Method and system for similarity modeling and identification

A system comprising:

• a processor, a network interface device, and a memory storing instructions executable by the processor to perform data processing activities comprising:
• receiving, via the network interface device, from a process involved in processing an open transaction on a Point-of-Sale (POS) terminal, data representative of at least one of products and services that are subjects of the open transaction;
• querying a recommendation engine that executes on the processor for at least one of product and service recommendations based on the received data representative of at least one of products and services that are subject of the open transaction, the recommendation engine executable on a computer processor to perform data processing comprising:
• identifying a certain number of similar customer prior purchase transactions of products and services to the products and services that are the subject of the open transaction;
• identifying at least one of products and services in the identified certain number of similar transactions that are not the subject of the present transaction based on a model generated, and regenerated on a periodic schedule, from historical transaction data stored in a database and based at least in part on data representative of one or both of product and service recommendations and reviews retrieved from at least one social media platform, the model including data linking relationships identified between products and services that are commonly purchased together and selected for inclusion therein by statistical analysis and recommendations generated by the recommendation engine based on statistical similarity measures, between products or services and customer attributes, and products and services of interest in particular geographies and during finite periods;
• and
• outputting the identified at least one of products and services in response to the query;
• receiving, in response to the query, at least one product or service recommendation;
• and
• providing, via the network interface device to the POS terminal, the at least one product recommendation to the process involved in processing the open transaction.
