Compared with other language forms, journalese, which is characterized as formal, serious, brief, and standard, in Chinese written texts, carries rich information using few words. Expressing textual meanings, especially personal emotions, by means of appropriate words is quite important in Chinese writing. In teaching Chinese writing, it is easier to compose appropriate texts if teachers and learners interpret emotion words through sense divisions, semantic features, related words, and collocations. This study aimed to build a Chinese emotion lexicon that distinguishes emotion expressions in contexts through the classification of semantic features, as well as provides information via related words and collocations. Moreover, this study applied the characteristics of Chinese emotion words to teach Chinese writing with the aim of improving learners’ writing.
