simhash算法的java实现simhash-java.zip

simhash-java ============ A simple implementation of simhash algorithm by java. ### Features:<br /> 1. compute the simhash of a string<br /> 2. compute the similarity between all the strins by build smart index, so We can deal with big data.<br /> ### How to use: - run Main with inputfile and outputfile.<br /> - The format of inputfile(see src/test_in): one doc eachline with the utf8 charset.<br /> - The format of outputfile(see src/test_out): <br /> - start //start flag<br /> - first line // doc<br /> - sencode lien // doc1\tdist the dist is the hamming distance between doc and doc1 <br /> - end //end flag<br /> ### Future: 1. Build the project to a runnable jar.<br /> 2. Improve the performace under big data.<br /> ### Note: 1. Before run Main.java, you should choose a better analyzer instead of BinaryWordSeg!
