The Research Of Distributed Search Engine Oriented The Theme Of Patent

As playing the vital role in view of the patent information application in the scientific research and patent service many aspects,Accurately and fastly retrieves the patent information may enhance the research efficiency greatly, reduces the funds investment, enhances the technical research and development, patent work quality。In development patent strategy and patent research development work ,the technology policy-making organ , enterprise, university, development facility, patent commissioning, patent examination can't leave the patent information. Constructs the search engine based on global various technical colleges advantage organization patent information (US,EP,JP,TW,CN). This system is composed by five parts. They are spider,searcher,analyzer, indexer and duty manager.Involves essential technology:spider load equalization,sort,parallel processing model,buffer mechanism and so on. As the search engine processes the patent information data quantity is extremely huge,moreover every year also by astonishing speed growth. The distributional parallel processing search engine coordinates computation processing with certain machines. The distributional parallel method may obtain the better natural price ratio,processing potency,security and extension .This article elaborates constructs one kind based on the distributional parallel computation technology model construction of web search engine. Uses the distributional parallel programming pattern,duty distribution and SPMD model. Uses the function decomposition, geometry decomposition,iteration decomposition technology. The thread is on popular way in parallel programming. Uses Java thread and the thread group programming model in parallel programming. The message transmission to the distributional parallel programming is effective, Message transmission in the distributed computing use Java socket way.
