Apologies for multiple postings

Final Call for Paper Submissions to Cogalex-II

2nd Workshop on Cognitive Aspects of the Lexicon
pre-conference workshop of COLING 2010 (Beijing, China)

endorsed by the Special Interest Group on the Lexicon of the
Association for Computational Linguistics (SIGLEX)

Submission deadline: May 30, 2010
Cogalex workshop (August 22, 2010)




The aim of this workshop is to bring together researchers involved in the construction and application of electronic dictionaries to discuss modifications of existing resources in line with the users' needs, thereby fully exploiting the advantages of the digital form. Given the breadth of the questions, we welcome reports on work from many perspectives, including but not limited to: computational lexicography, psycholinguistics, cognitive psychology, language learning and ergonomics.


Whenever we read a book, write a letter or launch a query on a search engine, we always use words, the shorthand labels and concrete forms of abstract notions (concepts, ideas and more or less well specified thoughts). Yet, words are not only vehicles to express thoughts, they are also means to conceive them. They are mediators between language and thought, allowing us to move quickly from one idea to another, refining, expanding or illustrating our possibly underspecified thoughts. Only words have these unique capabilities, which is why they are so important.

Obviously, a good dictionary should contain many entries and a lot of information associated with each one of them. Yet, the quality of a dictionary depends not only on coverage, but also on accessibility of information. Access strategies vary with the task (text understanding vs. text production) and the knowledge available at the moment of consultation (word, concept, speech sounds). Unlike readers who look for meanings, writers start from them, searching for the corresponding words. While paper dictionaries are static, permitting only limited strategies for accessing information, their electronic counterparts promise dynamic, proactive search via multiple criteria (meaning, sound, related words) and via diverse access routes. Navigation takes place in a huge conceptual lexical space, and the results are displayable in a multitude of forms (e.g. as trees, as lists, as graphs, or sorted alphabetically, by topic, by frequency).

Many lexicographers work nowadays with huge digital corpora, using language technology to build and to maintain the lexicon. But access to the potential wealth of information in dictionaries remains limited for the common user. Yet, the new possibilities of electronic media in terms of comfort, speed and flexibility (multiple inputs, polyform outputs) are enormous. Computational resources are not prone to the same limitations as paperbound dictionaries. The latter were limited in scope, being confined to a specific task (translation, synonyms, ...) due to economical reasons, but this limitation is not justified anymore.

Today we can perform all tasks via one single resource, which may comprise a dictionary, a thesaurus and even more. The goal of this workshop is to perform the groundwork for the next generation of electronic dictionaries, that is, to study the possibility of integrating the different resources, as well as to explore the feasibility of taking the user's needs, knowledge and access strategies into account.


For this workshop we invite papers including but not limited to the following topics:
  1. Conceptual input of a dictionary user. What is in the authors' minds when they are generating a message and looking for a word? Do they start from partial definitions, i.e. underspecified input (bag of words), conceptual primitives, semantically related words, something akin to synsets, or something completely different? What does it take to bridge the gap between this input, incomplete as it may be, and the desired output (target word)?
  2. Organizing the lexicon and indexing words. Concepts, words and multi-word expressions can be organized and indexed in many ways, depending on the task and language type. For example, in Indo-European languages words are traditionally organized in alphabetical order, whereas in Chinese they are organized by semantic radicals and stroke counts. The way words and multi-word expressions are stored and organized affects indexing and access. Since knowledge states (i.e. knowledge available when initiating search) vary greatly and in unpredictable ways, indexing must allow for multiple ways of navigation and access. Hence the question: what organizational principles allow the greatest flexibility for access?
  3. Access, navigation and search strategies based on various entry types (modalities) and knowledge states. Words are composed of meanings, forms and sounds. Hence, access should be possible via any of these components: via meanings (bag of words), via forms, simple or compound ('hot, dog' vs. 'hot-dog'), and via sounds (syllables). Access should even be possible if input is given in an incomplete, imprecise or degraded form. Furthermore, to allow for natural and efficient access, we need to take the users' knowledge into account (search space reduction) and provide adequate navigational tools, metaphorically speaking, a map and a compass. How do existing tools address these needs, and what could be done to go further?
  4. NLP applications: Contributors can also demonstrate how such enhanced dictionaries, once embedded in existing NLP applications, can boost performance and help solve lexical and textual-entailment problems, such as those evaluated in SEMEVAL 2007, or, more generally, generation problems encountered in the context of summarization, question-answering, interactive paraphrasing or translation.

Authors are invited to submit original, unpublished work on any of the topic areas of the workshop. As reviewing will be blind the paper should not include the authors' names and affiliations. Furthermore self-references revealing the authors' identity should be avoided.
The submitted papers can be of any of the following two types:
  1.     Long papers should present completed work and should not exceed 10 pages (including data, tables, figures, and references).
  2.     Short papers can present work in progress (up to 6 pages)
Please include a one-paragraph abstract of the work (about 200 words). While the paper length may differ, the format will be the same as the one of the main conference. Hence we suggest that you get hold of the adequate style sheets (LATEX or MS Word) which can be found here: http://www.coling-2010.org/SubmissionGuideline.htm.

Submission will be electronic (PDF format only) via the START conference management software (https://www.softconf.com/coling2010/COGALEX2010/).

Double submission policy: Authors may submit the same paper at several meetings, but a paper published at this workshop cannot be published elsewhere. In case of double submission, you must notify the workshop organizers in a separate e-mail, so we know that the paper might be withdrawn depending on the results elsewhere.
