摘要
A keyword outputting apparatus includes a document receiving unit that receives documents in a specific time period. A keywords analyzing unit analyzes the documents for possible keywords. A keyword extracting unit calculates a score for each keyword and extracts the keywords in order of the score. A keyword-structure generating unit generates a keyword structure by classifying and stratifying each extracted keyword. A keyword outputting unit outputs the keywords in descending order of the score based on the keyword structure.
