Foundations of Computational Linguistics

???detail.Chair.Picture???

Welcome to the Chair Foundations of Computational Linguistics at IMS Stuttgart. The group has been led by Prof. Jonas Kuhn since January 2010.

Our group works on computational models for processing natural language using both rule-based and statistical techniques. The group members' research interests include the following focus areas:

See also staff list and project list below.


Dependency Parsing
Statistical models for dependency parsing focusing on morphologically rich languages. Our research puts special emphasis on the interaction between morphology and syntax. Our group obtained the best results on the two recent shared tasks on parsing morphologically rich languages (SPMRL 2013 and SPMRL 2014). We are also involved in the adaptation of Universal Dependencies to German.

Selected publications:

Co-reference and Information Structure
Algorithmic and theoretical challenges information structure and coreference. We develop novel algorithms for solving these tasks automatically as well devise annotation schemes and carry out annotation efforts. Of particular interest is the interaction between information structure and prosody, both on the modelling and computational side.

Selected publications:

Natural Language Generation and Semantic Parsing
Algorithmic and architectural aspects of data-driven generation. In particular, the interaction between referring expression generation and surface realization for end-to-end generation systems and morphologically rich languages (e.g. German). More recently, weakly supervised learning of representations for data-to-text generation and semantic parsing.

Selected publications:

Research Infrastructure
Continuing a long tradition of work on corpora and language-technological tools at IMS, our group is involved in projects that focus on infrastructural aspects and the sustainability of language resources. This involves the creation of ready-to-use tool chains and web services, easy access to data by means of visualisations and query tools, the creation of meta data and the documentation of workflows for all kinds of language resources, and the support of collaborative annotation and curation efforts. The group also runs Stuttgart's CLARIN-D center.

Selected publications:

Digital Humanities
We collaborate with various disciplines in the humanities, developing a joint methodological framework for analyzing large text corpora against specific content-analytical questions. One of our goals is to make the aggregated results of such analyses transparent to scholars from the humanities, which requires adaptable models and interactive tools and user interfaces. We have been contributing to several DH-related projects: CLARIN-D, e-Identity, ePoetics, and we are involved in a new Stuttgart center for reflected text analytics (CRETA) in the Digital Humanities.

Theoretical and Computational Semantics
Continuing a long tradition at the IMS, one focus in our group is on Discourse Representation Theory, the syntax-semantics interface, and the role of lexical information in word formation and sentence/discourse semantics.
