The web contains an abundance of semi-structured information, but not all the information is useful for users, it always contains so many noises such as the advertisement, navigation information, and so on. Identifying which parts of the web page contain target content and classify them into right category (such as title, author, time, content and so on) become a significant problem that must be solved...
This paper novel proposes a flexible RFID based production process management system architecture with the service oriented architecture technology. The system managers can add a new function or a new production process by the visual interface of our architecture. This architecture is used to construct a visualization system prototype which can be used to manage laundry process effectively by using...
For TCP/IP Agreement has certain security bugs, the hacker catches the opportunity to attack the Network. On the basis of the analysis of the TCP/IP Agreement's vulnerability, the article has further analyzed the vulnerability of the Transport Layer Agreement, and discussed the security and the promotion method of TCP/IP Agreement's transport layer.
As a part of Cloud computing, Software as a Service (SaaS) enables users to cut their costs by outsourcing software as a service on-demand, in which both computation and storage are handled on server-side. However, data must be decrypted into memory when performing the computation, even though they can be encrypted during storage and transmission. In this case, the privileged administrators of SaaS...
The geographical knowledge-informed digital gazetteer service (KIDGS) is a standard web service that provides unified XML-based access interfaces for various applications. In order to solve the problem of the raising data storage crabbed from millions of web pages and increasing query efficiency requirements for different levels of requests, we analyze the characteristics of cloud computing application...
Geographical information becomes a kind of very important attribute for web documents, considering the fact that a large proportion of documents on the web contain geographical information. GIR (Geographical information retrieval) systems can identify those geographical information and extract the geographical focus in the documents automatically, hence supporting geo-related queries for information...
This paper discusses problems on scale-free network traffic, with the bandwidth considered as the delivering ability of links. Moreover, the traffic model of scale-free network is established, with the fixed bandwidth, which means the delivering ability of each link as a constant in the network. For better understanding traffic dynamic in real systems, the effects of bandwidth on the packet delivering...
This paper studies the web wrapper generation for web pages of forum, blog and news web sites. While more and more web pages are dynamically generated using a common template populated with data from databases. This paper proposes a novel method that uses tree alignment and transfer learning method to generate the wrapper from this kind of web pages. We present a new tree alignment algorithm to find...
With more and more reviews on the Web, browsing through a mass of the related reviews becomes a heavy work. How to effectively analyzing and organizing these reviews attracts more attention. This paper pursues on the analysis of product reviews. It focuses on the product features that customer commented on and also whether their opinions are positive or negative. Different from the traditional method,...
A weighted evolving model of scale-free network is proposed. Our model has been inspired by the weighted network model proposed by Alain Barrat etal. (BBV for shot), which consider the emergences of new links according to Triad Formation and strength preferential selection mechanism. Interactions more easily occur between neighbors with high-strength in our model. The effects of Triad Formation on...
Scale-out approach, in contrast to scale-up approach (exploring increasing performance by utilizing more powerful shared-memory servers), refers to deployment of applications on a large number of small, inexpensive, but tightly packaged and tightly interconnected servers. Recently, there has been an increasing interest in scale-out approach. The purpose of this study is to discover advantages or disadvantages...
