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

Papers are invited for the one-day workshop to be held in Jeju Island, 
Korea, 0n 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 full papers on original, unpublished work in 
the topic area of this workshop. All submissions must conform to the 
official ACL 2012 style guidelines and should not exceed 8 pages.
