The use of vectors to represent meanings in semantic spaces or feature spaces is also employed in cognitive science. Unrelated to natural language and cognitive science, vectors and vector spaces have been extensively used as models of physical theories and especially the theory of quantum mechanics. Crucial similarities between the vector representations of quantum mechanics and those of natural language are exhibited via bicompact linear logic and compact closed categorical structures in natural language. Exploiting the common ground provided by vector spaces, the proposed workshop will bring together researchers working at the intersection of NLP, cognitive science, and physics, offering to them an appropriate forum for presenting their uniquely motivated work and ideas. The interplay between these three disciplines will foster theoretically motivated approaches to understanding how meanings of words interact with each other in sentences and discourse via grammatical types, how they are determined by input from the world, and how word and sentence meanings interact logically. Topics of interest include (but are not restricted to): Reasoning in semantic spaces Compositionality in semantic spaces and conceptual spaces Conceptual spaces in linguistics and natural language processing Applications of quantum logic in natural language processing and cognitive science Modelling functional words such as prepositions and relative pronouns in compositional distributional models of meaning Diagrammatic reasoning for natural language processing and cognitive science Modelling so-called ‘non-compositional’ phenomena such as metaphor SUBMISSIONS: We welcome two types of submission: - Archival papers of up to 8 pages should report on complete, original and unpublished research. Accepted papers will be published in the workshop proceedings and appear in the ACL anthology. - Extended abstracts (up to 3 pages) may report on work in progress or work that was recently published/accepted at a different venue. Extended abstracts will not be included in the workshop proceedings. Both accepted papers and extended abstracts are expected to be presented at the workshop. Authors must submit non-anonymized extended abstracts or papers by March 26. Both extended abstracts and papers must be formatted according to the IWCS guidelines, and must be submitted via softconf (link available soon). The extended abstracts should not contain an abstract section and may consist of up to 3 pages of content, plus unlimited references. Archival papers may consist of up to 8 pages of content, plus unlimited references. Camera-ready versions of papers will be given one additional page of content so that reviewers’ comments can be taken into account.
