In certain embodiments, a computer-implemented method includes accessing first and second data associated with a semantic network, the first data indicating a first plurality of nodes within the semantic network and a first plurality of relationships between the first plurality of nodes at a first time, and the second data indicating a second plurality of nodes within the semantic network and a second plurality of relationships between the second plurality of nodes at a second time. The method further includes generating a first waveform from the first data and a second waveform from the second data. The waveforms indicate an activity level of each of the nodes within the semantic network. The method further includes analyzing the semantic network using the generated first and second waveforms.
