Abstract: A system and method for machine translation-based spelling correction is provided. The method includes receiving, by a processor associated with a system, a query from a user via an electronic device; analysing, by the processor, via an encoder, a fixed dimensional representation of the source sequence for each time step or a query token corresponding to the source sequence; generating, by the processor, via a decoder, a target token corresponding to the query token, based on the fixed dimensional representation; mapping, by the processor, via an attention model, one or more different source sequence representation and one or more relevant source sequence representation, corresponding to each of the target token generated by the decoder at each time step; and outputting, by the processor, one or more query-level candidates with corrected spellings corresponding to the received query, based on mapping.
