As a result contents of documents can be 'propagated' along the hyperlinks.
for example, suppose web page A cites page B and page B cites page C, then the content of page A is influenced by that of page B, and the content of page B is further influenced by the content of page C. HTM is able to more accurately represent the contents of hypertexts, and thus is more useful for text processing such as topic discovery and document classification.
