Document Type and Number:
WIPO Patent Application WO/2012/115254
Kind Code:
A1
Abstract:
A search server (10) is provided with an extractor (15b) for extracting a search target corresponding to search conditions on the basis of profile data, and a transmitter (15c) for transmitting the extracted search target to a user terminal (T). The search conditions include a first occurrence frequency for each of one or more designation topics designated by the user in relation to a first designation period; and a second occurrence frequency for each of the designation topics in relation to a second designation period, which is after the first designation period. The extractor (15b) extracts a search target in which the occurrence frequency for each of the designation topics obtained from profile data in relation to a first search target period is identical or similar to the first occurrence frequency, and in which the occurrence frequency for each of the designation topics obtained from the profile data in relation to a second search target period, which is after the first search target period, is identical or similar to the second occurrence frequency.
