In this paper, we propose a principle-based approach, combining a corpus-based approach and a knowledge-based approach. There are two parts of a principle: (1) Structure: such as verb frames, address patterns; (2) Statistics: mostly related to collocation and frequency. The method is based on a pipeline of four main stages, allowing to contribute to automatically building ontologies from text corpora, aimed to extract relations between words from the unstructured text.
