-readable instructions, and a processor coupled to the memory, operable to execute the instructions, and based at least in part on the execution of the instructions operable to perform operations comprising:

• identifying purchase-related electronic messages in a collection of electronic messages transmitted between network nodes and stored in a first non-transitory networked data storage location;
• for each of respective ones of the identified purchase-related electronic messages ascertaining a respective template corresponding to the identified purchase-related, electronic message, wherein each template defines an ordered arrangement of unstructured free form text elements describing a respective electronic message body format;
• converting, by a processor, the templates into respective extraction parsers;
• extracting, by a processor, purchase-related information corresponding to a set of purchase-related data field types from unstructured free form text in body portions of respective ones of the identified purchase-related electronic messages, wherein the free form text in the body portions of the respective ones of the identified purchase-related electronic messages based on the unstructured free form text elements defined in the respective templates to output data corresponding to the set of purchase-related data field types, n herein the extracted purchase-related information relates to purchased products;
• storing the extracted purchase-related information as aggregated data in a second non-transitory networked data storage location, wherein the storing comprises aggregating the extracted purchase-related information in product purchased,
• for each of respective ones of the purchased products associated with a user, based on the purchase-related information that is extracted for the purchased product, retrieving additional purchase-related information for display in a predefined purchase history display specification but missing from the purchase-related information extracted for the purchased product, and augmenting the aggregated data with the retrieved purchased-related information;
• and
• in response to a request from a client network node associated with the user, transmitting data for displaying a view on the aggregated data on the client network node, wherein, in response to the request from the client network node associated with the user, the transmitting comprises transmitting to the client network node data for displaying, according to the predefined purchase history display specification, a view on extracted for the respective purchased products and the retrieved additional purchase-related information.

At least one non-transitory computer readable medium comprising instructions, which when executed by computer apparatus, cause the computer apparatus to perform operations comprising:

• identifying purchase-related electronic messages in a collection of electronic messages transmitted between network nodes and stored in a first non-transitory networked data storage location;
• for each of respective ones of the identified purchase-related electronic messages ascertaining a respective template corresponding to the identified purchase-related, electronic message, wherein each template defines an ordered arrangement of unstructured free form text elements describing a respective electronic message body format;
• converting, by a processor, the templates into respective extraction parsers;
• extracting, by a processor, purchase-related information corresponding to a set of purchase-related data field types from unstructured free form text in body portions of respective ones of the identified purchase-related electronic messages, wherein the extracting comprises, with the extraction parsers, respectively parsing the unstructured free form text in the body portions of the respective ones of the identified purchase-related electronic messages based on the unstructured free form text elements defined in the respective templates to output data corresponding to the set of purchase-related data field types, n herein the extracted purchase-related information relates to purchased products;
• storing the extracted purchase-related information as aggregated data in a second non-transitory networked data storage location, wherein the storing comprises aggregating the extracted purchase-related information in product purchased,
• for each of respective ones of the purchased products associated with a user, based on the purchase-related information that is extracted for the purchased product, retrieving additional purchase-related information for display in a predefined purchase history display specification but missing from the purchase-related information extracted for the purchased product, and augmenting the aggregated data with the retrieved purchased-related information,
• and
• in response to a request from a client network node associated with the user, transmitting data for displaying a view on the aggregated data on the client network node, wherein, in response to the request from the client network node associated with the user, the transmitting comprises transmitting to the client network node data for displaying, according to the predefined purchase history display specification, a view on the augmented aggregated data comprising purchase-related Information that is extracted for the respective purchased products and the retrieved additional purchase-related information.
