The Thai character confounding NLP engines

If you've ever attempted to learn Thai, you can assume that this Southeast Asian language is extremely difficult -- if not the most difficult -- for machines to also understand. Thai is a character-based language with numerous quirks that disrupt natural language processing algorithms. Because of these quirks, leading NLP engines fail to understand Thai beyond the surface-level, causing an underwhelming customer experience. First, the language consists of several types of interjection words in a single sentence. Many of these words do not carry any meaning relevant to the sentence's intent; these words are most often used to indicate emotion or an expression of politeness.
