Deriving meanings of words in a first language from morphology of synonyms in a second language

Abstract

A semantic analyzer uses the morphological semantics of Sanskrit to extract numerical representations, or embeddings, from English words. The analyzer finds Sanskrit synonyms for the English input word and deconstructs them into their constituent Dhatus, or morphological units, using Sanskrit morphological rules known as Pratyayas. The meanings of the Dhatus are then used to disambiguate the meaning of the input word. These Dhatu constituents describe the semantic attributes of the word's denotation, forming an embedding of the input word. This low-dimensional vector representation of the word's meaning can be used for various tasks requiring natural language understanding. The Dhatu vectors define a logic of natural-language words, capturing specific semantic attributes to support semantic models with improved interpretability and reasoning power.
