A relocator matching method executed by a computer, the relocator matching method comprising:

• displaying, by the computer on a web screen of the computer, a plurality of inquiries to a respondent to collect answers corresponding the plurality of inquiries from the respondent;
• for each inquiry of the plurality of inquiries including a plurality of options that matches what a relocator wants, based on a number of times a preference chosen and a log of answers of the respondent in past, specifying, by the computer, a matching option indicating a trend of choosing an option corresponding to answers of the respondent from the plurality of options to be represented to the respondent;

• and
• in response to a result of the determining that the respondent reaches the preference-reached mode, transmitting, by the computer to the respondent, an inquiry including options included in the matching option, wherein contents of the options included in the inquiry being changed depend on whether the respondent reaches the preference-reached mode in the determining;
