I've been involved in a number of research projects.
This page is intended as a pointer to those projects.
To make access to them as simple as possible, I put the projects into the categories past
first the ongoing projects, and then projects that I was involved in
in the past, in alphabetical order.
With substantial software contributions by Martin Lazarov, Johannes Dellert, Kilian Evang and I
have been working on a comprehensive graphical grammar development environment called
Kahina for logic programming
and grammar development in the TRALE system. The project was initially funded by a
for Johannes and Kilian. Important Kahina modules that were not covered by this stipend
were supported by very substantial software development money provided by Stefan Müller,
Gert Webelhuth, and Detmar Meurers.
(an effort is made to present them in an intuitive alphabetical order)
A1 of the
SFB 441 (1999-2001)
The topic of this project was Repräsentation und
Erschließung linguistischer Daten, and I was working with
Manfred Sailer on questions of how to represent linguistic data.
A5 of the
SFB 441 (2002-2008)
This is a project which started in the second phase of the
SFB 441. We investigated irregularities
and idiosyncracies in natural languages which have traditionally
caused many analytical problems for formal theories of grammar.
Laura Kallmeyer's Emmy Noether Nachwuchsgruppe, we hosted the semantics
workshop Tübinger Welten, Ereignisse, Situationen und Zeiten on
June 23rd, 2006.
B8 of the SFB
B8 was concerned with the implementation of a fragment of German in
HPSG. In B8 we did research on building implementation platforms
for HPSG grammars, the logical foundations of HPSG, and various
empirical linguistic phenomena in German. The people in the HPSG group
of the SFB 340 included Mike Calcagno, Kordula De Kuthy, Frederik Fouvry, Thilo
Götz, John Griffith, Paul John King, Detmar Meurers, Guido
Minnen, Gerald Penn, Manfred Sailer, Markus Steinbach, Beata
Trawinski, Jesse Tseng, and Heike Winhart.
In the BulTreeBank project Kiril Simov and his colleagues in Sofia
developed an HPSG-based syntactic treebank of Bulgarian. The SfS in
Tübingen collaborated with the research group in Sofia on various
issues concerning the development of the Bulgarian treebank. I spent some
time at the Bulgarian Academy of Science
as a visitor in spring 2001.
CLAIRE (Constraint Linguistics: An Interdisciplinary Review and Evaluation)
was a collaborative research project between the SfS and the
Computational Linguistics/Machine Translation Group (CL/MT Group)
University of Essex in England. CLAIRE was conducting a comparative study of
Lexical Functional Grammar (LFG) and Head-Driven Phrase Structure
The CLaRK programme was a graduate programme for students from
central and eastern Europe, which we conducted with colleagues in
Bulgaria. Please visit the
CLaRK pages to find out more about what this
was all about. There even were two Summer Schools!
CoGETI: Forschungsnetzwerk Constraintbasierte Grammatik (2005-2010)
The CoGETI network consisted of a group of researchers from five German
universities who share interests in the development of constraint-based
grammars. Details about the goals of the network and its structure can
be found on the CoGETI web pages.
at the SFB 441 hosted the
CoGETI Workshop on Negative Polarity Items
in early February 2006.
Deep semantic constraint-based processing of Polish (2004-2005)
The research in our project on Polish was conducted by
Adam Przepiórkowski at the
Linguistic Engineering Group at the Institute of Computer Science,
Polish Academy of Sciences, in Warsaw, and myself. The purpose of this
project was to investigate certain phenomena of Polish which are
particularly challenging for linguistic analysis and processing, and
to implement a fragment of Polish.
Medienintensive Lehrmodule in der Computerlinguistik-Ausbildung
(MiLCA) started in summer 2001 and ran through 2003. I directed a
project in the MiLCA consortium (Modul
A4, Grammatikformalismen und Parsing - Grammar Formalisms and
Parsing) that designed a course in HPSG covering the mathematical
foundations, linguistic theorizing, and the implementation of HPSG
grammars in the TRALE system.
From July 2002 through July 2003 the Strukturfonds of the University
of Tübingen funded a project in which we were creating on-line resources on
HPSG and started a co-operation with Gerald Penn of the
Computer Science Department of the University of Toronto on the
efficient implementation of a new combinatorial system for
model-theoretic semantics in TRALE. The result of the project
(besides publications) was the first prototype of an implementation of
Lexical Resource Semantics. The research in this project was
conducted by Manfred Sailer, Gerald Penn and myself.
This was a project about machine translation of spoken dialogues from
German to Japanese and vice versa. I was involved in designing a
Baumbank (tree bank) for German.
