The query translation of Out of Vocabulary (OOV) is one of the key factors that affect the performance of Cross-Language Information Retrieval (CLIR). Based on Wikipedia data structure and language features, the paper divides translation environment into target-existence and target-deficit environment. To overcome the difficulty of translation mining in the target-deficit environment, the frequency...
Network society is a new social formation promoted by information technologies which mainly refer to computer and Internet technologies. It could be suitable to apply the fundamental principle of ecology to the research of network society as an ecosystem, named network social-ecological system. Network social-ecological system has intricate formation and structure and is in a constant change. This...
A major challenge that researchers face in studying denial of service (DoS) attacks is the size of the network to be investigated. A typical DoS attack usually takes place over a large portion of the Internet and involves a considerable number of hosts. This can be intractable for testbed experimentation, and even simulation. Therefore, it is important to simplify a network scenario with DoS attacks...
Considering that personalization recommendation systems based on association rules suffer from some limitations that a lot of time is spent on matching current user session with all discovered patterns in patterns database, authors propose a new approach to build personalization recommendation system based on access sequential patterns discovered form usage data and highly compressed into a tree structure...
It is worthwhile to analyze user's access patterns by capturing maximal access sequences from Web usage data in practice. Web access pattern tree (WAP-tree) stores the highly compressed access sequences, and mining frequent access sequences based on WAP-tree needs to scan transaction database only twice. However, producing conditional WAP-tree repeatedly in the algorithm influences the efficiency...
