Semantic Hilbert Space for Text Representation Learning

1 code implementation26 Feb 2019 Benyou Wang, Qiuchi Li, Massimo Melucci, Dawei Song

To address this issue, we propose a new framework that models different levels of semantic units (e. g. sememe, word, sentence, and semantic abstraction) on a single \textit{Semantic Hilbert Space}, which naturally admits a non-linear semantic composition by means of a complex-valued vector word representation.
