ACL Workshop ExProM 2012
Extra-propositional aspects of meaning in computational linguistics

Organised by the University of Antwerp and Saarland University
Colocated with ACL 2012

13 July 2012, Jeju Island, Korea


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.

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.


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


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. Formatting instructions and the ACL 2012 Style Files can be found at .

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 March 18, 2012, via the following submission site:
