However, there is currently a lack of research analysing these reviews by airport services using sentimental analysis approaches. This research applies multiclass models based on Aspect-Based Sentimental Analysis to conduct a comprehensive analysis of travellers’ reviews, in which the major airport services are tagged by positive, negative, and non-existent sentiments. Seven airport services commonly utilised in previous studies are also introduced. Subsequently, various Deep Learning architecturesand Machine Learning classification algorithms are developed, tested, and compared using data collected from Twitter, Google Maps, and Airline Quality, encompassing travellers’ feedback on airport service quality. The results show that the traditional Machine Learning algorithms such as the Random Forest algorithm outperform Deep Learning models in the multiclass prediction of airport service quality using travellers’ feedback. The findings of this study offer concrete justifications for utilising multiclass Machine Learning models to understand the travellers’ sentiments and therefore identify airport services required for improvement.  \nKeywords: airport service quality; Deep Learning; Twitter; Google Maps; Airline Quality  \nMSC: 68T07; 68T50  \n1. Introduction  \nThe term “airport services” encompasses a multifaceted array of offerings that collectively contribute to the overall experience of air travellers. The current literature provides various definitions and perspectives on the constituents of airport services, but often emphasises the comprehensive nature of the travellers’ experience within airport facilities. For instance, researchers (e.g., [1]) asserted that airport services encompass a spectrum of amenities and processes, including check-in procedures, security protocols, baggage handling, and terminal facilities. In contrast, other scholars (e.g., [2]), adopted a more nuanced approach to defining airport services. Their focus extended beyond the procedural elements to include the quality of passenger interactions, emphasising customer service, staff responsiveness, and the overall ambiance of the airport environment. This perspective underscores the significance of human-centric factors in shaping travellers’ experience. Additionally, Dhini and Kusumaningrum [3] delved into the concept of airport services asa holistic system that encompassed both tangible and intangible elements. Tangible aspects involve physical facilities and infrastructure, while intangib","cbCaipHnRvPc8pwQ","https://ap.wps.com/l/cbCaipHnRvPc8pwQ","pdf",9464263,1,17,"English","en",105,"# Introduction\n##
