| Challenge: | Existing studies on emotion analysis have studied the analysis of basic emotions and sentiment polarity independently. |
| Approach: | They extend the WRIME dataset with basic emotion intensity from both the writer's subjective and reader's perspective to include the Japanese sentiment polarity. |
| Outcome: | The proposed dataset is the first large-scale corpus to annotate both basic emotions and sentiment polarity labels from both the writer’s and reader’s perspectives. |

| Challenge: | Existing studies on emotion analysis use subjective emotional intensity labels by the writers and objective ones by the readers. |
| Approach: | They annotate 17,000 SNS posts with both the writer's subjective emotional intensity and the reader's objective emotional intensity to construct a Japanese emotion analysis dataset. |
| Outcome: | The results show that the reader cannot fully detect the emotions of the writer, especially anger and trust. |

| Approach: | They propose a full pipeline of analysis of a large corpus about a century of public meeting in historical Australian news papers, from construction to visual exploration. |
| Outcome: | The proposed method achieves a high recall rate and an F-score of 87.8% on a historical Australian newspaper database. |
