Recently, effort to obtain various information from the vast amount of social network services (SNS) big data generated in daily life has expanded. SNS big data comprise sentences classified as unstructured data, which complicates data processing. As the amount of processing increases, a rapid processing technique is required to extract valuable information from SNS big data. We herein propose a system that can extract human sentiment information from vast amounts of SNS unstructured big data using the naïve Bayes algorithm and natural language processing (NLP). Furthermore, we analyze the effectiveness of the proposed method through various experiments. Based on sentiment accuracy analysis, experimental results showed that the machine learning method using the naïve Bayes algorithm afforded a 63.5% accuracy, which was lower than that yielded by the NLP method. However, based on data processing speed analysis, the machine learning method by the naïve Bayes algorithm demonstrated a processing performance that was approximately 5.4 times higher than that by the NLP method.

The expansion of the world wide web has led to a huge amount of user generated content over different forums and social media platforms, these rich data resources offer the opportunity to reflect, and track changing public sentiments and help to develop proactive reactions strategies for decision and policy makers. Analysis of public emotions and opinions towards events and sentimental trends can help to address unforeseen areas of public concerns. The need of developing systems to analyze these sentiments and the topics behind them has emerged tremendously. While most existing works reported in the literature have been carried out in English, this paper, in contrast, aims to review recent research works in Arabic language in the field of thematic sentiment analysis and which techniques they have utilized to accomplish this task. The findings show that the prevailing techniques in Arabic topic-based sentiment analysis are based on traditional approaches and machine learning methods. In addition, it has been found that considerably limited recent studies have utilized deep learning approaches to build high performance models.

The importance of online reviews is prevalent as more people access goods or places online and make decisions to visit or purchase. However, such reviews are generally provided by short sentences or mere star ratings; failing to provide a general overview of customer preferences and decision factors. This study explored and broke down restaurant reviews found on Google Maps. After collecting and analyzing 5,427 reviews, we vectorized the importance of words using the TF-IDF. We used a random forest machine learning algorithm to calculate the coefficient of positivity and negativity of words used in reviews. As the result, we were able to build a dictionary of words for positive and negative sentiment using each word's coefficient. We classified words into four major evaluation categories and derived insights into sentiment in each criterion. We believe the dictionary of review words and analyzing the major evaluation categories can help prospective restaurant visitors to read between the lines on restaurant reviews found on the Web.

Purpose: This research delves into the various factors that influence the performance of restaurant businesses on social commerce platforms in Bangkok, Thailand. The study considers both internal and external factors, including but not limited to business characteristics and location. Moreover, this research also analyzes the effects of employing multiple social commerce platforms on business efficiency and explores the underlying reasons for such effects. Research design, data, and methodology: Restaurants can be classified into different price ranges: low, medium, and high. To further investigate, we employed natural language processing AI to analyze online reviews and evaluate algorithm performance using machine learning techniques. We aimed to develop a model to gauge customer satisfaction with restaurants across different price categories effectively. Results: According to the research findings, several factors significantly impact restaurant groups in the low and mid-price ranges. Among these factors are population density and the number of seats at the restaurant. On the other hand, in the mid-and high-price ranges, the price levels of the food and drinks offered by the restaurant play a crucial role in determining customer satisfaction. Furthermore, the correlation between different social commerce platforms can significantly affect the business performance of high-price range restaurant groups. Finally, the level of online review sentiment has been found to influence customer decision-making across all restaurant types significantly. Conclusions: The study emphasizes that restaurants' characteristics based on their price level differ significantly, and social commerce platforms have the potential to affect one another. It is worth noting that the sentiment expressed in online reviews has a more significant impact on customer decision-making than any other factor, regardless of the type of restaurant in question.

The historical turbulence between China and Japan started from the First Sino-Japanese War in 1895, and culminated in Japan's invasion of China during World War Two (the Second Sino-Japanese War) between 1937 and 1945. A series of wars caused huge human and material losses in both countries, and both experienced comprehensive transformations during and after the wars. The impact of this historical turbulence is so long-lasting that it still influences both countries' social psyche. Moreover, it continues casting a long shadow upon the current Sino-Japanese relations. The recent turbulence in Sino-Japanese relations partly stems from the historical turbulence. It is much less violent but can also be emotional and worrisome. It started from the early 1980s (the Japanese history textbook controversy in 1982 and the 1985 anti-Japanese student protests in China), and culminated in the anti-Japanese mass demonstrations in multiple Chinese cities in 2005 (Bush 2010; Gries 2005; Reilly 2012; Stockmann 2010; Weiss 2008). In addition to dramatic demonstrations on streets, there are also other forms of movements, such as war reparations movements, in which Chinese war victims demand reparations from the Japanese state and companies (Rose 2005; Xu and Fine 2010; Xu and Pu 2010). Although the tension has existed for many years and surfaced from time to time, the eruption of the nationwide anti-Japanese movements in China in 2005 still shocked many outside observers. Many scholars have tried to explain the anti-Japanese sentiment within current Chinese society that underlies and drives these social movements. Through careful reexamination of the existing literature, this article proposes an explanation for the anti-Japanese sentiment from a perspective that stresses the shifting state-society interaction in China's Japan policy. Specifically, the totalitarian Chinese state's neglect and suppression of genuine social concerns regarding Japan in earlier years, followed by a relatively liberalized state that tolerates societal participation in Sino-Japanese relations, are an importance source of the anti-Japanese sentiment recently observed in China.
