We have discover two problems in the experiment.
The filtering of political topics
According to the Chinese Dumplings Poisons' result, why some of the political topics are not displayed in some districts. Should search engine censor search results? However it is possible that search engines may remove search results because of the local laws. The government does not want the netizens know more about some of the political topics.
For example Tiananmen Square, results in many text references and images of the Chinese government crackdown on protesters in 1989 on the U.S. search site, but mainly hotel and tourist information on the Chinese version.
It is obvious that the government want to hide some political topics. They want to repress freedom of speech. Also they want to control the messages in the Internet in order to prevent unapproved reformist. They can prevent their netizens from discovering more about past.
In Tiananmen Square's example, the government don't want the people know more about Tiananmen Square Protests' in 1989, so the government filter all the results. But it means that does is a good way for the government to block these political topics?
These actions may destroy the freedom of academic. If the government finds any sensitive and political topics, then they block these issues in order to prevent people from discussing the topic. It is not fair because some of the districts cannot receive the same results.
For example in China, Chinese cannot access any news about Tiananmen Square Protests' in 1989, but other districts people can read the news. Does it fair? Search engine should not censor search results. Everyone search the results should be the same whatever they live in different countries. It should be fair for everyone, so search engine should not filter some of the results. They should display the same results in different districts.
According to these results we found that it is really unfair to these user-based websites to have a big different gap in their ranking priorities. To explain this phenomenon, the ranking priorities of a website can be boosted by paying a sum of money to the search engine and its priority will also be boosted positively. Since the ranking priority is not shown according to its popularity but the money contributions. Some websites start to use soft wares to raise their ranking priority and this tell us why there are quite a different ranges ranking results shown by different search engine. Does it fair to other companies? Pay more money to increase their ranking in order to attract more netizens to visit their website. Is it a fair competition? Everything should be fair in search engine.
Beside the experimentAlso we have discoverd other problems. You can check it out below
Search Engine is Over-Powerful
Did you try to type your name in search engine and see the results? If yes, what did you see? We have tried to type our name in search engine; we can see a lot of information about us. For example, we could see our online photo album, online journal, even the forum we have visited recently. It seems that nowadays search engine is very powerful. If you want to find a person, you can type his/her name, then you may find a lot of information about him/her, for example you may find his/her email address, journal etc.
You don t need to ask your friends. A search engine can help you to find out his/her information. But it will turn up another problems; some people may steal your personal information to do something illegally. For example, they can type your name and find your personal information and use your personal information to apply for credit card, services and loan etc, without your permission. In America, it is very common. It seems that this problem is very serious. So netizens should be careful. You should not disclose your personal information in the Internet.
Also some of the search engines may record your search results and then next time when you want to search the same things, you don t need to search it again. It seems that is it very convenient but it may turn up a problem, some search engine may know more about your information. The search engine will analysis your search results and record which website do you visit most, then search engine may get more about your information. Then some search engine may sell your information to some companies to get benefits. For example, you always search mobile phone, and then the search engine may analysis that you like mobile phone very much, so they will sell your information to some mobile phone companies. Finally when you search mobile phone again, some mobile phones companies' websites or advertisement will be displayed immediately.
Is it a good function? When you are using search engine, you will be monitored, they will record which website do you visit. It may infringe our freedom.
