摘要

PROBLEM TO BE SOLVED: To provide an information processor for presenting information related to a retrieval keyword.

SOLUTION: An information processor includes: a setting unit for setting a retrieval character string; a retrieval unit for retrieving information including the set retrieval character string; and a determination unit for extracting a co-occurring character string candidate group in which partial character strings appearing only as a part of other partial character strings are excluded from all the partial character strings appearing in multiple pieces of the information obtained as a retrieval result and determining a co-occurring character string out of the co-occurring character string candidate group on the basis of the extracted co-occurring character string candidate group and types of characters used in characters before and after the candidate group. The present disclosure can be applied to a retrieval device, for example.
