- Johannes Fürnkranz
- In this paper, we introduce hyperlink ensembles, a novel type of
ensemble classifier for classifying hypertext documents. Instead of
using the text on a page for deriving features that can be used for
training a classifier, we suggest to use portions of texts from all
pages that point to the target page. A hyperlink ensemble is formed
by obtaining one prediction for each hyperlink that points to a
page. These individual predictions for each hyperlink are
subsequently combined to a final prediction for the class of the
target page. We explore four different ways of combining the
individual predictions and four different techniques for identifying
relevant text portions. The utility of our approach is demonstrated
on a set of Web-pages that relate to Computer Science Departments.
