Language Sense and Ambiguity in Thai

Since Thai writing system has no explicit word and sentence boundaries, language sense in Thai depends on how we segment them. Disambiguation by grammars cannot handle all problems because many exceptions occur in the language. Machine learning technique is then introduced to cope with the ambiguity problems. This technique, however, needs good corpora to learn. In this paper, the fundamental problems in Thai natural language processing are expressed and the research topics on problem solving are explored.
