Resumen
Sindhi is one of the historical languages which is widely used in all over the world, but especially in the province of Sindh-Pakistan. Sindhi language has its own script and written by the right-handed. Nowadays the use of Sindhi different platforms is increasing, but especially for communication. The majority of the people of Sindh province read, write and speak very well, but they face the problem in text communication while using different communication platforms. However, the users of computer and mobile phone feel trouble/difficulty during the uses of the Sindhi script in typing of text messages, tweets and comments while using different platforms in computer and mobile phone. Natural Language Processing (NLP) is one of the better options for the solution of these problems of text communication on different platforms. For the proper solution of text communication issues, Romanized Sindhi text is used instead of Sindhi text. Romanized text writing is easier than the Sindhi text writing because in Sindhi text writing needs the special type of keyboard while writing of Romanized text no need of special type of keyboard. For the writing of Romanized Sindhi text, rules are defined in this paper which provides easiness during writing and understanding of the text. Romanized Sindhi Rules (RSR) are simple and easy to understand the meaning of the text and provide fast communication (text). This study is also helpful for further research in the Romanized Sindhi text by using different approaches and provides easiness in communication.
