Abstract: Information extraction 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 information extraction.Information extraction based on frame semantic tagging uses a uniform approach to guide the process of information extraction.Processing at a finer granularity level，the method has a universal appeal for information extraction in domains showing strong semantic rules.A system called BAIE（Book Abstract Information Extraction system），which is based on frame semantic，is designed and used to extract information from book abstract.The result shows that the approach is feasible and has practical promise.

Key words: information extraction, frame semantic, extraction rules
