thanks to the rise of social networking sites such as Facebook, Twitter, users have the ability to publish and access to relevant information in real time. But a new study suggests that in the information content, web content many links to have take wings to itself.
in the current media age, we will receive a lot of rapidly changing information, whether it is from the blog, news or social networking sites. If you really like to read real-time information, this is certainly a good thing. But it also has a not so subtle defects: a lot of information will be covered by the new content, part also disappeared in silence. Studies have reported that many of the news links that have been shared through Twitter have been invalidated, such as the disappearance of the revolution in the Middle East Arabia spring, which may cause serious problems.
in this research report, the researchers put great news that happened in the past three years as the research object, including the Egyptian revolution, Michael · the death of Jackson, Iran’s election and the outbreak of H1N1. They tracked the corresponding link on Twitter, and finally found an amazing result.
in the link to the page inside, 30% after two and a half years has disappeared
researchers have pointed out that in the past year, 11% of the link content has ceased to exist. If the time is extended to two and a half years, this proportion reached 30%! Speed "decay" based on this information, some experts believe that the news content would disappear within one year accounted for 10% of the total, the rest at a rate of 0.02% per day.
in this report does not explain the reasons for the disappearance of news, it is likely that the site to delete the relevant content or transferred to other places. Science and technology entrepreneurs believe that this information is very valuable, they can be used to track the development of history.
other scientists are also concerned about the disappearance of "digital data". Scotland’s National Library believes that digital life data related to Scotland are disappearing, and they are asking the government to speed up legislation to allow libraries to back up the contents of the major sites. Network pioneer Brewster Kahle is famous in the field of digital archive, because he was involved in the Archive (Internet), so that the early content of the site has been archived. >
