 Frieder Stolzenburg, Stephan Höhne, Ulrich Koch, Martin Volk, Constraint Logic Programming for Computational Linguistics, In: Selected Papers of the 1st International Conference on Logical Aspects of Computational Linguistics, SpringerLink, . (Conference or Workshop Paper)
In computational linguistics, we are often interested in developing grammar
formalisms declaratively. However, tractability often becomes a problem then. Therefore,
we want to argue for the use of constraint logic programming (CLP), and it is yet
interesting to note that most logic based natural language systems have not attempted to
employ CLP. Our framework and the prototype system UBS combines logic programming
with constraint domains (e.g. typed feature structures and nite sets) and constraint
techniques (e.g. coroutining). |

Martin Volk, Probing the lexicon in evaluating commercial MT systems, In: Proceedings of ACL/EACL Joint Conference, Madrid, Spain, . (Conference or Workshop Paper)
In the past the evaluation of machine translation systems has focused on single system evaluations because there were only few systems available. But now there are several commercial systems for the same language pair. This requires new methods of comparative evaluation. In the paper we propose a black-box method for comparing the lexical coverage of MT systems. The method is based on lists of words from different frequency classes. It is shown how these word lists can be compiled and used for testing. We also present the results of using our method on 6 MT systems that translate between English and German.

Martin Volk, Dirk Richarz, Experiences with the GTU grammar development environment, In: Workshop on Computational Environments For Grammar Development And Linguistic Engineering at the ACL/EACL Joint Conference, Madrid, Spain, . (Conference or Workshop Paper)
In this paper we describe our experiences with a tool for the development and testing of natural language grammars called GTU (German: Grammatik-Testumgebumg; grammar test environment). GTU supports four grammar formalisms under a window-oriented user interface. Additionally, it contains a set of German test sentences covering various syntactic phenomena as well as three types of German lexicons that can be attached to a grammar via an integrated lexicon interface. What follows is a description of the experiences we gained when we used GTU as a tutoring tool for students and as an experimental tool for CL researchers. From these we will derive the features necessary for a future grammar workbench. |

Martin Volk, Michael Jung, Dirk Richarz, GTU - A workbench for the development of natural language grammars, In: Proceedings of the Conference on Practical Applications of Prolog, Paris, France, . (Conference or Workshop Paper)
In this report we present a Prolog tool for the development and testing of natural language grammars called GTU (German: Grammatik-Testumgebung; grammar test environment). GTU offers a window-oriented user interface that allows the development and testing of natural language grammars under three formalisms. In particular it contains a collection of German test sentences and two types of German lexicons. Both of the lexicons can be adapted to a given grammar via an integrated lexicon interface. GTU has been implemented in Prolog both under DOS and UNIX. It was originally developed as a tutoring tool to support university courses on syntax analysis but in its UNIX-version it allows for the development of large grammars. |
