In the Workshop on the Annotation of Modal Meaning (WAMM), we aim to bring together researchers from a variety of backgrounds with interest in the design and development of resources for the sophisticated annotation of modal meaning in text (as expressed by modal auxiliaries, modal adjectives, and attitude verbs).
The annotation of modal meaning presents a number of wide ranging problems, relating to the choice of features to be annotated, the scopal interaction of modals with other elements, and the subtlety of the distinctions to be drawn among modality types. Modals tend to be highly ambiguous, with senses that are subtly distinct and overlapping. There are also pervasive contextual pressures on interpretation, as well as grammatical constraints operative in particular syntactic configurations. The goal of this workshop is to provide a context for discussion of the challenges raised by the annotation of modal meaning (in various languages and textual genres), as well as the application of modally annotated corpora to theoretical investigation and to practical tasks like textual entailment, factuality and sentiment analysis.

The first Computational Semantics in Clinical Text (CSCT) workshop is a forum for the exploration and application of medically-oriented computational semantics.
Clinical text has unique semantic and pragmatic characteristics — prototypically describing a physician-patient encounter with entities and events in the real world. Furthermore, large-scale semantic resources (e.g., UMLS Metathesaurus) are well-developed and frequently used, text corpora are increasingly available (e.g., i2b2 NLP Challenge data), and the possibility of tangible medical benefit is of broad interest. These characteristics make the medical domain an ideal proving ground for computational semantics theory and practice.

In the Ninth Joint ACL-ISO Workshop on Interoperable Semantic Annotation (ISA-9) we aim to bring together researchers interested in the annotation of semantic information as expressed in text, speech, gestures, graphics, video, and in multiple modalities combined.Examples of semantic annotation include notably the markup of events, time, space, dialogue acts, discourse relations, and semantic roles, for which the ISO organization pursues the establishment of standards in order to promote and support the creation of interoperable semantic resources. The workshop provides a platform for discussing recent work in ongoing projects in ISO and elsewhere, for exchanging information about experiences in creating and applying semantically annotated resources, for bringing in new ideas and perspectives relating to semantic annotation and interoperability, and for discussing semantic annotation in relation to other aspects of language processing.

This workshop aims to foster the integration of formal and distributional semantics, building on their complementary strengths. Its focus is on combining distributional representations with model-based theories in a way that gives formal semantics a better handle on lexical semantics, while still preserving the aspects of formal semantics that have made it useful as a description of meaning in natural languages. From model-based theories, we wish in particular to retain the tight syntax-semantics interface for phenomena such as quantification, scope, modification and semantic roles, the notions of truth and extension, and the modelling of inference, at both the levels of lexical items and propositions. Beyond the goal of better embedding lexical information in formal semantic representations, the probabilistic aspects of distributional models could be investigated in order to handle cases where truth theory falters (e.g., truth of generic statements). More generally, the workshop is open to new ideas about aspects of meaning beyond the level of truth values, and on how distributional semantics may contribute to the notion of intension.

The development of a wide class of so-called situated systems such as robotics, virtual characters, and Geographic Information Systems is heavily dependent on the existence of adequate models of spatial language in order to allow users to interact with these systems when standard graphical, textual, or tactile modes of communication are infeasible or inconvenient.
While early models of spatial term semantics relied on geometrically motivated formal representations, it is now widely recognized that spatial term meaning is also dependent on functional and pragmatic features. Consequently, representations of spatial term semantics must accommodate geometric, functional and pragmatics aspects of situated meaning. The aim of this workshop is to draw together the often orthogonal views on formal symbolic and situated spatial language in order to foster theories and representations which do justice to the complexity and situated nature of spatial language use.
The CoSLI-3 workshop welcomes contributions dealing with any of the topics relevant to the main IWCS conference that address cognitive, symbolic, and situated theories and representations of spatial language. We particularly welcome contributions dealing with accounts that bridge the gap between formal representations and situated systems.
