In line with the general trend in artificial intelligence research to create intelligent systems that combine learning and symbolic components, a new sub-area has emerged focuses on combining machine (ML) components techniques developed by Semantic Web (SW) community – Machine Learning (SWeML for short). Due its rapid growth impact several communities last two decades, there is need better unde...
