A Web Page Classifier Library Based on Random Image Content Analysis Using Deep Learning
This work addresses webpage categorization for content filtering, but it is incremental as it applies existing methods to a specific domain.
The authors tackled webpage classification by analyzing images with a deep learning-based random forest model, achieving classification of weapon-related webpages on a dataset of 3859 sites using a probability threshold method.
In this paper, we present a methodology and the corresponding Python library 1 for the classification of webpages. Our method retrieves a fixed number of images from a given webpage, and based on them classifies the webpage into a set of established classes with a given probability. The library trains a random forest model build upon the features extracted from images by a pre-trained deep network. The implementation is tested by recognizing weapon class webpages in a curated list of 3859 websites. The results show that the best method of classifying a webpage into the studies classes is to assign the class according to the maximum probability of any image belonging to this (weapon) class being above the threshold, across all the retrieved images. Further research explores the possibilities for the developed methodology to also apply in image classification for healthcare applications.
