Current Situation of Multimodal Corpora and the Method of Tibetan Corpus Construction

In recent years, the rapid development of artificial intelligence has brought enormous influence to the human social life, and as part of artificial intelligence, affective computing is attracting more and more attention from researchers because it can be applied to many fields such as psychology, sociology and so on. Human beings will express emotion through expression, voice, text and physiological signals, and the development of emotional computing cannot be separated from the support of emotional database. At present, the emotional database is mostly single modality, and there are many deficiencies in the existing multimodal emotion database. Therefore, it is of great significance to construct a more fully prepared multimodal emotion database. This paper summarizes the research status of multimodal corpus in China and abroad, and constructs a more comprehensive Tibetan multimodal emotion corpus.
