Transfer learning for cross-modal sentiment analysis – Complete Phd and Masters Thesis

[ad_1]

Introduction

In recent years, sentiment analysis has gained significant attention in various application domains such as social media, e-commerce, and customer feedback analysis. Sentiment analysis aims to identify and extract subjective information from textual data to determine the sentiments, opinions, and emotions expressed by users. However, traditional sentiment analysis techniques often focus solely on textual data, neglecting the valuable information present in other modalities such as images, videos, and audio.

Cross-modal sentiment analysis, which involves analyzing sentiments across different modalities, has emerged as a promising research direction to capture a more comprehensive understanding of user sentiments. By integrating information from multiple modalities, cross-modal sentiment analysis can enhance the accuracy and robustness of sentiment analysis systems. Transfer learning, a machine learning technique that leverages knowledge learned from a source domain to improve performance in a target domain, has shown great potential in cross-modal sentiment analysis by transferring knowledge across different modalities.

This thesis aims to explore the use of transfer learning for cross-modal sentiment analysis, specifically focusing on integrating textual and visual modalities. By leveraging the complementary information present in text and images, this research seeks to enhance the performance of sentiment analysis systems and provide a more holistic understanding of user sentiments.

Thesis Overview on Transfer Learning for Cross-Modal Sentiment Analysis

Sentiment analysis has become a crucial area of research in natural language processing and machine learning, with applications in social media monitoring, customer feedback analysis, and opinion mining. Traditional sentiment analysis techniques focus primarily on textual data, ignoring the valuable information present in other modalities such as images and videos. Cross-modal sentiment analysis aims to bridge the gap between different modalities to provide a more comprehensive understanding of user sentiments.

Transfer learning, a machine learning technique that leverages knowledge learned from a source domain to improve performance in a target domain, has shown great potential in cross-modal sentiment analysis. By transferring knowledge across different modalities, transfer learning can enhance the accuracy and robustness of sentiment analysis systems. This thesis explores the use of transfer learning for cross-modal sentiment analysis, specifically focusing on integrating textual and visual modalities to improve sentiment analysis performance.

The thesis is structured into five chapters, starting with an introduction that provides background information on sentiment analysis, cross-modal sentiment analysis, and transfer learning. The literature review chapter presents an overview of existing research in sentiment analysis, cross-modal sentiment analysis, and transfer learning, highlighting the challenges and opportunities in this research area. The research methodology chapter discusses the research design, data collection, feature extraction, model selection, and evaluation methodology used in the study.

The discussion of findings chapter presents the results of the experiments conducted to evaluate the performance of transfer learning models in cross-modal sentiment analysis. The chapter also analyzes the impact of textual-visual integration on sentiment analysis and compares the proposed approach with state-of-the-art methods. Lastly, the conclusion and summary chapter summarizes the findings of the study, outlines the contributions of the research, and provides recommendations for future research directions in transfer learning for cross-modal sentiment analysis.

Overall, this thesis contributes to the advancement of sentiment analysis research by exploring the use of transfer learning for cross-modal sentiment analysis. By integrating textual and visual information, the study aims to enhance the accuracy and robustness of sentiment analysis systems and provide a more holistic understanding of user sentiments across different modalities.
