| Provides powerful support for the development of mobile Internet and communication technology for the information construction of modern society, people’s daily work, study and life has cannot do without network, communication between people exchanges are more dependent on the network. Through the network, the communication between people become more timely and convenient, especially for those with special requirements in the work of the people, network communication and even help them improve work efficiency. Can say, the network has become a part of our lives, but its importance has been paid more and more attention.After entering twenty-first Century, the Internet more rapid development, benefit people widely, people’s demand on the network to an all-time high, people are no longer confined to the simple communication, the Internet and other basic functions, application of electronic commerce, office automation, online banking, is it happened to turn the world upside down change people’s lives, the development of both people of all different demand and network technology, promote each other, bring about a new era of the development of human society.In the course of development of network application system, from the exclusive application fields at first has developed into today’s various groups, such as the network application never reached popularity today, such. For normal people, people to surf the Internet, online shopping, Internet communication process will have a very good experience, the full enjoyment of the network brought us convenience and enjoyment, but people of developing this kind of system is very easy to neglect some Internet will encounter a lot of problems, which we call them disabilities unity, including the disabled, special needs the perfect person, these people also need like normal people get all information and information from the Internet, but due tovarious reasons, such as the blind, network information cannot be obtained through the eyes, also can obtain various kinds of information on the Internet today bring to us.Now is a highly civilized and harmonious society, we should have the disorder love those on the body of the people, so that they can from the Internet can this information age occur easily, and quickly learn new things. At present, many scholars have carried out research work in this area, some foreign developed countries have even introduced some accessible government websites. Information accessibility is no longer a fresh topic, information accessibility is not just a technical work, it has more important social significance.Disabled are vulnerable groups are easy to be neglected by the society, the common people in social communication is often difficult to find the confidence, but the network can provide an effective way for the communication between them in the network they can speak freely, it is easy to find interest investment partner, opened a belongs to their private space for them. Moreover, this kind of crowd are generally difficult to participate in various social work, this has to a certain extent, let them feel inferior, then try to get as far away from the society, escape from the reality, construction of barrier free information industry can help them to participate in social work, play the unique role of them, can make contribution for the society, for the countries. All told, open an information barrier free information exchange platform is of great social significance and application value, contribute to the development and progress of our country and even the whole world information barrier free communication career.The research contents of this paper mainly include the following aspects:(a) this paper firstly illustrates the information barrier free construction background and significance, given the current implementation of the main technical means of information accessibility, and presents the research status at home and abroad. Points out the design principles of barrier free information navigation system, navigation design method. Describes the process of the construction of the barrier freeinformation exchange platform of information, the importance of design and optimization of site navigation.(b) by ASP.NET and Microsoft SQL Server database design and Realization of barrier free communication platform of an information, the platform including login module, the home page module, forum management module, the article module, the administrator management module function module, basically meet the various needs of people with disabilities access web. The development of the entire platform are social research based on the needs of various users, function realization, based on adequate human nature as the ultimate goal, running through the test, the system can meet the basic requirements of disabilities information browse, online shopping, online communication etc..(c) the barrier free information exchange platform has been implemented based on the information, this paper focuses on the optimization of disabilities through convenient site navigation Web access operation, the choice here through the data mining Web log way to update the site navigation, so that the user can priority access to the interested Webpage link.The main idea is to filter data through the web site of the Web log using the Apriori algorithm, can carry out mining IP user access Web information for each site in the data, find the user visited web pages by association rules, association rules can find more like attention to web content the user’s information, so that we can get a very good to make web content recommendation, let users can access to information of interest, to achieve barrier free access to the network for the disabled.The application of data mining techniques to analyze processing on the server logs, to find similar customer groups, relevant Web pages and frequent access path, its purpose is to find the user access patterns to access the Web system from the user’s behavior, in order to develop an information barrier free information exchange platform is the one big characteristic of this paper.Through this work, designed and developed a barrier free information exchange platform of an information, provides people information browsing, informationrelease, online chat and other obstacles can also be used to exchange the platform, the platform at the same time, the application of data mining technology makes the platform can be dynamically optimized web site navigation, can bring better access to people with disabilities in the platform in the process of experience. The implementation of the platform provides an effective solution for the information barrier free web development work. |
