Meeting Description:

Following the success of the first  CWI shared task at SemEval 2016, we are
organizing the Second CWI Shared Task co-located with the BEA Workshop 2018 at
NAACL-HLT in New Orleans, USA.

The Second CWI Shared Task features a multilingual dataset and participants
can choose to participate in one or more of the following tracks:

English monolingual CWI
German monolingual CWI
Spanish monolingual CWI
Multilingual CWI shared task with French test set (English, Spanish, and
German datasets can be used for training)

For more information please check the Call for Participation.


Call for Participation:

Motivation

Many lexical simplification systems have been proposed up to this date (Glavaš
and Štajner, 2015; Paetzold and Specia, 2016a). As it has been shown by
Paetzold and Specia, 2016b, systems that discern between complex and simple
words before simplification tend to be more reliable in practice. Therefore,
the automatic identification of words that are difficult for a given target
population is an important step for building better performing lexical
simplification systems. This process is known as complex word identification
(CWI) (Shardlow, 2013).

The first shared task on CWI was organized at the SemEval 2016 (Paetzold and
Specia, 2016c). It featured 21 teams that competed submitting 42 systems
trained to predict whether words in a given context were complex or
non-complex for a non-native English speaker. Following the success of the
first CWI shared task at SemEval 2016 we organize a second edition of the
challenge at the BEA workshop 2018.

The goal of this year's CWI shared task is to predict which words can be
difficult for a non-native speaker, based on annotations collected from a
mixture of native and non-native speakers.

Tracks

Monolingual English CWI shared task
Monolingual Spanish CWI shared task
Monolingual German CWI shared task
Multilingual CWI shared task with French test set (English, Spanish, and
German datasets can be used for training)

Tasks

Binary classification task
Probabilistic classification task

In the binary classification task, the participants are asked to label the
given target word in particular context as complex or simple.

In the probabilistic classification task, the participants are asked to give a
probability of the given target word in particular context being complex.

Participants can submit up to two systems for each track and for each task.
