Method of presenting excluded keyword categories in keyword suggestions

Abstract

A server can receive a seed keyword to generate additional keywords relevant to the seed keyword. The server can identify, using a semantic relationship graph, keyword categories. Each keyword can have a semantic distance from the seed keyword less than a threshold. The server can generate, for each keyword of the keyword categories, a keyword-seed affinity score based on a frequency of the keyword occurring with the seed keyword on an information resource. The server can determine, for each keyword category, a category-seed affinity score based on the keyword-seed affinity scores for each of keyword in the keyword category. The server can compare each category-seed affinity score a threshold. The server can transmit, for display, the keywords. One keyword category can be indicated as selected and another keyword category can be indicated as unselected based on the comparison.
