Phishing attack has become the most dangerous form of fraud to hit online and mobile businesses. In this paper, we reveal some new aspects of the common features that appear in the phishing URLs, and introduce a statistical machine learning classifier to detect the phishing sites which relies on these selected features. Unlike previous studies, we do not utilize a single model for different regions...
Product feature and opinion word extraction is very important for fine granular sentiment analysis. In this paper, we leverage large-scale unlabeled data for joint extraction of feature and opinion words under a knowledge poor setting, in which only a few feature-opinion pairs are utilized as weak supervision. Our major contributions are two-fold: first, we propose a data-driven approach to represent...
Objective To study the functional change of peripheral nerve after repaired in different size by small gap briding (the proximal end is smaller than the distal in size), compared with epineurium suture in the same size. To explore the effect of functional reserve of peripheral nerves and the best situation for the reserve of nerve functional. Methods 10 Wistar rats served as the donors of arteris...
Seam measuring of complex tight butt joint without misalignment for laser welding is a challenging problem. The allowable seam gap width and misalignment in laser welding process are less than 0.1 mm for thin sheet around 2 mm thickness. Current measuring methods or sensors can not stably and accurately extract 3D seam position and seam gap width, due to narrow seam gap and too little misalignment...
