Claim:
1. A computer-implemented method for extracting pieces of text from a plurality of pieces of text, the method comprising the steps of: primarily evaluating a measure of positive expressions and a measure of negative expressions included in each of the plurality of pieces of text stored in a computer memory; secondarily evaluating each of the plurality of pieces of text using a processor on the basis of a plurality of evaluation functions, wherein each of the plurality of evaluation functions include, as variables, the measure of positive expressions and the measure of negative expressions; rating each of the plurality of pieces of text based on an evaluation score calculated by each of the plurality of evaluation functions and given to each of the pieces of text; extracting a piece of text having an evaluation result with a higher rating in preference to a piece of text having an evaluation result with a lower rating, wherein the individual evaluation results are based on the same evaluation function among the plurality of evaluation functions, wherein, in the primary evaluating step, the measure of positive expressions and the measure of negative expressions are primarily evaluated on the basis of a number of positive expressions and a number of negative expressions included in each of the pieces of text; and outputting each of the extracted pieces of text to a user on a display, wherein each of the extracted pieces of text is displayed for recognizing which evaluation function has given each of the extracted pieces of text a higher evaluation score.
