ABSTRACT:
A method, media and data structure for extraction of key-phrase-content pairs are provided. Query logs having user queries and corresponding web results are processed to generate a content-to-key phrase index that includes key phrases. The query logs are filtered and key phrases are derived from the queries included in the query logs. The key phrases are aggregated based on a repeated content pages in the web results. User behavior and metadata is used to assign scores for each key phrase. The scores are utilized to rank the key phrases. Among other things, the key phrases can be used for advertisement to content matching and content summarization.
