===========================================

Short papers are invited for the one-day workshop to be held in Jeju Island, 
Korea, on 13 July 2012.

Until recently, research in Natural Language Processing (NLP) has focused 
predominantly on propositional aspects of meaning. For example, semantic role 
labeling, question answering or text mining tasks aim at extracting information 
of the type "who does what, when and where". However, understanding language 
involves also processing Extra-Propositional Aspects of Meaning (EPAM), such as 
factuality, uncertainty, or subjectivity, since the same propositional meaning 
can be presented in a diversity of statements. While some work on phenomena 
like subjectivity has been carried out in the context of sentiment processing, 
other phenomena like the detection of sarcasm have received less attention.

By proposing this workshop we aim at bringing together scientists working on 
EPAM from any area related to computational language learning and processing. 
By EPAM we understand aspects of meaning that cannot be captured with a 
propositional representation such as the output of semantic role labelers.

For instance, the meaning of the sentence in Example (1) can be represented 
with the proposition ADD(earthquake,further threats to the global economy), 
whereas representing the meaning of the sentences in Example (2) requires 
additional mechanisms, despite the fact that all sentences share a 
propositional meaning.

(1)    The earthquake adds further threats to the global economy.

(2)    Does the earthquake add further threats to the global economy?
         The earthquake adds further threats to the global economy, doesn't it?
         The earthquake does not add further threats to the global economy.
         The earthquake will never add further threats to the global economy.
         The earthquake will probably add further threats to the global economy.
         Who could (possibly) think the earthquake adds further threats to the 
global economy?
         The earthquake might have added further threats to the global economy.
         The last analysis shows that the earthquake will add further threats to 
the global economy.
         It is expected that the earthquake will add further threats to the 
global economy.
         It has been denied that the earthquake adds further threats to the 
global economy.

Some of the sentences above could also be combined in a paragraph such as (3), 
which shows that the same event can be presented from different perspectives, 
at different points in time and with different extra-propositional meanings.

(3) The main question 6 months ago was whether the earthquake would add further 
threats to the global economy. Some days after the earthquake the authorities 
were convinced that it would be possible to minimize the impact of the 
earthquake. Most economists didn't share this view and predicted a high 
economic impact of the earthquake. However, a recent study about the 
earthquake's effect has shown that, although the earthquake might have added 
further threats to the global economy, its negative impact can be controlled by 
applying the right measures.

While the area of EPAM comprises a broad range of phenomena, this workshop will 
focus mainly on the aspects related to modality understood in a general sense 
(modalities, hedging, certainty, factuality), negation, attitude, and 
irony/sarcasm. Since many of these phenomena cannot be adequately modeled 
without taking (discourse) context into account, the workshop also touches on 
discourse phenomena in so far as they relate to extra-propositional aspects of 
meaning.

The workshop is a follow-up to Negation and Speculation in Natural Language 
Processing (NeSp-NLP 2010) held in Uppsala, Sweden, in July 2010.

SCOPE AND TOPICS

In particular, the workshop will address the following topics, although it will 
be open to other related topics:

- Negation
- Modality
- Hedging
- Factuality
- Certainty
- Subjectivity, attitude
- Evidentiality
- Irony, sarcasm
- Modeling and annotating extra-propositional aspects of meaning
- Scope resolution
- Detection of non-factual information
- Changes of the factual status of events within a text/message and within 
collections of texts/messages
- Discourse phenomena related to extra-propositional aspects of meaning
- The impact of extra-propositional aspects of meaning in NLP tasks: sentiment 
analysis, text mining, textual entailment, information extraction, machine 
translation, paraphrasing
- Implicit expression of extra-propositional meaning
- Multimodal expression of extra-propositional meaning
- Author profiling based on extra-propositional aspects of meaning
- Extra-propositional aspects of meaning across domains and genres

SUBMISSIONS

Authors are invited to submit short papers on original, unpublished work in the 
topic area of this workshop. All submissions must conform to the official ACL 
2012 style guidelines. Formatting instructions and the ACL 2012 Style Files can 
be found at http://www.acl2012.org/call/sub01.asp .

Short papers may consist of up to four (4) pages of content, and two (2) 
additional pages of references. The following types of papers are appropriate 
for a short paper submission:

1. A small, focused contribution
2. Work in progress
3. A negative result
4. An opinion piece
5. An interesting application nugget


The reviewing of the papers will be blind and the papers should not include the 
authors' names and affiliations. Each submission will be reviewed by at least 
three members of the program committee. Accepted papers will be published in 
the workshop proceedings.

Papers should be submitted no later than April 26, 2012, via the following 
submission site:
