System and method for presenting targeted content

Abstract

A computer-implemented system for presenting targeted content is provided. The system comprises a processor configured to obtain user permission and access profile attributes and friend attributes from a social-network interface, generate, for each person, an identifier from attributes including name, date-of-birth, and location, and store, keyed by the identifier, user search and browsing actions and external records ingested via a distributed data pipeline. Further, the processor is configured to store conversational dialogues as questions and answers using sequence-to-sequence algorithms, or as parent nodes and responses as child nodes of a graph formed on an inverted index. Further, the processor is configured to determine a purchase-funnel stage for the identifier using a classifier trained on search keywords, domains, and page categories, select an advertisement ranked based on revenue, user preference, and context, and generate multi-stage advertisement messages corresponding to discovery, consideration, and action.
