This paper presents our system developed for the SemEval-2025 Task 11:Bridging the Gap in Text-Based Emotion Detection, on Track A: Multi-label Emotion Detection.Given a target text snippet, predict the perceived emotion(s) of the speaker. Specifically, select whether each of the following emotions apply: joy, sadness, fear, anger, surprise, or disgust. To this end, we focus on English source language selection strategies on four different pre-trained languages models: google-bert,FacebookAI-roberta,dccuchile-bert and distilbert-multi.We experiment with 1) the training set data is analyzed visually, 2) multiple numbers of single models are trained on the training set data, and 3) multiple number of single models for votingweight ensemble learning. We further study the influence of different hyperparameters on the integrated model and select the best integration model for the prediction of the test set. Our submission achieved the good ranking place in the test set.Emotion Macro F1 Score 0.6998 and Emotion Micro F1 Score 0.7374. For the final ranking, organizers will use the Macro F1 score.Even so, my approach has yielded good results.
