It is known that context words tend to be selftriggers, that is, the probability of a content word to appear more than once in a document, given that it already appears once, is significantly higher than the probability of the first occurrence.We look at self-triggerability across hyperlinks on the Web.We show that the probability of a word to appear in a Web document depends on the presence of in documents pointing to .In Document Modeling, we will propose the use of a correction factor, , which indicates how much more likely a word is to appear in a document given that another document containing the same word is linked to it.
