Title:
SEARCH SYSTEM, CONTROL METHOD FOR SAME, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/108746
Kind Code:
A1
Abstract:
In order to search for similar content, prior information related to content is required. To this end, this similarity search system restricts the types of content which are treated as search conditions. Therefore, a search system is desired that is capable of treating even unknown binary data as an object of a similarity search. In this search system, an index registration server which registers a pseudo-random number based on first content data as an index term, and a similarity search server are connected across a network; wherein the similarity search server is provided with a search-external-interface unit which acquires second content data, a search chunk data generation unit which partitions the second content data in order to generate a search chunk data string, a search-pseudo-random number unit which calculates a pseudo-random number on the basis of each chunk data unit within the search chunk data string, and a similarity search unit which extracts all index terms which satisfy similarity criteria with the pseudo-random number as a search term.
