Identifying product taxonomy from a product abbreviation is currently performed manually and consumes lot of time and effort. Hence, embodiments of present disclosure provide an automated method for identification of product taxonomy from product abbreviation. First, a brand name of product abbreviation is predicted using a Large Language Model (LLM) and a brand list. Then, possible expansions of the abbreviation are generated based on the brand name using acronym expansion dictionary. Among the generated possible expansions, a relevant one is identified using the LLM. Later, web scraping and web search techniques are applied on the relevant expansion to obtain associated top k matches of a supergroup, a product group and module of the predicted relevant expansion. Finally, product taxonomy is predicted based on the top k matches using a LLM augmented taxonomy classification by Retrieval Augmented Generation.
