Language and Semantic Technology Research Team (LST)


As a specialized laboratory for natural language processing (NLP) and semantic technology, we are driven to build and strengthen a technological foundation for the processing and automatic understanding of Thai language. Our research of interest includes the collection and construction of linguistic resources, the development of fundamental NLP service platforms, fundamental NLP tools (e.g. electronic dictionaries, word segmentation, parts-of-speech tagging, machine translation, and semantic web). We also employ NLP and semantic technology for advanced knowledge management in local cultural domains.



We endeavor to leverage the research and development of natural language processing and semantic technology in Thailand.
