| Abstract: | With the yearly increase in the amount of patent data,it is more and more difficult to get target patent effectively,because how to keep the balance between the rate of accuracy and the rate of founding actual patents is always the most challenging part for research.Based on patent data of 3G in DII(Derwent Innovations Index) database,results and differences of traditional theme search and manual code search have been compared.The data analyses close to the actual extent of the situation in two different statistical methods with the same patent data have been done,and the results show that the retrieval and analysis methods used in this paper get more reliable conclusions,which have some practical significance. |
