The AlvisP2P IR engine
enables efficient retrieval with multi-term queries from a global
document collection distirbuted in a P2P network. In such a network,
each peer publishes its local documents (or local indexes) and
invests a part of its local computing resources (storage, CPU,
bandwidth) to maintain a fraction of a global P2P index. This
investment is rewarded by the network-wide accessibility of the
local documents via the global search facility.
The AlvisP2P engine uses an optimized P2P overlay network and relies on
novel indexing/retrieval mechanisms that ensure low bandwidth
consumption, thus enabling unlimited network growth. An easy-to-install AlvisP2P client can be
used to join an existing P2P network, index local textual or
multimedia documents with collection-specific indexing mechanisms,
and control access rights to them.
