Evaluating Unsupervised Part-of-Speech Tagging for Grammar Induction
This paper explores the relationship between various measures of unsupervised part-of-speech tag induction and the performance of both supervised and unsupervised parsing models t...

Mechanisation of PDA and Grammar Equivalence for Context-Free Languages
We provide a formalisation of the theory of pushdown automata (PDAs) using the HOL4 theorem prover. It illustrates how provers such as HOL can be used for mechanising complicated p...

Approximation and Exactness in Finite State Optimality Theory
Previous work (Frank and Satta, 1998; Karttunen, 1998) has shown that Optimality Theory with gradient constraints generally is not finite state. A new finite-state treatment of gr...

A Formal Scheme for Multimodal Grammars
We present in this paper a formal approach for the representation of multimodal information. This approach, thanks to the to use of typed feature structures and hypergraphs, gener...
