We also noticed that the performance on the dev set is generally slightly better than that on the test set. The Macro-F1 scores of each emotion category are very different from each other: the classification accuracy for emotion Sad is the highest in most of the cases, while the emotion Happy is the least accurately classified by all the models. The performance of SLD and SL are very close to each other, on the dev set, SLD performs better than SL but they have almost the same overall scores on the test set. It shows that the proposed HRLCE model performs the best. We use the majority voting strategy to merge the results from the 9 iterations. ![]() The inferences over dev and test sets are performed on each iteration. Therefore, every model is trained 9 times to ensure stability. Each iteration, 1 fold is used to prevent the models from overfitting while the remaining folds are used for training. We run 9-fold cross validation on the training set. Figure 1: An illustration of the HRLCE model The usage of figurative language, like sarcasm, and the class size’s imbalance adds up to this problematic Chatterjee et al. The need to consider the context of the conversion is essential in this case, even for human, specifically given the lack of voice modulation and facial expressions. One of the main challenges is that one user’s utterance may be insufficient to recognize the emotion Huang et al. Giving the detected emotion, an emotionally intelligent agent would generate an empathetic response.Īlthough its potential convenience, detecting emotion in textual conversation has seen limited attention so far. User is conversing with an automatic chatbot.Įmpowering the chatbot with the ability to detect the user’s emotion is a step forward towards the construction of an emotionally intelligence agent. May reveal important information in social online environments, like ( 2017).Įmotions have been extensively studied in psychology Ekman ( 1992) Plutchik ( 2001). These scores are better than the baselines, especially for subtasks A–C.Recently, emotion classification from social media text started receiving more attention Mohammad et al. The best systems achieved an official score (MAP) of 88.43, 47.22, 15.46, and 61.16 in subtasks A, B, C, and D, respectively. A variety of approaches and features were used by the participating systems to address the different subtasks. Unfortunately, no teams participated in subtask E. A total of 23 teams participated in the task, and submitted a total of 85 runs (36 primary and 49 contrastive) for subtasks A–D. Additionally, we added a new subtask E in order to enable experimentation with Multi-domain Question Duplicate Detection in a larger-scale scenario, using StackExchange subforums. This year, we reran the four subtasks from SemEval-2016: (A) Question–Comment Similarity, (B) Question–Question Similarity, (C) Question– External Comment Similarity, and (D) Rerank the correct answers for a new question in Arabic, providing all the data from 20 for training, and fresh data for testing. We describe SemEval2017 Task 3 on Community Question Answering.
