A Learning Model of Lexicon
In Gold's (1967) model, a learner is a function from information to guesses on grammar at each time. This paper models a learning process of lexical knowledge and considers a learner to be a function from a set of lexicon to a poset of lexical entries. A polysemous word may be assigned a set of entries while uncertainty maps a word to multiple candicates. The lattice of lexical entries has a null element in case no meaning is assigned.
