2nd and Final Call for CogALex
Cognitive Aspects of the Lexicon (CogALex-V)
https://sites.google.com/site/cogalex2016/home
Workshop co-lated with COLING (the 26th International Conference on
Computational Linguistics, Osaka, Japan), December 12, 2016
Invited speaker: Chris Biemann (LT + HCC, Universität Hamburg , Germany)
We are pleased to announce the 5th Workshop on 'Cognitive Aspects of the
Lexicon' (Cogalex-V), taking place just before COLING (Osaka, Japan),
December 12, 2016.
1 Context and background
The way we look at the lexicon (creation and use) has changed
dramatically over the past 30 years. While in the past being considered
as an appendix to grammar, the lexicon has now moved to centre stage.
Indeed, there is hardly any task in NLP which can be conducted without
it. Also, rather than considering it as a static entity (database view),
dictionaries are now viewed as dynamic networks, akin to the human
brain, whose nodes and links (connection strengths) may change over time.
Linguists work on products, while psychologists and computer
scientists deal with processes. They decompose the task into a set of
subtasks, i.e. modules between which information flows. There are
inputs, outputs and processes in between. A typical task in language
processing is to go from meanings to sound or vice versa, the two
extremes of language production and language understanding. Since this
mapping is hardly ever direct, various intermediate steps or layers
(syntax, morphology) are necessary.
Most of the work done by psycholinguists has dealt with the
information flow from meaning (or concepts) to sound or the other way
around. What has not been addressed though is the creation of a map of
the mental lexicon, that is a represention of the way how words are
organized or connected.
In this respect WordNet and Roget's Thesaurus are probably closest to
what one can expect these days. This being said, to find a word in a
resource one has to reduce the search space (entire lexicon) and this is
done via the knowledge one has at the onset of search. While the
information stored in the lexicon is a product, its access is clearly a
(cognitive, i.e. knowledge-based) process.
1.1 Goal
The goal of COGALEX is to provide a forum for researchers in NLP,
psychologists, computational lexicographers and users of lexical
resources to share their knowledge and needs concerning the
construction, organization and use of a lexicon by people (lexical
access) and machines (NLP, IR, data-mining).
Like in the past (2004, 2008, 2010, 2012 and 2014), we will invite
researchers to address various unsolved problems, by putting this time
stronger emphasis though on distributional semantics (DS). Indeed, we
would like to see work showing the relevance of DS as a cognitive model
of the lexicon. The interest in distributional approaches has grown
considerably over the last few year, both in computational linguistics
and cognitive sciences. A further boost has been provided by the recent
hype around deep learning and neural embeddings. While all these
approaches seem to have great potential, their added value to address
cognitive and semantic aspects of the lexicon still needs to be shown.
This workshop is about possible enhancements of lexical resources and
electronic dictionaries, as well as on any aspect relevant to the
achieve a better understanding of the mental lexicon and semantic
memory.We solicit contributions including but not limited to the topics
listed here below, topics, which can be considered from any of the
following points of view:
* (computational, corpus) linguistics,
* neuro- or psycholinguistics (tip of the tongue problem, associations),
* network related sciences (sociology, economy, biology),
* mathematics (vector-based approaches, graph theory, small-world
problem), etc.
We also plan to organize a “friendly competition” for corpus-based
models of lexical networks and navigation, i.e. lexical access (see below).
1.2 Possible Topics
1.2.1 Analysis of the conceptual input of a dictionary user
* What does a language producer start out with and how does this input
relate to the target form? (meaning, collocation, topically related,
etc.)
* What is in the authors' minds when they are generating a message and
looking for a word?
* What does it take to bridge the gap between this input and the
desired output (target word)?
1.2.2 The meaning of words
* Lexical representation (holistic, decomposed)
* Meaning representation (concept based, primitives)
* Distributional semantics (count models, neural embeddings, etc. )
* Neurocomputational theories of content representation.
1.2.3 Structure of the lexicon
* Discovering structures in the lexicon: formal and semantic point of
view (clustering, topical structure)
* Evolution, i.e. dynamic aspects of the lexicon (changes of weights)
* Neural models of the mental lexicon (distribution of information
concerning words, organization of words)
1.2.4 Methods for crafting dictionaries or indexes
* Manual, automatic or collaborative building of dictionaries and
indexes (crowd-sourcing, serious games, etc.)
* Impact and use of social networks (Facebook, Twitter) for building
dictionaries, for organizing and indexing the data (clustering of
words), and for allowing to track navigational strategies, etc.
* (Semi-) automatic induction of the link type (e.g. synonym,
hypernym, meronym, association, collocation, ...)
* Use of corpora and patterns (data-mining) for getting access to
words, their uses, combinations and associations
1.2.5 Dictionary access (navigation and search strategies), interface
issues,
* Search based on sound, meaning or associations
* Search (simple query vs. multiple words)
* Search-space determination based on user's knowledge, meta-knowledge
and cognitive state (information available at the onset, knowledge
concerning the relationship between the input and the target word, ...)
* Context-dependent search (modification of users’ goals during search)
* Navigation (frequent navigational patterns or search strategies used
by people)
* Interface problems, data-visualization
* Creative ways of getting access to and using word associations
(reading between the lines, subliminal communication).
2 Description of the shared tasks associated with the workshop.
As part of the workshop, we propose a shared task concerning the
corpus-based identification of semantic relations. The goal of this
“competition between gentlemen" is less the discovery of the best
system, as the testing of the relative efficiency of different
distributional models and other corpus-based approaches on a
challenging semantic task. We will provide the training and test data,
and the participants are expected to submit a short paper (4 pages)
describing their approach and evaluation results (using the official
scoring scripts), together with the output produced by their system on
the test data.
