Preclinical...
Information extraction (IE) is a main approach for constructing database from free text corpus and for automatic collecting information. Frame semantic tagging is suggested to be the base for rule-building in IE. IE based on frame semantic tagging uses a uniform approach to guide the process of IE. Processing at a finer granularity level, the approach has a universal appeal for IE in domains showing...
The combination of TF and DF, which is used as the method of feature selection, and TF-EDF algorithm, which is used as feature weighting, are frequently used in the text categorization. But for a small training set, the combination of TF and DF will filter out many low-frequency words which have a strong capability of the feature discrimination. Hence the weight is directly influenced. In this paper,...
The Chinese FrameNet Project is creating a lexical resource for Chinese, based on the principles of Frame Semantics and supported by corpus evidence. Due to the fact that syntactic and semantic role labeling (SSRL) is very necessary for deep natural language processing, a method based on cascaded conditional random fields (CCRFs) is proposed for the SSRL task, and the CCRFs model is trained to label...
