Generating Keyword Lists Related to Topics Represented by an Array of Topic Records, for Use in Targeting Online Advertisements and Other Uses

摘要

A computer-implemented method of generating, from an array of topic records, an output array of keywords for use in targeting online advertisements related to topics represented by the array of topic records, includes obtaining the array of topic records in computer-readable form, determining a relevancy value for words and topics, classifying the topic vectors in the plurality of topic vectors into a high-volume class or a low-volume class, generating and storing an array of seed keywords derived by sampling from an embedded space, ranking the seed keywords to form an array of ranked keywords, updating the array of ranked keywords based on keyword cost-per-click data, iterating the ranking and updating at least once, and evaluating an optimization improvement value for an iteration.
