Indonesian News Crawler
This project was created as part of completing a final assignment at Budi Luhur University, with a focus on a web-based hoax news detection application. I did web crawling on several Indonesian news source websites such as Antara News, JPNN, Ministry of Communication and Information, Kompas, Tribunnews, Global Arrow, and several other news sources. Some news sources are still in the development stage due to time constraints and technical obstacles such as bugs or restrictions on crawled sites.
