Abstract
A content evaluation device includes: extraction means (11) for extracting a feature amount quantitatively characterizing a content for each of contents; interpolation means (22) for interpolating distribution of feature amounts associated with contents having a history affirmatively or negatively evaluated for one search word among the contents; and creation means (24) for creating a score curve for correlating a score to a feature amount. The content evaluation device further includes calculation means (25) for calculating a score according to the score curve thus created. This enables evaluation of matching degree.
