Abstract

This study aims to evaluate and compare the performance of two recommendation system approaches, namely Collaborative Filtering (CF) and Content-Based Filtering (CBF), in providing relevant product recommendations to users in an e-commerce context. The dataset used consists of 120 data including 90 relevant and recommended products (True Positive), 20 recommended but irrelevant products (False Positive), and 10 relevant but not recommended products (False Negative). Based on the calculation results, both methods show a precision value of 0.818 and a recall of 0.900. This means that approximately 81.8% of products recommended by the system are truly relevant, while 90% of the total relevant products are successfully recommended to users. The F1-score value obtained of 0.857 illustrates a good balance between the accuracy and completeness of the recommendations generated by the system. Furthermore, to measure the level of rating prediction error, the Mean Squared Error (MSE) and Root Mean Squared Error (RMSE) metrics are used. The evaluation results show that the CF method has an MSE value of 0.0784 and an RMSE of 0.28, while the CBF method shows an MSE of 0.0961 and an RMSE of 0.31. The lower RMSE value of CF indicates that this method has better accuracy in predicting user preferences than CBF. Overall, both methods show good performance with a low error rate. However, CF proved slightly superior in providing recommendations that match user preferences, so it can be used as a basis for developing smarter and more personalized recommendation systems on e-commerce platforms.

Abstract

Searching for products online is often an inefficient and confusing process, especially when users do not know the exact name of the product or use terms that differ from the search system. Keyword-based searches tend to produce irrelevant results because the system only matches text literally without understanding the meaning. As users increasingly talk to digital devices, voice-based search technology has become a more natural and intuitive alternative. This research aims to develop a semantic-based voicebot supported by Natural Language Processing (NLP) to improve the effectiveness of product searches on e-commerce platforms. The designed system not only recognizes user speech but also understands the context, intent, and semantic meaning of the given commands. The research stages include collecting user voice data, training the Automatic Speech Recognition (ASR) model for voice-to-text conversion, and applying the semantic NLP model for interpreting the context of product searches. The testing was conducted using Indonesian voice commands in a simulated e-commerce scenario. The results showed that the system achieved an average Word Error Rate (WER) of 1.29%, indicating a high level of accuracy in recognizing speech and understanding user intent. The integration between ASR and semantic NLP proved capable of creating a more natural, responsive search experience that resembles the way humans think and communicate when interacting with online search systems.

Abstract

Penggunaan aplikasi chatbot sebagai virtual customer service dapat membantu calon pengunjung toko online sebelum melakukan transaksi karena keterbatasan waktu dalam melayani pelanggan, manusia biasa tidak dapat menjawab pertanyaan atau melayani permintaan pelanggan setiap saat. Dengan menggunakan layanan pelanggan virtual, konsumen yang datang ke toko online dapat berbicara dengan penjual tentang barang yang mereka ingin beli. Teknologi ini sangat membantu menjawab pertanyaan dan masalah pelanggan dengan cepat dan tepat. Aplikasi chatbot menggunakan pengetahuan AIML (Artificial Intelligence Markup Language) yang dilengkapi dengan kecerdasan buatan dengan ontologi yang berbasis semantik. Aplikasi chatbot toko online yang digunakan pada penelitian ini adalah kain batik yang menjual produk batik Malang karena permintaan batik dari Malang sangat tinggi dan belum adanya toko online yang memberikan layanan dengan memanfaatkan layanan pelanggan virtual (chatbot). Pengembangan chatbot yang dilengkapi dengan semantik menggunakan ontologi untuk mengolah pertanyaan yang memiliki arti lebih spesifik, memperoleh akurasi sekitar 97% dari 15 jenis pertanyaan dan jawaban yang relevan, kemudian 10 pertanyaan yang dijawab sesuai dengan pertanyaan yang sering ditanyakan oleh calon pembeli. Penggunaan semantik menggunakan ontologi pada aplikasi layanan pelanggan virtual (chatbot) membantu dalam menjawab pertanyaan yang memiliki kata atau makna yang sama sehingga menghasilkan jawaban yang sesuai dengan pertanyaan.
