A Localness-Filter for Searched Web Pages
With the spreading of the Internet, information about our daily life and our residential region is becoming to be more and more active on the WWW (World Wide Web). That’s to say, there are a lot of Web pages, whose content is ‘local’ and may only interest residents of a narrow region. The conventional information retrieval systems and search engines, such as Google, Yahoo, etc., are very useful to help users finding interesting information. However, it’s not yet easy to find or exclude ‘local’ information about our daily life and residential region. In this paper, we propose a localness-filter for searched Web pages, which can discover and exclude information about our daily life and residential region from the searched Web pages. We compute the localness degree of a Web page by 1) estimating its region dependence: the frequency of geographical words and the content coverage of this Web page, and 2) estimating the ubiquitousness of its topic: in other words, we estimate if it is usual information that appears everyday and everywhere in our daily life.
