About the Workshop
During the last decade, semantic representation of text has focused on extracting propositional meaning, i.e., capturing who does what to whom, when and where. Several corpora are available, and existing tools extract this kind of knowledge, e.g., role labelers trained on PropBank or NomBank. But propositional semantic representations disregard significant meaning encoded in human language. For example, while sentences (1-2) below share the same propositional meaning regarding verb carry, they do not convey the same overall meaning. In order to truly capture what these sentences mean, extra-propositional aspects of meaning (ExProM) such as uncertainty, negation and attribution must be taken into account.
The Extra-Propositional Aspects of Meaning (ExProM) in Computational Linguistics Workshop focuses on a broad range of semantic phenomena beyond propositional meaning, i.e., beyond linking propositions and their semantic arguments with relations such as AGENT (who), THEME (what) and LOCATION (where).
ExProM is pervasive in human language and, while studied from a theoretical perspective, computational models are scarce. Humans use language to describe events that do not correlate with a real situation in the world. They express desires, intentions and plans, and also discuss events that did not happen or are unlikely to happen. Events are often described hypothetically, and speculation can be used to explain why something is a certain way without a strong commitment. Humans do not always (want to) tell the (whole) truth: they may use deception to hide lies. Devices such as irony and sarcasm are employed to play with words so that what is said is not what is meant. Finally, humans not only describe their personal views or experiences, but also attribute statements to others. These phenomena are not exclusive of opinionated texts. They are ubiquitous in language, including scientific works and news as exemplified below:
In its 2016 edition, the ExProM workshop aims at bringing together scientists working on ExProM within computational linguistics. The goal is to attract researchers interested in theoretical frameworks, annotation schemas, modeling and implementing real systems, as well as analyzing the impact of ExProM in natural language processing applications. The workshop also aims at building a bridge between theoretical and computational linguistics.
Topics of interest can be found in the Call for Papers.
ExProM-2016 is a follow-up of two previous workshops: ExProM 2015, Negation and Speculation in Natural Language Processing (NeSp-NLP 2010) and ExProM 2012.
