Information storage and retrieval
First Claim
1. An information retrieval system in which a set of distinct information items map to respective nodes in an array of nodes by mutual similarity of said information items, so that similar information items map to nodes at similar positions in the array of nodes;
- said system comprising;
(i) a data network;
(ii) an information retrieval client system connected to said data network; and
one or more information item storage nodes connected to the data network;
in which;
(i) each storage node comprises a store for storing a plurality of information items and an indexer for transmitting data derived from information items stored at that storage node to said client system via said data network; and
(ii) said client system comprises logic, responsive to data received from said indexer of a storage node, for generating a node position in respect of each information item represented by said received data.

Abstract
An information retrieval system in which a set of distinct information items map to respective nodes in an array of nodes by mutual similarity of the information items, so that similar information items map to nodes at similar positions in the array of nodes; comprises a data network; an information retrieval client system connected to the data network; and one or more information item storage nodes connected to the data network; in which: each storage node comprises a store for storing a plurality of information items and indexing logic for transmitting data derived from information items stored at that storage node to the client system via the data network; and the client system comprises logic, responsive to data received from the indexing logic of a storage node, for generating a node position in respect of each information item represented by the received data.
