Customer sentiment analysis and prediction of halal restaurants using machine learning approaches

Abstract

Purpose There is a strong prerequisite for organizations to analyze customer review behavior to evaluate the competitive business environment. The purpose of this study is to analyze and predict customer reviews of halal restaurants using machine learning (ML) approaches. Design/methodology/approach The authors collected customer review data from the Yelp website. The authors filtered the reviews of only halal restaurants from the original data set. Following cleaning, the filtered review texts were classified as positive, neutral or negative sentiments, and those sentiments were scored using the AFINN and VADER sentiment algorithms. Also, the current study applies four machine learning methods to classify each review toward halal restaurants into its sentiment class. Findings The experiment showed that most of the customer reviews toward halal restaurants were positive. The authors also discovered that all of the methods (decision tree, linear support vector machine, logistic regression and random forest classifier) can correctly classify the review text into sentiment class, but logistic regression outperforms the others in terms of accuracy. Practical implications The results facilitate halal restaurateurs in identifying customer review behavior. Social implications Sentiment and emotions, according to appraisal theory, form the basis for all interactions, facilitating cognitive functions and supporting prospective customers in making sense of experiences. Emotion theory also describes human affective states that determine motives and actions. The study looks at how potential customers might react to a halal restaurant’s consensus on social media based on reviewers’ opinions of halal restaurants because emotions can be conveyed through reviews. Originality/value This study applies machine learning approaches to analyze and predict customer sentiment based on the review texts toward halal restaurants.

Investigation and prediction of users' sentiment toward food delivery apps applying machine learning approaches

“…Customer feedback is critical for every business, including restaurants. Companies may use customer reviews to learn more about their products (Hossain et al, 2023a). Therefore, a review framework will help the firms discover profitable customers and generate offers that meet customer needs.…”

“…This study used visual analytics approaches to examine the satisfaction level of customers in the airline industry and proved that data analytics approaches outperform other traditional methods. Hossain et al (2022) employed a rule-based SA framework based on support vector machines (SVM) and BaseLine, which extracts the overall review polarity of particular words using a lexicon-based sentiment word dictionary and modifies it in accordance with background information. All of the words in the sentence, which may be negative or positive depending on the type of sentence, establish the polarity of the word (Pashchenko et al, 2022).…”

“…Various strategies or procedures can be employed for sentiment classification (Hossain et al, 2022). The value of the term for expressing sentiment and the significance of the document were the two criteria on which Deng et al (2014) presented a novel word weighting approach.…”

“…As a consequence, future studies may uncover even more linkages between the conception of website quality and future research. Sixth, future studies may look at new research from the UCC, OIBB and OCBB that examines contemporary trends like COVID-19 (Sheth, 2020), the new-age digital revolution (Lim, 2022), customers' sentiments (Hossain and Rahman, 2022; Hossain et al. , 2022; Hossain and Rahman, 2022), emotional and normative aspects of customers (Pashchenko et al.…”
