Abstract

The growth of e-commerce in the fashion sector has driven the need for systems that can help users discover products more efficiently amid an abundance of available choices. This study aims to implement a smart recommendation system based on content-based filtering on the Dinara Konveksi e-commerce website using the TF-IDF (Term Frequency–Inverse Document Frequency) method and cosine similarity.The dataset consists of 35 active products registered in the Dinara Konveksi e-commerce system. The data used consists of product attributes including name, category, description, variant colors, and sizes, which are combined into text documents and processed through preprocessing steps comprising case folding, tokenization, and stopword removal. Feature weighting is performed using TF-IDF to generate a vector representation for each product, while cosine similarity is used to measure the degree of similarity between products. The system produces two types of recommendations: similar product recommendations displayed on product detail pages, and personalized recommendations tailored to users' purchase history, shopping cart, and product view history. The implementation uses a two-tier architecture consisting of a Python script with scikit-learn for batch computation and a PHP service as the runtime interface. Evaluation results show a Precision@4 of 0.75, Recall@4 of 0.60, F1-Score of 0.67, and a Hit Rate of 1.00. The developed system is capable of providing relevant and responsive product recommendations while supporting a more personalized shopping experience for users of the Dinara Konveksi website.

Abstract

The development of the digital world that continues to increase at this time makes people accustomed to the concept of digitization and technology, even now it has become a necessity. These developments need to be balanced with encouragement for users to better utilize the use of technology through the role of digital literacy. One of the efforts made to encourage the creation of digital literacy is by utilizing technology to support activities that can increase knowledge and improve people's reading and writing literacy. This will make technology users better at using technology and provide other benefits in increasing digital literacy, where increasing digital literacy is currently one of the government targets that has been pursued in various activities to build a society that is not only technology users but also able to utilize technology through their cognitive abilities such as writing so that they are not only able to operate technological devices. This research focuses on making reading and writing applications that can be used by all technology users so that they can foster public interest in reading and writing. In addition, this application will also provide a solution to the sluggish growth of book sales by publishers through the marketplace. Application users can enjoy reading and writing anywhere and anytime and make it easier to search and purchase literacy books. This application was developed using waterfall software development and has gone through a testing stage where all the designed features are already running as specified.
