1. Introduction
The use of emoji as a text-based expression is the novel form of investigation in recent research areas on artificial intelligent (AI). An emoji database containing emoji pack can contain a set of custom emoji designed with a specific signature tune in mind. In AI, they are used as form of emotion expression from a user to the interface (Lu et al., 2016; Lisetti and Nasoz, 2002; Lisetti and Schiano, 2000). For AI adaptive systems, an emotion recognition scheme is built to understand user expression in an online business webpage on marking site or set as an objective view towards client products. The major user attributes to extract is the user emotion. The basic emotions are expressed when interrelating and mixing with other individuals online. Studying how to understand user expression can be a tedious task, technologies through AI are used to produce emotion recognition systems to optimise and reduce guess work (Pauletto et al., 2013; Isman et al., 2021; Zhang et al., 2009; Volioti et al., 2018). The research question is: What are emotion recognition systems and its benefits to online user interaction sequencer as a contribution to future AI? Most work that is focused on AI-modified systems are sometimes theoretical suggestions for exhaustive optimisation of AI control systems in a business environment, and there is a need for the dynamic and adaptive theoretical framework with logical design format. Table 1 shows related work in the AI-oriented field where some are mostly based on user-defined attributes and some on theoretically systematic ideas for possible suggestions towards AI. Emotion recognition as part of contributions to AI is one of the advanced facial recognition expertise systems that have been developed and is progressed through the years (Zednik, 2021; Kiritchenko et al., 2021; Nakase et al., 2021; Roberts et al., 2021). The emotion recognition software is used to allow certain program to process the expressions on human's face, mostly using radical image dispensation; it functions like the brain of a person which is capable of recognising the emotions of an individual, its only limitations is recognising subtle expression relatively complex to detect (Busuioc, 2021; Shorten et al., 2021). Another question that comes to mind is: What...
