A method for updating prices for phrases may begin by receiving, at a computing device, a real-time data feed comprising a plurality of messages. The method may continue by detecting, by the computing device, a topic associated with a message in the plurality of messages using natural language processing. The topic may indicate the subject of the message. The method may continue by calculating, by the computing device, a score for the topic using temporal data associated with the message. The score may indicate the popularity of the topic. The method may continue by extracting, by the computing device, a keyword phrase from the topic. The method may conclude by determining, by the computing device, a price associated with the keyword phrase using the score.
