Abstract
A system and method for detecting preference expressions indicating evaluators' likes and dislikes of a product from evaluations of the product and stores text describing evaluation of the product in association with an attribute of the text. The method extracts an evaluating expression describing evaluation of the specific object from each of the texts, determines whether the extracted evaluating expression has positive or negative polarity, where the positive indicates favorable evaluation and the negative indicates unfavorable evaluation. The system inputs a text attribute that is designated as an object for detecting the preference expression and detects an evaluating expression, which is detected from a text having an input attribute from the extracted evaluating expressions as one of the preference expressions and outputs the preference expressions in association with a frequency of the preference expressions being determined to have the positive or negative polarity in the text having the attribute.
