Abstract: With the development of the web technologies in Xinjiang,more and more websites for Uyghur people are on line.Due to the historical reasons,the Uyghur language has many different forms of characters,such as Uyghur ErebYziqi (UEY),Uyghur Latin Yziqi (ULY),and Uyghur SirilYziqi (USY).Current Uyghur search engines only support UEY,however,the most common used characters in international communication are the ULY and USY.Therefore,how to design a search engine to support the multi-characters of Uyghur will be a big challenge for the Uyghur information retrieval area.The related breakout may affect the “The Belt and Road Initiative” deeply.This paper stu-died the converting technologies between UEY,ULY and USY,and proposed the corresponding converting algorithms based on the Unicode coding system.This paper also implemented a uniform converting prototype system to retrieve the contents of UEY webpages through the ULY and USY.We verified our methods converting different characters of Uyghur precisely and smoothly in the experiments.The search results by using ULY or USY reach the same rank of UEY based search engines in our prototype system.
