With the development of Internet e-commerce, shopping online has become very popular. Online stores have the advantage of having more items in their catalogue without worrying about shop constraints. In this scenario, recommendation systems are useful as they can help users in identifying items that they might be interested in. After shopping users usually provide feedback in the form review and ratings...
The graph-based algorithm for personalized recommendations mainly depends on the user-item model to construct a bipartite graph. We can provide recommendations by analyzing the bipartite graphs. However, for personalized videos recommendations, the classical recommendation algorithm based on graphs has low efficiency. Therefore, this paper gives an improved video recommendation algorithm that is based...
The relationship between internet and human life is becoming much more close than ever before. At the same time, Modern enterprise cooperate with each other in the form of technical collaboration is becoming a common mode of production and will be a crucial mode in the future. With the rapid development and popularization of internet, the scope of collaboration is more and more wide, such as across...
Nowadays, micro blogging platforms, which have strong influence in social network, have become major platforms for Internet public opinion formation and propagation. By means of hot topic detection and topic tendency research on micro blogging platforms, it will help government and companies in a timely manner to get social public opinion and popular investment spots. LDA is a commonly used method...
Mobile P2P content distribution is a promising solution to offload overwhelming growing mobile data traffic and improve the end-user experience. We study optimal distributed caching problem for mobile peer-to-peer data dissemination that leverages local cache of mobile nodes and their mobility. The problem accounts for finding the assignment of proportion of nodes to forward a set of data channels...
Event processing is a significant evolution in the field of information technology. Semantic link network (SLN) is a semantic data model for managing resources and their semantic relations. This paper proposes a two-layered SLN model for event processing: the matter level and the event level. The event SLN aims to record and manage the evolving process of the matter level. We propose a domain independent...
Multi-tiered storage systems today are integrating Solid State Disks (SSD) on top of traditional rotational hard disks for performance enhancement due to the significant IO improvements in SSD technology. It is widely recognized that automated data migration between SSD and HDD plays a critical role in effective integration of SSD into multi-tiered storage systems. Furthermore, effective data migration...
Innovative strategies for effective basin-scale salinity management have been developed in the Hunter River Basin of Australia and more recently in the San Joaquin River Basin of California. In both instances web-based stakeholder information dissemination has been a key to achieving a high level of stakeholder involvement and the formulation of effective decision support salinity management tools...
The traditional network simulator don't have the ability of simulation for the process of large-scale network security incidents outbreak, we designed a grid-based Internet worm behavior simulator which is consisted of foreground applications and background analog subsystems in parallel. It makes the most of the benefit of the grid computing capability, resource and task management. The experimental...
The Flume system is an implementation of decentralized information flow control (DIFC) at the operating system level. Prior work has shown Flume can be implemented as a practical extension to the Linux operating system, allowing real Web applications to achieve useful security guarantees. However, the question remains if the Flume system is actually secure. This paper compares Flume with other recent...
In multi-enterprises alliance for cooperatively designing and manufacturing product, all relevant data about the product is stored in the different product data management systems (PDMs) and databases respectively belonging to alliance members. In order to effectively integrating, storing and exchanging the decentralized product data among alliance partners, this article presents a distributed data...
It is necessary to analyze the anti-terrorism performance of Taiwanpsilas security system after September 11, 2001 attacks. We use three stage data envelopment analysis model that Fried et al. (2002) developed, getting intelligence performance of the Investigation Bureau of the Ministry of Justice, to discuss the ability of anti-terrorism in Taiwanpsilas national security system. Putting 10 outputs,...
Datasets of tens of gigabytes are becoming common in computational and experimental science. Providing remote visualization of these large datasets with adequate levels of quality and interactivity is an extremely challenging task, particularly for scientists who collaborate in widely distributed locations and their primary access to visualization resources is a desktop computer. This paper describes...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
