Image collector II: a system for gathering more than one thousand images from the Web for one keyword

We propose a system that enables us to gather more than one thousand images from the World Wide Web. The system is called Image Collector II. The Image Collector, which we proposed previously, can gather only several hundreds images. We made the two following improvements to extend the ability of our previous system in terms of the number of gathered images and their precision: (1) We extracted some words appearing with high frequency from all HTML files embedding output images in an initial image gathering, and using them as keywords, we made a second image gathering again. Through this, we obtained more than one thousand images for one keyword. (2) The more images we gathered, the more he precision of gathered images decreased. To raise the precision, we introduced word vectors of HTML files embedding images into the image selecting process in addition to image feature vectors.
