18. The one or more computer-readable storage media according to claim 15 , wherein the path is identified using a graphing algorithm or a nearest neighbor technique for the outputs of the individual submodels.
15. One or more computer-readable storage media comprising instructions which, when executed by one or more processing devices, cause the one or more processing devices to perform acts comprising: accessing a parameterized representation of a first lexical structure; computing outputs for individual submodels of a model structure using the parameterized representation of the first lexical structure; identifying lexical units based on the outputs of the individual submodels; selecting a path through the model structure based on distances between the outputs and the identified lexical units; and outputting a second lexical structure comprising the identified lexical units along the path.
