Abstract
By systematically studying the key technologies, system construction and challenges of social media emotion analysis, this paper successfully constructs an efficient social media emotion analysis system. We deeply explore the application of machine learning in emotion analysis, pay special attention to the latest progress of deep learning technology, and construct the basic fr amework of a multimodal emotion analysis model. Subsequently, the construction process of the emotion analysis system in social media is described in detail, including several key steps including system architecture design, data preprocessing, feature extraction, and emotion classification and intensity analysis. In the system architecture design, we clearly define the overall architecture of the system and the functional division of each module to ensure the efficient operation and scalability of the system. In the data preprocessing stage, we adopted advanced text cleaning, word segmentation and stop word removal techniques, as well as image processing and feature extraction methods, to provide high-quality data input for subsequent emotion analysis. In the stage of feature extraction and representation learning, we combined the characteristics of text and multimedia data, extracted and vectorize text features respectively, as well as the feature representation of multimedia data such as image and audio, providing rich feature information for emotion classification and intensity analysis. In terms of emotion classification and intensity analysis, we propose a variety of emotion classification methods based on machine learning and deep learning techniques, and accurately evaluate the emotion intensity through regression analysis methods. It also proposes countermeasures to address the challenges of social media emotion analysis systems, including data preprocessing and cleaning, complex emotion modeling, multilingual and cross-cultural adaptation, and privacy protection technologies. This study aims to construct an efficient and accurate emotion analysis system for social media to provide strong technical support for the purpose of emotional tendency analysis of social media data
