29. An associative memory method according to claim 27 : wherein observing comprises: observing into the network of entity associative memory networks, the associations among a respective observer entity and a plurality of observed entities that are observed by the respective observer entity, based on the plurality of input documents; observing into the network of document associative memory networks, the associations among observed entities in a respective observer input document; observing into the network of feedback associative memory networks, the associations among a plurality of observed entities for a respective observer positive and/or negative evaluation for a respective task of a respective user; and observing into the network of community associative memory networks, the associations among a respective observer entity, a plurality of observed entities that are observed by the respective observer entity and a plurality of observed tasks of a plurality of users in which the observer entity was queried; and wherein imagining comprises imagining associations of entities, documents, users and/or tasks from the network of entity associative memory networks, the network of document associative memory networks, the network of feedback associative memory networks and the network of community associative memory networks, in response to user queries.

An associative memory method according to claim 29 wherein imagining associations of entities, documents, users and/or tasks comprises: querying the network of entity associative memory networks and the network of feedback associative memory networks to imagine associations of entities and user-task positive and/or negative evaluations in response to user queries; querying the network of document associative memory networks and the network of feedback associative memory networks to imagine associations of documents and user-task positive and/or negative evaluations in response to user queries; and querying the network of community associative memory networks to imagine associations of other user-tasks in response to user queries.
