Abstract:
1. A system for information searching comprising: a processor; a memory coupled to the processor; computer code loaded into the memory for executing on the processor, for implementing the following functionality: a first layer comprising a first plurality of neurons, each of the first plurality of neurons being associated with a word and with a set of connections to at least some neurons of the first layer; a second layer comprising a second plurality of neurons, each of the second plurality of neurons being associated with an object and with a set of connections to at least some neurons of the second layer, and with a set of connections to at least some neurons of the first layer; a third layer comprising a third plurality of neurons, each of the third plurality of neurons being associated with a sentence and with a set of connections to at least some neurons of the third layer, and with a set of connections to at least some neurons of the first layer and to at least some neurons of the second layer; and a fourth layer comprising a fourth plurality of neurons, each of the fourth plurality of neurons being associated with a document and with a set of connections to at least some neurons of the fourth layer, and with a set of connections to at least some neurons of the first layer, to some neurons of the second layer and to at least some neurons of the third layer; wherein a query to the first layer identifies to a user, through the fourth layer, a set of documents that are contextually relevant to the query, and wherein only some, but not all, connections between each neuron to every other neuron exist.
