abstract = {This paper explores identifying illegal domains on the Tor darknet based on their visual content. After crawling 500 hidden services and categorizing their images into five illegal categories, a classifier was trained using the Bag of Visual Words (BoVW) model with SIFT descriptors. Since SIFT only works with grayscale images, color-SIFT variants (HSV-SIFT, RGB-SIFT) were tested. The results show that color-SIFT descriptors, particularly HSV-SIFT, outperform traditional SIFT, achieving an accuracy of 59.44%, compared to SIFT's 57.52%.},

This paper explores automatic text summarization applied to illegal content extracted from onion websites on the Tor network. The goals include evaluating the feasibility of summarizing such content, comparing summarization methods, and introducing a new dataset called "OWIDSumm," which contains manually curated summaries for 60 documents related to illicit services.
