This paper presents applications of five famous learning methods for Thai phrase break prediction. Phrase break prediction is particularly important for our Thai text-to-speech synthesizer (TTS), where input Thai text has no word and sentence boundary. The learning methods include a POS sequence model, CART, RIPPER, SLIPPER and neural network. Features proposed for the learning machines can be ...

The purpose of this study was to assess the current status of suicide behavior and to examine the association between hopeless feelings, suicidal behavior and components of the WHO Quality-of-Life-BREF instrument among college students (n=1,217) in China, Thailand, and Korea. Results showed 3.7% Thai, 10% Chinese, and 13.2% Korean students exhibited suicidal behavior in the past 12 months. Most...

Steganography, or communication through covert channels, is desirable when the mere existence of an encrypted message might cause suspicion or provide useful information to eavesdroppers. Text is effective for steganography due to its ubiquity. However, text communication channels do not necessarily provide sufficient redundancy for covert communication. We propose a novel steganographic embedd...

This paper presents steps in accessing Thai phoneme distribution from large-scale written Thai corpora. The data were from 12 text genres from InterBEST [1], considered the biggest Thai corpora. Each word was transliterated using the grapheme-to-phoneme software [2]. Then, frequency of words, frequency of 81 Thai phonemes in each genre, and the 95% CIs of average occurrences of each phoneme wer...

This article investigates as an early work on speech recognition of Thai named-entities, which is a crucial out-of-vocabulary word problem in broadcast news transcription. Motivated by an analysis on Thai-name structure, a statistical class-based language model is applied on multiple-sized subword units with a constraint on subword positions. Subwords can be defined automatically by their stati...

During a year from 1999 to 2000, a total of 247 blood samples were collected from 214 cattle and 33 water buffaloes in 16 distinct geographical locations of Thailand and analyzed by allele-specific PCR amplification of major piroplasm surface protein (MPSP) genes of benign Theileria parasites. Four allelic MPSP gene types were determined namely C-type, I-type, B-type and Thai-type, which were o...

CCR5, a chemokine receptor, is the principal coreceptor for macrophage-tropic HIV-1 which is the most important variant for viral transmission. It has been demonstrated that a homozygous genotype of a 32-bp deletion in CCR5 gene (delta32CCR5) shows a high degree of resistance to HIV-1 infection. To demonstrate that delta32CCR5 does exist in Thai natives, the CCR5 genotypes and allelic frequenci...

This paper presents a method of building a gold standard test set of Thai WordNet. The results of this research can be utilised for evaluating or comparing the results from different approaches of Thai WordNet construction. In this research, a part of Thai WordNet is carefully handcrafted from Common Base Concepts’ FirstOrderEntities with five translation resources. However, we found that to bu...
