Abstract:
In this paper, we study the distribution of relevant documents in
aggregates, formed by grouping the retrieved documents according
to their domain. For each aggregate, we take into account its size,
and a measure of the correlation between its incoming and outgoing
hyperlinks. We report on a preliminary experiment with two
TREC topic distillation tasks, where we find that larger aggregates,
or those aggregates with correlated hyperlinks, are more likely to
contain relevant documents. This result shows that the distribution
of domain-level aggregates is potentially useful for finding relevant
documents.
