Abstract:
Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for extracting n-grams from a plurality of offers. Each offer includes a title and price. The n-grams are filtered by bid data and phrase. For each of the remaining n-gram, the plurality of offers are searched to provide offer search results. The n-grams are filtered by offers based upon the offer search results, and the filtered n-grams are provided. The filtered n-grams can be used as search hints, related searches, or advertising keywords.
