Abstract: As one of the typical social media categories, microblogs have become the hot vehicle for online communication and interaction since 2006. Not only individuals, but also organizations are all fascinated to open their own microblogs. Government microblogs launched by Chinese governmental agencies have showed the blowout development since 2011. These microblogs devote to release public information, guide public opinions, promote government and place images and fulfill administrative transparency. This paper will introduce the development of government microblogs in China and articulate suggestions for effective utilization of government microblogs as a vehicle for e-government.

Abstract: Online shopping reviews provide valuable information for customers to compare the quality of products, and many other aspects of future purchases. People increasingly rely on information from E-commerce reviews. Product reviews is an important determinant of potential customers’ buying choices. However, spammers are joining this community to try to mislead consumers by writing fake or unfair reviews to confuse the consumers. Fake product review detection makes an attempt to detect fake reviews and remove them to restore the truthful ones for readers. To the best of our knowledge, there is still less published study on this problem. In this paper, we make a survey and an attempt to give a brief overview on review spam. The related work of fake product review detection is presented including web spam and spam email. Then some methods to detect review spam are introduced and summarized. The trend of review spam detection is concluded finally.

Abstract: This paper presents a Multi-choice of E-Business Model for best practice within E-Business based upon the literature to define the logic of a business system for creating value & revenue streams in the Internet era. The objectives of this paper is to develop promote and coordinate the practice matrix of electronic business. It is composed of three main Perspectives, which are Strategy (Value-added), Business model (Classification), and Business process (Revenue streams). Finally, we show that it makes sense of E-business strategy to choose the e-BM, which was under the matrix of BM to compare value-added aspect with revenue streams.

Abstract: In this paper, the proxy blind multi-signature scheme proposed by Hu was analyzed, and we show that the scheme is not secure against the attack which the signature requester can tamper with the proxy warrant. In order to overcome the defect, we improve the proxy blind multi-signature scheme. The improved scheme can resist the attack, and meet integrity, unforgeability, verifiability, strong blind. This improved scheme is more secure and practicable, and suitable for electronic commerce.

Abstract: Nowadays, the electronic means of communication have an unprecedented impact in the way of projects are developed. The electronic information –due to its nature– has now a more democratic approach of operation, plummeting the power of the great companies and governments. With the creation of the web 2.0, the common users of Internet have now a huge number of communication tools, which allow them to know –in an immediate, measured and effective way– what they or others think or believe. So, the object that has changed as a main channel is the operation by Internet. This current and simple –for many– phenomena, has a deep implication in the way of replanting the new paradigms with a global impact in productive projects as a commerce target.

This paper has chosen three data backup and recovery system to introduce and analyze according to the current basic data backup and recovery system model, designed to make the reader have a clear and thorough understanding of the current disaster recovery system that has already established.

Abstract: With the development of computer technology and network, e-Auctions are widely applied in the field of engineering technology. How to use the computer technology and network to optimize the models of multi-object e-auctions is a hot topic. Regarding the e-auction as a background, this paper presents many widespread theoretical and applied problems, and summarizes and reviews the main conclusions and progress of existing studies related to the computer technology and network in the e-auctions, and then gives several new research topics to e-auctions. It tries to promote the applications of e-auction theories in real engineering technology problems.

Abstract: In recent years the number of APP users rapid growth, so the research on APP user’s satisfaction is particularly important.This paper makes analysis and research on the evaluation method of APP user’s satisfaction, in view of the different influence factors of users in the use of the APP, we put forward the evaluation index of APP user’s satisfaction set, and used AHP to determine the weight of evaluation index, finally we get the asessment for the APP user’s satisfaction situation through the fuzzy mathematics comprehensive evaluation model.In the end of the paper, we can get a conclusion that the method is objectivity, practicability and accuracy.
