摘要

PURPOSE: A system for advertisements and a method thereof are provided to accurately classify search words by industry and to recommend appropriate search words to an advertiser, thereby improving advertisement effects. CONSTITUTION: A system for advertisements classifies keywords by industry based on purchase history of multiple advertiser terminals and generates a keyword list(S310). Then, the system for advertisements determines effectiveness of a keyword after defining the product of a term frequency(TF) score and an inverse document frequency(IDF) score as the effectiveness score(E)(S320). The system for advertisements generates pairings of all keywords which are included each industry(S330) and calculates a relativeness score of each of keyword pairings(S340). The system for advertisements recommends keywords to the advertiser terminals based on the generated keyword list, the effectiveness score, and the relativeness score of keyword pairings(S350). [Reference numerals] (S310) Determine industries classifying keywords; (S320) Determine the effectiveness of the keywords; (S330) Generate pairings of the keywords; (S340) Measure the relativeness of the keyword parings; (S350) Recommend keywords
