Distributional semantic models (DSMs) are based on the
assumption that the meaning of a word can (at least to a certain
extent) be inferred from its usage, i.e. its distribution in
text. Therefore, these models dynamically build semantic
representations "in the form of multi-dimensional vector
spaces" through a statistical analysis of the contexts in
which words occur.
With their distributed vector-space representations, DSMs
challenge traditional symbolic accounts of conceptual and
semantic structures. However, their true ability to address key
issues of lexical meaning is still poorly understood, and will
have to be carefully evaluated in linguistic and cognitive
research.
This course aims to equip participants with the necessary
background knowledge for carrying out such research. In addition
to the mathematical foundations of DSMs and their application to
semantic analysis, we will put particular emphasis on relating
the computational models to fundamental issues of semantic
theory.
