Abstract(in English) | The method proposed here analyzes the social sentiments from collected tweets that have at least one of 800 sentimental adjectives. By dealing with half-a-day tweets as a document, the method extracts the social sentiments using Latent Dirichlet Allocation (LDA). It captures some sentiments that match our daily sense, although some do not coincide with it. The extracted sentiments, however, indicate lowered sensitivity to changes in time. Using LDA for the representative 72 adjectives to which each of the 800 adjectives maps with preserving the word frequencies permits us to obtain sentiments that show improved sensitivity to changes in time. |
