Abstract:

To constructed  person entity global schema in structured web pages,a method of dynamic construction with SVM is proposed, it has two stages.The first stage is to transform person entity instances from the same data source to person entity local schema.The second stage is to map person entity local schema to person entity global schema with the SVM classifier.Our method can adapt to the change of data sources and ensure the completeness of the global model.Through experiments,the effectiveness and feasibility of the construction algorithm are verified and the stability of the global schema with increasing of structured web pages is studied.

Key words: SVM;person entity local schema;person entity global schema;structured web pages
