With the rapid development of new media, such as computer and Internet, extract valuable entity attribute information from Web text can be significant. Aiming at this problem, this paper puts forward SALmap, this model calls seed method at first, which will create common candidate attribute label sets by defining data format rules. Then we construct the mapping relationship between the attributes...
One of the most active threats we meet on the Internet is cyber-crime. Fast-flux is a kind of DNS technique used by botnets to hiding the malicious activities. In this paper we use data mining techniques to detect the fast-flux service network (FFSN) which is newly emerging and still not perceiving widely. From the data mining perspective, the detection of cyber-crime is viewed as kind of imbalanced...
Whether the category template is good or not is directly related to the precision of the information filtering in the system. And the classification system may often be changed. This article presents an algorithm which modifies the category template according to the feedback documents. Experimental results show that this algorithm can make category templates much closer to the real ones as soon as...
