Content data searcher

Abstract

A content data searcher capable of adequately screening search objects even if the distribution of attribute values of contents which are search objects is uneven. The content data searcher comprises an impression value database containing an attribute value, a conversion table where a search word is related to a search word range which is the range of the attribute value corresponding to the search word, a range altering section for altering the relative relation between the distribution range of the attribute value and the search word range by altering the search word range read out of the conversion table, a receiving section for receiving the input of a search word and a search section for searching for content data corresponding to the search word received by the receiving section by searching from the attribute value included in the search word range corresponding to the search word in respect of the relative relation between the distribution range of the attribute value altered by the range altering section and the search word range.

Description

technical field [0001] The present invention relates to a content data retrieval device for retrieving content data. Background technique [0002] Nowadays, due to the network environment such as the Internet and the development of digital data compression technology, it is possible to obtain and listen to a large amount of content data such as music data or moving image data. Under such circumstances, techniques for retrieving content data desired by the user using search words indicating attributes such as characteristics and properties of the content have also been disclosed. [0003] In a conventional system for searching content data using a search term, for example, each content is assigned an attribute value indicating an attribute. In addition, a search term is converted into information indicating an attribute value range corresponding to the search term. Then, content data corresponding to attribute values ​​included in the attribute value range is output as a se...

However, this point has not been considered in previous music retrieval systems based on impression words

[0011] In this way, in the above-mentioned conventional impression word-based music retrieval system, when there is a bias in the distribution of the impression value of the music to be retrieved, the retrieval result is also biased, and it is impossible to output a retrieval result that understands the user's intention.

That is, it is impossible to provide users with the desired effect of restricting search objects
