Research And Implementation Of Intellectual Property Retrieval System

Patent information in the current society is the preferred competitive intelligence resources, it contains a huge stock of knowledge. Fully exploit the use of patent information and technical help to improve existing technologies, discovery of new areas of technology. However, the current sharp increase in the number of patents, relying on artificial means to find a useful patent information and patent analysis for rapid and effective, is almost impossible.Patent Information Retrieval System is to help you in many patent resources to find the resources they need. Patent Information retrieval accuracy and quasi-full-rate and index files depends on the dictionary library has a direct and important relationship. If the dictionary database can contain all the terms of patent information, patent search that the full rate of accuracy and a certain high standard. In this article we will introduce a term extraction technique, Harbin Institute of Technology of Intelligent Technology and Natural Language Processing Laboratory of the dictionary file as a general dictionary database, extracted from the raw data out of the patent jargon, the formation of the term dictionary database. General dictionaries and terminology databases together as a dictionary database dictionary database index file generated.Taking into account the patent of the original text very large amount of information in the database generated during the term dictionary, we use C language as the algorithm development language. In the patent search business, we use B/S structure, only with the Java language as a business development language. Dictionary of terminology in the library generation process, we have several more critical algorithms:mutual information, so neighbors and to find duplicate strings. C language algorithms can be relatively high rate of reading text, and support for large file operations.Finally, the design and implementation of the patent search system and a simple analysis to "Nokia mobile" as key words, to come out of patent search and patent examples.
