The Unified Han Characters Retrieval System Based on Romanized Phonetic Transcriptions

[[abstract]]For languages with characters,it is critical to design the effective retrieval system between their phonetic transcriptions and corresponding characters.In Taiwan society,Mandarin,Taiwanese and Hakka are three major and the most popular dialects of Hart languages spoken. Their writing systems are all in Hart characters and also with their respective Romanized phonetic transcription.In this paper,we propose a minimal perfect hashing function to 4135 unified Mandarin,Taiwanese and Hakka existing Romanized phonetic transcriptions to their corresponding Hart characters.Compared to the hashing designs based on the Chinese remainder theorem for various data sets,the proposed design is shown to be superior in space utilization. This novel result is expected to make possible widespread utilization of Chinese dialects in mobile learning devices efficiently.
