*1 Background
*
Supporting us in many tasks (/thinking, searching/, /memorizing/
and /communicating)/ words are important. Hence, one may wonder
how to build tools supporting their learning and usage
(access/navigation). Alas the answer is not quite as
straightforward as it may seem. It depends on various factors: the
questioner's /background/ (lexicography, psychology, computer
science), the /task /(production/reception), and the /material
support/ (hardware). Words in books, computers and the human brain
are not the same. Obviously, being aware of this, different
communities have focused on different issues —(dictionary
building; creation of navigational tools; representation and
organization of words; time course for accessing a word, etc.)—
yet, their views and respective goals have changed considerably
over time.
Rather than considering the lexicon as a static entity, where
discrete units (words) are organized alphabetically (database
view), dictionaries are now viewed dynamically, i.e., as lexical
graphs, whose entities are linked in various ways (topical
relations; associations) and whose weight links may vary over
time. While lexicographers view words as products (holistic
entities), psychologists and neuroscientists view them as
processes (decomposition), involving various steps or layers
(representations) between an input and an output.
Computational linguists have their own ways to look at words, and
their proposals have also changed quite a bit during the last
decade./Discrete count-based vector representations /have
successively been replaced by /continuous vectors/ (i.e., word
embeddings) and then by /language-model-based contextualized
representations/. These latter are more powerful than any of the
other forms, as they are able to account for context ambiguity,
outperforming the static models (including word-embeddings) in a
broad range of tasks.
As one can see, different communities look at words from different
angles, which can be an asset, as complementary views may help us
to broaden and deepen our understanding of this fundamental
cognitive resource. Yet, this diversity of perspectives can also a
problem, in particular if the field is rapidly moving on, as in
our case. Hence it becomes harder and harder for everyone,
including experts, to remain fully informed about the latest
changes (state of the art). This is one of the reasons why we
organize this workshop. More precisely, our goal is not only to
keep people informed without getting them crushed by the
information glut, but also to help them to perceive clearly what
is new, relevant, hence important. Last, but not least, we would
like to connect people from different communities in the hope that
this may help them to gain new insights or inspirations.
*2 Scope and Topics*
This workshop is about possible /enhancements/ of /lexical
resources/ (representation, organization of the data, etc.). To
allow for this we invite researchers to submit their
contributions. The idea is to discuss the limitations of existing
resources and to explore possible enhancements that take into
account the users’ and the engineers' needs (computational
aspects).
Also, just like in the past we propose again a 'shared task'. This
time the goal is to provide a common benchmark for testing lexical
representations for the automatic identification of lexical
semantic relations (synonymy, antonymy, hypernymy, part-whole
meronymy) in various languages (English, Chinese, and so on).
For this workshop we solicit papers including but not limited to
the following *topics*, each of which can be considered from
various points of view: /linguistics /(lexicography,
computational- or corpus linguistics), /neuro/- or
/psycholinguistics/ (tip-of-the-tongue problem, word
associations), /network/-related sciences (vector-based
approaches, graph theory, small-world problem), and so on.
1 Organization, i.e. structure of the lexicon
* Micro- and macrostructure of the lexicon;
* Indexical categories (taxonomies, thesaurus-like topical
structures,
etc.);
* Map of the lexicon (topology) and relations between words (word
associations).
2 The meaning of words and how to reveal it
* Lexical representation (holistic, decomposed);
* Meaning representation (concept based, primitives);
* Distributional semantics (count models, neural embeddings, etc.
)
3 Analysis of the conceptual input given by a dictionary user
* What information do language producers typically provide when
looking for a word (terms, relations)?
* What kind of relational information do they give: typed or
untyped
relations?
* Which relations are typically used?
4 Methods for crafting dictionaries or indexes
* Manual, automatic or collaborative building of dictionaries and
indexes (crowdsourcing, serious games, etc.);
* Extraction of associations from corpora to build semantic
networks
supporting navigation;
* (Semi-) automatic induction of the link type (e.g., synonym,
hypernym, meronym, ...).
5 Creation of new types of dictionaries
* Concept dictionary;
* Dictionary of larger segments than words (clauses, phrasal
elements);
* Dictionary of patterns or concept-patterns;
* Dictionary of syllables.
6 Dictionary access (navigation and search strategies), interface
issues
* Search based on sound (rhymes), meaning or contextually related
words (associations);
* Determination of appropriate search space based on the user’s
cognitive state (information available at the onset: query) and
meta-knowledge (knowledge concerning the relationship between the
input and the target word), ...
* Identification of typical word access strategies (navigational
patterns) used by people;
* Interface problems, data visualization.
*3 Workshop Submissions*
**
The workshop features two tracks:
* A*regular research track*, where the submissions must be
substantially original.
* A *shared task track*, with submissions consisting of system
description papers.
The regular research track submissions should follow one of the 2
formats:
* *Long papers*(9 content pages + references) should report on
solid
and finished research including new experimental results,
resources
and/or techniques.
* *Short papers*(4 content pages + references) should report on
small
experiments, focused contributions, ongoing research, negative
results and/or philosophical discussion.
Submissions must be anonymized, conform to the style sheet of
COLING (
https://coling2020.org/pages/call_for_papers), and be
submitted via their website
(
https://www.softconf.com/coling2020/CogALex/
<https://www.google.com/url?q=https%3A%2F%2Fwww.softconf.com%2Fcoling2020%2FCogALex%2F&sa=D&sntz=1&usg=AFQjCNEAUzHo0vS4_MVdi-nlx1qIxrCpUA>).
While some papers may be accepted only as posters, in the
proceedings no distinction will be made between them and full
papers.
