ation in effective. Use the method of machine learning to gains the effective knowledge from Corpus , supporting the text information processing is already bee putaional linguisticsa mainstream technology. The tagged corpus is the technical foundation.The target of this text tagging tool design is the processed corpora(text). Taking the single piece of text for users to tag entities, relations, events, and show intermediate results during tagging process . culminating in the preservation of tagging documents processed xml language to the output format for storage. The tool39。s functional annotation including tagging the entities, the events, the relations labeled the tagging off text , remind users the tagging progress, and dealing the intermediate results processing and preservation.The paper will describe and discuss over the design and realization of this interactive text tagging tool. Firstly, detailed theoretical backgrounds will be given。 secondly, analysis of this tool and general structure for it and the full descriptions about the realization of each model will be introduced。 finally, the defects of the design of the tool and improvement to its future development will be given and a summary of the structure and the performance of the system will be delivered as well.
