Analyzing Tagore's Emotion With the Passage of Time in Song-Offerings: A Philosophical Study Based on Computational Intelligence

Abstract

The emotions of humans can be observed through tears, smiles, etc. The emotion of poets is reflected through poetry/songs. The works of a poet give philosophical insights about the beauty and mystery of nature, socio-economic conditions of that era, besides his personal state of mind. In the proposed work ‘Song- Offerings': A collection of poems and songs composed by Rabindranath Tagore, for which, Tagore received the Nobel Prize for literature in 1913, has been analyzed. Earlier, most of the research work on Song-Offerings was based on Zipf's law or bibliometric laws. This article analyzes the changes in Tagore's emotion in Song-Offerings with the passage of time (1895-1912). Emotions are analyzed based on the Arousal-Valence Model. To analyze the arousal state, ‘Plutchik's' emotion model has been employed and to find the valence, a Fuzzy-based model has been engaged. The work reveals that the emotions of the poet gradually mellows with the passage of time barring some transitional time, nevertheless, poet submission towards almighty remains unchanged during this period.
