Kurzfassung
We address the problem of efficiently ranking the best peers w.r.t.
a query with multiple, equally weighted predicates -- conjunctive
queries -- in shortcut overlay networks. This problem occurs when
routing queries in unstructured peer-to-peer networks, such as in
peer-to-peer information retrieval applications. Requirements for
this task include, e.g., full autonomy of peers as well as full
control over own resources. Therefore prominent resource location
and query routing schemes such as distributed hash tables can not be
applied in this setting. In order to tackle these requirements we
combine a new resource location and query routing approach that
exploits social metaphors of topical experts and experts' experts
with standard IR measures for ranking peers based on collection-wide
information. The approach has been fully tested in simulation runs
for skewed data distributions and network churn and has been
partially implemented in the
Bibster system.
