... generalisations here. The main challenge in this reduction is finding a way of expressing the non-linguistic information as part of the strings that serve as the grammatical in- ference procedure’s input. Here ... nonterminals are indicated via underlining. Here T is the set of all non-None available topics, T  = T ∪ {None}, and W is the set of words ap- pearing in the utterances. The...
