The invention discloses a fusion
semantic vector space mapping-based translation
ambiguity term accurate matching method, which comprises the following steps of: S1, obtaining source language
ambiguity terms, context texts and a target language candidate translation
list, and extracting domain tags and term matching features to form a multi-
modal data set; s2, using improved XLM-R model coding to generate term-level,
sentence-level and translation-level semantic vectors; s3, training a
dynamic mapping matrix based on a bilingual parallel corpus, and aligning source side vectors to a shared
semantic space; s4, fusing the source-side basic vector and the multi-dimensional features through a double-channel attention fusion network, and generating source-side and translation-side comprehensive semantic vectors; s5, introducing term-context attention weight to correct
cosine similarity; and S6, outputting an optimal translation through normalized sorting and part-of-speech secondary judgment. According to the method, multi-field ambiguous term accurate matching is realized, the term translation precision and efficiency in professional fields are improved, and the requirements of high reliability of term translation in the fields of
medicine, machinery, computers and the like are met.
