Elman, when performing an analysis of how the networks he trained were performing the required task, found that the networks had developed "categories" for different groups of words. Even though the network was never presented with the fact that boy, girl, and cat are all nouns, the network reacted to these words in very similar ways. The same was true for different types of verbs. Elman mentions that the networks "could not have performed as they did without developing representations which reflected constituent structure, argument structure, grammatical category, grammatical relations, and number." Gasser and Lee, when presenting their network with inputs that represented verbs to be conjugated into their past tenses, included the semantic properties of each verb as part of the input.
