Paper Abstract:
|
In this paper, we propose a document vector space model where weights of noun terms vary depending on positions
within the texts. We extend extended anchor texts (i.e., extra texts surrounding anchor texts) with the exponential
potential. That is, the weight of a noun term decreases exponentially as the distance between the term and hyperlink
increases. In order to cluster blogspace, we use the hybrid vector space model which takes both texts and hyperlinks into
account. We evaluate the effectiveness of our extended anchor text model and hyperlinks on clustering blog search
results. We also discuss recommendation based on clustering. |
