The rapid expansion of multilingual digital platforms has made the accurate analysis of user-generated content across different languages and cultural contexts increasingly essential. However, existing methods struggle to maintain consistent performance due to linguistic diversity, morphological complexity, and structural variations in text. Many studies in the literature analysis stages as isolated components, which causes errors in early stages to propagate and negatively affect overall performance. To address these challenges, this study proposes an integrated and multilingual aspect-based sentiment analysis pipeline that encompasses language identification, machine translation, sentiment classification, and topic modelling. The proposed approach evaluates a comprehensive range of models, from statistical methods to transformer-based architectures and Large Language Models, using the M-ABSA and MARC datasets which comprise over one million reviews across 21 languages. The analyses not only assess the final model performance but also examine the relative contributions, limitations, and error-propagation effects of each component in the pipeline. The findings quantitatively reveal how linguistic diversity, noise, and contextual variability in real-world data influence analysis processes, while systematically comparing the behaviour of generative models and traditional approaches under such challenging conditions. Overall, the study underscores the necessity of an end-to-end, integrated analysis pipeline over fragmented solutions and provides a comprehensive methodological and practical contribution to the field of multilingual text processing.
