Automatic word alignment is a key step in training statistical machine translation systems. Despite much recent work on word alignment methods, alignment accuracy increases often ...
We have extended the ACL2 theorem prover to automatically prove properties of VHDL circuits with IBM's Internal SixthSense verification system. We have used this extension to...
We investigate the logical issues behind axiomatizing equations that contain both recursive calls and quantifiers in ACL2. We identify a class of such equations, named extended ta...
Abstract. Dominance constraints are widely used in computational linguistics as a language for talking and reasoning about trees. In this paper, we extend dominance constraints by ...
The applications described here follow up the works performed in the recent last years by the Data Structures and Computational Linguistics Group at Las Palmas de Gran Canaria Univ...
Abstract. This paper investigates the learnability of Pregroup Grammars, a context-free grammar formalism recently defined in the field of computational linguistics. In a first ...
One of ACL2’s most interesting features is that it is executable, so users can run the programs that they verify, and debug them during verification. In fact, the ACL2 implemen...
We have developed an extension of ACL2 that includes the implementation of hash-based association lists and function memoization; this makes some algorithms execute more quickly. ...
