CSLP@Context07: 4th International Workshop on Constraints and Language Processing

Part of the Sixth International and Interdisciplinary Conference on Modeling and Using Context at Roskilde University, Denmark, 20-24 August 2007

The CSLP@Context07 workshop considers the role of constraints in the representation of language and the implementation of language processing. This theme should be interpreted inclusively: contributions from linguistics, computer science, psycholinguistics and related areas are welcome, and an interdisciplinary perspective is of particular interest.

The collocation with the CONTEXT07 conference underlines the application of constraints for context comprehension and discourse modelling.


Constraints are widely used in linguistics, computer science, and psychology. How they are used, however, varies widely according to the research domain: knowledge representation, cognitive modelling, problem solving mechanisms, etc. These different perspectives are complementary, each one adding a piece to the puzzle. For example, linguistics proposes in-depth descriptions implementing constraints in order to filter out structures by means of description languages, constraint ranking, etc. The constraint programming paradigm, on the other hand, shows that constraints have to be taken as a systematic whole and can thus play a role in building the structures (or can even replace structures). Finally, psycholinguistics investigates the role of constraint systems for cognitive processes in comprehension and production as well as addressing how they can be acquired.


The workshop seeks contributions from different areas working with constraints in relation to language including, but not limited to the topics

Title: Sign Language Processing: Modelling of spatio-temporal constraints


Sign Language (SL) is the deaf community's first language. SL linguistic functioning is completely adapted to the visuo-gestural channel specificity: 1) Several articulators are simultaneously used (hands, arms, gaze, mimic, head, chest), each of them having one or several specific linguistic roles, and possibly interacting with other ones. 2) Iconic features have a key structural role in shaping signed language discourse. 3) SL show a heavy and consistent use of the "signing space", i.e. the portion of space in which the signs are performed. SL Processing systems should be respectful of SL specificities. Therefore, while modelling the signs of the language, i.e. at the lexical level, all the possible context-driven variations must be considered as they are fully part of the language. At the discourse level, sentence construction rules must also account for the extensive use of space of LSF. We will present our current research on SL lexical and discourse modelling based on spatio-temporal constraints, and we will show some examples in the context of SL generation by means of a signing avatar.

Authors are invited to submit either extended abstract or a full paper of up to 12 pages. Each submission will be commented by two or three reviewers. Proceedings are distributed at the workshop, printed in a local series with ISSN no. and made available electronically. A volume at an international publisher will be considered for selected and revised papers, if number and quality of submissions permits. Papers must be prepared in the format for Springer's LNCS/LNAI series which is available at Previously published papers cannot be accepted. Please submit papers as PDF files, using the CSLP 2007 submission page (handled by the EasyChair conference system).
