A Unified Model for Reverse Dictionary and Definition Modelling. (arXiv:2205.04602v1 [cs.CL])

We train a dual-way neural dictionary to guess words from definitions
(reverse dictionary), and produce definitions given words (definition
modelling). Our method learns the two tasks simultaneously, and handles unknown
words via embeddings. It casts a word or a definition to the same
representation space through a shared layer, then generates the other form from
there, in a multi-task fashion. The model achieves promising automatic scores
without extra resources. Human annotators prefer the proposed model's outputs
in both reference-less and …
