PROBLEM TO BE SOLVED: To estimate the formation order of a pair of documents whose formation times are unspecified or uncertain. SOLUTION: The information processor 100 detects a keyword "ABC" included only in an article 1 that is a comparison object and a keyword "KYZ" included only in an article 2. Documents 1 and 2 including the keyword "ABC" and documents 3 and 4 including the keyword "XYZ" are searched from a document DB 110. The description time of the article is estimated from time data of the documents 1 and 2, and the description time of the article 2 is estimated from time data of the documents 3 and 4. The estimated description times of the article 1 and the article 2 are mutually compared to estimate the description order of the articles 1 and 2. COPYRIGHT: (C)2011,JPO&INPIT
