3.2) The Emotion Classifications
In our project, we have classified emotions into six categories, namely anger, disgust, fear, happiness, sadness, and surprise, based on Paul Ekman and his colleagues' cross-cultural study from 1992. We then utilize the GPT-3.5 model to rank each translated poem against these six categories. Each poem is assigned a numerical value denoting its strength in each emotion, and we normalize the sum of these rankings to equal 1. This approach is grounded in our belief that emotions are multi-dimensional and complex, and cannot be reduced to a single dimension or classification. By utilizing multiple categories and ranking each poem against these categories, we can gain a more nuanced understanding of the emotional content of these poems.
While some poems express multiple emotions, we found that no two emotions are entirely contradictory. For example, Li Po's "Drinking Song" expresses both happiness and sadness. Despite the poem's focus on drinking with friends, Li Po wrote it during a difficult time in his life. Waley's translation effectively captures this emotion, subtly conveying Li Po's desire to "drive away the sorrows of a thousand years" through his drinking. Therefore, we have created corridors dedicated to each emotion, even if some poems express multiple emotions. This approach enables us to compare how a specific emotion is expressed across different poems, with poems that express multiple emotions appearing in multiple corresponding corridors.
