1. A non-transitory computer-readable storage medium for storing an acronym-management program for causing a computer to function as: a list-managing device that manages an acronym list in which an acronym, an expanded form corresponding to the acronym, and the frequency with which the acronym is used to refer to the expanded form are correlated; an acronym-extracting device that extracts the acronym from a plurality of list-updating references for updating the acronym list; an expanded-form-extracting device that extracts, from a designated list-updating-reference out of the plurality of list-updating-references, a candidate for the expanded form corresponding to the acronym extracted from the designated list-updating reference from which the acronym has been extracted; and the list-managing device that increases, in the acronym list, the frequency correlated with the acronym and the expanded form when the likelihood of the acronym extracted from the list-updating reference being used in the list-updating reference to refer to the extracted expanded-form candidate reaches or exceeds a specific level; and the program causing the computer to function as a category-determining device that extracts a category given in a corpus for each of N words occurring most frequently in the designated list-updating reference, and determines that a category extracted most often is a category of the designated list-updating reference; the acronym, the expanded form, and the category being correlated in the acronym list; and the program causing the computer to function as the list-managing device that increases, in the list, the frequency as correlated with the acronym, the expanded form, and the category when the likelihood of the acronym extracted from the list-updating reference being used in the list-updating reference to refer to the extracted expanded-form candidate reaches or exceeds a specific level.

The non-transitory computer-readable storage medium of claim 1 , the program causing the computer to function as: an expanded-display device that displays the expanded form corresponding to the acronym; the acronym-extracting device that extracts the acronym from a designated reference; and the expanded-display device that displays the expanded form correlated in the acronym list with the acronym extracted from the designated reference along with a degree of accuracy based on the frequency; the degree of accuracy being a value correlated with the acronym and the expanded form in the acronym list.
