1. An apparatus comprising: a memory; a processor operatively coupled to the memory; and a neural network comprising: a plurality of word neurons; a plurality of sentence neurons; at least one document neuron; a plurality of first connections between at least a portion of the plurality of word neurons and the plurality of sentence neurons; and a plurality of second connections between at least a portion of the word neurons and the at least one document neuron, wherein the neural network is configured to excite a first sentence neuron of the plurality of sentence neurons in response to excitation of the at least one document neuron; wherein the processor is configured to change 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.
