Representing the semantics of modal verbs (must), adjectives (likely) and nouns (chance), verbs of propositional attitude (believe, want), hedging adverbs (maybe, probably) and other expressions whose meaning is related to non-actual possibilities has been an important domain of research for philosophers of language, logicians, natural language semanticists, and computational linguists for decades.
In recent years, researchers in computational semantics have started to focus their attention on the interpretation of these expressions, as it has become clearer that identifying modal meaning has important consequences for such practical tasks as the computation of textual entailments, factuality status and sentiment analysis. Concurrently, significant theoretical-semantic research has lead to a deeper understanding of the interaction of modal meaning with tense and aspect on the one hand and syntactic structure on the other. Both lines of work have turned to semantic annotation to further their computational and theoretical investigation (Baker et al. 2012, de Haan 2011, Hacquard and Wellwood, to appear). In this workshop, we hope to bring together researchers from a variety of backgrounds with interest in the design and development of resources for sophisticated annotation of modal meaning in text.
The annotation of modal meaning presents a number of wide ranging problems for researchers, relating on the one hand to the practicalities of annotation and on the other to the subtlety of distinctions to be drawn in the modal domain. The very definition of the set of modal words is a difficult matter, raising questions about the differences between prototypical exemplars of the class (should, can) and verbs of propositional attitude (believe, want). Modals tend to be highly ambiguous, with senses that are subtly distinct and overlapping. There are also pervasive contextual pressures on the interpretation of modal expressions, as well as grammatical constraints which limit these contextual pressures in particular syntactic configurations. The complex interaction of grammar, context, and lexical content in the expression of modal meaning makes the task of creating high-quality annotated modal corpora particularly important and challenging. The goal of this workshop is to address these challenges.
Topics of interest include, but are not limited to:
- Classes of modality (modal “flavors”)
and the desirable fine-grainedness of the annotation.
- Source of modality: identifying the agent behind the modal claim.
- Identifying the scope of modal
expressions: what is the proposition that is described as non-actual?
- Representing the interaction of
degree modifiers with modal expressions.
- Polarity, negation, and modality.
- Scopal and relational information in
modal interpretation (modal subordination, situation anaphora).
- Annotation of the semantic scope
between modals and other quantifiers.
- Modal interpretation in conversation:
the representation of the shared beliefs and preferences of
- Multilingual annotation and the
prospects for a unified annotation scheme.
- Modality annotation efforts
- Viability of crowd-sourcing for the
annotation of modality.
- Machine learning of modal features
(e.g., sense disambiguation of modality classes).
- Use of annotated corpora for
translation and other NLP applications.
