In this research, Roman Urdu to Urdu Translator (RUTUT) is proposed that consists of preprocessing methods, rule-based character substitution and Unicode based character mapping techniques. Today most of the modern technologies like computers and mobile phones using English script, due to this local Urdu user has to use English letters to type Urdu script that is Roman Urdu. A survey acknowledges that 300 million people are speaking Urdu and about 11 million speakers in Pakistan from which maximum users prefer Roman Urdu for the textual communication. In pronunciation, both are the same but different in spelling and have different shapes of the alphabet. Urdu language written in English alphabets for communication is known as Roman Urdu. The outcome of this algorithm proved the efficiency and significance as compare to other models and algorithms which work for transliteration of Raman-Urdu to Urdu on context.
Display the first encoded and converted instance and set it to the default if there is not a single instance of the match is found and then adjust the given ambiguous word to their desire location according to their context. The highest frequency words are displayed if more than one match found in the lexicon. If match found, then display the word in the text editor. The algorithm work like, convert the encoding roman words into the words in the standard Urdu script and match it with the lexicon. In this paper, we propose an algorithm which effectively solve the transliteration issues. The objective of this work is to improve the context base transliteration of Roman-Urdu to Urdu script.
Mostly Urdu speaker prefer to use Roman-Urdu for different applications, because mostly user is not familiar with Urdu language keyboard. For writing Urdu characters as an input, there are many layouts which are already exist. Roman alphabets are the most commonly used for transliteration of languages, which have non-Latin scripts. Most of the Asian languages like Arabic, Urdu, Persian, Chains and Korean are written in Roman alphabets. Since last many years there are many tools and techniques that have been developed to support the writing of language script. Now a day computer is necessary for human being and it is very useful in many fields like search engine, text processing, short messaging services, voice chatting and text recognition.
