A considerable amount of research has been done on the processing of South East Asian languages offering a variety of Computational Linguistics (CL) and Natural Language Processing (NLP) resources, tools and applications. All these valuable language resources are most of the time ignored by the public and often not known by the researchers and students working on these languages.

This 5th MALINDO Workshop aims to bring together researchers and practitioners, representing different perspectives, to share and to exchange their ideas on the processing of South East Asian languages such as Indonesia, Laos, Malaysia, Myanmar, Philippines, Thailand, Vietnam etc. The workshop is co-located with the Philippine NNLPRS (National Natural Language Processing Research Symposium) 2011.

Thus, the organisers of the workshop want to highlight the effort and promising works done on the processing of South East Asian Languages 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.

• Language resources development, acquisition, annotation, and representation: dictionaries, thesauri, terminology, lexicons, written and spoken corpora, grammars, ontology.
• CL and NLP tools and techniques: spelling/grammatical/style checkers, morphological analyser, stemmer, lemmatiser, part of speech tagger, chunker, syntactic parser, word sense disambiguation, discourse processing, text and speech alignment, text and speech segmentation, term extraction and recognition, named entity extraction.
• CL and NLP applications: machine translation and translation aids, information retrieval, information extraction, text summarization, term extraction, natural language generation, question translation aids, information retrieval, information extraction, question answering, document categorization, language identification, speech recognition, speech synthesis, character recognition.
