This work addresses the problem of bootstrapping of lexical categories, i.e. how children learn that words can be clustered according to categorical restrictions which define their use in language, separating, for example, nouns from verbs.

The experiments which are going to be described tackle the issue of which properties in the input children receive determine the usefulness of linguistic items in supporting the learning of lexical categories, with a focus on how frequent a cue is, on how many other linguistic units it co-occurs with (i.e. how diverse it is), and on how predictable it is given co-occurring linguistic items. A number of computational simulations are carried out using corpora of transcribed child-directed speech.
