Abstract / Description:We present a new architecture for efficient search and approximate information
filtering in a distributed {P}eer-to-{P}eer ({P2P}) environment of Digital
Libraries. The {M}inerva{L}ight search system uses {P2P} techniques over a
structured overlay network to distribute and maintain a directory of peer
statistics. Based on the same directory, the {MAPS} information filtering
system provides an approximate publish/subscribe functionality by monitoring
the most promising digital libraries for publishing appropriate documents
regarding a continuous query. In this paper, we discuss our system architecture
that combines searching and information filtering abilities. We show the system
components of {M}inerva{L}ight and explain the different facets of an
approximate pub/sub system for subscriptions that is high scalable, efficient,
and notifies the subscribers about the most interesting publications in the
{P2P} network of digital libraries. We also compare both approaches in terms of
common properties and differences to show an overview of search and pub/sub
using the same infrastructure.
