Concrete sentence spaces

Edward Grefenstette, University of Oxford

Clark, Coecke and Sadrzadeh (2007,2008,2010) have developed a categorical framework relating grammatical analysis to distributional semantic modelling of language meaning, in an effort to incorporate syntactic information into semantic composition operations. They present hand-specified truth-theoretic vectors as examples, leaving it for future work to determine how the semantic vectors used in this framework could be obtained from a corpus. This talk presents a proposed quantitative solution to this problem, showing how concrete semantic spaces can be constructed from a corpus for use within this rich new formalism. This paper was produced based on work completed with Sadrzadeh, Pulman, Clark and Coecke.
