Abstract


Patent Information in the current society is the preferred competitive intelligence resources , it contains a huge stock of knowledge . Fully tap and use of patent information helps technicians to improve existing technology, the discovery of new technology. However, the current rapid growth in the number of patents , patent relying on artificial means Find useful information , and make rapid and effective patent analysis , is almost impossible . Patent information retrieval system is to help everyone in numerous patents resources to find the resources you need . Patent information retrieval accuracy and quasi- full-rate and index files depends on the dictionary library has a direct and important relationship . When the dictionary database can contain all the words of patent information , patent search that the accuracy and quasi- full rate would certainly high. In this article we will introduce a term extraction technique , with Harbin Institute of Computer Science of Intelligent Technology and Natural Language Processing Lab dictionary file as a general dictionary database , from the patent raw data extracted terminology , terminology dictionary form library . General dictionaries and terminology dictionary as a common repository index file generated dictionary libraries. Taking into account the original text of the patent very large amount of information , terminology dictionary database is generated in the process, a few more key algorithms: suffix array , take repeated strings and mutual information , using the C language as algorithm development language , C language the algorithm can be done relatively high speed read text , and support for large file operations ; while in patent search services, we use the B / S architecture , the use of the Java language as a top business development language. In the terminology dictionary database generation process . Finally , the design implements a patented retrieval system and a simple analysis functions , with \
