17. The method of claim 12 , further comprising regulating a sum of all activity of all active neurons of the neural network that are excited at any given time.
12. A method comprising: generating a plurality of word neurons; generating a plurality of sentence neurons; generating at least one document neuron, wherein the plurality of word neurons, the plurality of sentence neurons, and the at least one document neuron form at least a portion of a neural network; forming, with a processor of a computing device, a plurality of first connections between at least a portion of the plurality of word neurons and the plurality of sentence neurons; forming, with the processor of the computing device, a plurality of second connections between at least a portion of the plurality of word neurons and the at least one document neuron; exciting a first sentence neuron of the plurality of sentence neurons in response to excitation of the at least one document neuron; and changing a position of the plurality of word neurons on a display based on an input, and wherein the change in the position of one word neuron changes annotation corresponding to at least one of the plurality of sentence neurons.
