COGNITIVE TECHNOLOGIES VECTOR SEMANTICS - AND...

This open access book introduces Vector semantics  which links the formal theory of word
vectors to the cognitive theory of linguistics. The computational linguists and deep learning
researchers who developed word vectors have relied primarily on the ever-increasing
availability of large corpora and of computers with highly parallel GPU and TPU compute engines
and their focus is with endowing computers with natural language capabilities for practical
applications such as machine translation or question answering. Cognitive linguists investigate
natural language from the perspective of human cognition  the relation between language and
thought  and questions about conceptual universals  relying primarily on in-depth investigation
of language in use. In spite of the fact that these two schools both have 'linguistics' in
their name  so far there has been very limited communication between them  as their historical
origins  data collection methods  and conceptual apparatuses are quite different. Vector
semantics bridges the gap by presenting a formal theory  cast in terms of linear polytopes 
that generalizes both word vectors and conceptual structures  by treating each dictionary
definition as an equation  and the entire lexicon as a set of equations mutually constraining
all meanings.
