Rule engine is a good way of knowledge representation and inference. It has been extensively studied and used in artificial intelligence. However, because of its low computational efficiency and the limitation of single machine's capacity, it cannot deal well with big data. In order to address this problem, we propose a distributed implementation of the rule engine based on message-passing model. It is designed to make use of multiple machines in a computing cluster to deal with a large amount
