Tod Allman (Ph.D. & MA in Linguistics, and an MS and BS in Engineering) is an Adjunct Professor, Department of Applied Linguistics, Graduate Institute of Applied Linguistics, Dallas, TX. He has been working in the field of Natural Language Generation for the past twenty years. He and his colleagues have designed and developed a linguistically based natural language generator named Translator's Assistant (TA). TA produces high quality draft translations in a wide variety of languages, particularly minority and endangered languages. Linguists may use TA to simultaneously document a language, and also produce initial draft translations of significant texts in the language. When experienced mother-tongue translators edit the drafts produced by this system into publishable texts, their productivity is typically quadrupled without any loss of quality. TA incorporates extensive typological, semantic, syntactic, and discourse research into its semantic representational system and its transfer and synthesizing grammars. Tod has worked with linguists and mother-tongue speakers in order to develop lexicons and grammars for a variety of languages including Korean, Kewa (Papua New Guinea), Jula (Cote d'Ivoire), Angas (Nigeria), and Chinantec (Mexico). He hopes that the texts generated by TA will empower the speakers of these languages by providing them with vital information which helps them live longer, healthier, and more productive lives, and also enables them to participate in the larger world.

Toward an Optimal Multilingual Natural Language Generator: Deeper Source Analysis and Shallower Target Analysis

Translator's Assistant (TA) is a large scale multilingual natural language generator (NLG) designed and developed entirely from a linguist's perspective. TA has been tested with English, Korean, Kewa (Papua New Guinea), and Jula (Cote d'Ivoire), and proof of concept grammars have been developed for a variety of other languages. TA has generated initial draft translations of texts in each of the test languages, and when experienced mother-tongue translators edit those drafts into publishable texts, their productivity is typically quadrupled when compared with manual translation.

An optimal NLG will be able to generate high quality texts in a wide variety of languages with minimal knowledge of the target language grammars. In order to increase the quality of the drafts generated by TA, deep source analysis techniques have been adopted. And in order to minimize the target language knowledge that is required to generate the drafts, a new approach to grammar development has been designed into LA's synthesizing grammar. This paper will describe several of the source analysis conventions that have been adopted during the development of TA's semantic representations, and it will also present examples of the new type of synthesizing rule that was added to TA's grammar. The adoption of deep source analysis techniques combined with shallow target analysis has proven to be a very efficient model.

Chiu-yu Tseng (Ph.D. in Linguistics, Brown University, U.S.A., 1981) is a Research Fellow and Director at the Institute of Linguistics, Academia Sinica, Taiwan. She was trained in phonetics, but her close collaboration with speech scientists since the early 1980's has led an interdisciplinary orientation that integrates corpus linguistics and computational modeling into acoustic investigations. To facilitate the corpus and computational end in her research orientation, she has constructed two sets of corpora. The Sinica COSPRO (Mandarin Continuous Speech Corpora) and Toolkit (10.58GB total, 7.9GB annotated) which was released it in 2006. The AESOP-ILAS, an international collaboration of the AESOP (Asian English Speech cOrpus Project) consortium (2009—present) of L2 English by Taiwan Mandarin speakers (13.9GB total, 540 speakers, 815 hours). She has been an active contributor to international and regional communities in Chinese Linguistics, Computational Linguistics, Speech Databases and Assessment and Corpus Linguistics, Spoken Language Processing and Speech Communication. She was a founding and life member of IACL, ACLCLP (Association of Computational Linguistics and Chinese Spoken Language Processing) and LST (Linguistic Society of Taiwan), and elected as an Ex officio member for many terms. She also served as Vice Chairperson for for SIG-CSLP, ISCA (Special Interest Group-Chinese Spoken Language Processing, the International Speech Communication Association) for 2 terms (2004-08), and Chairperson for 2 terms (2008-12). She served as the Convener of Oriental-COCOSDA (The International Committee for the Co-ordination and Standardization of Speech Databases and Assessment Techniques) for 6 years (2006-12) was awarded the Antonio Zampolli Prize in 2012 for outstanding contributions to the advancement of language resources and language technology evaluation within human language technologies. Currently, she is serving a 4-yr term (2011-14) as an IAC (International Advisory Council) member of ISCA (The International Speech Communication Association), a 1-yr term (2013-14) as the Vice President of IACL (The International Association of Chinese Linguistics). She will serve a 1-yr term (2015-16) as the President of IACL.

NLP in Practice

What does it take to bring NLP research into commercial products? Who have made it successfully out to market? How can I bring my research out to the market? While many of the NLP research shows promising results, we face great challenges as we bring these results into commercial use.

Ariane Borlongan is Assistant Professor in the Department of English and Applied Linguistics, De La Salle University, Manila,Philippines. His interests are on Philippine English and world Englishes, English linguistics, historical linguistics, sociolinguistics, and language teaching and learning. He wrote A Grammar of the Verb in Philippine English for his dissertation in his Ph.D. in Applied Linguistics from De La Salle University. He is the principal compiler of the Philippine parallel to the Brown University Standard Corpus of Present-Day Edited American English.

Introducing the Philippine Parallel to the Brown Corpus: Compilation Issues and Initial Findings

The compilation of the Philippine component of the International Corpus of English (ICE-PH) in 2004 by Ma. Lourdes Bautista, Jenifer Loy Lising, and Danilo Dayag at De La Salle University has made possible synchronic, apparent-time analyses of Philippine English, and also in comparison with other Englishes; works of this kind can be found in Bautista (2011) and summarized in Borlongan (2013) and Borlongan and Lim (2012). Recently, Ariane Borlongan also at De La Salle University (partially) completed the compilation of the Philippine parallel (Phil-Brown) to the Brown University Standard Corpus of Present-Day Edited American English (Brown). The said parallel corpus, representing Philippine English of the 1960s, allows for a diachronic analysis of Philippine English as well as diachronic comparable corpus linguistic analysis (Leech, Hundt, Mair, and Smith, 2009) of American, British, and Philippine Englishes. This paper provides an overview of the Phil-Brown. It presents the methodology of the compilation, the features of the corpus, differences from the Brown corpus, and its limitations. This paper also surveys the recent studies conducted that made use of Phil-Brown. Finally, the paper previews prospects and challenges for Phil-Brown, further development of the corpus, and further research on diachronic changes in Philippine English.
