Abstract

When a user searches the Web for information about a target object by submitting a keyword-based query to such a conventional Web search engine as Google, the precision and recall of the search results depend a great deal on whether or not s/he has known exactly the concrete name of the target object. However, the user does not always know the concrete name of any target object that s/he has encountered in the real world and wanted information about. In this paper, we propose an application system of Object-Name Search that helps her/him to identify the concrete name of the target object by such ambiguous features as its class-name, visual appearance and spatio-temporal information. When the user inputs a class-name, visual appearance and/or real-world context descriptions, our system returns not only concrete object-names ranked by her/his specification but also their typical images, visual appearance and spatio-temporal descriptions. And then the user can also modify her/his original specification repeatedly by using their typical features as a useful reference.
