Improving Graph-Based Movie Recommender System Using Cinematic Experience

Abstract

With the advent of many movie content platforms, users face a flood of content and consequent difficulties in selecting appropriate movie titles. Although much research has been conducted in developing effective recommender systems to provide personalized recommendations based on customers’ past preferences and behaviors, not much attention has been paid to leveraging users’ sentiments and emotions together. In this study, we built a new graph-based movie recommender system that utilized sentiment and emotion information along with user ratings, and evaluated its performance in comparison to well known conventional models and state-of-the-art graph-based models. The sentiment and emotion information were extracted using fine-tuned BERT. We used a Kaggle dataset created by crawling movies’ meta-data and review data from the Rotten Tomatoes website and Amazon product data. The study results show that the proposed IGMC-based models coupled with emotion and sentiment are superior over the compared models. The findings highlight the significance of using sentiment and emotion information in relation to movie recommendation.

Understanding postal delivery areas in the Republic of Korea using multiple unsupervised learning approaches

“…It is effective in discovering more latent information by exploiting graph clustering methods in recent studies [32,33]. To do so, the data can be converted into a graph, with nodes representing postal delivery zones and edges constructed by comparing the similarity of two nodes.…”

Natural Language Processing for Analyzing Online Customer Reviews: A Survey, Taxonomy, and Open Research Challenges

“…Since online reviews increasingly include visual information, multimodal techniques that analyze text and images are crucial. Previous research [85,113] have recognized the usefulness of multimodal techniques in sentiment analysis. These methods go beyond text analysis to picture sentiment analysis.…”

Enhancing Personalized Educational Content Recommendation through Cosine Similarity-Based Knowledge Graphs and Contextual Signals

“…Indeed, there exists an active research domain dedicated to exploring recommender systems grounded in knowledge graphs. Their application spans diverse sectors, including travel websites [25][26][27], virtual museums [28][29][30], biomedical platforms [31][32][33], e-commerce platforms [34][35][36], and film portals [37][38][39]. Across these studies, as explicitly highlighted in recent comprehensive reviews [40,41], the prevalent methods for knowledge graphinfused recommender systems in the literature encompass embedding-based strategies, connection-oriented approaches, and propagation-derived methodologies.…”
