A considerable amount of research has been done on the processing of Malaysian and Indonesian languages offering a variety of Computational Linguistics (CL) and Natural Language Processing (NLP) resources (dictionaries, thesauri, monolingual/parallel corpora etc.), tools (morphological analysers/generators, stemmers, spelling checkers, syntactic parsers, etc.) and applications (machine translation, information extraction, information retrieval, etc.). All these valuable language resources, tools, and services are most of the time ignored by the public and often not known by the researchers and students working on these languages.

This Fourth MALINDO Workshop aims to bring together researchers and practitioners, representing different perspectives, to share and to exchange their ideas on the processing of Indonesian and Malaysian languages.

Thus, the organisers of the workshop want to highlight the effort and promising works done on the processing of Malaysian and Indonesian languages in order to attract more students to the CL and NLP fields and also to let all the NLP communities in this World be aware of their existence. The MALINDO workshop is organized by Universitas Indonesia (Depok, Indonesia), the National University of Singapore (NUS, Singapore), and Multimedia University (MMU, Cyberjaya-Malacca, Malaysia).
