Infer the relationship of reintroduce in microblogs

In microblogs contexts like Twitter, a large number of users retweet messages by making use of an informal convention such as "RT @user" or "via ©user". However, there are lots of users reintroducing tweets which are similar with the tweets previously posted by other users, but without acknowledgement of a source with an informal convention such as "RT @user" or "via ©user". In this paper, we will infer the relationship of reintroduce in microblogs by the distribution of the time interval and the similarity of two tweets and find the acknowledgement of a source. Experiments were conducted on a real dataset from Twitter containing about 0.26 million users and 2.7 million tweets. Experimental results indicate that out method is effective to infer the relationship of reintroduce.
