are interested by the information users. The shallow parsing technology in sentence semantic analysis is the most popular method in the IE system. Most of IE systems use such technology to catch the information points in the text. Then, after post processing, such as coreference analysis or repeatedfacts clearing, all the filtered information points were put into slots of a wellstructured template. All the filled templates bine the database which will be outputted. The output data can be read by human being or transfer to an automatic analysis program to process. During the research of the IE system, we know it is veryimportant to have the enough technology backup. The ability of nature language processing, largescale programming system development and some very serious knowledge base, such as syntactic and semantic dictionary and treebank corpus are the necessary parts of the backup. Today, a practically largescale Information Extraction system with the ability of easy domaintr
