THEMES

Research in NLP increasingly requires sophisticated software architectures. Because there is no agreed "integrated" model of language processing, researchers often produce ad hoc and application-specific solutions, while NLP platforms help by bringing components together and making them interoperable. Due to the complex nature of NLP applications — and language itself — one needs to mix in the same process different models, resources and algorithms, leading to important problems of interoperability and data exchange. Moreover, the increasing complexity of linguistic models implies sophisticated formalisation tools, and the development of experimental studies on large corpora also brings strong constraints on the software environments.

These various characteristics and requirements raise many questions which will be the focus of the present special issue on platforms for language processing.

Two interrelated and complementary aspects are relevant: an architectural and a methodological one.

1) Architectural issues

Bringing together different modules raises many architectural and technical questions, centered around interoperability and data exchange, such as:
-  interoperability between representation formats of corpora, linguistic resources, documents and annotations; possible standardisation;
-  technical compatibility of heterogeneous algorithms and data: portability, availability, maintainability, etc;
-  graphical user interfaces supporting computer scientists and/or linguists to assemble sets of "components" and to visualise and debug the results of their application to corpora;
-  multimodality and multilinguism;
-  software execution models: pipeline, agent-based architectures, distributed web services, etc; techniques for limiting errors from propagating into subsequent modules; efficiency comparisons of the various kinds of architectures; scalability (massive data, simultaneous on-line users...).

2) Methodological issues

The scientific approach which consists in projecting a certain linguistic model ­ or a set of models — on the same data or corpora also raises interesting questions:
-  formalisation: which formalisms are appropriate for the various levels of linguistic analysis? How can they be made interoperable? What should be considered first: the expressivity of a formalism or the complexity of the associated algorithms?
-  descriptive power: how can we ensure the declarative nature of NLP processes, from linguistic rules to the specification of process chaining ? Is it possible to have a convergence of descriptive and prescriptive models?
-  repeatability: how to ensure that an experiment, based on complex algorithms, can be reproduced? How to share and capitalize on operational models and resources?
-  modularity: how to make a complex process independent of the choice of a particular component for a particular task? Reuse and adaptation of resources and components; support for multiple annotations;
-  evaluation of composite processes;
-  theoretical productivity: by bringing together different "local" models can we study new linguistic phenomena, at a higher complexity level?

Presentation of concrete experiments embedding NLP platforms into application-oriented software systems (human-machine interfaces, information retrieval and extraction, terminology/ontology constitution, automated translation...) is warmly encouraged. Description of specific NLP platforms is also welcome, and authors should then clearly explain the underlying principles and hypotheses, in order to contribute to the general discussion.

THE JOURNAL

TAL (Traitement Automatique des Langues / Natural Language Processing) is a forty year old international journal published by ATALA (French Association for Natural Language Processing) with the support of CNRS (National Centre for Scientific Research). It has moved to an electronic mode of publication, with printing on demand. This affects in no way its reviewing and selection process.

The first electronic issues are online on the journal Web site:

-  Regular issue 2006 47-1.
-  Special issue 2006 47-2 "Computational Approaches to Discourse and Document Processing" ("Discours et document : traitements automatiques").
-  Regular issue 2006 47-3.

The tables of contents for the 2004-2006 issues can be consulted on this Web site.

The tables of contents for the 1991-2004 issues can be found on the former Web site of the journal.
