The Fourth International Conference on Digital Information and Communication Technology and its Applications (DICTAP2014) May 6-8, 2014, University of the Thai Chamber of Commerce, Bangkok, Thailand Thai Language Processing and Its Summarization Applications Thanaruk Theeramunkong Sirindhorn International Institute of Technology, Thammasat University 131 Moo 5 Tiwanont Rd. Bangkadi Muang Pathumthani 12000 thanaruk@siit.tu.ac.th This presentation describes a series of works in Thai language processing and its applications to summarization. In the series, four areas explored are Thai word segmentation, Thai named entity (NE) corpus construction and NE recognition, relation discovery in Thai news texts, and Thai text summarization. Similar to several Asian languages including Chinese, Japanese and Korean, there is no explicit word boundary in Thai written text. Furthermore, a Thai text also has no phrase boundary and no sentence boundary with flexible phrase and sentence structure. This characteristic triggers several issues in processing such Thai running texts, particularly Thai word segmentation and name entity recognition, which are fundamental essential tasks in order to analyze or understand Thai texts. Towards Thai text summarization in news collection, techniques to extract relations among Thai texts and summarize them to create a summary are explored and reported.
