The crowdsourcing method to normalize 'bahasa alay', a case of indonesian corpus

In verbal communication, people use sentences that can be classified into two categories, namely formal and non- formal. The former meets the grammatical standard as prescribed by linguistic rules of the language, while the latter deviates it. In daily communication, however, non-formal sentences are more intensively used because they are more practical and easier to understand. With this deviation, nonformal sentences cause problems in linguistic computation because most linguistic computations use formal languages that already have standard rules. This research aims to develop an Indonesian closed corpus related to airline ticket reservations. The data used to develop the corpus are taken from conversations between customer service staff and consumers in airline ticket reservations. This is a preliminary study to propose and develop a chatbot in airline ticket reservations. The result of this study is the Indonesian closed corpus related to airline ticket reservations to determine the right response for consumers. © 2020 IEEE.
