Dear colleagues

Please distribute the following Call for Papers among colleagues, and
accept our apologies for multiple postings.


First Call for Papers

Cognitive Aspects of the Lexicon (Cogalex-2)
2nd SIGLEX endorsed COLING Workshop (August 22, 2010, Beijing)

Submission deadline: May 30, 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

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:

    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)?

    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?

    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?

    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.


      + Deadline for paper submissions: May 30, 2010
      + Notification of acceptance:  June 30, 2010
      + Camera-ready papers due: July 10, 2010
      + Cogalex workshop:  August 22, 2010


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. Further details concerning the paper submission will be
announced closer to the May 30 submission deadline.


Next to COLING 2010 there are two conferences workshop participants
may be interested in:

    The 7th International Conference on Cognitive Science (ICCS) which
    takes place August 17 to 20, 2010, just before COLING. It is our
    hope that this unique opportunity will foster scientific exchange
    between the scientific communities of Computational Linguistics
    and Cognitive Science. The ICCS' venue is the China National
    Convention Center (CNCC) which is close to COLING's site, the
    Beijing International Convention Center (BICC), located on the
    other side of the China National Stadium ('Bird Nest').

    Also somewhat related is the 6th IEEE International Conference on
    Natural Language Processing and Knowledge Engineering (IEEE
    NLP-KE'10). Yet, as it is scheduled for August 21 to 23, 2010, it
    overlaps with our workshop.
