A method of predicting a release date of an item is provided. The method includes applying a first rule set to a first data set to create a second data set. The first rule set includes a rule that correlates a phrase with a date within a text string of the first data set. A second rule set is then applied to the second data set to create a third data set. The second rule set can include a rule that identifies a first item within a text string of the second data set and correlates the first item with the date such that the third data set has the first item that correlates with the date. A release date is then identified for the first item based on the date and a language pattern associated with the date.
