Sayoeti is the PR's assistant of Komisi Pemberantasan Korupsi(KPK) that powered by Artificial Intelligence. He helps KPK by watching all mass media in Indonesia and provide sentiment analysis of the mass media.
This is one of component that Sayoeti built on. Basically, sayoeti-core is
created to answer the following question:
Human: Given a document, is this document about corruption news in Indonesia? (Yes/No)
Sayoeti: Yes, it is.
Learn more here https://sayoeti.xyz (Indonesian).
We use supervised learning method here. Sayoeti need to learn from corpus of corruption news first. Example of corpus from Kompas.com and Liputan6.com can be found here.
To decrease the bias we need to remove commonly used words in Indonesian
like dan & di that have no meaning in our context. To do this, use
Indonesian stopwords.
Sayoeti only tested on x86_64. Compiled using gcc.
