In the theory of knowledge graphs, words are represented by word graphs. Sentences are to be represented by sentence graphs. This is called structural parsing. Under consideration of the semantic and syntactic features of natural language, both semantic and syntactic word graphs are formed, the latter expressing the function of word types like nouns, verbs,(More)
Traffic classification has been extensively examined in recent years, as it is widely used in network management, design, security, advertising and research. In the past few years, the traffic classification techniques have been evolved along with the development of Internet protocols and applications, and many approaches have been investigated, proposed(More)
Network traffic classification is critical to both network management and system security. However, existing traffic classification techniques become less effective as more P2P applications use proprietary protocols for delivery and encryption. Especially, current techniques usually focus on individual flows and do not consider all flows associated with an(More)
Many important network security areas, such as Intrusion Detection System and Next-Generation Firewall, leverage Traffic Classification techniques to reveal application-level protocols. Machine Learning algorithms give us the ability to identify encrypted or complicated traffic. However, classification accuracies of Machine Learning algorithms are always(More)
Protocol identification is critical for managing the network, from traffic classification to intrusion detection. However, the traditional protocol identification techniques have become less effective as more and more new network applications have adopted complex interaction and encrypted techniques in recent years. In this paper, we address behavior chains(More)
In this paper we present a new approach to extract relevant information by knowledge graphs from natural language text. We give a multiple level model based on knowledge graphs for describing template information, and investigate the concept of partial structural parsing. Moreover, we point out that expansion of concepts plays an important role in thinking,(More)
