Hitachi Released New Ranking Feature to Search By Drawing at Its Similar Image Search Engine ‘GazoPa’

Hitachi, Ltd. (NYSE:HIT) (TOKYO:6501) announced today that a ranking feature to search by drawing was released for its similar image search engine GazoPa.

Search by drawing is one of the most popular features at GazoPa. Users can search for similar pictures, photos and video thumbnails by their drawings. The new 'Ranking' feature enables users to unlock its drawings to public so that other users can rate them. Other users rate not quality of drawings but quality of its search results. The number of stars indicates their evaluation score. The most popular and the latest drawings are shown separately.

Users who upload their drawing can receive responses from other users. Other users can express their feelings to search results by drawings. Search itself seems to be one-way communication, but this new feature will enable its users to implement interactive communications.

There are other Websites that enable users to rate the quality of drawings, but the ability to evaluate the search result differentiates GazoPa from other services. This feature is one of the applications that similar image search is used.

This new feature is the first step that Hitachi has released to provide social and interactive functions of GazoPa. In the future, Hitachi plans to release additional new features that use their strength.
