1. A method for obtaining representative text items from a plurality of text items in computer tasks, the method comprising: receiving first information indicative of a first computer task, the first information including a first plurality of text items; determining a genre associated with the first computer task; determining first representative location information of the genre based on a first frequency of occurrence of identical text associated with the first representative location information in the genre; for each of the first plurality of text items, assigning a first weight with a first magnitude, the first magnitude being determined based on the genre and the first representative location information; ranking the first plurality of text items based on the first weight assigned to each of the first plurality of text items to produce a first plurality of ranked text items; generating and storing first representative text items based on the first plurality of ranked text items; wherein the first computer task is a task other than entering search terms for the purpose of retrieving information; receiving second information indicative of a second computer task, the second computer task being different than the first computer task, the second information including a second plurality of text items, wherein the second plurality of text items is different than the first plurality of text items; determining second representative location information of the genre based on a second frequency of occurrence of identical text associated with the second representative location information; for each of the second plurality of text items, assigning a second weight with a second magnitude that is determined based on the genre and the second representative location information, the second magnitude being different than the first magnitude; ranking the second plurality of text items based on the second weight assigned to each of the second plurality of text items to produce a second plurality of ranked text items; and generating and storing second representative text items based on the second plurality of ranked text items; wherein the second computer task is a task other than entering search terms for the purpose of retrieving information.
