Trackback Spam Distinction Using Similarity of Contents

[Abstract]
An increase of trackback spam becomes a problem as blog spreads, and it is necessary to be excluded. Distinction without people is necessary because many of trackback spams are mechanically done. Then, we experimented on the trackback spam distinction technique using the similarity of the article. However, it is difficult to compare content of the article by the meaning. Then, it was considered that outline of the article was the same that the same noun as two articles was included. As a result, rate of the track back spam rises when the similarity of the article is low.
