“…In contrast, this paper proposes a new method called OMLML that is usable in various applications and fields. In comparison with methods using just machine learning or lexicon to mine opinions such as Puri et al (2018), Bhatnagar et al (2018), Tudoran (2018), Mostafa (2018), Karami et al (2018), Yun et al (2018), Narayan et al (2018), Nuortimo and Härkönen (2018), Souza et al (2018), Rozi et al (2018), Akhmedova et al (2018), Solanki et al (2019) and Kang et al (2018), the method applied for users' opinions mining in this paper combines a machine learning-based method and a lexicon-based method in order to classify opinions and sentiments with more accuracy. In addition, in this paper to create a model of mining based on machine learning and to improve accuracy and performance of the opinion mining method, an improved neural-fuzzy network is proposed.…”
