Abstract: The universal search engine, which is widely used now, has significantly improved the efficiency of retrieving information. According to CNNIC (China Internet Network Information Center) 26th Internet survey, the search takes up 76.30% for absolute advantage as a major way for users to obtain information from the Internet. Among almost all the surveys of using on the Internet in the world, search engine is second only to e-mail service. But with the growth of a wide range of information, these universal search engines can not meet people's needs either in retrieval precision or in retrieval efficiency when retrieving information on a subject or topic. That's because as long as the user enters the same keywords, the feedbacks of universal search engine are just the same. Universal search engine does not take the differences in interests and needs between different users, which often exist, into account. For example, dentists and ceramics enthusiasts would hold different concerns about the term "ceramic". In order to be more rapid, accurate and efficient in retrieving information on particular subject or theme, it is essential to develop information retrieval systems on specific areas, that is, the domain-specific search engine.

Abstract: IPv4 and IPv6 will coexist for a long time, due to ISPes’ inertia in the transition from IPv4 to IPv6. Domain Name System (DNS) is a very important functional unit in the Internet. This paper describres the hierarchy and operating process of IPv6 DNS, IPv6 DNS resolver, and presents the DNS transition from IPv4 to IPv6 in particular. We suggest two methods to implement DNS service during the transition period: DNS-Application Level Gateway (DNS-ALG) with Network Address Translation-Protocol Translation (NAT-PT), and dual stacks. And we also propose their respective operational principles. This paper is of valuable reference for network engineers to construct DNS in the transition phase.

Abstract: With the rapid development of computer and network technology, our everyday life is more and more influenced. In the information age it is an inevitable trend that consumer electronics will become more and more intelligentized and interconnected. Taking into account the characteristics of external network users’ access to a home networking, as well as the important role that the residential gateway plays in the interaction between external networks and home networking, this paper presents the idea of a unique access interface of the home networking. Furthermore, this paper designs and implements an IPv6-based UPnP real-time video and audio capture device, and the real-time audio/video stream captured is forwarded to external network users through the residential gateway. Other multimedia applications can be resolved in the same way.

Abstract: With the development of information society, the size and number of computer software increases sharply. This demands the quality of software higher and higher. Thus does software engineering management come into being, and is enriched, developed and perfected in engineering practice continually. In this paper, the author analyses the new theory's research background, meaning, and the applicant region. This paper sums up the experience of software engineering implementation in project developing, and points out the problems of software in software explore. From the character and existing problem in software, the author compares the usability of a lot of soft engineer process models in developing organization, points out the importance of the implantation in these organizations. In the end, this paper also gives its suggestions on implant principle, organization development, system building, staff training, and environment construction.

Abstract: In this paper, we focus on the risks and management of the information security, such as computer technology uncertainty,internet viruses and the information security soft outsourcing, then analyze the problems in internet bank information security, we conclude this paper by proposing some measures in controling the information insecurity of internet bank.

Abstract: With the rapid development of China's socialist economy, and information technology updating very quickly, while the masses begin to concern the sports, then their demanding for sports information is also increasing. Therefore, this paper based on the micro-blog effecting on the sports information dissemination as a starting point to think about the role of micro-blog on sports information, and offer some practical reference for China's sports information workers.

Abstract: As a new social networking media, Micro-blog is recognized by more and more people gradually, the orientation analysis of Micro-blog short text messages has become a hotspot in the field of data mining. At present, the research of Micro-blog orientation analysis mainly concentrate in the text, without considering the impact of other emotional factors. By analyzing and studying Sina Micro-blog, this paper added new words and emoticons in the basis of traditional emotional dictionary to construct special Micro-blog dictionary. Meanwhile, it analyzed rhetoric and sentence to improve the effect of orientation analysis. The experimental results showed that the method in Micro-blog orientation analysis obtained better performance.

Abstract: This paper analyzed to build the system used in ASP technology, network database technology, Web technology, database connectivity, VBScript and JavaScript, IIS technology. According to the system function modules to achieve an overall system design, detail the system architecture and functional modules for each function to be concrete implementation. As well as the detailed design of the system introduced various types of function modules of the implementation process. Finally from the data transmission encryption, improved MD5 password encryption, server configuration and other aspects of introducing the safety measures taken by the system, and system testing and operation have been summarized and analyzed in order to better refine and improve the future system.

Abstract: With the continuous development and popularization of computer network information technology, many colleges all have set up campus network. At present, campus network has been the important project in college base installation. However, information security issue of campus network would directly affect college to launch various pedagogical practices and refer to students’ individual privacy security issue. This paper has pointed out many safety loopholes existing in university campus network, and attempted to explore improvement measure and corresponding countermeasure of domestic university campus network information security.

Abstract: The market fish price is an important factor that affects the income of fishermen, so how to accurately analyze and predict the fish pricet o obtain huge profits has caught people's attention. As science advances, various price forecasting and analysis methods have come into being. How to build a prediction theories and models with relatively high success rate has been the study of many scholars over the years. With the development of artificial intelligence, neural networks have become an important tool of predicting and analyzing changes in market prices. Neural networks are important artificial intelligence technology, which have simple structures, but are able to solve complicated problems. They have strong applicability in predicting the mature index fluctuations in a short period. This paper considers some shortcomings and deficiencies the BP network prototype, which tries to use the wavelet Functions to replace the excitation function in the traditional BP algorithm on the basis of a network of neurons and then forms into WNN. We can verify the feasibility of WNN by perch price forecasts, and then this method is used in price forecasts of the three main fish of the Ulungur Lake Aquatic, to provide the basis for the aquatic base decision
