A method for processing information, comprising the steps of:

• extracting a plurality of words serving as keywords of content from content information that describes the content;
• searching a property dictionary containing the properties of the plurality of words for the properties of the plurality of words;
• determining whether each of the properties of a target word to be processed and selected from among the words serving as keywords matches any of the different words other than the target word among the words serving as keywords or determining whether each of the properties of a target word matches any of the properties of the different words;
• and
• determining a representative property of the target word of the content on the basis of a match count between the properties of the target word and the different words or the properties of the different words determined by the property determining means.

A computer-readable program comprising program code for causing a computer to execute the processing steps of:

• extracting a plurality of words serving as keywords of content from content information that describes the content;
• searching a property dictionary containing the properties of the plurality of words for the properties of the plurality of words;
• determining whether each of the properties of a target word to be processed and selected from among the words serving as keywords matches any of the different words other than the target word among the words serving as keywords or determining whether each of the properties of a target word matches any of the properties of the different words;
• and
• determining a representative property of the target word of the content on the basis of a match count between the properties of the target word and the different words or the properties of the different words determined by the property determining means.
