Abstract：This paper promotes a method which collects the non-taxonomic relation from the Chinese patents' texts. Firstly, it analyzes the syntax of abstract texts, then constructs the sub-sentences extraction rules by domain sentence,character sentence, module & craft sentence and effect sentence. Secondly, artificially labels the terms of sub-sentences by label symbols such as BIEO, creates a scale of training data set. Thirdly, learns the training data and extracts the new data by CRFs. Finally, analyzes the experiment results and verifies the validity of the method.
